Learn all the tips for making perfect Mini Vanilla Cupcakes – moist, fluffy, topped with silky vanilla buttercream, and irresistibly cute!
In November my sister is getting married. I’m not making the wedding cake (I plan to be stress-free and sip a mimosa before the ceremony), but I will celebrate with a tray of mini vanilla cupcakes.
Mini vanilla cupcakes are a perfect celebration treat: tender, moist, and light, with a pretty swirl of buttercream on top. They’re bite-sized, elegant on a dessert table, and disappear fast. Mini desserts are charming, easier to serve, and harder to resist.
A whole tray looks like a bed of little vanilla cupcakes — sweet and inviting.
You don’t need a special occasion to bake these. Whether you’re making mini cupcakes for a shower, a birthday, or just because, these tips and the recipe below will help you bake consistently great mini vanilla cupcakes.
For the Mini Cupcake Batter
This recipe produces cupcakes that are both moist and airy. The moisture comes from buttermilk and sour cream, while the light, delicate crumb comes from a mix of all-purpose flour and cornstarch. That combination mimics cake flour and keeps the texture tender without sacrificing structure.
The batter is slightly thicker than some classic cupcake batters—intentionally so. Mini cupcakes need to hold up under frosting, so a sturdier batter helps prevent them from collapsing under the swirl of buttercream.
How to Bake Mini Cupcakes
Use a proper mini muffin or mini cupcake pan and line each cavity with mini muffin paper liners (not candy cup liners — those are too small and cause overflow). You’ll get about 35–40 mini cupcakes from this batch.
Fill each liner about 2/3 to 3/4 full. A small cookie scoop (2 teaspoons or 1 tablespoon size) makes portioning quick and consistent. Bake at 350°F for roughly 11–13 minutes, checking at 10 minutes since mini cupcakes can brown quickly. They’re done when a toothpick inserted in the center comes out clean. Keep the oven rack centered to ensure even baking.
For the Vanilla Buttercream
Piping frosting on many mini cupcakes is the most time-consuming step, but the result is worth it. For stability on a dessert table, this buttercream blends butter with a bit of shortening. Shortening helps the frosting stay firm at room temperature and keeps the color whiter if you use clear vanilla extract. If you prefer, you can use all butter instead, but the frosting may soften more quickly.
Use heavy cream or whipping cream rather than milk for a richer, creamier buttercream. Adjust the powdered sugar to reach your preferred sweetness and texture. A piping bag with a 1M Wilton tip gives the classic swirl, but you can also spread frosting with a small offset spatula.
I’ve made this recipe several times for pre-wedding celebrations and loved how consistently tender and flavorful the cupcakes turn out. Next time I’ll adapt the same method to mini chocolate cupcakes!

Ingredients
For the Mini Cupcakes
- 1 and 1/3 cup all-purpose flour, spooned & leveled
- 1/4 cup cornstarch
- 1/2 teaspoon baking soda
- 1/2 teaspoon baking powder
- 1/4 teaspoon salt
- 1/2 cup unsalted butter, softened to room temperature
- 1 cup granulated sugar
- 2 teaspoons vanilla extract
- 2 large eggs, room temperature
- 3 tablespoons sour cream
- 1/2 cup buttermilk, room temperature (2% or whole milk also work)
For The Vanilla Buttercream
- 2/3 cup unsalted butter, softened to room temperature
- 1/4 cup shortening
- 1/2 teaspoon salt
- 2 teaspoons vanilla
- 4 to 5 cups powdered sugar, sifted
- 3-5 tablespoons heavy cream
Instructions
For the Mini Cupcakes
-
Preheat the oven to 350°F and position the oven rack in the center.
-
Line mini muffin pans with mini paper liners (avoid candy cup wrappers). You should get about 35–40 cupcakes.
-
Whisk together the flour, cornstarch, baking soda, baking powder, and salt in a large bowl.
-
In a separate large bowl, beat the butter and sugar with an electric mixer on medium speed until fluffy. Add the eggs and vanilla and continue beating.
-
Turn off the mixer, scrape down the bowl, then stir in the sour cream.
-
With the mixer on low speed, add the flour mixture followed by the buttermilk. Mix just until combined; do not overmix.
-
Fill each liner about 2/3 to 3/4 full using a small cookie scoop for consistency.
-
Bake for 11–13 minutes, or until a toothpick comes out clean. Begin checking at 10 minutes to avoid over-browning.
For the Vanilla Buttercream
-
Beat the butter and shortening together in a large bowl for about 2 minutes. It’s okay if there are small clumps. Mix in the vanilla and salt.
-
On low speed, beat in 3½ cups of powdered sugar. Add the remaining powdered sugar and heavy cream slowly until you reach the desired sweetness and consistency.
-
If using food coloring, add it now. Then beat on medium-high for about 20 seconds to make the frosting fluffy.
-
Frost cupcakes with a small offset knife or pipe the buttercream using a piping bag and a 1M tip for a classic swirl.
