Fluffy microwave cake with cinnamon swirl and cream cheese frosting, packing 23g protein per serving.

# What You'll Need:

→ Mug Cake Base

01 - 1 scoop vanilla protein powder
02 - 2 tablespoons oat flour
03 - 1/2 teaspoon baking powder
04 - 1/4 teaspoon ground cinnamon
05 - Pinch of salt
06 - 1 tablespoon granulated sweetener
07 - 1 large egg
08 - 3 tablespoons milk

→ Cinnamon Swirl

09 - 1/2 tablespoon unsalted butter, melted
10 - 1 tablespoon brown sugar
11 - 1/2 teaspoon ground cinnamon

→ Cream Cheese Topping

12 - 1 tablespoon light cream cheese, softened
13 - 1/2 tablespoon Greek yogurt
14 - 1/2 tablespoon powdered sweetener

# Step-by-Step Guide:

01 - In a microwave-safe mug, whisk together protein powder, oat flour, baking powder, cinnamon, salt, and granulated sweetener until evenly blended.
02 - Add egg and milk to the mug. Mix thoroughly until a smooth batter forms with no dry pockets remaining.
03 - In a small bowl, combine melted butter, brown sugar, and cinnamon, stirring until well incorporated.
04 - Pour the cinnamon swirl mixture in a spiral pattern over the mug cake batter. Gently swirl with a toothpick or fork to create a marbled effect.
05 - Microwave on high for 60 to 90 seconds, or until the cake is just set and springs back when lightly touched. Timing may vary depending on microwave power.
06 - In another small bowl, combine cream cheese, Greek yogurt, and powdered sweetener. Whisk until smooth and creamy.
07 - Spread or pipe the cream cheese topping over the warm mug cake. Serve immediately while warm.

# Expert Tips:

01 -
  • You get a warm, spiced dessert in the time it takes to pour coffee, no oven drama required.
  • Twenty-three grams of protein means this actually keeps you full instead of leaving you hungry thirty minutes later.
  • The cinnamon sugar swirl tastes sinfully indulgent while secretly being pretty good for you.
02 -
  • Every microwave is different, so start with 60 seconds and check before adding more time, because overcooked mug cake tastes like rubber and there's no fixing that.
  • Softening your cream cheese matters more than you'd think, because cold cream cheese won't mix smoothly and you'll end up with lumpy topping instead of that luxe frosting texture.
03 -
  • Measure your ingredients by weight if you have a kitchen scale, because this recipe's success actually depends on precision and eyeballing can throw off the batter consistency.
  • Make the cream cheese topping before you microwave so it's ready to spread immediately when the cake comes out, because applying cold topping to a warm cake is what creates that perfect melt-together situation.
