Ingredients

Scale
  • 1 ½ cups (180g) almond flour
  • ½ cup (60g) vanilla whey protein powder
  • ½ cup (60g) unflavored collagen peptides
  • 1 teaspoon baking powder
  • ¼ teaspoon salt
  • 3 large eggs, room temperature
  • ½ cup (120ml) unsweetened almond milk
  • ⅓ cup (80ml) melted coconut oil
  • ½ cup (100g) granulated erythritol or sugar
  • 1 teaspoon pure vanilla extract
  • Red layer: 2 tablespoons beetroot powder or natural red food coloring
  • Blue layer: 1 tablespoon butterfly pea powder or natural blue food coloring
  • White layer: plain batter
  • Frosting: 1 cup (240g) Greek yogurt or dairy-free coconut yogurt
  • 2 tablespoons honey or maple syrup
  • 1 teaspoon vanilla extract

Instructions

  1. Preheat oven to 350°F (175°C). Grease two 8-inch cake pans and line bottoms with parchment paper.
  2. In a large bowl, whisk together almond flour, vanilla whey protein powder, collagen peptides, baking powder, and salt.
  3. In a separate bowl, beat eggs lightly. Add almond milk, melted coconut oil, erythritol or sugar, and vanilla extract. Whisk until smooth.
  4. Slowly pour wet ingredients into dry ingredients, stirring gently with a spatula until just combined. Add up to 2 tablespoons more almond milk if batter is too thick.
  5. Divide batter equally into three bowls.
  6. Add beetroot powder to one bowl for red layer, butterfly pea powder to second bowl for blue layer, leave third plain for white layer. Mix gently.
  7. Pour each colored batter into prepared pans, layering carefully. Use multiple pans or bake in batches if needed.
  8. Bake for 25-30 minutes. Check doneness with toothpick; it should come out clean or with a few moist crumbs.
  9. Cool cakes in pans for 10 minutes, then transfer to cooling rack to cool completely.
  10. Mix Greek yogurt, honey, and vanilla extract for frosting until smooth. Chill in fridge.
  11. Once cakes are cooled, spread a thin layer of frosting between each colored layer and cover entire cake with frosting.

Notes

Use parchment paper to prevent sticking. Do not overmix batter to keep cake tender. Keep wet ingredients warm but not hot to avoid cooking eggs prematurely. Natural color powders may thicken batter; add extra liquid if needed. Chill frosting before spreading. For vegan version, use flax eggs and plant-based protein powders with dairy-free yogurt frosting.
