03 - 1 teaspoon baking powder
04 - 1/2 teaspoon baking soda
05 - 1/4 teaspoon salt

14 - 3 cups powdered sugar, sifted
15 - 2 tablespoons whole milk
16 - 1/2 teaspoon peppermint extract
17 - Red gel food coloring (optional)

→ Decoration

18 - 2 tablespoons crushed peppermint candies or candy canes

# How-To Steps:

01 - Preheat oven to 350°F. Line a 12-cup muffin tin with paper liners.
02 - Whisk together the flour, cocoa powder, baking powder, baking soda, and salt in a medium bowl.
03 - In a large bowl, cream the unsalted butter and granulated sugar until light and fluffy. Add eggs one at a time, mixing well after each addition. Stir in vanilla and peppermint extracts.
04 - Add the dry ingredients to the creamed mixture in three parts, alternating with milk and sour cream, starting and ending with the dry ingredients. Mix until just combined.
05 - Divide the batter evenly among the cupcake liners.
06 - Drag a toothpick through each filled liner to create a marbled peppermint swirl pattern.
07 - Bake for 18 to 20 minutes, or until a toothpick inserted into the center comes out clean. Cool on a wire rack.
08 - Beat softened butter until creamy. Gradually add powdered sugar, milk, and peppermint extract. Continue beating until light and fluffy.
09 - Optionally add a few drops of red gel food coloring and gently swirl with a spatula without overmixing to create a festive appearance.
10 - Pipe the frosting onto cooled cupcakes and sprinkle with crushed peppermint candies.

# Expert Tips:

01 -
  • The contrast between deep chocolate and refreshing peppermint feels like a flavor surprise every single time you bite into one.
  • They come together in less than an hour, and the swirl technique looks far more impressive than the actual effort required.
  • The frosting is cloud-soft and pipes beautifully, making these feel like a bakery-worthy treat you made in your own kitchen.
02 -
  • Room temperature ingredients make all the difference in the texture; cold eggs and butter create lumps that won't smooth out no matter how long you mix.
  • Don't skip the cooling step or your frosting will slide right off, and resist the urge to frost warm cupcakes even when you're impatient.
  • The peppermint extract is powerful, so taste as you go when adding it to the frosting, because more is genuinely not always better.
03 -
  • Measure your flour by spooning it into a measuring cup and leveling it off, not by scooping straight from the bag, because that compacts the flour and changes your ratios.
  • Keep your peppermint extract in a cool, dark place, and buy the real thing whenever possible, because it makes a tangible difference in the final flavor.
  • If you don't have a piping bag, a small spoon or zip-top bag with a tiny corner snipped off works perfectly fine for frosting cupcakes.
