A soft, protein-rich mug cake with cinnamon swirls made from cottage cheese. Ready in minutes for a nutritious breakfast or snack.

# What You'll Need:

→ Wet Ingredients

01 - 1/3 cup cottage cheese, low-fat or full-fat
02 - 1 large egg
03 - 1 tablespoon milk of choice
04 - 1 teaspoon vanilla extract

→ Dry Ingredients

05 - 1/4 cup oat flour or finely ground rolled oats
06 - 1 scoop vanilla whey or plant-based protein powder
07 - 1/2 teaspoon baking powder
08 - 1/2 teaspoon ground cinnamon
09 - 1-2 tablespoons granulated sweetener of choice
10 - Pinch of salt

→ Cinnamon Swirl

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

→ Optional Cream Cheese Icing

14 - 1 tablespoon cream cheese, softened
15 - 1-2 teaspoons milk
16 - 1/2 teaspoon vanilla extract
17 - 1 teaspoon powdered sugar or sweetener

# How to Make It:

01 - Combine cottage cheese, egg, milk, and vanilla extract in a blender or food processor. Blend until completely smooth and creamy, approximately 30-45 seconds.
02 - In a 10-12 ounce 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 the dry ingredients. Stir thoroughly with a spoon until no dry pockets remain and batter is smooth.
04 - In a small bowl, mix melted butter, cinnamon, and brown sugar until combined. Drizzle this mixture over the batter in the mug, then gently swirl through with a knife or skewer to create a marble pattern.
05 - Microwave on high power for 1 minute 30 seconds to 2 minutes. The cake is done when it springs back lightly when touched and edges pull away slightly from the mug. Start checking at 90 seconds as microwave power varies.
06 - While cake cools slightly, combine softened cream cheese, milk, vanilla extract, and powdered sugar in a small bowl. Mix until smooth and drizzle-consistency.
07 - Drizzle icing over warm mug cake if desired. Serve immediately while warm for the best texture and flavor.

# Expert Suggestions:

01 -
  • You get 25 grams of protein without choking down another chalky shake
  • The texture is surprisingly fluffy, not dense or rubbery like some mug cakes
02 -
  • Overcooking by even 15 seconds turns this into a dry sponge so check early
  • The protein powder you choose changes the sweetness dramatically
03 -
  • Spray your mug with cooking spray even though it seems unnecessary
  • Use a 12 ounce mug or it might overflow in the microwave
