Funfetti Cupcakes

Ingredients

For the cupcakes

1 cup sugar

1 large egg, room temperature

1 stick unsalted butter, melted and cooled (approx. ½ cup)

1 tsp vanilla extract

¼ cup sour cream

1 ½ cups all-purpose flour

1 tsp baking powder

¼ tsp baking soda

Pinch salt (about ½ tsp)

½ cup milk

½ cup multicolored sprinkles

For the decorations

1 stick unsalted butter (about ½ cup), softened

2 cups confectioners’ sugar

2-3 tbsp milk

3 tbsps multicolored sprinkles

12-15 rainbow candy strips, cut into 3 inch pieces

Yields: 12 to 15 cupcakes

Directions:

Preheat oven to 350 degrees F.

Line a muffin tin with paper liners and set aside.

In a large bowl, cream together sugar and egg.

Add melted butter, vanilla and sour cream. Mix until all ingredients are well-incorporated.

In a separate bowl, whisk together all dry ingredients: flour, baking powder + soda and salt.

Slowly mix dry ingredients into wet ingredients, alternating with the milk. Mix with a spatula until all ingredients are well-incorporated, forming a cupcake batter.

Gently fold sprinkles into the batter.

Fill the lined muffin tin with cupcake batter, about 2/3 of the way.

Bake for 15 to 17 minutes. Allow to cool completely on a wire rack before decorating.

To decorate:

In a large bowl, use an electric mixer to beat together the softened butter, confectioners’ sugar and milk. The buttercream is ready once everything is smooth and forms semi-stiff peaks.
