Peppermint Swirl Mug Cake

This mug cake tastes just like a peppermint candy and has swirls of red mixed in, making it very festive.

I had another post planned for today, but it didn’t quite turn out. It was one of those days where nothing is going right in the kitchen and you just have to step away. I managed to somewhat salvage my kitchen disasters by making this simple holiday mug cake, but it actually took three attempts even though this isn’t a new recipe. It’s actually a recipe I created last year that ended up not making the final cut for my new book*.

The first try, I had too much red and the entire batter became red. The second time, I forgot to add the baking powder and it was just a dense mess. Finally, on the third try, I got a decent result.

This cake is a little plain on its own because it just tastes like mint, so I highly recommend some Cool Whip or whipped cream frosting. I really wanted you to see the swirls, so I kept it plain for these photos.

As I mentioned above, this cake actually did not make the cut for my 5 Minute Mug Cake book because it is a little plain on its own. But it looks so festive for this time of year that I really wanted to share it.

I do have nearly 100 other delicious mug cake recipes in my new book*.

Prep Time: 1 minute
Cook Time: 4 minutes
Total Time: 5 minutes
Course: Dessert
Cuisine: American
This mug cake tastes just like a peppermint candy and has swirls of red mixed in, making it very festive.


  • 4 tbsp all-purpose flour
  • 1/4 tsp baking powder
  • 1/2 tbsp vegetable oil
  • 3 tbsp fat free milk
  • tsp granulated sugar
  • 1/4 tsp peppermint extract
  • 1/4 tsp vanilla extract

Optional Toppings

  • Cool Whip
  • whipped cream frosting
  • chocolate drizzle


  • Add all ingredients except food coloring into an oversized microwave safe mug. Mix with a whisk until batter is smooth. Add in one drop of food coloring. Using a fork, gently swirl in a circular clockwise motion until red swirls form, but stopping before cake batter turns completely red.
  • Cook in the microwave for about 1 minute or until done. The cake is a bit plain, so I recommend that you serve it with whipped cream, Cool Whip, or a chocolate drizzle.

    It is absolute heaven if the hot chocolate mug cake is paired with a peppermint swirl mug cake. I was looking through your mug cakes, when I saw both. I couldn’t decide, so I said “why not make both?”. I made the peppermint cake in the mug, and the hot chocolate one in a bowl(I cute the recipe in half for each.… too much mug cake is a thing). Then, I used a little spatula to spoon all of the hot chocolate into the mug. It landed perfectly in the middle! I didn’t add marshmallows though. Also, I didn’t have peppermint extract, I took four (this was for a half recipe), put them in a ziplock,  and crushed them with the meat hammer thingy.  Then I just mixed them in. It tasted minty with them too…. Much better than buying extract. When baked, the hot chocolate had risen a little more, and it looked so cool. This was absolutely delicious! 

    • so glad you enjoyed it! I’ve actually been thinking of making a hot choc peppermint! I made the drink not long ago and was thinking it would work so well as a mug cake!

  2. Cuteness! I love the swirl. Might be fun with whipped cream and chopped candy canes on top.

  3. That sounds perfect! Love the red swirls, so cute 🙂
