How to Make Funfetti Cupcakes with Vanilla Bean Buttercream
Bake the Funfetti Cupcakes
Preheat the oven to 350°F (175°C) and line a 12-cup cupcake pan with paper liners. Set aside.
In the bowl of a stand mixer fitted with the paddle attachment, combine the sugar, room-temperature butter, and oil. Beat on medium for about 5 minutes, until the mixture is very light and fluffy.

In a small bowl, whisk together the whole egg and egg whites. With the mixer running on low, slowly add the beaten eggs to the butter mixture. Mix until combined, scraping down the sides and bottom of the bowl with a rubber spatula to ensure everything is fully incorporated.
In a separate bowl, whisk together the flour, baking powder, and salt. In a measuring cup, combine the buttermilk and vanilla extract. Add the dry ingredients and the buttermilk mixture to the mixer in five alternating additions, beginning and ending with the dry ingredients (for example: 1/3 dry, 1/2 wet, repeat). Take care not to overmix.
Toss the rainbow sprinkles in a little flour to prevent bleeding, then gently fold them into the batter with a rubber spatula until evenly distributed.

Portion the batter evenly into the prepared liners using a standard ice cream scoop or spoon. Bake at 350°F for 18–20 minutes, or until a toothpick inserted into the center comes out mostly clean with a few moist crumbs attached.
Allow the cupcakes to cool in the pan for a few minutes, then transfer them to a cooling rack to cool completely before frosting.

Make the Vanilla Bean Buttercream
In the bowl of a stand mixer with the paddle attachment, beat the room-temperature butter on its own for 10 minutes, scraping the bowl halfway through. The butter should become very smooth and pale.
Add the salt and vanilla bean paste, then mix to combine. Gradually add the powdered sugar in two additions, beating for about 3 minutes after each addition. Add the heavy cream one tablespoon at a time until the frosting reaches your desired consistency—light and fluffy but still pipeable.
Transfer the buttercream to a piping bag fitted with your preferred tip (a Wilton 1M works well) and pipe generous swirls on the cooled cupcakes. Serve and enjoy.
