Recipes   Sweets    


  • 3 cups almond flour
  • 1/3 cup whey protein powder
  • 2 tsp grain-free baking powder
  • 1/4 tsp salt
  • 1/2 cup unsalted butter, softened
  • 3/4 cup Swerve Sweetener
  • 3 large eggs, room temperature
  • 1 tsp vanilla extract
  • 1/2 cup almond or cashew milk, unsweetened
Pastry Cream
  • 1 1/4 cups whipping cream
  • 3 egg yolks
  • 6 tbsp confectioner’s Swerve Sweetener
  • Pinch salt
  • 2 tbsp butter, cut into two pieces
  • 1 1/2 tsp vanilla extract
  • 1/2 tsp xanthan gum
Chocolate Ganache
  • 2/3 cup whipping cream
  • 1/4 cup confectioner’s Swerve Sweetener
  • 2 1/2 ounces unsweetened chocolate, finely chopped
  • 1/2 tsp vanilla extract


  1. Preheat oven to 325F and grease a 9x9 square baking pan.
  2. In a medium bowl, whisk together the almond flour, whey protein powder, baking powder and salt.
  3. In a large bowl, beat butter with sweetener until light and fluffy. Beat in eggs, one at a time until well combined. Beat in vanilla extract.
  4. Beat in half of the almond flour mixture, then beat in nut milk. Beat in the remaining almond flour mixture until well combined. Spread batter in prepared baking pan.
  5. Bake 25 to 30 minutes, or until golden brown around the edges and the top is just firm to the touch. Remove and let cool in pan. Once cool, use the end of a wooden spoon to poke holes all over the cake.
Pastry Cream
  1. Bring whipping cream to a simmer in a medium saucepan over medium heat. In a medium bowl, whisk egg yolks with sweetener and salt.
  2. Slowly whisk about half of the hot cream into the yolks to temper, then return the yolk/cream mixture back to the saucepan and cook until thickened, 4 to 5 minutes more, whisking constantly. Watch it carefully and do not let it curdle.
  3. Remove from heat and whisk in butter and vanilla extract. Sprinkle surface with xanthan gum and whisk vigorously to combine. Let cool about 10 minutes, then pour all over cake and tap pan firmly on counter to allow pastry cream to sink into holes.
  4. Refrigerate 2 to 3 hours, until pastry cream is mostly set.
Chocolate Ganache
  1. In a small saucepan over medium heat, combine cream and sweetener. Whisk until sweetener is dissolved and cream comes to just a simmer.
  2. Remove from heat and add chopped chocolate and vanilla extract. Let sit 5 minutes to melt chocolate and then whisk to combine. Pour over chilled cake and refrigerate another 20 to 30 minutes, until set.

  • Erika

    Do you have the nutritional info for this recipe? Thank you!

    • Swerve

      Hi Erika, the nutrition facts are now posted! Thanks for visiting the site :)

  • Gayle

    Can the whey protein be omitted without affecting the taste?

    • Swerve

      Hi Gayle! Yes, you can omit the protein powder and it will not change the taste. Your cake just might turn out a bit more dense. Hope this helps! Enjoy the recipe!

  • Dianne

    Hi, is the butter for the cake and pastry cream salted butter or unsalted butter?

    • Swerve

      Hi Dianne! Unsalted butter should be used for the cake. Thank you for visiting our website!

  • Catherine

    Thanks so much for this recipe - looks great. It sure would be nice if you had a "printer friendly" version. I just printed out the recipe and it took five pages with an enormous "font" making it almost impossible to follow. I will try copying and pasting to Word.

  • Mary Manello

    Hey Carolyn! I have a few boxes of Swerve cake mix, in my pantry (2 vanilla and 2 chocolate). Would one of them work, rather than making the homemade cake recipe? Thanks!

    • Swerve

      Hi Catherine, You should be able to make this recipe with the vanilla cake mix!

  • Amber

    Hi, Could the whey protein be substituted with collagen powder, or something else? This looks delicious!

  • cynthea

    Does it need to be almond milk?

    • Swerve

      HI Cynthea. You can use regular milk if you prefer.

  • Eliana

    This recipe is amazing! Thank you.

  • Linda

    This looks heavenly! What can I use to replace the xantham gum? Is it ok to omit?

    • Swerve

      You can try it but it may alter the texture and may not hold together as well. You could try gelatin! Hope that helps!

  • Dawn Garcia

    It looks amazing
