For the Berry Cake

½ cup (60g) all purpose flour

1 scoop (40g) I-PLX Vanilla Frosting Protein Powder

¼ cup (60g) swerve granular sweetener*

1 tsp. Baking powder

¼ tsp. Salt

3 whole eggs

2 tbsp. (28g) light butter, melted

⅔ cup (150g) nonfat, plain Greek yogurt

1 tsp. Vanilla extract

1 cup mixed berries

For the Peanut Butter Frosting

1 cup (227g) plain, nonfat Greek yogurt

½ cup (64g) peanut flour

½ cup (60g) Swerve confectioners sweetener


*Swerve is a sugar free sweetener that measures 1:1 with sugar. It can be found in the baking aisle of most grocery stores or online on Amazon.

**Light butter is found near the regular butter in the grocery. It has only 4g of fat per tablespoon compared to 11 grams in regular butter.


  1. Preheat the oven to 325F. Grease and line a 9×5 loaf dish with parchment paper.
  2. Mix flour, protein powder, sweetener, baking powder, and salt in a large bowl. In a separate bowl add eggs, melted butter, Greek yogurt and vanilla extract.
  3. Combine wet and dry ingredients and gently stir together until a smooth batter forms. Fold in berries.
  4. Pour batter into the prepared baking dish. Bake at 325F for 25-35 minutes or until a knife comes out clean. The center should be slightly under-done, as it will continue to cook slightly once out of the oven. Be careful not to overbake.
  5. While the cake is cooling, make peanut butter frosting. Mix all ingredients in a bowl until a smooth, creamy frosting comes together.
  6. Top cooled cake with peanut butter frosting, cut into 4-5 slices and enjoy!
