Have you jumped on the mug cake bandwagon? I was a skeptic at first, until I made my first mug cake. A warm and gooey cake, mixed in a mug, made in the microwave and ready in 90 seconds?! Could it really be true?
The first mug cake I made was a simple vanilla cake and my kids happily scooped it out of my hands. I quickly came up with other varieties of mug cakes but only shared my pumpkin spice mug cake on the blog. Today I’m sharing our newest favorite flavor, a peppermint chocolate mug cake – just in time for the holidays!

Ingredients you need

- Unsweetened cocoa powder: You can use regular or dark cocoa powder.
- Milk: You can use regular milk or non-dairy milk.
- Extra virgin olive oil: I bake exclusively with olive oil. Choose a mild flavored oil, not a peppery one. You can also use any other neutral vegetable oil.
- Chocolate chips: Depending on personal preference you can use semi-sweet, milk or even dark chocolate. I have also used non-dairy vegan chocolate chips from Enjoy Life.
- Peppermint candies: Instead of using peppermint extract, I crush a peppermint and add it to the mug cake.
- Pantry staples: All purpose flour, granulated sugar, baking powder and salt.
Step-by-step directions
- Mix dry ingredients. Add flour, sugar, cocoa powder, baking powder, and salt into a 12-ounce microwave-safe mug.
- Add wet ingredients. Stir with a fork until mixed, then stir in milk and oil.
- Add chocolate chips. Stir in chocolate chips and crushed peppermint candies. If mug is filled more than half with batter, your mug is too small and the batter will overflow in the microwave.
- Microwave cake. Use a damp paper towel to wipe excess off the sides of the mug. Microwave for 90 seconds, then let the cake stand for 1-2 minutes before eating.
How can I make mug cake mix gifts?
I have made a dozen different versions of this peppermint chocolate mug cake to come up with an easy chocolate mug cake mix you can pack up and gift. The only addition your recipient will need to add is water and oil to make this at home or at work.

The key is milk powder. I have used three different powdered milk varieties and they all work well in this mix, including a vegan option. Substitute the milk in the recipe for either ONE of the following:
- 4 tablespoon water and 4 tablespoons Coffee Mate nondairy creamer
- 4 tablespoon water and 2 teaspoon powdered non-fat milk (Bob’s Red Mill brand)
- 4 tablespoon water and 2 tablespoons coconut milk powder (Native Forest brand)
Just add your preferred milk powder to the cake mix bags. To get the layered effect, I added the ingredients in the following order:
- sugar and salt
- flour and baking powder
- milk powder
- cocoa powder
- chocolate chips
- crushed peppermints
I made these cute gift tags you can print out to make your own peppermint chocolate mug cake mix gift bags. Pop a couple in a pretty mug, maybe a cute spoon, too, and you have a fabulous teacher or Secret Santa gift.

Storing Instructions
TO STORE: Mug cakes are meant to be eaten right away. If you do have any leftovers, you can cover it and refrigerate for up to 4 days. The powder mixes should last for 6 months to a year, if sealed and stored in a cool dark place.
Yes! I include exact measurements and a free printable label so you can prep these as cute edible gifts for the holidays or special occasions.
Most often, it’s due to overcooking. Microwave ovens vary, so start with 90 seconds and adjust by 10-second intervals. Also, avoid overmixing the batter.
Use a microwave-safe mug that holds at least 10–12 ounces to prevent overflow. Avoid mugs with metallic details or very thin walls.
