High-Protein Cinnamon Roll Mug Cake (Printable Version)

A warm, protein-rich mug cake with cinnamon swirl and creamy topping, ready in minutes.

# 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

# Method:

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, 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 well blended.
04 - Pour the cinnamon swirl mixture in a spiral pattern over the mug cake batter, then gently swirl with a toothpick or fork to create marbling.
05 - Microwave on high for 60 to 90 seconds, or until the cake is just set and springs back when lightly touched. Cooking time varies by microwave.
06 - In another small bowl, mix cream cheese, Greek yogurt, and powdered sweetener until the mixture is smooth and creamy.
07 - Spread or pipe the cream cheese topping over the warm mug cake and serve immediately.

# Expert Hints:

01 -
  • It tastes like an indulgent cinnamon roll but actually fills you up with real protein.
  • Seven minutes total means you can have hot, satisfying cake before your day gets away from you.
  • The cream cheese topping is tangy and rich enough to feel like a treat, not a shortcut.
02 -
  • Every microwave is different, so start at sixty seconds and add time in fifteen-second bursts rather than blasting it for two minutes and ending up with a rubbery cake.
  • If your cream cheese comes straight from the fridge, it won't spread smoothly, so let it sit for a minute or thin it with a tiny bit of milk.
03 -
  • Add half a teaspoon of vanilla extract to the batter for a flavor lift that reminds you even more of a real bakery cinnamon roll.
  • If you're watching carbs, swap the oat flour for almond flour and use stevia instead of sugar; the cake still rises and tastes great.
