Ingredients
Method
- Preheat oven to 350°F (175°C). Whisk cake mix, eggs, melted butter, buttermilk, and 1 tsp vanilla until smooth, about 1 1/2 minutes on medium speed.
- Line a 12-cup muffin tin with paper liners and divide batter evenly, filling each 2/3 full.
- Bake for 18 to 20 minutes until a toothpick comes out with a few moist crumbs. Cool in the pan 5 minutes, then move to a wire rack to cool completely.
- Beat cream cheese and softened butter until smooth. Mix in 1 tsp vanilla, then gradually add powdered sugar, beating until fluffy.
- Pipe or spread frosting onto cooled cupcakes and serve.
Notes
If you only have low-fat buttermilk, it still works, but the crumb will be a little less tender. Let the cupcakes cool for at least 1 hour before frosting so the swirls stay firm.
