# What You Need:
→ Cake Batter
01 - 1/4 cup vanilla protein powder
02 - 2 tablespoons oat flour
03 - 1/4 teaspoon baking powder
04 - 1/4 teaspoon ground cinnamon
05 - 1 tablespoon granulated sweetener
06 - Pinch of salt
07 - 3 tablespoons milk
08 - 1 large egg white
09 - 1/2 teaspoon vanilla extract
→ Cinnamon Swirl
10 - 1/2 tablespoon melted butter or coconut oil
11 - 1 tablespoon brown sugar or coconut sugar
12 - 1/2 teaspoon ground cinnamon
→ Cream Cheese Topping
13 - 1 1/2 tablespoons light cream cheese, softened
14 - 1 teaspoon milk
15 - 1/2 tablespoon powdered sweetener or sugar
16 - 1/4 teaspoon vanilla extract
# Steps:
01 - In a microwave-safe mug of at least 10 fluid ounces, combine protein powder, oat flour, baking powder, cinnamon, sweetener, and salt. Mix thoroughly until well blended.
02 - Add milk, egg white, and vanilla extract to the dry mixture. Stir continuously until a smooth, lump-free batter forms.
03 - In a small bowl, combine melted butter, brown sugar, and cinnamon, stirring until fully incorporated.
04 - Drop spoonfuls of the cinnamon mixture over the batter surface. Using a toothpick or knife, gently swirl the mixture through the batter in a decorative pattern.
05 - Microwave on high power for 60 to 90 seconds, until the cake is set but the center remains slightly moist. Avoid overcooking to maintain moisture.
06 - While the cake cools briefly, whisk together softened cream cheese, milk, powdered sweetener, and vanilla extract until the mixture reaches a smooth, spreadable consistency.
07 - Spread the cream cheese topping generously over the warm mug cake and serve immediately for optimal flavor and texture.
