Packed with rich chocolate and peanut butter flavors, this mug cake recipe is so easy to prepare and is ready to eat in under 5 minutes!

Craving a bite of something sweet but don’t want to make a whole cake? Try a microwave mug cake!

The great thing about these microwavable treats is that you can make them with small amounts of ingredients you probably have on hand already. Big enough for one (or two, if you’re feeling generous!), these little cakes steam up in the microwave for quicker, more convenient baking.

They’re perfect for when you’re craving a little dessert or when you just want a little late-night snack! All you need is a few ingredients, a few minutes and a big ol’ coffee mug!

Best of all, no mixers, no sifters, no bowls! This single-serve mug cake is prepped and baked right in the mug.

The Perfect Mug Cake Mug

For this recipe, you’ll need a large 10 to 12 oz. mug. Make sure it’s microwave safe, too!

For best results, we suggest using a wide mug, if you can find one. This will help the cake bake evenly and may help prevent burning or over-cooking.

Also, make sure your mug doesn’t have any metal or metallic paint on it. A simple, ceramic mug works great!

Can You Make a Mug Cake in Advance?

This peanut butter chocolate mug cake should be eaten immediately; however, you can prep the ingredients and have them ready to go whenever you get the urge to bake.

If you want to prep your mug cake (or bring it with you to the office), simply combine your dry ingredients in your mug, then package your wet ingredients separately. Once you’re ready, add the wet ingredients to the dry and microwave away!

Other Add-In Ideas

  • Not a peanut butter fan? Try using milk chocolate, white chocolate or butterscotch chips instead.
  • You can also top your mug cake with chocolate hazelnut spread rather of whipped topping.
  • For added texture and flavor, try adding coconut, nuts, cinnamon or other candies to your cake.
