Ingredients
Cupcakes
- 1 and 3/4 cups (207g) cake flour (spooned & leveled)
- 3/4 teaspoon baking powder
- 1/4 teaspoon baking soda
- 1/4 teaspoon salt
- 1/2 cup (1 stick) unsalted butter, softened to room temperature
- 1 cup (200g) granulated sugar
- 3 large egg whites, at room temperature
- 1/2 cup (120g) full-fat sour cream at room temperature
- 2 teaspoons pure vanilla extract
- seeds scraped from 1/2 of a vanilla bean (optional)
- 1/2 cup (120g) whole milk at room temperature
Frosting
- 1 cup (2 sticks) unsalted butter, softened to room temperature
- 4 – 5 cups (480-600g) confectioners’ sugar
- 1/4 cup heavy cream, half-and-half, or whole milk, at room temperature
- 2 teaspoons pure vanilla extract
- salt, to taste
Directions
For the cupcakes:
- Preheat the oven to 350°F. Line a 12-cup muffin pan with cupcake liners. Line a second pan with 2 liners—this recipe makes about 14 cupcakes. Set aside.
- In a medium bowl, whisk the cake flour, baking powder, baking soda, and salt together. Set aside.
- In a large bowl using a handheld or stand mixer fitted with a paddle attachment, beat the butter and sugar on high speed until light and creamy, about 3 minutes. Scrape down the sides of the bowl as needed.
- Add the egg whites, vanilla extract, and vanilla bean seeds (if using) and beat on high speed until smooth and well combined, about 2 minutes.
- Add the sour cream and beat on medium-high speed until combined, about 1 minute.
- With the mixer running on low speed, add the dry ingredients, and then slowly pour in the milk and beat just until combined. Do not over-mix. You may need to whisk it by hand a few times to make sure there are no lumps at the bottom of the bowl. The batter will be slightly thick.
- Pour/spoon the batter into the liners—fill only 2/3 full to avoid spilling over the sides.
- Bake for 19–22 minutes, or until a toothpick inserted in the center comes out clean.
- Cool the cupcakes in the pan set on a cooling rack for 20 minutes, then remove them from the pan and return to the rack to cool completely before frosting.
For the frosting:
- With a handheld or stand mixer fitted with a paddle attachment, beat the butter on medium speed until creamy, about 2 minutes.
- Add 4 and 1/2 cups confectioners’ sugar, the heavy cream, and vanilla extract.
- Beat on low speed for 30 seconds, then increase to medium-high speed and beat for 2 full minutes. Taste. Add a pinch of salt if frosting is too sweet. I always add 1/8 teaspoon.
- Adjust if needed: You can control the consistency at this point—add up to 1/2 cup more confectioners’ sugar if frosting is too thin or more heavy cream if frosting is too thick (add only 1 Tablespoon at a time, beat together, then taste and add more if desired).
- Use immediately or cover tightly and store for up to 1 week in the refrigerator or up to 3 months in the freezer. After freezing, thaw in the refrigerator then beat the frosting on medium speed for a few seconds so it’s creamy again. After thawing or refrigerating, beating in a splash of heavy cream or milk will help thin the frosting out again, if needed.
- Frost cooled cupcakes with vanilla buttercream. You can swipe the frosting on with an icing knife or use a piping tip such as Wilton 1M. Store covered in the refrigerator for up to 3 days.
