- Sprinkle chocolate chips or chopped chocolate on top of the batter. Lightly press them in so they melt into the cake as it cooks.1 tablespoon dark chocolate chips
- Microwave on high power for 50–90 seconds, depending on your microwave’s wattage. Start with 50 seconds, check the center, and continue in 10-second bursts until the top is just set but still soft.
- Let the mug cake sit for a minute before digging in as it can be very hot. Enjoy as is, or top with extra chocolate chips, a drizzle of peanut butter, or fresh berries for added indulgence!

Notes
- Use a Microwave-Safe Mug: For best results, opt for a taller mug to prevent overflow. A smooth glazed mug makes cleaning the mug after cooking simple.
- Mix Dry ingredients and Wet Ingredients Separately: Ensure the baking powder and oat flour are evenly mixed before adding wet ingredients for the best texture.
- Microwave in Bursts: Cook on high power in 10-second bursts after the initial 1-minute cooking time if needed, to avoid overcooking.
- Enjoy Immediately: Mug cakes are best eaten fresh! Unlike traditional cakes that cool before serving, this single-serving cake is at its peak right after cooking. Even after 10 minutes, the soft and gooey texture can start to firm up, losing its light, tender bite.
