Ingredients

Protein Mug Cake

  • 1 Tbsp all-purpose flour, spooned & leveled 8g
  • 2 Tbsp granulated sugar 25g
  • 2 Tbsp unsweetened cocoa powder, sifted 10g
  • 1 scoop chocolate protein powder 30g
  • 1/4 tsp baking powder 1g
  • 1/8 tsp fine salt >1g
  • 1/4 cup water, room temperature 60g
  • 1 large egg white 30g
  • 1/2 tsp vanilla extract or vanilla bean paste 3g
  • 1 Tbsp milk or dark chocolate chips - optional 12g

Instructions

  • Whisk together 1 Tbsp flour, 2 Tbsp sugar, Tbsp cocoa powder, 1 scoop chocolate protein powder, 1/4 tsp baking powder, and a pinch of salt in a small bowl.
  • Add in 1/4 cup water, 1 large egg white, and 1/2 tsp vanilla. Stir together with a whisk together until smooth.
  • Pour into a 12 oz or larger microwave-safe mug and sprinkle 1 Tbsp of chocolate chips over the top of the batter if desired.
  • Heat for 50-60 seconds then check the doneness. If the batter is still liquid in the center, heat for an additional 5-10 seconds then check it again. Repeat until your mug cake is cooked through the center. I personally like it to still be gooey on the sides!
  • Let the cake cool for a couple minutes (or else you will burn your tongue - trust me!!), then top with your favorite toppings and enjoy warm! Peanut butter, whipped cream, or chocolate sauce all work great as a topping.

Notes

Tips for Making the Best Protein Mug Cake

  • Make sure you use a large enough mug or glass, and that it is microwave safe (metal-free). As long as your mug has a capacity of 12 oz. or 1 1/2 cups or more you're good to go.
  • Cook time can vary based on your microwave! Different microwaves have different wattage, and can vary from 600-1200 watts. The higher the watts the faster your mug cake will cook. My microwave cooks at 1200 watts.
  • Any type of chocolate protein powder should work! I used whey protein but vegan or other types of protein powder work too.
  • Top your mug cake with whipped cream, peanut butter, and / or chocolate syrup to make it even more delicious.
  • Please see the section above for substitutions and ingredients swaps.
