# What You'll Need:

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

→ Cream Cheese Topping

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

# Directions:

01 - In a microwave-safe mug, whisk together protein powder, oat flour, baking powder, cinnamon, salt, and granulated sweetener until evenly distributed.
02 - Add egg and milk to the mug, then mix thoroughly until a smooth, lump-free batter forms with no dry pockets remaining.
03 - In a small bowl, combine melted butter, brown sugar, and cinnamon, stirring until well blended.
04 - Pour the cinnamon swirl mixture in a spiral pattern over the mug cake batter, then gently swirl using a toothpick or fork to create a marbled effect.
05 - Microwave on high power for 60 to 90 seconds, or until the cake is just set and springs back when gently touched. Timing may vary depending on microwave wattage.
06 - In a small bowl, whisk together 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 and serve immediately for optimal texture and flavor.

# Expert Tips:

01 -
  • It's genuinely faster than making coffee, and you get a warm, satisfying dessert-for-breakfast without the guilt.
  • 23 grams of protein means you'll actually stay full, not just satisfied for ten minutes.
  • The cream cheese topping transforms a basic mug cake into something that tastes intentional and indulgent.
02 -
  • Your microwave's power matters enormously; I learned this the hard way when I zapped it for 90 seconds in my friend's industrial-strength microwave and ended up with cake rubber.
  • The batter should be thick but pourable; if it's too thick, add milk one tablespoon at a time because a dense batter won't rise properly in such a short cooking time.
  • Cold cream cheese won't spread smoothly and will tear the warm cake, so let it sit out or microwave it for just 10 seconds beforehand.
03 -
  • Invest 20 seconds in whisking the dry ingredients thoroughly to avoid those pockets of baking powder that taste like chalk when you bite into them.
  • The swirl is what makes people think you tried harder than you did, so take that extra moment to create visible ribbons rather than mixing it all together.
