How to Make This Vanilla Protein Cake

Follow these simple steps to bake your delicious vanilla protein cake:

  1. Preheat your oven to 350°F (175°C) and prepare an 8” round cake pan or an 8×8” baking pan by lining the bottom with parchment paper and spraying the sides with cooking spray.
  2. In a bowl, combine whole wheat flour, half of the vanilla protein powder, baking powder, baking soda, and salt. Set aside.
  3. In a large bowl, beat together softened butter and the remaining protein powder using an electric mixer until well combined.
  4. Add in the Greek yogurt, almond milk, and egg, mixing until smooth.
  5. Gradually fold the dry mixture into the wet ingredients using a spatula, ensuring not to over-mix, as this could toughen the cake due to the protein powder and gluten from the flour.
  6. Pour the batter into the prepared baking pan.
  7. For the optional oat streusel, mix melted butter with the oatmeal mixture in a separate bowl and sprinkle it on top of the cake batter.
  8. Bake on the center rack for 25-30 minutes, or until a toothpick inserted in the center comes out clean and the cake springs back when touched.
  9. Once baked, transfer the cake to a cooling rack to cool completely before serving.
