High-Protein Cinnamon Roll Mug Cake (Printable Version)

Protein-packed mug cake with cinnamon swirl and cream cheese topping, ready in 7 minutes for breakfast or snack.

# 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

# Directions:

01 - In a microwave-safe mug, whisk together protein powder, oat flour, baking powder, cinnamon, salt, and granulated sweetener until evenly 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 for the swirl topping.
04 - Pour the swirl mixture in a spiral pattern over the mug cake batter. Gently swirl with a toothpick or fork to create marbling effect.
05 - Microwave on high for 60 to 90 seconds, or until the cake is just set and springs back when touched. Timing may vary depending on microwave wattage.
06 - In another small bowl, mix cream cheese, Greek yogurt, and powdered sweetener until the mixture reaches a smooth, spreadable consistency.
07 - Spread or pipe the cream cheese topping over the warm mug cake. Serve immediately while the cake is still warm.

# Additional Tips::

01 -
  • It delivers 23 grams of protein without tasting like a fitness supplement, just warm cinnamon comfort.
  • The cream cheese topping turns a simple mug cake into something that feels indulgent and special.
  • You can make it in one mug with almost no cleanup, which means more time enjoying and less time scrubbing.
  • The cinnamon swirl creates pockets of sweet spice that hit differently in every bite.
02 -
  • Microwaves vary wildly in power, so check your cake at 60 seconds and add time carefully because overcooked mug cakes turn rubbery and sad.
  • Let the cream cheese sit out for a few minutes before mixing or it won't blend smoothly with the yogurt.
  • If your batter looks too thick, add a splash more milk because a slightly looser batter cooks up fluffier.
03 -
  • Use a mug that holds at least 12 ounces because the batter rises as it cooks, and you don't want a microwave mess.
  • Soften the cream cheese in the microwave for 10 seconds if you forgot to leave it out, but watch it closely so it doesn't melt.
  • Swap the cinnamon swirl for a peanut butter swirl by melting a tablespoon of peanut butter with a little sweetener, and you'll have a whole new flavor.
  • If you like it extra gooey, undercook it slightly so the center stays soft and molten.
