Instructions

Combine all the dry ingredients and mix until well combined.
Add in all wet ingredients and stir until everything is well incorporated. Ensure that it is well mixed with no dry pockets of flour at the bottom of the mug.
Microwave for 60 seconds, then check for doneness. Mug cake is done cooking when the top is mostly dry.
If it is undercooked, microwave at 10-second intervals. It should not take more than 90 seconds.
Let it rest for 1-2 minutes, and it is ready to be enjoyed!

Notes

*Sugar – Feel free to use sugar substitutes, such as erythritol, to make this chocolate protein mug cake low sugar. Can be omitted if your protein powder is on the sweeter side.

**Egg - Replace the egg with a chia egg (1 tablespoon chia seeds + 3 tablespoons water). Note that this will result in a slightly denser texture.

Helpful tips

Avoid overcooking – Overcooking can dry out your mug cake or make it rubbery. It’s perfectly fine if the center looks slightly undercooked; it will continue to cook from the residual heat.
Serve fresh – Mug cake tastes best fresh. If you have leftover cake, store it in an airtight container for up to 3 days. It is recommended to enjoy leftover cake cold, as reheating it might risk overcooking.
Topping ideas – I love topping it with chopped strawberries or banana slices for an extra boost of fiber and nutrients, but you could also try flaked sea salt, peanut butter, whipped cream, or even ice cream for a more indulgent treat.
