Time Required: 5 minutes
Step 2: Mix Dry Ingredients
In a large mixing bowl, combine:
- Chocolate protein powder
- Oat flour
- Cocoa powder
- Baking powder
- Baking soda

Whisk thoroughly to ensure the ingredients are evenly distributed and free of lumps.
Intensity Level: Easy
Time Required: 3 minutes
Step 3: Mix Wet Ingredients
In a separate bowl, whisk together:
- Eggs

- Vanilla extract
- Melted coconut oil
Mix until smooth and fully incorporated.
Intensity Level: Easy
Time Required: 5 minutes
Step 4: Combine the Batter
Gradually add the wet ingredients to the dry ingredients.
Stir gently using a spatula until a thick, smooth batter forms. Avoid overmixing, as this can make the cake dense.
The batter should be thick but pourable. If it seems too thick, add 1–2 tablespoons of milk.
Intensity Level: Easy
Time Required: 4 minutes
Step 5: Transfer to Pan
Pour the batter into the prepared cake pan.
Use a spatula to spread the batter evenly and smooth the top.
Tap the pan lightly on the counter to remove any trapped air bubbles.

Step 6: Bake the Cake
Place the cake pan in the center rack of the preheated oven.
Bake for 30–35 minutes, or until a toothpick inserted into the center comes out with only a few moist crumbs.
Avoid overbaking to maintain a moist texture.
Intensity Level: Moderate
Time Required: 30–35 minutes
Step 7: Cool Completely
Remove the cake from the oven.
Allow it to cool in the pan for 10 minutes before transferring it to a wire rack.
Cool completely before frosting.

Tips for Success
Use Quality Protein Powder
The flavor of the protein powder significantly affects the final result. Choose a protein powder you enjoy drinking on its own.
Measure Carefully
Too much protein powder can make the cake dry. Accurate measurements ensure the best texture.
Don’t Overmix
Mix only until the ingredients are combined to maintain a soft crumb.
Check Early
Ovens vary, so begin checking the cake around the 28-minute mark.
Let It Cool
Frosting a warm cake can cause the topping to melt and slide off.
