2 tablespoons vegetable oil
6 tablespoons unsalted butter softened
1/2 cup granulated sugar
1/2 cup light brown sugar packed
2 large eggs
2 teaspoons vanilla extract
1 cup all-purpose flour
6 tablespoons unsweetened cocoa powder
1/2 teaspoon baking soda
1/4 teaspoon baking powder
1/4 teaspoon salt
3/4 cup milk
For the frosting
1 cup unsalted butter soft
3 cups confectioners’ sugar
2 tablespoons heavy cream
1/2 teaspoon peppermint extract
3-4 drops green food coloring
chocolate mint candies optional
- Preheat the oven to 350ºF. Line 20 muffin cups with paper liners. Set aside.
- In a large bowl, beat together the oil, butter, and sugars until fluffy. Add the eggs one at a time beating well after each addition. Beat in the vanilla.
- In a separate bowl, combine the flour, cocoa powder, baking soda, baking powder, and salt. Stir with a whisk. Gradually add the flour mixture to the butter mixture alternating with the milk, begin and end with the flour mixture. Beat until well blended.
- Spoon 2 tablespoons of batter into the paper lined muffin pans. Bake for 15-20 minutes or until a wooden toothpick inserted into the center comes out with only a few dry crumbs. Remove cupcakes immediately from pans, and cool completely on a wire rack.
Make the frosting
