Ingredients

Scale
  • 1 ¾ cups all-purpose flour (220 g)
  • 1 cup granulated sugar (200 g)
  • 1 ½ tsp baking powder
  • ¼ tsp salt
  • ½ cup unsalted butter, softened (113 g)
  • 2 large eggs, room temperature
  • ¾ cup whole milk (180 ml)
  • ¼ cup sour cream (60 ml)
  • 1 tsp pure mint extract
  • 1 tsp vanilla extract
  • Green food coloring (optional, a few drops)
  • For the Mint Buttercream Frosting:
  • 1 cup unsalted butter, softened (227 g)
  • 4 cups powdered sugar, sifted (480 g)
  • 2–3 tbsp heavy cream or whole milk (30–45 ml)
  • 1 tsp mint extract
  • ½ tsp vanilla extract
  • Pinch of salt
  • Green food coloring (optional)

Instructions

  1. Preheat oven to 350°F (175°C) and line a 12-cup muffin tin with cupcake liners.
  2. In a large bowl, whisk together flour, sugar, baking powder, and salt.
  3. Using a mixer, beat softened butter until creamy, about 2 minutes. Add eggs one at a time, mixing well after each addition, about 3 minutes total.
  4. In a separate bowl, combine milk, sour cream, mint extract, vanilla extract, and green food coloring if using.
  5. Gradually add the wet mixture to the butter-egg mixture, mixing on low speed.
  6. Slowly add dry ingredients to wet ingredients, mixing until just combined. Do not overmix.
  7. Fill cupcake liners about two-thirds full with batter.
  8. Bake for 18-22 minutes, checking at 18 minutes with a toothpick for doneness.
  9. Cool cupcakes in the tin for 5 minutes, then transfer to a cooling rack to cool completely, about 30 minutes.
  10. For frosting, beat softened butter until fluffy (3-4 minutes). Gradually add sifted powdered sugar, alternating with heavy cream or milk until spreadable.
  11. Mix in mint extract, vanilla, salt, and green food coloring until color is even.
  12. Frost cooled cupcakes generously using a piping bag or spatula. Optionally, sprinkle with mini chocolate chips or crushed peppermint candies.

Notes

Use room temperature ingredients for best results. Start with less mint extract and adjust to taste. Do not overmix batter to avoid tough cupcakes. Cool cupcakes completely before frosting to prevent melting. For dairy-free or gluten-free versions, substitute ingredients accordingly but expect texture changes.
