A mug cake with protein powder is a single-serve protein cake baked in the microwave for 90 seconds. It’s a quick and healthy way to fix a cake craving in the morning after a workout or in the afternoon.
In a microwave-safe tall mug of at least 250 ml (1 cup) volume, stir all the dry ingredients until well combined and no lumps of protein powder show.
Stir in the milk until the batter is smooth, slightly thick, but still liquid, like a chocolate cake batter.
Microwave in the center of the microwave at 900W for 90 seconds or stop after the cake rises in the mug .
Keep microwaving by extra 10-second bursts until the center is set, not gooey or liquid. Wait 30 seconds or so before eating as the mug cake is very hot.
Sprinkle dark chocolate chips on top if you like . They melt on top of the hot cake in the mug and taste delicious.
