How to Make Protein Cake
Preheat Oven: Begin by preheating your oven to 350°F. Don t forget to spray an 8â round cake pan with cooking spray, ensuring an easy release after baking.
Mix Dry Ingredients: In a medium mixing bowl, combine oat flour, vegan chocolate protein powder, cocoa powder, baking powder, baking soda, and salt. Stir until well combined, creating a harmonious blend of dry goodness.
Combine Wet Ingredients: In a large mixing bowl, whisk together maple syrup, almond milk, Greek yogurt, avocado oil (or melted coconut oil), eggs, and vanilla. Blend until everything is smooth and creamy.
Combine Mixtures: Gently pour the dry mixture into the wet ingredients. Stir until fully combined, ensuring there are no lumps left. The batter should be smooth and velvety.
Bake the Cake: Pour the batter into your prepared cake pan. Bake in your preheated oven for 35 minutes, or until a toothpick inserted into the center comes out clean.
Cool Down: Once baked, remove the cake from the oven and allow it to cool completely in the pan before transferring it to a wire rack, if desired.
Make Ganache Frosting: While your cake is cooling, prepare the frosting. In a microwave-safe bowl, add the dark chocolate chips and microwave in 15-second increments until fully melted, which should take around 45-60 seconds. Once melted, stir in 3 tablespoons of almond milk until smooth and glossy.
Frost & Serve: Spoon the creamy ganache frosting generously over the top of the cooled cake. Slice into pieces and enjoy your blissfully indulgent Protein Cake!
Optional: Top with fresh berries for an extra burst of flavor.
