What makes this gluten free coffee cake special?

The crumb of this delicious cake is dense, but incredibly tender and moist. It's really a golden cake, instead of a gluten free vanilla cake.

Traditional cakes with a more open crumb, like vanilla cake, are typically made with a liquid in the batter like milk. This coffee cake has just 2 tablespoons of milk—and the rest of the moisture comes from sour cream.

The dense texture of this golden yellow cake combined with the huge cinnamon and sugar crumbles on top make it perfect for enjoying along with a hot cup of coffee or tea—or with a tall glass of milk. The cake is perfectly sweet, but not so sweet that the brown sugar crumble topping feels like it doesn't belong or like it's “too much.”

Ingredients in a gluten free crumble topping

• Unsalted butter: melted and cooled slightly, this is the buttery base of any crumble topping
• Brown sugar: adds sweetness, richness, and depth of flavor
• Granulated sugar: adds more sweetness, and also helps the crumble topping crisp in the oven
• All purpose gluten free flour blend: this is what adds structure and keeps the crumble topping from melting into the rest of the cake; your blend must have some xanthan gum or the crumble won't keep its shape

Ingredients in the gluten free coffee cake base

• All purpose gluten free flour blend, including xanthan gum: This provides structure and texture for the cake; you must use one of my recommended blends or the cake ingredients won't combine properly or bake with the right texture
• Cornstarch: Adds some lightness to the blend if you're using Better Batter's classic blend, like I am. If you're using Cup4Cup, in place of cornstarch, use 2 tablespoons (18 g) more of the flour blend
• Baking powder: Provides rise
• Baking soda: Neutralizes the acid in the sour cream and helps the cake brown
• Salt: Brings out all the other flavors and offsets the sweetness a bit
• Ground cinnamon: Adds warmth and depth of flavor, but you can leave it out if you'd prefer more plain butter flavor
• Butter: Adds richness, tenderness, and flavor
• Sour cream: Adds moisture, tang, and tenderness.
• Granulated sugar: Adds tenderness and sweetness
• Milk: Just a touch of milk lightens the crumb a bit and makes the cake batter easier to spread in the pan
• Vanilla: adds depth of flavor
• Eggs: Add rise and act as a binder for all the other ingredients

How to make gluten free coffee cake

Make the crumble topping

• Whisk together the gluten free flours, brown sugar, granulated sugar, and salt.
• Mix in melted butter for easy blending.
• Chill the topping to create big crumble pieces.

Make the cake batter

• Whisking together the dry ingredients (gluten free flours, baking powder & baking soda, & salt).
• Beat the butter, sour cream, milk and granulated sugar in a large mixing bowl, then the eggs.
• Mix in the dry ingredients by hand for a thick batter.

Assemble the batter, top with crumble, & bake

• Transfer the cake batter to a prepared cake pan and spread it into an even layer.
• Break up the chilled crumble and scatter on top.
• Bake the cake at 350°F until it no longer jiggles in the center.
• Allow the cake to cool, then slice and serve!

How to store gluten free coffee cake

This lovely gluten free coffee cake will keep at room temperature in an airtight container for up to 3 days. You can also freeze it as you'll see below.

Can I freeze this gf coffee cake?

Yes! This coffee cake freezes quite well after baking, once it's completely cooled to room temperature.

You can cut the cake into squares and serve it when it's still a bit warm. But to freeze baked goods, they must be completely cool.

If you freeze anything that's still warm, it will form condensation on the outside that will freeze completely solid. And as the frozen condensation melts out of the freezer, it makes the cake soggy.

I prefer to slice the cooled coffee cake into squares, and then wrap each leftover square tightly in freezer-safe wrap. Then, defrost at 50% power in the microwave or on the kitchen counter.

If you'd like the cake to taste extra fresh, even after being frozen, you can toast it lightly after it's defrosted. Don't let it toast long enough to dry out, and gluten free coffee cake will be good as new!

Ingredient substitution suggestions

This cake is versatile enough that you can make some tweaks to it when you're catering to dietary requirements other than gluten free.

Gluten free dairy free coffee cake

There is a lot of butter in this recipe, both in the crumble topping and in the cake itself. The best replacement for the butter in both places is probably Melt or Miyoko's Kitchen brand vegan butter.

For the crumble topping, if you can't use vegan butter, try using Spectrum nonhydrogenated vegetable shortening.

In place of sour cream, try using a good quality nondairy sour cream. You can also use plain Greek-style yogurt in place of sour cream.

And remember, go with Better Batter not Cup4Cup, as Better Batter is dairy free while Cup4Cup is not.

Egg-free coffee cake

There are two eggs in this coffee cake recipe, and you might be able to replace each of them with one “chia egg” each. For each, place 1 tablespoon ground white chia seeds + 1 tablespoon lukewarm water into a small bowl, mix, and allow to gel.

If you make this recipe both egg-free and dairy-free, it will be a gluten free vegan coffee cake.

About the cornstarch in this gluten free coffee cake

If you can't have corn, try using arrowroot powder or even potato starch in place of cornstarch. If you can't have cornstarch, you'll have to avoid using Cup4Cup at all, since it is made with a lot of cornstarch.

If you can have corn and you're already using a higher starch all purpose gluten free flour blend, like Cup4Cup, replace the 18 grams of cornstarch in this recipe with an equal amount of that high starch flour blend.

Instructions 

• Preheat your oven to 350°F. Line an 8-inch square baking pan with parchment paper and set it aside.

For the crumble topping

• The topping must be prepared first, so it can chill.
• In a medium-size bowl, place all the ingredients in the order listed, mixing to combine after each addition.
• Cover the bowl that holds the raw topping. Place the bowl in the refrigerator to chill until firm.

For the cake batter

• In a medium-size bowl, place the flour, xanthan gum, cornstarch, baking powder, baking soda, salt, and optional cinnamon, and whisk to combine well. Set the bowl aside.
• In a large bowl with a handheld mixer or the bowl of a stand mixer fitted with the paddle attachment, place the butter, sour cream, granulated sugar, milk, and vanilla, and beat well on medium speed until very smooth. Add the eggs, and beat until just combined.
• Add the dry ingredients to the bowl of wet ingredients and mix by hand until just combined. The batter will be very thick, since our liquid is mainly sour cream.

Assemble and bake the cake

• Scrape the batter into the prepared pan and smooth into an even layer with a wet spatula. Press the spatula down in the corners to eliminate any air pockets.
• Remove the chilled crumble topping from the refrigerator. Uncover the topping, and use the tines of a fork to break up the mixture into irregular pieces.
• Scatter the crumble pieces evenly on top of the cake batter. Press down gently to help the topping adhere to the batter.
• Place the cake pan in the center of the preheated oven. Bake for about 40 minutes, until the center does not jiggle in the center when the pan is shaken from side to side gently.
• A cake tester inserted into the center should come out mostly clean. Do not overbake or the bottom will burn.
• Remove the pan from the oven and allow the cake to cool in the pan for 10 minutes or until it's just table enough to transfer.
• Lift the cake out of the pan by the parchment paper liner, and place it on a wire rack. Pull out the parchment paper from underneath the cake to allow the cake to be exposed to the air while it cools completely.
• Slice into 9 equal squares and serve.
