What Makes This Recipe So Good

Remember Easy Bake Ovens? This is kind of like a grown-up version of that… only way better. In less than 5 minutes you’ll go from ingredients to gluten-free chocolate cake, with minimal effort.
The single-serve portion size is so convenient for anyone living alone or just watching what they eat. You won’t be tempted to eat 2 or 3 cupcakes or a slice of cake as big as your head since you’re only making one mini-cake at a time.
This recipe is egg-free, which means it won’t have a rubbery texture when you microwave the batter. Instead, it’ll be moist and light and melt-in-your-mouth good!

Chef’s Tips

The cake will rise and expand as it “bakes” in the microwave. If your mug is on the small side, put a paper towel or a dish underneath it in the microwave, to catch any overflow.
You can make this mug cake in the oven if you prefer not to use a microwave. Just be sure to use an oven-safe mug! Place the mug on a baking sheet, then bake your cake for 15-20 minutes at 350° Fahrenheit.
To cut down on clean-up, you can mix all of the ingredients directly in the coffee mug. I think it’s a little easier to mix them in a bowl and pour them into the mug, but do what works for you!

Equipment

medium mixing bowl see Notes
whisk
flour sifter optional, see Notes
microwave-safe coffee mug 8-ounce or 12-ounce mug
Microwave
toothpick or butter knife

Instructions

Add 2 tablespoons neutral-flavored oil, 5 tablespoons milk of choice, and 1 teaspoon pure vanilla extract to medium mixing bowl. Whisk ingredients are fully combined.
Sift ¼ level cup gluten-free all-purpose flour, 2 tablespoons granulated white sugar, 3 tablespoons baking cocoa powder, ⅛ teaspoon fresh baking soda, and ⅛ teaspoon salt into mixing bowl with wet ingredients. Whisk vigorously until ingredients are fully incorporated, forming smooth batter.
Transfer batter mixture into microwave-safe mug and top batter with 2 tablespoons chocolate chips if desired.
Place mug in microwave and microwave 60 seconds at full power. After 60 seconds, check doneness of cake. Insert toothpick or butter knife into center of cake, then immediately remove toothpick (or knife) and check for crumbs. If toothpick (or knife) is covered with wet batter or large amount of moist crumbs, return mug to microwave and microwave 10 seconds more. Repeat as needed until toothpick comes out of cake with very few or no crumbs.
Once mug cake is fully "baked", remove mug from microwave and let cool slightly. Enjoy mug cake warm or at room temperature.

Notes

Mixing Bowl: For less clean-up, you can mix the ingredients together right in your mug, instead of using a separate bowl. I just personally find it’s easier to make sure everything’s fully incorporated in the mixing bowl.
Flour Sifter: Totally optional – if you don’t have one or don’t want to use it, don’t give it a second thought. Just make sure to break up any clumps or lumps in your dry ingredients before adding them to the wet ingredients so your ingredients mix completely!
Flour: We used King Arthur’s Gluten-Free Measure-for-Measure Flour which contains xanthan gum.
Xanthan Gum: If your all-purpose gluten-free flour doesn’t include xanthan gum, you do need to add some in separately. Your cake won’t have the right texture if you don’t use xanthan gum. For a recipe this small, you should only need a dash.
Bake Time: Every microwave is different. Our cake was ready after 60 seconds, but you may need additional time. Be careful not to microwave it too much or your cake will be very dry.
Make it Dairy Free: Use almond milk or coconut milk, and use dairy-free or vegan chocolate chips.
Make it Vegan: Use almond milk or coconut milk, and use vegan chocolate chips. Make sure your granulated sugar is 100% vegan and not filtered with bone char.
Make it Keto: Check out our keto mug brownie recipe!
