Serving Size 1 Brownie

Equipment

  • 1 microwave
  • 1 mug or ramekin

Ingredients

  • 2 tbsp sunflower seed butter , or any nut butter like peanut butter, cashew butter, almond butter, etc.
  • 1 tbsp maple syrup
  • 1 tbsp high protein yogurt – Greek sheep or vegan for dairy free. You could also use cottage cheese here.
  • 1 tbsp unsweetened cocoa powder
  • 2 tbsp chocolate protein powder I used a grass-fed Beef Protein Powder but use your favorite. Use a plant-based one to keep the recipe vegan.
  • 1 tbsp coconut or almond flour
  • 2 tbsp coconut milk or milk of choice
  • ¼ tsp baking powder
  • Pinch of sea salt
  • 1 tbsp Mini chocolate chips or chopped dark chocolate

Instructions

  • In a microwave-safe mug or ramekin, stir together the sunflower or nut butter, maple syrup, and yogurt until smooth. Add in the cocoa powder, chocolate protein powder, flour, baking powder, and salt. Mix well. Stir in the coconut milk until the batter is smooth and thick. The batter should be thick but spreadable. If it seems too thick (protein powders vary quite a bit), add an extra teaspoon or two of milk. Fold in the chocolate chips or chunks.

Notes

Recipe Tip: For a super fudgy brownie mug cake, don’t overcook it in the microwave. Start with 45-60 seconds, then check. It should be set around the edges but slightly gooey in the center. The residual heat will finish cooking it without drying it out.
Pro Tips to Get It Extra Fudgy
  • Don’t overmix—just until combined.
  • Add a square of dark chocolate to the center before microwaving for a melty lava effect.
