Ingredients:
For the Cupcakes:
4 tablespoons unsalted butter, at room temperature
¾ cup granulated sugar
1 egg
2½ tablespoons unsweetened cocoa powder
3 tablespoons red food coloring
½ teaspoon vanilla extract
½ cup buttermilk
1 cup + 2 tablespoons all-purpose flour
½ teaspoon salt
½ teaspoon baking soda
1½ teaspoons distilled white vinegar
For the Cream Cheese Frosting:
4 ounces butter, at room temperature
4 ounces cream cheese, at room temperature
2½ cups powdered sugar
1 tablespoon vanilla extract
Directions:
1. Preheat oven to 350 degrees F. Line a standard muffin/cupcake pan with liners.
2. On medium-high speed, cream the butter and sugar until light and
fluffy, about 3 minutes. Turn the mixer to high and add the egg. Scrape
down the bowl and beat until well incorporated.
3. In a separate small bowl, mix together the cocoa powder, vanilla
extract and red food coloring to make a thick paste. Add to the batter
and mix on medium speed until completely combined. You may need to stop
the mixer to scrape the bottom of the bowl, making sure that all the
batter gets color.
4. Reduce the mixer speed to low and slowly add half of the
buttermilk. Add half of the flour and mix until combined. Scrape the
bowl and repeat the process with the remaining milk and flour. Beat on
high until smooth.
5. Again, reduce the mixer speed to low and add the salt, baking soda
and vinegar. Turn to high and beat for another couple of minutes until
completely combined and smooth.
6. Divide the batter evenly between the cupcake liners and bake for
about 20 minutes, or until a thin knife or skewer inserted into the
center of the largest cupcake comes out clean.
7. Cool for 10 minutes and then remove cupcakes from the pan and
place them on a cooling rack to cool completely before frosting.
8.
To make the frosting:
Using the whisk attachment, whip the butter and cream cheese on high
speed for about 5 minutes, scraping the bowl down as necessary. Reduce
the speed to low and slowly add the powdered sugar until all is
incorporated. Add the vanilla and mix to combine. Increase the speed to
medium high and whip for a few minutes until the frosting is light and
fluffy, scraping the bowl as necessary.
