# 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

11 - 1/2 teaspoon ground cinnamon

→ Cream Cheese Topping

12 - 1 tablespoon light cream cheese, softened

# Directions:

01 - In a microwave-safe mug, whisk together protein powder, oat flour, baking powder, cinnamon, salt, and granulated sweetener until combined.
02 - Add the 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 to create the swirl mixture.
04 - Pour the 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 wattage.
06 - In a small bowl, mix softened cream cheese, Greek yogurt, and powdered sweetener until smooth and creamy.
07 - Spread or pipe the cream cheese topping over the warm mug cake. Serve immediately.

# Expert Advice:

01 -
  • You get genuine cinnamon roll satisfaction without spending an hour in the kitchen or derailing your nutrition plan.
  • It tastes decadent and comforting while delivering more protein than most breakfast pastries combined.
  • The whole thing happens in a single mug, which means minimal cleanup on mornings when you're already running behind.
02 -
  • Microwave times vary wildly, so err on the side of underdone your first attempt; you can always add 15 seconds, but there's no fixing a rubbery, overcooked cake.
  • The cream cheese must be softened before mixing, or you'll end up with lumps that no amount of whisking can fix, which I discovered the hard way.
03 -
  • Room-temperature ingredients mix more smoothly, so pull your egg and milk out of the cold 10 minutes before you're ready to make this; it sounds fussy but changes the texture noticeably.
  • If you're batch-prepping the dry mixture, store it in a small container and just add the wet ingredients when you're ready to eat—this turns it into a five-minute breakfast on autopilot.
