Equipment

10-12 ounce microwave-safe mug or ramekin

Ingredients

3 tablespoons oat flour
2 tablespoons chocolate protein powder
1 tablespoon unsweetened cacao powder
½ teaspoon baking powder
pinch of sea salt
1 ½ teaspoons maple syrup
¼ cup unsweetened milk your choice plant based or dairy
2 tablespoons chocolate chunks divided use

Instructions

Use a 10- to 12-ounce microwave-safe mug or ramekin to allow room for the cake to rise while cooking. Add the oat flour, chocolate protein powder, cacao powder, baking powder, and salt, and whisk until evenly combined.
Add the maple syrup, oat milk, and half of the chocolate chunks. Stir until a smooth batter forms. Sprinkle the remaining chocolate chunks over the top.
Microwave on High for 60 seconds.
Continue cooking in 10-second intervals until the cake is puffed and the top looks set but still slightly soft in the center. Total cook time is usually 80 to 90 seconds depending on your microwave.
Allow the mug cake to cool for 1 minute before serving.
Top with whipped cream, nut butter, or a small scoop of ice cream if desired.

Notes

• Every protein powder bakes differently and may absorb more or less liquid.
• If the batter seems very thick, add 1 to 2 teaspoons additional oat milk.
• Use a large mug to prevent overflow during cooking.
• Microwave times vary; start checking after 60 seconds.
