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.
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
