Units Scale

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


To make the cake layer:

  1. Preheat the oven to 375 degrees.
  2. Cream the butter and sweetener together until smooth and fluffy.
  3. Add the eggs one at a time, beating well after each, then add the vanilla extract.
  4. In a medium-sized bowl, combine the almond flour, coconut flour, cinnamon, baking powder, xanthan gum and salt and mix well.
  5. Add the dry ingredients to the wet ingredients and mix.
  6. Pour in the almond milk and mix until just blended.
  7. Spread the batter into a greased 9×9 baking pan.

To make the apple streusel layer:

  1. Melt the butter in a medium skillet.
  2. Add the apples, cinnamon and sweetener and cook for 2 minutes, stirring the entire time.
  3. Remove from the heat and stir in the almond flour, pinch of salt and chopped walnuts. Stir well until a crumbly dough forms.
  4. Spoon the topping evenly over the cake batter and spread out.
  5. 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.
  6. Remove from the oven and cool before slicing into 3 inch squares.
  7. 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.
