• Preheat oven to 350°F. Line your cupcake pan with cupcake liners.
• Mix together, either by hand or in a stand mixer, the oil, vanilla, sour cream, heavy cream, and eggs. Then mix in the boxed cake mix and M&Ms.
  1 box of white cake mix, ½ cup vegetable oil, 2 tbs vanilla, ¾ cup sour cream, ¾ cup heavy cream, 4 egg whites, ¾ cup M&Ms
• Scoop the batter into your cupcake liners ¾ full. I like using a measuring cup.
• Bake for 14 minutes or until a toothpick inserted comes out clean.
• Let the cupcakes cool completely before frosting.

Red White and Blue Frosting

• In a stand mixer, whip your butter on medium-high speed until the butter is light and fluffy. Then mix in the vanilla and salt.
  2 cups Unsalted Butter, ½ teaspoon salt, 2 tbs vanilla
• Alternating between 1 cup powdered sugar and 1 tablespoon heavy cream, mix each in until fully incorporated. I recommend mixing this on medium-low, then once all the heavy cream and powdered sugar are added, turn the mixer on medium/high and whip for 30 seconds to add volume.
  10 tbs heavy cream, 10 cups powdered sugar
• Divide the frosting into three separate bowls. Fold in red food coloring to one bowl, blue to another, and leave the third white.
  1 teaspoon Red Food Coloring, ½ teaspoon Blue Food Coloring
• Place your piping tips in the piping bags (or cut the corner off a piping bag*), then add each color frosting to its own bag. Pipe on the frosting in a circle, then repeat with the other colors. I like to alternate the colors, then add sprinkles and stars.
