This is my favorite recipe for homemade vanilla cupcakes. Using creamed butter, cake flour, sour cream, and egg whites, these cupcakes are soft, sweet, fluffy, and infinitely buttery.
- 1 and 3/4 cups (210g) cake flour (spoon & leveled)
- 3/4 teaspoon baking powder
- 1/4 teaspoon baking soda
- 1/4 teaspoon salt
- 1/2 cup (115g) unsalted butter, softened to room temperature
- 1 cup (200g) granulated sugar
- 3 large egg whites, at room temperature
- 2 teaspoons pure vanilla extract
- seeds scraped from 1/2 of a vanilla bean
- 1/2 cup (120g) full-fat sour cream at room temperature
- 1/2 cup (120ml) whole milk at room temperature
- vanilla buttercream and sprinkles for decorating (I use Sweetapolita brand)
- Preheat the oven to 350°F (177°C). Line a 12-cup muffin pan with cupcake liners. Line a second pan with 2 liners – this recipe makes about 14 cupcakes. Set aside.
- Whisk the cake flour, baking powder, baking soda, and salt together. Set aside.
- Using a handheld or stand mixer fitted with a paddle attachment, beat the butter on high speed until smooth and creamy, about 1 minute. Add the sugar and beat on high speed for 2 minutes until creamed together. Scrape down the sides and up the bottom of the bowl with a rubber spatula as needed. Add the egg whites, vanilla extract, and vanilla bean. Beat on medium-high speed until combined, then beat in the sour cream. Scrape down the sides and up the bottom of the bowl as needed. With the mixer on low speed, add the dry ingredients until just incorporated. With the mixer still running on low, slowly pour in the milk until combined. Do not over-mix. You may need to whisk it all by hand 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. For around 30 mini cupcakes, bake for about 11-13 minutes, same oven temperature. Allow the cupcakes to cool completely before frosting.
- Frost cooled cupcakes with vanilla buttercream. I simply used an icing knife. Leftover cupcakes keep well covered tightly in the refrigerator for 3 days.
- Make Ahead & Freezing Instructions: Cupcakes can be made ahead 1 day in advance, covered, and stored at room temperature. Frosting can also be made 1 day in advance, covered, and stored in the refrigerator until ready to use. Frosted or unfrosted cupcakes can be frozen up to 2-3 months. Thaw overnight in the refrigerator.
- Cake Flour: If you can’t get your hands on cake flour, use this cake flour substitute. I suggest doing this twice, mixing it all up in 1 bowl then removing 1/4 cup since you need 1 and 3/4 cups in this recipe.

- Vanilla: For best flavor, pure vanilla extract is strongly recommended. If using imitation, increase to 1 Tablespoon (3 teaspoons). If you can’t get your hands on vanilla bean, simply leave it out or replace with an extra 1/2 teaspoon of pure vanilla extract.
- Whole Milk & Sour Cream: Whole milk and sour cream are strongly recommended for the best taste and texture. A full fat plain yogurt would work instead, though the cupcakes may not be as light. Same goes with a lower fat milk.
- Room Temperature Ingredients: All refrigerated items should be at room temperature so the batter mixes together easily and evenly. Read here for more information.
- Vanilla Cake: I suggest following my white cake recipe as the base, which is almost double this cupcake recipe. I also have a taller vanilla cake recipe as well.
