Step-by-Step
- Heat the oven to 350°F (177°C) and line a 12-cup muffin pan with paper liners.
- Whisk the flour, natural cocoa powder, baking soda, and salt together in a medium bowl.
- Beat the softened butter and granulated sugar for 2–3 minutes, until light and creamy. Beat in the egg and vanilla extract.
- In a separate bowl, stir together the buttermilk, liquid red food coloring, and distilled white vinegar.
- Add the dry ingredients to the butter mixture in alternating additions with the buttermilk mixture. Mix only until the batter is combined.
- Divide the batter evenly among the liners, filling each about two-thirds full. Bake for 18–20 minutes, until a toothpick inserted in the center comes out with only a few moist crumbs.
- Cool the cupcakes in the pan for about 5 minutes, then transfer them to a rack and cool completely.
- Beat the cream cheese and butter until smooth. Gradually add the sifted confectioners’ sugar, then beat in the vanilla and optional salt.
- Frost the cupcakes only after they are completely cool. Add red velvet crumbs, heart sprinkles, or another Valentine’s Day decoration if desired.
Notes
Use room-temperature butter, egg, buttermilk, and cream cheese for the best texture. Measure flour by weight when possible, or spoon it into a measuring cup and level it. Use natural cocoa powder rather than Dutch-process cocoa, and remove the cupcakes when the tester shows a few moist crumbs.
