These gluten free apple fritters are crispy outside, tender inside, and just sweet enough—with a simple cinnamon sugar glaze.

Why this recipe works
This super simple apple fritter batter, fried in the right oil (you only need something with a high smoke point, like grapeseed oil and/or vegetable shortening), beats any donut, any day. Save the ground cinnamon for the glaze, though, because adding it to the fritter batter turns the inside an unappetizing brown color.
These gluten free apple fritters are made with the simplest batter that's not that different from buttermilk pancakes, just with different proportions and, of course, with diced apples. And instead of cooking them on a skillet, we're frying them.
When you fry them in oil held at a consistent temperature of 350°F, the outside of the batter begins to brown rather quickly, which creates a crispness once they cool. It also seals the inside from absorbing more oil, which prevents any sogginess, and allows the inside to cook gently.
If the oil is much hotter than 350°F, you risk burning the outside before the inside is cooked all the way through. Much cooler, and the fritters won't brown.

Can I bake or air fry this batter instead?
Sadly, no. For making gluten free apple fritters with that classic crisp outside and soft inside with fork-tender apples studded throughout, you must fry the batter in a few inches of oil. The batter is quite wet, so it doesn't bake well.
I know because, when I was testing this recipe, I got the proportions wrong quite a few times before I got them right. Rather than throwing away the batter, I decided to place it in the wells of a muffin tin and bake.
When the batter was too thick, baking it as muffins worked somewhat. I mean, we certainly ate the failures since even if the texture is wrong, the results were edible with these sorts of ingredients.
I do not recommend making this recipe in an air fryer, either. Air fryers are powerful little convection ovens, but they're still a form of baking.
I do think there's potential for my creating a recipe for baked apple fritter-style muffins. But it will take some doing, and I'm not quite there yet. For the time being, if you're looking to bake, not fry, I recommend our recipe for gluten free apple cider donuts, a favorite fall recipe every year.

Which apple is best for apple fritters?
Granny Smith apples are often my choice when I'm making a gluten free apple pie, especially one that calls for baking the apples at a high temperature, for a substantial period. They're very firm and rather tart, so they hold their shape during baking.
Here, we're not baking these fritters, but rather frying them. Since these apple fritters are relatively flat, and not super puffy, they don't fry for that long.
If you do use a very firm apple like Granny Smith, just cut it into a smaller dice. That way it will still become tender during frying. Almost any apple, other than a golden delicious apple with very tender flesh or a red delicious apple that tends to be mealy, will work at a regular dice. I really like Empire and Macintosh apples for this recipe.

What's the best gluten free flour to use?
There is no need for xanthan gum in this recipe. To make things as simple as possible, the recipe calls for a combination of an all purpose gluten free flour (like Better Batter or my mock Better Batter blend, both discussed at the link) and cornstarch.
The cornstarch serves to lighten the flour so that the batter is properly soft, but not runny. If you're using a higher starch blend like Cup4Cup or my mock Cup4Cup blend, in place of 2 tablespoons of cornstarch, please use 2 tablespoons more of the blend.
If you'd prefer, you can use my gum-free gluten free flour blend in place of both the all purpose gluten free flour blend and the cornstarch. You'd need 1/2 cup (70 g) of that gum-free blend, which would be made up of 46 grams superfine white rice flour + 15 grams potato starch + 9 grams tapioca starch/flour. If you use this blend, please use 1 tablespoon less buttermilk.

Ingredients and substitutions
Dairy free
In place of buttermilk, whether you're dairy-free or you've simply run out of buttermilk, my advice is similar. Use half milk (nondairy if you're dairy-free) and half plain yogurt (nondairy if you're dairy-free).
“Souring” milk (nondairy or not) with a bit of acid like lemon juice or vinegar simply doesn't make a liquid that resembles the viscosity of actual buttermilk. Resist the urge!
Egg free
Since there is only one egg in this recipe, you should be able to use a “chia egg.” In a small bowl, place one tablespoon of ground white chia seeds and one tablespoon of lukewarm water, then mix and allow it to gel.
Cornstarch free
In place of cornstarch, you can try using arrowroot. If you are corn-free, you'll also need a confectioners' sugar that doesn't contain cornstarch.

















These were delicious!! Definitely making these again!
WOW! Now I have to resist making these over and over with the large quantity of fresh fall apples I got today!!
I cannot remember the last time I fried. Actually, I do. It was over a decade ago, and it was a disaster. I think your confidence, Nicole, gave ME confidence to forge ahead.
Thank you. They were actually easy (TOO EASY!) & are absolutely delicious. I won’t tell you how many we just ate immediately after the icing hardened.
That’s so lovely to hear, Kim! I’m so glad you felt confident enough to give deep frying a try. Definitely filter that oil and use it again!
