Method
Prep the oven and batter
- Preheat the oven to 375°F and line a muffin tin with cupcake liners.
- Whisk together all-purpose flour, baking powder, and salt in a mixing bowl.
- Cream butter and sugar until light and fluffy.
- Beat in eggs and vanilla extract until smooth.
- Alternately add the flour mixture and the combined sour cream and milk, mixing just until incorporated.
Fill and bake
- Fill each liner halfway with batter.
- Add 1 tsp dulce de leche to each muffin.
- Top each muffin with the remaining batter to cover the filling.
- Bake for 18–20 minutes, until golden and a toothpick comes out clean.
Coat and serve
- Mix cinnamon and sugar in a shallow bowl.
- While the muffins are still warm, brush each with melted butter.
- Roll the muffins in the cinnamon sugar mixture to coat.
- Serve warm.
Notes
For the clearest churro-style coating, coat immediately while muffins are warm so the butter grabs the cinnamon sugar. Store airtight in the fridge up to 3 days and rewarm in a 300°F oven for 5 minutes. Freeze up to 2 months (freeze uncoated or lightly coated), then thaw and re-coat by warming and rolling again. For a lighter option, use reduced-fat sour cream and butter.
