  • In a medium mixing bowl combine almond flour, protein powder, powdered erythritol, and baking powder.
  • Add egg yolks, almond milk, oil, and vanilla to dry ingredients.
  • Beat with an electric mixer on low to medium speed until combined.

  • Gently pour the batter into 2 8 inch greased cake pans.
  • Bake for 12 to 15 minutes or until golden brown and toothpick comes out clean in the center.
  • Cool completely before removing from pans.
  • Custard: In a medium saucepan over low heat, add heavy cream and butter until the cream has bubbles around the top edge of the heavy cream.
  • Do not boil.
  • Add sweetener and xantham gum.
  • Add egg yolks to a bowl.
  • Temper the egg yolks by adding some of the hot cream mixture to the egg yolk bowl, mix in.
  • This will bring the egg yolks up to the temperature of the cream mixture so it won’t scramble when you add it to the hot heavy cream mixture.
  • Add the egg yolks to the heavy cream mixture, whisking consistently.
  • When the mixture begins to thicken.
  • Remove from heat and stir in vanilla.
  • The custard should coat the back of a spoon.
  • Transfer the custard to a bowl and place in the refrigerator for at least 1 hour.
  • This can be made ahead of time and just store in the fridge up to 24 hours.
  • Ganache: Break up unsweetened chocolate and butter.
  • Place in a bowl and set aside.
  • Place the heavy cream in a medium saucepan over medium heat.
  • Do not cover.
  • Whisk the cream every so often to keep from breaking.
  • Watch the cream closely and remove from the burner as soon as it gets bubbles around the top edge just before the boiling point.
  • Do not boil.
  • Pour over chocolate and butter.
  • Whisk until fully combined.
  • It will take a couple minutes of whisking to incorporate...
  • be patient it will come together.
  • Add stevia and whisk it into the smooth chocolate mixture.
  • You can now pour it over the cake so that it covers the whole top and drips down the sides.
  • To assemble the cake: Remove cooled cakes from the pans.
  • Put on the custard onto the bottom cake layer and spread evenly across.
  • Be sure not to get too close to the edge because it will spill out when you put the top layer on.
  • Top with the second layer of cake.
  • Pour chocolate ganache over and down the sides of the cake.
  • Store in the refrigerator.
  • Notes We use erythritol granules and then we just powder it in a coffee grinder.
