- 1 1/4 cups all-purpose flour: Provides the perfect base for a soft and fluffy cupcake texture.
- 1 1/4 teaspoons baking powder: Helps your mini cupcakes rise beautifully and stay light.
- 1/2 teaspoon baking soda: Works alongside baking powder for even leavening and tenderness.

- 1 cup granulated sugar: Sweetens the batter and helps create a lovely crumb.
- 2 large eggs: Bind everything and contribute to the cake’s structure and softness.
- 1 teaspoon vanilla extract: Provides warm, comforting flavor throughout.
- 1/2 cup sour cream: Adds tenderness and a slight tang that balances the sweetness.
- 1/2 cup whole milk: Keeps the batter moist and smooth.
- 1/2 cup unsalted butter, softened (for frosting): Creates a creamy, dreamy buttercream base.
- 2 cups powdered sugar: Sweetens and thickens the frosting to the perfect consistency.
- 1 teaspoon vanilla extract (for frosting): Infuses that classic vanilla flavor into the buttercream.

How to Make Mini Cupcakes with Vanilla Buttercream Frosting Recipe
Step 1: Prepare Your Oven and Pans
Start by preheating your oven to 350°F (175°C). Line mini muffin pans with cute mini cupcake liners because these little cakes deserve adorable presentation. Proper preparation ensures your cupcakes bake evenly and pop out effortlessly once done.
Step 2: Combine Your Dry Ingredients
In a medium bowl, whisk together the all-purpose flour, baking powder, baking soda, and salt. This mixture is the foundation of your cupcakes’ perfect crumb, so getting it well combined helps ensure every bite has consistent texture.
Step 3: Cream Butter and Sugar
Using a large bowl, beat the softened butter and granulated sugar until the mixture is light, fluffy, and almost pale. This gentle aeration is key to a tender, airy cupcake. Next, add the eggs one at a time, beating well after each addition, followed by stirring in the vanilla extract to infuse lovely fragrance and flavor.
Step 4: Alternate Adding Dry Ingredients, Sour Cream, and Milk
Gradually add the dry ingredients to your wet mixture, alternating with the sour cream and whole milk. Start and end with the dry ingredients for the best distribution. Mix just until combined to avoid overworking the batter, which can create dense cupcakes rather than soft ones.
Step 5: Fill and Bake
Spoon the batter into the lined mini muffin pans, filling each liner about two-thirds full. This leaves room for the cupcakes to rise without spilling over. Bake them for 10 to 12 minutes or until a toothpick inserted into the center comes out clean. The aroma at this point is simply irresistible!
Step 6: Cool Before Frosting
Allow your mini cupcakes to cool in the pans for a few minutes so they firm up a bit. Then transfer them to a wire rack to cool completely. Frosting warm cupcakes can cause the buttercream to melt, so patience here will reward you with a smooth finish.
Step 7: Make the Vanilla Buttercream Frosting
Beat the softened butter until creamy and smooth. Gradually incorporate the powdered sugar, a cup at a time, beating well after each addition. Once fluffy, mix in the vanilla extract and heavy cream until the frosting reaches your desired consistency. If you’d like, add food coloring to customize your frosting shade.
Step 8: Decorate Your Mini Cupcakes
Once completely cooled, frost each cupcake using a piping bag for those elegant swirls or a spatula for a more casual spread. Sprinkle with colorful sprinkles or other fun toppings for that extra festive feel. Now they’re ready to impress!
How to Serve Mini Cupcakes with Vanilla Buttercream Frosting Recipe

Garnishes
Mini cupcakes are like little canvases begging for garnish. From classic rainbow sprinkles to edible glitter, fresh berries, or even tiny candy pieces, garnishes add both texture and visual appeal. Not only do they make your cupcakes pop, but they also offer fun, customizable touches for any occasion.
Side Dishes
Pair these mini delights with a cup of hot tea or freshly brewed coffee for a quintessential cozy pairing. For a brunch spread, consider serving alongside fresh fruit or a light salad to balance the sweetness. They also shine on dessert tables when accompanied by creamy puddings or mousse.
Creative Ways to Present
Presentation makes a huge difference with these small wonders. Arrange them on tiered stands for parties or buffet tables, place each cupcake in decorative mini boxes as gifts, or skirt a large cookie platter with them to create an eye-catching dessert centerpiece. Adding themed cupcake toppers can make them perfect for birthdays or holidays.
Make Ahead and Storage
Storing Leftovers
Store any leftover mini cupcakes in an airtight container at room temperature for up to two days to keep them soft and moist. Refrigerate if your climate is warm or if the buttercream needs extra firming, but bring them back to room temperature before eating to enjoy their full flavor and texture.
Freezing
You can absolutely freeze these mini cupcakes for longer storage. Best practice is to freeze unfrosted cupcakes in a single layer on a baking sheet, then transfer to a sealed container or freezer bag for up to two months. Freeze the frosting separately if possible, and frost cupcakes fresh after thawing.
Reheating
When ready to enjoy frozen cupcakes, let them thaw at room temperature completely. If you want to warm them slightly, a brief 10-second zap in the microwave works wonders, but avoid heating too long so the buttercream doesn’t melt.
FAQs
Can I substitute the sour cream with yogurt?
Absolutely! Plain Greek yogurt is a fantastic substitute for sour cream in this Mini Cupcakes with Vanilla Buttercream Frosting Recipe. It keeps the cupcakes moist and adds that slight tanginess, though you might want to go for full-fat yogurt for the best texture.
What can I use instead of whole milk?
Whole milk adds richness, but you can swap it with 2% milk or even a nut milk like almond or oat. Just keep in mind the flavor and texture might have subtle differences, but your mini cupcakes will still turn out delicious.
How do I make my buttercream frosting less sweet?
If the frosting tastes too sugary, you can reduce the powdered sugar slightly and add a little extra butter or cream to balance it out. A pinch of salt can also help tame sweetness and enhance the vanilla flavor.
Can I use this recipe to make regular-sized cupcakes?
Yes! Just increase the baking time to about 18-22 minutes and fill your cupcake liners about two-thirds full. The texture and flavor will be just as delightful—only larger.
Is there a gluten-free version of this recipe?
You can substitute the all-purpose flour with a gluten-free flour blend designed for baking. Be sure it contains xanthan gum or similar for structure. The taste should remain wonderfully close to the original.
