Equipment
Method
Preheat and prep
- Preheat the oven to 375°F and line a muffin tin with cupcake liners.
- Whisk together all-purpose flour, baking powder, and salt.
Make the batter
- Cream butter, softened and sugar until light and fluffy.
- Beat in eggs and vanilla extract.
- Alternately add the flour mixture and the combined sour cream and milk until just mixed.
Fill and bake
- Fill each liner halfway with batter.
- Add 1 tsp dulce de leche to each muffin.
- Top with the remaining batter.
- Bake at 375°F for 18-20 minutes, until golden and a toothpick comes out clean.
Coat in cinnamon sugar
- Mix cinnamon and sugar in a shallow bowl.
- While muffins are still warm, brush each with melted butter, then roll in cinnamon sugar mixture.
- Serve warm.
Notes
Pro tip: coat the muffins right after baking while they’re warm so the butter helps the cinnamon sugar cling and sparkle. Store leftovers in an airtight container in the refrigerator up to 3 days; rewarm briefly before serving. Freezer: yes—freeze in a sealed bag up to 2 months and thaw overnight in the fridge. For a dairy-light option, substitute milk and sour cream with unsweetened lactose-free versions.
