08 - 1/2 tsp ground cinnamon
09 - 1–2 tbsp granulated sweetener of choice (e.g., coconut sugar, erythritol)
10 - Pinch of salt

11 - 1 tsp melted butter or coconut oil
12 - 1/2 tsp ground cinnamon
13 - 1 tsp brown sugar or sweetener

15 - 1–2 tsp milk
16 - 1/2 tsp vanilla extract
17 - 1 tsp powdered sugar or sweetener

# How-To Steps:

01 - Combine cottage cheese, egg, milk, and vanilla extract in a blender or food processor. Blend until completely smooth and creamy.
02 - In a 10–12 oz microwave-safe mug, whisk together oat flour, protein powder, baking powder, cinnamon, sweetener, and salt until evenly distributed.
03 - Pour the blended wet mixture into the mug with dry ingredients. Stir vigorously until fully combined and no dry pockets remain.
04 - In a small bowl, mix melted butter, cinnamon, and brown sugar until well combined.
05 - Drizzle or dollop the cinnamon mixture into the mug batter. Gently swirl with a knife or skewer to create marbled effect.
06 - Microwave on high power for 1 minute 30 seconds to 2 minutes, or until cake is set and springs back lightly to touch. Check at 90 seconds as microwave power varies.
07 - If using icing, whisk together softened cream cheese, milk, vanilla extract, and powdered sugar until smooth and drizzleable.
08 - Drizzle icing over warm mug cake and serve immediately for best texture.

# Expert Advice:

01 -
  • You get 25 grams of protein without drinking another chalky shake or eating plain cottage cheese
  • The entire process takes 7 minutes including the time it takes to find your blender
  • That cinnamon swirl creates pockets of gooey sweetness that make it feel like a real treat
02 -
  • Every microwave heats differently, so the first time you make this check at 90 seconds regardless of what the timer says
  • Protein powder affects the final texture significantly and some brands make the cake rubbery or dry, so stick to one you already trust
  • The cake will deflate slightly as it cools, which is completely normal and does not mean you did anything wrong
03 -
  • Spray your mug with a little coconut oil before adding ingredients for easier removal if you want to plate it
  • Let the cake rest for 60 seconds after microwaving to finish setting up before you add any frosting
