Take one bite, and you'll be reminded of Thin Mint cookies, Andes mints, or mint chocolate chip cupcakes.

In Chicago where I live, we celebrate St. Patrick's Day large. There are parades, costumes, and we dye our river green!

You'll add green food coloring to the mint frosting recipe making them perfect for any St. Patrick's Day celebration.

Ingredients
- The cupcake batter uses vegetable oil to keep the cake extra moist.
- Lifeway Organic Plain Whole Milk Kefir adds moisture and a slight tang to the chocolate mint cupcakes.
- Peppermint extract is used in the batter and the chocolate mint buttercream to add that distinct mint flavor. The mint flavor in the cupcakes is subtle, so feel free to add extra peppermint extract in the batter if you want it to be more distinct.
- Cocoa powder is the only chocolate used in the cake batter, so make sure to use good quality, unsweetened cocoa powder for the best flavor.
- Baking powder and baking soda are used to make really fluffy cupcakes.
- I recommend using green gel food coloring in your frosting because it won't alter the consistency of your icing as much as a water based food coloring.
See recipe card below for a full list of ingredients and measurements.
Substitutions & Variations
- Place a mint Oreo or a Thin Mint in the bottom of the cupcake liners before adding the batter.
- Mix in chocolate chips or crushed Oreos to the mint chocolate cupcake batter.

How to Make Chocolate Mint Cupcakes
Step 1: Mix the sugar and vegetable oil in a medium bowl. Stir in the egg, plain whole milk kefir, and peppermint extract to combine.
Step 2: In a separate bowl, whisk flour, cocoa powder, baking powder, baking soda, and salt together.
Step 3: Stir the wet ingredients into the dry mixture, then mix in the hot water.
Step 4: Fill cupcake liners evenly with cake batter and bake at 350°F until a toothpick comes out clean.
Step 5: While the cupcakes cool, combine the butter, powdered sugar, peppermint extract, food coloring, and kefir until smooth.
Step 6: Pipe mint frosting onto fully cooled cupcakes. Add sprinkles or a chocolate drizzle if desired and enjoy!
Expert Baking Tips
- Make sure to use hot water in the batter because it helps activate the cocoa powder and bring out a rich, chocolatey flavor.
- I like to use paper cupcake liners to make it easy to remove the cupcakes from the pan and less messy to eat.
- Wait until your cupcakes are fully cooled before icing them or the frosting will melt off and make a big mess.
- I used an extra large closed star piping tip to pipe the mint frosting on top of the cupcakes.
Recipe FAQs
No. These cupcakes are super moist because of the vegetable oil in the batter.
Peppermint extract is pretty common and you can usually find it in the baking aisle by the vanilla extract. If not, you can easily find it online.
I would not recommend it because the flavor is a bit different. However, if you prefer mint over peppermint, feel free to try it!
