Mug Cake

  • 1/3 cup oats (old fashioned or quick)*
  • 1 scoop XTEND PRO Cookie Butter flavored protein powder
  • 1 whole egg
  • 1/4 cup nonfat Greek yogurt
  • 2 tbsp milk
  • 1/2 tsp baking powder
  • Cinnamon to taste
  • Pinch of salt


  • 1 tbsp cookie butter (melted to make it easier to drizzle)
  • 1 tbsp raspberry jam (or flavor of choice)
  • 1-2 crushed Biscoff cookies (optional)


*You can also just use 1/4 cup pre-ground oat flour, or whole wheat flour.


  1. Add all mug cake ingredients to a blender. Blend until a smooth batter is formed. Alternatively, you can grind the oats into a flour first, then mix in a bowl like you would any other batter.
  2. Spray a large, microwave safe mug with nonstick spray. Pour batter into mug. Microwave for 1 minute.
  3. Continue to microwave for 15 second intervals until done. It is best to leave it a little underdone to keep from drying out. Mine was done after about 1 minute and 30 seconds.
  4. Once cooked, drizzle melted cookie butter over the mug cake. Top with jam, crushed cookies, and enjoy!
