# Components:

03 - 1/2 teaspoon baking powder
04 - 1/4 teaspoon ground cinnamon
05 - Pinch of salt

# Directions:

01 - In a microwave-safe mug, whisk together protein powder, oat flour, baking powder, cinnamon, salt, and granulated sweetener until well combined.
02 - Add the egg and milk to the mug, mixing 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 the mixture is evenly blended.
04 - Pour the cinnamon-sugar mixture in a spiral pattern over the batter, then gently swirl using a toothpick or fork to create marbling.
05 - Microwave on high power for 60 to 90 seconds, until the cake is just set and springs back when lightly touched.
06 - In another small bowl, blend cream cheese, Greek yogurt, and powdered sweetener until smooth and spreadable.
07 - Spread or pipe the cream cheese topping over the warm cake and serve immediately.

# Expert Tips:

01 -
  • It's genuinely done in seven minutes, which means you can have warm cake while your coffee is still hot.
  • The protein keeps you full for hours, so you won't be hunting for snacks by mid-morning.
  • It tastes like dessert but actually supports your fitness goals, not sabotages them.
02 -
  • Microwaves vary wildly, so even 15 seconds too long turns the cake from fluffy to tough—start conservatively and add time if you need it.
  • The cream cheese topping must be softened before mixing, or you'll get grainy chunks that refuse to blend smoothly with the yogurt.
03 -
  • Use a tall, narrow mug rather than a wide one so the cake rises up instead of spreading thin and cooking unevenly.
  • If your cream cheese is too cold, warm it gently in the microwave for 10 seconds before mixing—it'll blend with the yogurt instantly instead of fighting you.
