Keto Apple Fritters


Filled with an apple cinnamon flavor, these keto apple fritters are gluten-free and fried to produce a crunchy crust around this sweet, buttery low carb donut.

The apple fritter donut is a favorite, classic donut loved by many and it’s easy to make low carb without using apples!

These keto apple fritters should be called zucchini fritters because we use zucchini place of apples in order to cut down on the net carbs; although, chayote squash can be used as well.

To give these keto donuts an apple flavor, we use a concentrated apple extract mixed with lemon juice and cinnamon to mimic a crisp granny smith apple. This method works well for making keto apple pie too!

These keto apple fritters are delicious topped with the creamy glaze or even with melted butter on top. It makes for a tasty breakfast with a hot cup of coffee.

    Zucchini in place of apple for low carb recipes

    Zucchini is used in the place of apples in many keto recipes because it has a neutral flavor while imparting a similar texture and appearance to an apple. The neutral flavor allows you to manipulate it by adding apple flavor extracts to yield an delicious apple taste in this keto apple fritter but without all of the carbs.

    If you absolutely don’t want to use zucchini in place of apples in this recipe, you can probably get away with using an apple in this recipe. Just make sure you adjust the macros.

    Apple flavoring

    In order to mimic the apple taste in apple fritters without adding actual apples, which are too high in carbohydrates, we use apple flavoring. There are many types of apple flavoring and extracts to choose from. My favorite is the flavor from a granny smith. These flavors are the closest to traditional apple fritters which use granny smith apples. I have also Fuji apple flavoring too.

    The secret to perfect keto donuts

    One of the main ingredients in this apple fritter recipe and the secret to fluffy keto donuts is the protein powder. It helps these donuts to from structure, provide flavor and helps them rise. You can use whey protein powder or a vegan protein powder.

    Storage information

    This recipe for these gluten free apple fritters makes 18 donuts! Unless you are having a party, there is no way you can eat all of those keto donuts in one setting.

    For leftover fritters, I recommend you store them in a paper bag at room temperature. This will help keep them crunchy on the outside and soft on the inside.

    1. Hello! Video shows to add 1/4 cup water, but not seeing it in printed recipe. New to keto baking so needing direction on whether to add water or not. Love all the recipes I’ve tried so far. Thanks!

      1. Thank you for pointing this out! I updated the recipe. It should include 1/4 cup of water. I mis-read my recipe notes when I inputted this recipe in.

    2. Not sure what I did wrong, but they did not hold together. At all.
      The only change I made was 2% milk for nut milk. I ended up with a lot of what looked like piles of fried bread crumbs. 🥺🥺

      1. I’m sorry they didn’t turn out for you. The reason why is that your oil was too hot. When you cook them, if you start to notice they are disintegrating when frying, the oil is way too hot. Lower it down and try again. Hope that helps.
