This gluten-free mug cake is rich, moist, and full of chocolatey flavor. Made with oat flour, it's incredibly quick and easy to whip up when a dessert craving strikes!
In a bowl, mash the banana well, then combine it with peanut butter, plant milk, and vanilla extract.
Add in the oat flour, cacao powder, brown sugar, baking soda, and salt, stirring until well combined. Fold in the chocolate chips.
Transfer the batter to a heat-safe mug. Sprinkle the top with extra vegan chocolate chips and microwave for 2-3 minutes, or until the center is just set.
Alternatively, bake it in an oven at 350°F for 15-20 minutes, or until a toothpick inserted into the center comes out fairly clean.
Serve immediately with extra chocolate chips, peanut butter, icing, or ice cream on top. Happy eating!
Notes
Cut down the cleanup: We think it's easier to combine all of the ingredients before adding them to the mug, but you can feel free to combine everything in a single cup for quicker cleanup.
Adjust the cooking time: Every microwave and oven cooks differently. Be sure to check on your mug cake as it bakes, and adjust the time as needed.
Expect it to sink: As mug cakes cook, they expand and rise in the microwave like a souffle. Once they begin to cool, they tend to deflate and sink a bit in the center, but this doesn't affect the flavor at all!
Use an appropriatelysized mug: For the best results, fill your mug 3/4 of the way up. If you have extra batter, use another mug or ramekin to prevent overflows.
