This Keto Apple Cake, or low carb apple crumb cake if you want to get fancy with it, is lightly sweet and flavored generously with cinnamon. The buttery apple topping is also loaded with cinnamon as well as the light crunch of toasty walnuts for texture. It’s one of our favorite keto apple desserts!
You can easily adapt this keto apple cake into a handy muffin format – making it the perfect portable low carb breakfast or snack!
Living in Belize, it’s not easy to get into the spirit of the changing seasons when it comes to food. It’s hot all the time, and there is no feeling of Fall on the way here. Maybe because I grew up in New England, my internal clock still knows that apples are coming into season and that the days are getting cooler though.
We will be spending almost the entire month of October in the states and I can’t wait! I’m so looking forward to crisp mornings, changing seasons, and wearing sweaters and boots again – even if only for a short time!
In the meantime, I’m using my imagination to get inspired to cook some keto apple recipes for you guys, starting with this delicious Keto Apple Cake!
It was a strange contrast that my house smelled like Fall in New England, while the view outside my kitchen window was still of palm trees and blue Caribbean seas – but the end result was delicious and transported me home for a few minutes.
No matter where you live and what the weather is there, I hope that you’ll have the same experience when you try this Low Carb Apple Cake.
From the amazing smells, to the warm flavors and textures – it doesn’t get much more fall inspired than this recipe!
You can easily make this recipe into keto apple muffins, just reduce the cooking time accordingly – I’ll add instructions to the bottom of the recipe for that.
This keto apple cake is lightly sweetened, so it’s not overpowering and can even be eaten for breakfast. It’s still plenty sweet for dessert though, and if you wanted to add a scoop of low carb vanilla ice cream I wouldn’t hold it against you!
If you find after baking it that you wish this keto apple cake was a little sweeter, you can sift some Swerve confectioners mixed with a little cinnamon over the top and that should do the trick!

Keto Apple Cake – Low Carb and Gluten Free
- Total Time: 47 minutes
- Yield: 9 servings 1x
- Diet: Diabetic
Description
A keto apple cake that is flavored with cinnamon, apples and chopped walnuts. Perfect as a snack or with your morning coffee!
Ingredients
For the Cake:
- 6 tablespoons butter
- 1/3 cup Erythritol sweetener (I use Swerve)
- 2 eggs
- 1 teaspoon vanilla extract
- 1 teaspoon ground cinnamon
- pinch of salt
- 1 cup super fine blanched almond flour
- 1/3 cup coconut flour
- 2 teaspoons baking powder
- 1/4 teaspoon xanthan gum
- 1/2 cup unsweetened almond milk
For the apple streusel layer:
- 3 tablespoons butter
- 1 cup granny smith apples, peeled and chopped into 1/2 inch pieces
- 1/4 cup Erythritol sweetener (I use Swerve)
- 1 teaspoon ground cinnamon
- 3/4 cup almond flour
- 1/4 cup walnuts, chopped
- pinch of salt
Instructions
To make the cake layer:
- Preheat the oven to 375 degrees.
- Cream the butter and sweetener together until smooth and fluffy.
- Add the eggs one at a time, beating well after each, then add the vanilla extract.
- In a medium-sized bowl, combine the almond flour, coconut flour, cinnamon, baking powder, xanthan gum and salt and mix well.
- Add the dry ingredients to the wet ingredients and mix.
- Pour in the almond milk and mix until just blended.
- Spread the batter into a greased 9×9 baking pan.
To make the apple streusel layer:
- Melt the butter in a medium skillet.
- Add the apples, cinnamon and sweetener and cook for 2 minutes, stirring the entire time.
- Remove from the heat and stir in the almond flour, pinch of salt and chopped walnuts. Stir well until a crumbly dough forms.
- Spoon the topping evenly over the cake batter and spread out.
- Bake the cake in a 375 degree oven for 35 minutes. If you find the topping getting too brown, cover it loosely with parchment or aluminum foil for the final 10 minutes.
- Remove from the oven and cool before slicing into 3 inch squares.
- Alternatively, you can bake these in 9 large muffin cups for about 20 minutes at 375 degrees (F) or until a knife inserted in the center comes out clean.

Thanks so much, so happy that you really loved this recipe!
Beth says
Can you substitute the Granny Smith apple with other types of apples? Thanks. Looking forward to trying this recipe.
Mellissa Sevigny says
Yes, any apple will work for this recipe.
Erin Maurer says
Love your recipes! This is just lovely. I recently discovered the keto apple trick where you cut out the seeds of zucchini, chop it up, let it sweat a bit in a pan and use it just like apples. Fewer carbs, and with the fall spices and zucchini tastes just like apples. I’ve made “apple” butter, “apple crisp” and all kinds of things with it… And now this beautiful dessert!!! Everyone loves it! I used pecans instead of walnuts and cream instead of almond milk. We had some keto vanilla ice cream on the side. Thank you thank you and bless you for all of your hard work!!! 🥰🥰🥰
Mellissa Sevigny says
Thanks so much Erin, I haven’t tried the zucchini trick yet but will have to see how it tastes since so many people love it!
Delia Narvaiz says
The cake was really great, however the streusel part was a little dry. Could you bake as an upside cake?
Desiree says
Is it possible to sub butter with oil?
Luba Zak says
Can you use Monkfruit sweetner instead?
I greatly prefer the taste.
Mellissa Sevigny says
Yes
Mellissa Sevigny says
If it was bitter I can almost guarantee your almond flour or butter has gone rancid. Nothing else would account for a bitter flavor that I can think of.
CL says
Hi. Is it okay to use Fuji apple (red apple) instead? And is there any substitute to xanthan gum? Thank you!
Mellissa Sevigny says
A sweeter apple will have a tad more carbs, you can omit the xanthan gum but the cake will be a litter more crumbly.
Asad Mammood says
Hi Mellissa, I am from UK (England) as would love to try make this amazing recipe. Any chance of the recipe in Metric rather than Imperial measurements.
As with past experiences with measurements in imperial, the recipes always turn out horribly wrong. ( big difference conversion from weights, liquids etc…)
