Basic Keto Layer Cake

This is not cake. This is Cake Simulator.

If you’re trying to avoid carbs for the holidays, and need some cheats to get past the dessert trap, here’s a nice way to fool your brain into thinking it’s getting sugar. This Basic Keto Layer Cake recipe has zero blood sugar impact for me. It has never knocked me out of ketosis (NTTAWWT). Everybody is a little bit different with sweeteners, so I recommend using one you know is good for you. The erythritol/stevia blends are the best options I’ve found.

Like most of the things we eat around here, this cake is very specific to our family’s allergy needs. This recipe is made without nuts, grains, or dairy.

Basic Keto Layer Cake

A basic cake that can be modified for any taste or occasion
Prep Time20 minutes
Cook Time20 minutes
Course: Dessert
Servings: 16


  • 4 8" round cake pans
  • hand mixer
  • parchment paper


  • 18 large eggs separated, room temperature
  • 1 tsp cream of tartar
  • 1 1/2 cups tiger nut* flour sifted
  • 1 cups erythritol/stevia blend I use Pyure or Swerve
  • 1 tsp baking soda
  • 1/2 cup melted butter or lard coconut oil is another good fat for those who have no allergies
  • 1/2 tsp salt I use Redmond's Real Salt


  • Heat oven to 325° F
  • Grease just the bottoms of four 8" round cake pans, then line the bottoms with parchment paper.
  • In a very large bowl, combine egg whites and cream of tartar.
  • With a hand mixer, beat the egg whites until thoroughly thickened to a smooth and glossy consistency.
  • In another very large bowl, combine the rest of the ingredients: egg yolks, tiger nut flour, sweetener, baking soda, melted fat, salt, and any additional flavorings you'd like to use. (See other possible additions in notes.)
  • Mix well with hand mixer.
  • Fold egg whites into the batter mixture. This is best done with about 1/4 of the fluff folded in at a time, very gently, until fully incorporated.
  • Divide evenly into the cake pans.
  • Bake at 325° for 20 minutes, or until firm but still spongy in the middle. Don't overcook!
  • Remove from pans and cool completely on baking racks. Cake releases from pan easily after running a butter knife around the edges. If allowed to cool in the pans, the texture is less enjoyable.
  • Frost with choice of frostings. I use either a 7-minute sugar-free frosting or Buttercream frosting made with ghee (I'll get a recipe posted ASAP. Pinkie swear.)


I've made this cake with several variations, and it adapts easily to most flavorings and types of frosting. Try adding any of these at Step 5:
  • 2 Tablespoons apple extract/flavoring + 2 Tablespoons cinnamon
  • 1/4 cup cocoa powder + 1 Tablespoon vanilla extract
  • 2 Tablespoons Vanilla extract
  • 1/4 cup cocoa powder + 1 Tablespoon cherry flavoring
  • 1/4 cup cocoa powder + 1 Tablespoon coffee extract
  • You get the idea. Use your imagination! 
*Tiger nuts are not nuts, but a kind of tuber. I've found this flour substitute to be very gentle on the digestion.
