Ingredients

Vanilla Cupcakes

  • ½ cup whole milk
  • ½ cup vegetable oil
  • 2 large eggs
  • 2 teaspoons pure vanilla extract
  • 1 cup granulated sugar
  • 1 ½ cups all purpose flour regular or gluten-free measure-for-measure flour blend
  • 1 teaspoon baking powder

Berry Filling

  • ½ cup raspberries rinsed and patted dry
  • ½ cup blueberries rinsed and patted dry
  • ½ cup diced strawberries
  • 1 tablespoon lemon juice
  • 1 teaspoon cornstarch

Vanilla Mascarpone Frosting

  • 6 tablespoons unsalted butter softened
  • 4 ounces mascarpone cheese softened
  • 2 ½ cups powdered sugar sifted if any lumps
  • 1 teaspoon pure vanilla extract

Instructions

Vanilla Cupcakes

  • Preheat the oven to 350F and line 12 muffin cavities with paper baking liners.
  • In a large bowl, whisk together the milk, vegetable oil, eggs, and vanilla extract.
    ½ cup whole milk, ½ cup vegetable oil, 2 large eggs, 2 teaspoons pure vanilla extract
  • Add the sugar and whisk to combine.
    1 cup granulated sugar
  • Add the flour and baking powder. Whisk just until combined— don’t overmix!
    1 ½ cups all purpose flour, 1 teaspoon baking powder
  • Divide the batter evenly between the prepared muffin cavities, filling each one with ¼ cup of batter.
  • Bake for 16-18 minutes, or until a toothpick inserted into the center of a cupcake comes out clean.
  • Transfer the cupcakes to a wire cooling rack and allow them to cool completely before frosting.

Berry Filling

  • Add all of the ingredients to a small saucepan set over medium heat.
    ½ cup raspberries, ½ cup blueberries, ½ cup diced strawberries, 1 tablespoon lemon juice, 1 teaspoon cornstarch
  • Cook, stirring often, for 5-7 minutes or until berries have broken down and the sauce has thickened.
  • Remove the pan from the heat and allow it to cool completely before filling the cupcakes. NOTE: it will continue to thicken as it cools.

Vanilla Mascarpone Frosting

  • Add the softened butter and mascarpone to the bowl of a stand mixer fitted with the paddle attachment. Beat on medium speed until well combined— about 1 minute.
    6 tablespoons unsalted butter, 4 ounces mascarpone cheese
  • Turn the mixer to low speed and slowly add the powdered sugar. When all of the powdered sugar has been incorporated, add the vanilla extract.
    2 ½ cups powdered sugar, 1 teaspoon pure vanilla extract
  • Turn the mixer to medium speed and beat until the frosting is light and fluffy— about 2 minutes.
  • Transfer the frosting to a piping bag fitted with your choice of tip. I’m using a Wilton 2D.

Assembling the cupcakes

  • To assemble the cupcakes, cut a small hole from the center of each cupcake (about the size of quarter and ¼” deep). Keep the removed cake piece removed; it will be added back to the cupcake.
  • Fill the hole with 1-2 teaspoons of berry filling and then place the cut out piece of cake back on top.
  • Pipe the vanilla mascarpone frosting on top of each cupcake and garnish with a fresh berry and/or sprinkles, if desired.

Notes

Store any leftover cupcakes in an airtight container in the refrigerator for up to 2 days
