# What You'll 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
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
16 - 1/4 teaspoon vanilla extract
# Directions:
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. Mix until evenly combined.
04 - Drop spoonfuls of the cinnamon swirl mixture onto the cake batter. Using a toothpick or knife, gently swirl through the batter to create marbled pattern.
05 - Microwave on high for 60 to 90 seconds, until the cake is just set. The center should appear cooked but remain slightly moist; avoid overcooking.
06 - While the cake cools slightly, beat together cream cheese, milk, powdered sweetener, and vanilla until smooth and creamy.
07 - Spread the cream cheese topping evenly over the warm mug cake. Serve immediately.
