Method
Make the cupcake batter
- Whisk together the all-purpose flour, baking powder, and salt until evenly combined.
- Beat the softened butter with the granulated sugar until light and fluffy.
- Add the eggs one at a time, beating well after each addition.
- Alternate adding the flour mixture and sour cream, beginning and ending with the flour mixture.
- Stir in the vanilla extract and whole milk until the batter is smooth.
Bake
- Fill cupcake liners with batter and bake at 350°F for 18 minutes, until a toothpick comes out clean.
- Cool the cupcakes completely before frosting.
Make the frosting and assemble
- Beat the softened butter with the powdered sugar until fluffy.
- Mix the cinnamon with the granulated sugar for the coating.
- Pipe frosting onto the cooled cupcakes and roll the frosted top in the cinnamon sugar.
- Top each cupcake with a churro stick.
- Drizzle with melted dark chocolate if desired and serve.
Notes
Pro tip: for clean frosting rolls, frost only the tops right before coating so the cinnamon sugar adheres. Store cupcakes covered in the fridge up to 3 days; bring to room temperature before serving. Freeze unfrosted cupcakes up to 2 months—thaw, then make frosting and assemble. For a lighter option, swap half the butter in the cupcakes for an equal amount of neutral oil or use a reduced-fat sour cream (texture will be slightly softer).
