How do you make a gluten free chocolate cake from scratch?

There are many ways to make chocolate cake from scratch, and most of them aren’t any harder than making it from a mix. All the mix does is provide you with already-measured dry ingredients like flour, cocoa powder, sugar, and salt.

When you’re using a mix, you still have to add eggs, oil, and often water. As long as you’re adding eggs, oil, and water, you may as well add some sour cream, too, and make it into this cake.

That’s really all it takes. You have to provide the pan either way, right? And bake it in your oven.

Just whisk the dry ingredients (flour, cocoa powder, salt, baking soda, and sugar) and you have your chocolate cake mix. Make a well in the center, and add the wet ingredients and mix. Pour into the pan, smooth the top, and bake.

What makes this chocolate cake special?

Sometimes, you just need a rich, dark gluten free chocolate cake that you make in 1 bowl, without even melting any chocolate. Usually, to get a really rich chocolate cake or cupcake, your best bet is to use both melted dark chocolate and cocoa powder.

But this one bowl gluten free chocolate cake gets the job done with just the right mix of cocoa, sour cream, and oil instead of butter. It’s also dense, but never heavy.

This cake is tender enough that you can make it days ahead of time. You can even store it in the refrigerator without its drying out too much.

How to make a gluten free chocolate layer cake

This is the cake you make when it’s someone’s birthday and you don’t want to disappoint—but you haven’t planned ahead. But if you’re making it as a celebration cake, you may want to make a layer cake.

No problem. Simply double each ingredient of the recipe to make two layers. Use a large bowl, or measure everything out into two bowls.

Place half of the batter into each of two prepared 9-inch cake pans. Smooth the top, and place them in a 350°F oven. If the oven isn’t really large (like mine isn’t), after about 20 minutes rotate the pans with one another so everything bakes evenly.

How to make the easiest chocolate frosting

Chocolate ganache sounds fancy, but it’s deceptively simple. When you make just chocolate ganache, it’s not really a frosting. But if you whip it, you’ve got the easiest rich chocolate frosting.

Make the ganache by heating heavy whipping cream (or coconut cream, if you’re dairy free) until simmering. Then, pour the simmering cream over chopped chocolate.

Allow the two ingredients to sit for a bit, until the chocolate begins to melt. Stir until the chocolate is melted, the liquid is fully incorporated, and the mixture is smooth. That’s chocolate ganache.

Whipped chocolate ganache

To make it from simple chocolate ganache, use the proportions specified in the recipe below. Once the ganache has cooled to room temperature, place it in the refrigerator to chill until it can be scooped with a spoon. That should take a couple hours.

Remove the chilled ganache from the refrigerator. Whip it with a hand mixer until it’s thick, light and fluffy, and add a bit of confectioners’ sugar if you’d like it a bit sweeter, and a bit thicker.

Ingredients and substitutions

Not only is this one bowl gluten free chocolate cake easy, it also doesn’t have a lot of other potential allergens in it. No wonder it’s one of my very best gluten free chocolate cakes.

Dairy

There isn’t as much dairy in this cake as you might expect. Since cocoa powder works well to create chocolate richness with oil, there isn’t any butter in this recipe. Just be sure the chocolate you use in your ganache is dairy-free.

The only dairy in the cake itself is the sour cream. Sour cream can be replaced in baking with plain Greek-style yogurt. If you’re dairy-free, use nondairy yogurt.

If you only have plain regular yogurt, try straining out enough liquid until it’s looks like sour cream. Then measure and use that. If you’re dairy-free, again just use nondairy plain yogurt.

The dairy in the ganache is heavy whipping cream. That can be replaced with coconut creme, if you’re dairy-free.

Just be sure not to use canned light coconut milk, which has added water. Your coconut cream must be from a can, not from a carton of milk which is nearly all liquid.

Eggs

There are 2 eggs in this recipe, and they’re important. But since there are only 2 in a rather substantial cake, you might be able to replace each of them with one “chia egg.”

A “chia egg” is made with 1 tablespoon ground white chia seeds and 1 tablespoon lukewarm water. Just mix them together in a small bowl (times 2, here, for 2 eggs), and allow them to sit until they gel. Then add them when you would add the eggs.

Cocoa powder

Dutch-processed cocoa powder tends to be richer than natural cocoa powder, which is why I prefer it in this recipe. If you only have natural cocoa powder, you can use that without changing anything else.

Natural cocoa powder is not processed with alkali, like Dutch-processed, so it requires a bit of baking soda to offset its acidity. But this recipe already calls for some baking soda.

Prep time: Cook time: Yield: 1 9-inch cake

Ingredients

For the cake
1 1/2 cups (210 g) all-purpose gluten free flour (I used Better Batter)

3/4 teaspoon xanthan gum (omit if your blend already contains it)

14 tablespoons (70 g) unsweetened cocoa powder

1/2 teaspoon kosher salt

1/2 teaspoon baking soda

1 cup (200 g) granulated sugar

3/4 cup (168 g) sour cream, at room temperature

1/2 cup (112 g) neutral oil (vegetable, grapeseed, peanut, canola all work)

2 eggs (100 g, weighed out of shell) at room temperature, beaten

1 teaspoon pure vanilla extract

3/4 cup (6 ounces) warm water (about 80°F)

For the ganache topping
3/4 cup (6 fluid ounces) heavy whipping cream

8 ounces (or 10 ounces, for whipped ganache) dark chocolate, chopped

1 cup (115 g) confectioners’ sugar (for whipped ganache)

Directions

  • Preheat your oven to 350°F. Grease a 9-inch round or square baking pan and set it aside.

  • In a large bowl, place the flour, xanthan gum, cocoa powder, salt, baking soda and sugar, and whisk to combine well. Create a well in the center of the dry ingredients and add the sour cream, oil, eggs, vanilla, and water, and mix to combine well. The batter should be very thickly pourable. Scrape the batter into the prepared pan, smooth into an even layer and place in the center of the preheated oven. Bake until a toothpick inserted in the center of the cake comes out mostly clean or with a few moist crumbs attached (about 30 minutes). Do not overbake. Remove from the oven and allow to cool for 10 minutes in the pan before inverting onto a wire rack to cool completely.

  • While the cake is cooling, make the ganache topping. In a small, heavy-bottom saucepan, heat the heavy whipping cream until it just begins to simmer. Place the chopped chocolate in a medium-size bowl, and pour the hot cream over the chocolate. Allow the cream to sit on the chocolate for about a minute, until the chocolate begins to melt, and mix until the chocolate is melted and the mixture is smooth and glossy.* Pour the warm ganache over the top of the cooled cake, and gently spread toward the edges so the ganache begins to drip down the sides of the cake. Allow to set at room temperature before serving.

  • *To make whipped ganache frosting, use 10 ounces of chopped chocolate with the 6 fluid ounces cream and follow the same instructions. Allow the ganache to cool at room temperature until no longer hot to the touch. Cover and place in the refrigerator until firm enough to scoop with a spoon. Transfer the cooled ganache to a large bowl and beat with a handheld mixer or stand mixer fitted with the whisk attachment until thickened and fluffy. The ganache will also lighten in color. Add the optional confectioners’ sugar and beat until well-combined. Frost as desired.

    Hi Nicole! Thank you so much for all your recipes – I finally feel like I’m cracking the code on my gluten free baking (with your help of course!) Could I use your mock cup for cup blend for this recipe instead of better batter? Thanks so much :)

    • Nicole Hunn
      September 29, 2020 at 10:54 AM

      Of course, Cat! You can always use my mock Cup4Cup blend anywhere a recipe calls for an all purpose gluten free flour. If you’re going to go through the trouble to make the mock Cup4Cup, though, I would make my Better Than Cup4Cup. It’s actually my favorite all purpose blend. :) And thank you for the kind words. Cheers to your continued success!

    Such a lovely and simple cake. Thanks for giving us my husband’s favorite birthday treat, along with the whipped ganache topping. No one ever realizes the cake that they are raving about is gluten free.

    • Nicole Hunn

      I love that, Sheridan. It’s our go-to chocolate cake, and that’s an important thing to have. It sounds like your family agrees! Thanks so much for the nice note.

      You’re very welcome, Louise. I’m afraid it does get harder as they get older. My son is now 16 and it’s just … hard. But hopefully I’ll have more advice for you when your son gets older. :)

    This was absolutely delicious and easy to make, thank you so much. I made this for my son’s 9th birthday today, his first as a coeliac. I am NOT a baker and had purchased all of his previous cakes but I just couldn’t find any suitable options right now. I wasn’t brave enough to try whipping the ganache so kept this as standard. I found it took longer to cook (maybe 10 plus minutes) than the 30 minutes indicated. I am in the UK and so used Doves Gluten-free Plain flour. Despite my lack of experience, it turned out perfectly and I am so grateful, thank you!
    I think your son was a similar age when he was diagnosed, so out of interest what did you do about other children’s birthday parties? We haven’t faced this situation yet due to Covid but wondering whether to just expect him to go without cake or stash some plain cupcakes in the freezer. I appreciate any suggestions on this(particularly any freezable recipes if applicable!) if you have any. Thanks!

      Hi, Louise, I’m so glad you were able to bake your son’s birthday cake. That way, you can make it just as he likes it—and it’s a way to pamper him. At least that’s always how I saw it for my son. Your question about birthday parties is a good one. It was something I struggled with, since my son has always hated being singled out. I would quietly speak to the other child’s mom when I dropped my son off (or call ahead of time to see what they were planning to serve and explain what I needed). Then, I would make some pizza right before the party, wrap it well on a disposable plate (to hopefully make it mimic what they were eating at the party), and bring it to the party warm, if possible. I would also bring cupcakes (my funfetti cupcakes recipe is ideal because they’re “fancy” even without frosting if that’s hard to transport). The cupcakes I would ensure were fully cooled ahead of time. If you want to make that days ahead, just cool completely, wrap tightly, and freeze. Then allow to defrost still wrapped tightly at room temperature before bringing it to the party. Hope that helps!

    Thank you Tiffany for mentioning you used Robin Hood flour and it worked out! I was going to do this recipe but they don’t sell these specific things where I live so not exactly easy to follow. I love comments that show flexibility in baking <3

    I just baked this recipe. I used the Robin hood gluten free flour. It has xanthan gum in it as well. It turned out fairly well. I doubled the recipe and split between four 6″ pans. It baked up in about 35min :)

    • Nicole Hunn
      July 13, 2020 at 7:27 AM

      I’m afraid that’s not one of my recommended flour blends, Tiffany. If you use one of the proper blends, I think you’ll find that the recipes turn out better than “fairly well.”

  • Mira

    this came out great!! I’ve made several GF cakes before with questionable success, and I read something recently about sour cream (or Greek yogurt which is what I used here) being the trick to making sure a gluten free cake doesn’t come out too gummy. I’m glad I searched for that specifically this time because it was delicious! Still a pretty dense cake, but in a good, fudgy kind of way, and not gummy or weird at all. I used bob’s red mill baking flour.

    • Nicole Hunn
      July 6, 2020 at 10:44 AM

      You will have significantly better results if you use a better quality, better-balanced flour blend, Mira. Bob’s Red Mill gluten free flour blend is not either of those things, and it’s the reason you are getting gummy results. Please see my gluten free flour blends page for a full explanation. The key is the right recipe, and the right flour blend. Not sour cream or Greek yogurt!

    Hi Nicole, thank you for this recipe! As a busy mum of three little ones a one bowl cake is the best! I’ve made this today (just the cake without the ganache) (Thursday) for my sister’s birthday on Saturday afternoon – any thoughts on whether it will last ok until then or should I freeze it tonight and take out and add the topping on Saturday morning? Many thanks, Helen

    • Nicole Hunn
      June 25, 2020 at 1:56 PM

      Hi, Helen, Definitely freeze it! Not that it won’t last, but wrap it tightly and freeze it, then defrost at room temperature and it will be good as new when you serve it!

  • Beverley
    June 21, 2020 at 9:13 AM

    Your cake looks delicious! I’m out of gf flour. Could I substitute the same amount, 1 1/2 cups, of regular regular flour? Thx!

    • Nicole Hunn
      June 21, 2020 at 10:18 AM

      I’m afraid that baking with conventional flour is not at all the same as baking with gluten free flour. I really recommend that you find a recipe that is developed for conventional flour, Beverly.

    Do you think the cake would hold up well enough to triple the recipe for a 3 layer cake in 8 inch cake pans? I’m trying to put together a hodgepodge of recipes to create a chocolate covered strawberry cake for my husband’s birthday, and the simplicity of this recipe looks promising plus I just love that you list your ingredients by weight!

    • Nicole Hunn
      June 20, 2020 at 9:05 AM

      Since you’ll be measuring by weight, Amanda (the only way to bake successfully!), I think you could triple the recipe. Depending upon the size of your oven, though, you may have to bake in batches. Lucky birthday man!

    Thanks so much for the wonderful information and recipes you provide! I’d like to make this cake, but I’m out of sour cream – any chance of replacing with Greek yogurt? I have a bunch of that in hand now because we love your pizza and monkey bread recipes!!

    • Nicole Hunn
      June 17, 2020 at 4:28 PM

      Hi, Elyse, You should be able to use Greek yogurt in place of sour cream, yes. I wouldn’t recommend using nonfat yogurt, though, for this cake. It needs the fat!

    Hi Nicole. This looks amazing and I’m actually making it now for my brother’s birthday! Just a query-the video shows you adding vanilla, but it’s not in the ingredient list. I’m adding it anyway but thought I would ask for future reference. :) thank you!

    • Nicole Hunn
      June 8, 2020 at 3:30 PM

      Thank you for pointing that out, Priya. I don’t always add it, to be honest, but it certainly doesn’t hurt! I added it to the ingredients list. Oh, and happy birthday to your brother. This is my family’s go-to chocolate birthday cake. :)

  • CarolM
    June 7, 2020 at 5:26 PM

    This was my 1st time making any form of ganache. I used unsweetened bakers chocolate, and learned the hard way that you meant a semi sweet or bittersweet type dark chocolate, like a bar of 70 or 85%. I’ve added the confectioners sugar and given it a bit of a beat, and it’s edible, but I’ll read up more on ganache before I try it again. Would semi-sweet baking chips work?

    • Nicole Hunn
      June 7, 2020 at 7:12 PM

      Oh no, Carol, never use unsweetened chocolate unless a recipe calls for it! You can’t use chocolate chips to make ganache properly, since they have a fair amount of wax in them. That’s what helps them hold their shape even in the oven.

    Thanks for the great recipe!
    I used this cake to go with a buttercream I just had to try (Tahini honey – tastes like Halva, link to recipe below) but I reduced the sugar to 1/3 cup to make it a darker cake.
    Was not expecting that much of a rise but the tops are trimmed and waiting to be made into a cake sandwich thingie!
    10/10 would make again

    • Nicole Hunn
      June 1, 2020 at 8:15 AM

      Hi, Trish, I would try Lankato monkfruit granulated sugar substitute. It does tend to be drying, though, so you may need to add a bit more liquid. Add it about a teaspoon at a time, and try to match the precise consistency of the batter that you see in the videos.

    Loved the cake-easy and very delicious. Question on the whipped ganache– While icing the cake, the whipped ganache became very stiff. Any ideas as to why? Thank you

    • Nicole Hunn
      May 23, 2020 at 10:38 AM

      Hi, Susan, I’m afraid I can’t possibly know, but whipped ganache has to be thoroughly whipped. Perhaps you didn’t?

    Thank you,

    • Nicole Hunn
      May 18, 2020 at 8:31 AM

      I discuss King Arthur Flour on the gluten free flour blends page, Julie. I’m afraid it isn’t properly balanced, and tends to be gritty, so it won’t work in my recipes. It’s so readily available that I wish it were otherwise, but I’ve tried and tried and just can’t recommend it.
