Ingredients
Coffee Cake Mug Cake
- 3 Tbsp vanilla protein powder
- 1 Tbsp oat flour or all purpose flour
- 1 Tbsp brown sugar
- 1/4 tsp baking powder **see note
- pinch salt
- 3 Tbsp milk
- 1 Tbsp melted butter
- 1/2 tsp vanilla
- 1/2 tsp cinnamon
Streusel
- 1 tsp butter
- 1 Tbsp oat flour
- 1 tsp brown sugar
- pinch cinnamon optional
Instructions
- In a microwave-safe mug, combine the protein powder, oat flour, brown sugar, baking powder, salt, and cinnamon. Stir until dry ingredients are evenly mixed.
- Melt just one tablespoon of butter, but keep 1 teaspoon solid butter for the streusel
- Add the milk, melted butter or coconut oil, and vanilla extract. Stir until the batter is smooth and lump free, scraping the sides of the mug.
- Make the streusel by mixing a teaspoon of butter, oat flour, brown sugar, and cinnamon in a small bowl until crumbly. You can use a small fork or your fingers for best results.
- Microwave your mug cake about halfway (25-30 seconds)
- Sprinkle the streusel evenly over the top of the batter in the mug.
- Microwave until done, which should be another 25-30 seconds. Stop at 25 seconds and start checking. I usually add 10 seconds at a time after that until it’s done, but if your microwave is particularly strong, I would recommend an extra 5 seconds at a time.
- Let the mug cake cool for 1 to 2 minutes to cool and enjoy fresh of out the mug.
