High-Protein Cinnamon Roll (Printable)

Single-serve protein cake with cinnamon swirl and creamy topping, ready in minutes.

# What You'll Need:

→ Cake Batter

01 - 1/4 cup vanilla protein powder
02 - 2 tablespoons oat flour
03 - 1/4 teaspoon baking powder
04 - 1/4 teaspoon ground cinnamon
05 - 1 tablespoon granulated sweetener
06 - Pinch of salt
07 - 3 tablespoons milk
08 - 1 large egg white
09 - 1/2 teaspoon vanilla extract

→ Cinnamon Swirl

10 - 1/2 tablespoon melted butter or coconut oil
11 - 1 tablespoon brown sugar
12 - 1/2 teaspoon ground cinnamon

→ Cream Cheese Topping

13 - 1 1/2 tablespoons light cream cheese, softened
14 - 1 teaspoon milk
15 - 1/2 tablespoon powdered sweetener
16 - 1/4 teaspoon vanilla extract

# Directions:

01 - In a microwave-safe mug, combine protein powder, oat flour, baking powder, cinnamon, sweetener, and salt. Mix thoroughly until no lumps remain.
02 - Add milk, egg white, and vanilla extract to the dry mixture. Stir until a smooth, lump-free batter forms.
03 - In a small bowl, combine melted butter, brown sugar, and cinnamon until well blended.
04 - Drop spoonfuls of cinnamon swirl mixture onto the cake batter. Use a toothpick or knife to gently swirl through the batter, creating a marbled effect.
05 - Microwave on high for 60 to 90 seconds until the cake is set. The center should appear cooked yet remain moist; avoid overcooking.
06 - While the cake cools slightly, beat together cream cheese, milk, powdered sweetener, and vanilla until smooth and spreadable.
07 - Spread the cream cheese topping over the warm mug cake and serve immediately.

# Expert Tips:

01 -
  • It tastes like an indulgence but packs 20 grams of protein, so you're actually fueling your body, not just satisfying a sugar craving.
  • Seven minutes total means you can make this on a Tuesday morning without rearranging your entire day.
  • That cream cheese topping is tangy and rich enough that you won't miss a full-size pastry, and honestly, it's better warm.
02 -
  • Overcooking by even 15 seconds transforms this from moist and tender to rubbery and dense, so set a timer and actually check it at 60 seconds before committing to the full 90.
  • Softening your cream cheese beforehand isn't optional; cold cream cheese won't blend smoothly and you'll end up with lumpy frosting on an otherwise perfect cake.
03 -
  • Use a mug that's at least 10 ounces because this cake rises slightly during cooking and will overflow if your vessel is too small, which I learned the messy way.
  • The egg white is crucial for structure, so don't skip it or substitute with more milk, because you'll end up with cake-adjacent soup instead of actual cake.
