Instructions
- Preheat your oven to 350°F (175°C) and line a muffin tin with cupcake liners.
- In a mixing bowl, whisk together flour, baking powder, baking soda, and salt. Set aside.
- In a stand mixer bowl, beat the unsalted butter and light brown sugar until light and fluffy.
- Add in eggs one at a time, mixing well after each addition.
- To the butter-sugar mix, stir in sour cream, vegetable oil, vanilla extract, and milk until combined.
- Gradually add the dry ingredients into the wet mixture and mix until just combined; avoid overmixing.
- Spoon batter into each cupcake liner about two-thirds full. Add about one teaspoon of dulce de leche into the center of each cupcake batter.
- Bake for about 15 minutes or until a toothpick comes out clean when inserted into the center.

- Once cooled completely, frost each cupcake generously with the prepared buttercream using a piping bag or spatula.
