When you bite into this sugar free apple cake, I am certain you’ll be so glad you made it. It’s pretty low-key, and there aren’t a ton of ingredients or directions.
- Almond Flour - Don’t use just fine almond flour; it’s best to combine it with coconut flour. Using the two flours together helps balance the oiliness of the almond flour. If you want a bit of a heartier texture you can use almond meal.
- Coconut Flour - You’ll just need ½ cup of coconut flour to get the best texture.
- Coconut Oil - Use refined coconut oil, so it doesn’t taste like coconut. Butter flavored coconut oil works well too.
- Sour Cream - Substitutions would be Greek yogurt or even cottage cheese.
- Joy Filled Eats Sweetener - I use a combination of xylitol, erythritol, and stevia in my low carb recipes. I find that this combination tastes the most like sugar while being economical because you use half the amount of most other sweeteners.
- Eggs - If you want to lighten this up a bit you can use all egg whites.
- Vanilla - Vanilla extract is a must when baking to highlight the other flavors.
- Baking Powder - A leavening agent to help the cake rise. Look for aluminum-free baking powder.
- Salt - A pinch of salt enhances the other flavors of the keto apple cake.
Apple Cinnamon Filling:
- Granny Smith Apples - Using fresh Granny Smith apples gives you a tart and delicious flavor. They are my favorite to bake with, especially for this sugar free cake. Or you can sub in jicama using this method.
- Brown Sugar Sweetener - You can use commercially packed brown sugar sweetener, or you can make your own by mixing 1 teaspoon of molasses into 1 cup of sweetener.
- Butter - It will need to be melted for the best results.
- Almond Flour - I add a little bit into the filling to balance some of the moisture
- Cinnamon - A must for any apple recipe!
How To Make Sugar Free Keto Apple Cake
There are only 4 steps to make this low carb keto apple cake, and they are all super simple. This reminds me of an apple cider cake or a decadent apple coffee cake to serve for brunch!
Step One: Warm the oven to 350 degrees F. and prepare a baking pan by spraying it with cooking spray.
Step Two: Combine the flour, coconut oil, sour cream, sweetener, eggs, vanilla, baking powder, and salt together in a large bowl. Spread evenly in the 9x13 inch casserole dish or cake pan.
Expert Tip: The batter is going to be super thick, and that is normal.
Step Three: Mix together the apples, brown sugar sweetener, melted butter, almond flour, and cinnamon.
Spread the sugar free apple mixture on top of the cake batter.
Step Four: Bake the almond flour apple cake for 40 minutes or until it’s firm to the touch. You can insert a toothpick in the center to test doneness. It should come out dry when done.
Can I Use Different Apples in Keto Apple Cake?
Yes, you sure can. I am a fan of Granny Smith in general for baking because they hold their shape, so that’s usually what I reach for. They are also one of the lowest carb apples. There isn't too much difference in the amount of carb in an apple so you can really just use the ones you prefer.
However, there are many other varieties of apples that would work well in a low carb apple cake. The biggest thing you need to consider is choosing something that won’t just turn to mush as it bakes. Pink Lady, Honeycrisp, Braeburn, Honey Gold, and Gala are all great choices too.
Can I Leave The Peels On The Apples?
No, the peel won't soften enough and will leave the cake with an odd texture so it’s a good idea to remove the skin. It only takes a few extra minutes and will give you a much better low carb grain free cake in the end.
How Many Carbs in an Apple?
There are 25 carbs in an apple and 4.4 grams of fiber.
This brings us to the next question...
Are Apples Keto?
Not really. And definitely not in large quantities. BUT I believe that small amounts of fruit can be eaten in moderation. This recipe uses 2 cups of apples which is about 2-2.5 apples divided between 18 pieces. That means that each piece has approximately ⅛th of an apple. This is enough to get that apple flavor and texture with minimal carbs.
If you would like an even lower carb option you can make this keto apple cake with jicama instead by using the method I use in my Keto Apple Crisp.
Can I use a Bundt Pan?
I haven't tried this recipe in a bundt pan but I don't see why it wouldn't work provided you grease the pan really well. I would put ⅓ of the batter, then the filling, and then the rest of the batter and gently swirl it a bit. A low carb apple bundt will take longer to bake. My guess is 45-50 minutes at 350.
- Preheat oven to 350. Spray a 9x13 baking pan with cooking spray.
- Mix together all the cake ingredients. Spread in the prepared pan. This is a VERY thick batter.
- Mix together the filling ingredients. Spread on top of the cake batter.
- Bake at 350 for 40 min or until the cake is firm to the touch. A toothpick inserted in the center will come out with a few moist crumbs when it is done.
