Method
Mix and bake the cupcakes
- Whisk the all-purpose flour, baking powder, and salt together in a bowl 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 to the batter, beginning and ending with the flour mixture.
- Stir in the vanilla extract and whole milk just until the batter is smooth.
- Fill cupcake liners and bake at 350°F for 18 minutes, until a toothpick comes out clean.
- Cool the cupcakes completely before frosting.
Frost, coat, and finish
- Beat the softened butter for frosting with the powdered sugar until fluffy.
- Mix the cinnamon with the granulated sugar for coating.
- Pipe the frosting onto the cooled cupcakes, then roll the frosted tops in the cinnamon sugar.
- Top each cupcake with a churro stick or churro piece.
- Drizzle with melted dark chocolate if desired and serve.
Notes
For the cleanest cinnamon-sugar coating, frost and roll immediately while the frosting is fresh. Store cupcakes in an airtight container in the refrigerator for up to 3 days; freeze unfrosted cupcakes up to 2 months and thaw before frosting. For a lighter option, substitute half the butter in the cupcake batter with neutral oil (same volume) to reduce saturated fat while keeping the crumb tender.
