Funfetti cupcakes are pure joy — bright, tender, and a little nostalgic. Topped with a cloud of vanilla bean buttercream, they make a perfect snack or party treat. Below is a straightforward recipe to make a small batch of 12 cupcakes with an easy, fluffy buttercream.

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 muffin pan with liners.

In the bowl of a stand mixer fitted with the paddle attachment, cream the sugar, room-temperature butter, and oil on medium speed for about 5 minutes, until the mixture is very light and fluffy.

Mixing batter

In a small bowl, whisk together the whole egg and the egg whites. With the mixer on low, slowly add the beaten eggs to the butter-sugar mixture and mix until combined. Scrape the bowl with a rubber spatula to incorporate any ingredients clinging to the sides or bottom.

In another bowl, whisk the all-purpose flour, baking powder, and salt. In a measuring cup, stir together the buttermilk and vanilla extract. Add the dry ingredients and the buttermilk mixture to the mixer alternately in five additions, beginning and ending with the dry ingredients. Mix just until combined — do not overmix.

Toss the rainbow sprinkles with a little flour to prevent bleeding, then gently fold them into the batter with a rubber spatula until evenly distributed.

Scooping batter

Portion the batter evenly into the liners using a standard ice cream scoop or tablespoon. 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. Let the cupcakes rest in the pan for a few minutes, then transfer to a wire rack to cool completely before frosting.

Make the Vanilla Bean Buttercream

In the stand mixer bowl with the paddle attachment, beat the room-temperature butter on its own for about 10 minutes, scraping down the bowl halfway through. The butter should become lighter in color and very smooth.

Add the salt and vanilla bean paste, then combine. Add the powdered sugar in two additions, mixing for about 3 minutes after each addition to fully incorporate and aerate the frosting. Add heavy cream one tablespoon at a time until you reach a fluffy but pipeable consistency.

Fill a piping bag fitted with your preferred tip (a Wilton 1M gives a classic swirled look) and pipe the buttercream onto cooled cupcakes. Serve and enjoy.
