Mug cakes to the rescue when you need to have a bite of something sweet but don’t want to fuss with a whole cake. And this Banana-Chocolate Chip Mug Cake tastes just like banana bread but without taking forever to bake. In fact, this easy mug cake cooks in just 90 seconds!

The only trick to making mug cakes is starting with a big enough mug because these little cakes sure do puff up in the microwave! The egg, butter, and baking powder do their job, and the cake puffs up light and fluffy and oh-so-tasty! Avoid a mess in your microwave, and start with a big mug! More on that is below.

How To Make The Best Banana-Chocolate Chip Mug Cake

  1. Mix the all-purpose flour and baking powder in a small bowl.
  2. Mix the egg, melted butter, milk, and vanilla until smooth.
  3. Stir in the brown sugar and banana, then mix the wet ingredients with the dry.
  4. Fold in the chocolate chips and transfer the batter to a large buttered mug.
  5. Microwave on high for about 90 seconds or until the batter is cooked.
  6. Top with banana slices, whipped cream, or chocolate chips.
  7. Enjoy!

Chef Jenn’s Tips

  • Mash the banana with a fork. You’ll need about 1/2 a banana – save the rest to slice on top or pop the banana into the freezer to make smoothies!
  • Don’t overmix the batter – it will be lumpy from the banana, so don’t worry about the lumps!
  • The cake must rise while cooking if you want a light and fluffy cake, so make sure to butter the inside of the mug, so the cake doesn’t stick.
  • You can use dark chocolate, white chocolate, or whatever chocolate chips you have on hand.
  • Enjoy a serving of vegan drumsticks or lemon tuna pasta before your tasty dessert!

How Do You Know When A Mug Cake Is Done?

Mug cakes cook so quickly but telling if they’re cooked can be tricky! This is what I do:

  • Look for uncooked batter (the official name is goo) at the top of the cake. Touch it with your finger – if it is gooey, give the cake another 10-15 seconds in the microwave.
  • Insert a toothpick or slim knife into the middle of the cake and pull it out, checking for goo. A few clingy crumbs are OK, but uncooked batter means the cake needs a few more seconds.

    This was the perfect late-night treat! I used coconut sugar and it came out great. I plan on making it with white chocolate chips tomorrow!

    I’m not a big baker, so this was a perfect recipe for me. It came out exactly as I’d hoped – moist, tender, and sweet! I’ll be making this more often than I care to admit.
