- 1 1/4 cups all-purpose flour: Provides the structure and body for the cupcakes.
- 1 1/4 teaspoons baking powder: Helps the cupcakes rise and stay airy.
- 1/2 teaspoon baking soda: Adds a tender crumb and balances acidity.
- 1/4 teaspoon salt: Enhances and brightens all the flavors.

- 1 teaspoon vanilla extract: Infuses that classic vanilla aroma and flavor.
- 1/2 cup sour cream: Keeps the cupcakes moist and adds a subtle tang.
- 1/2 cup whole milk: Balances the batter and keeps it smooth.

- 2 cups powdered sugar: Sweetens and thickens the frosting perfectly.
- 1 teaspoon vanilla extract (for frosting): Gives the frosting its signature vanilla flavor.

How to Make Mini Vanilla Cupcakes with Fluffy Buttercream Frosting Recipe
Step 1: Prep Your Oven and Pans
Start by preheating your oven to 350°F (175°C). While waiting, line your mini muffin pans with mini cupcake liners. This step sets the foundation, ensuring your cupcakes bake evenly and come out effortlessly when it’s time.
Step 2: Combine Dry Ingredients
Grab a medium bowl and whisk together the all-purpose flour, baking powder, baking soda, and salt. Mixing these dry ingredients beforehand helps distribute the rising agents and seasoning evenly throughout the batter for perfectly textured cupcakes.
Step 3: Cream Butter and Sugar
In a large bowl, beat the softened butter and granulated sugar until the mixture is light and fluffy. This aerates the batter, giving your cupcakes a tender and airy crumb. Then, add the eggs one at a time, mixing well after each addition to keep the batter smooth and well combined. Stir in the vanilla extract to infuse that classic vanilla aroma.
Step 4: Alternate Adding Dry Ingredients and Dairy
Now slowly incorporate the dry ingredients into the wet mixture, alternating with the sour cream and whole milk. Begin and end with the dry ingredients. This alternating method prevents overmixing and keeps the cupcakes soft and moist. Mix everything just until combined—no need to overwork this batter!
Step 5: Fill the Mini Muffin Pans and Bake
Spoon the batter into the lined mini muffin pans, filling each about two-thirds full to give them room to expand. Pop them into the oven and bake for 10 to 12 minutes, or until a toothpick inserted into the center comes out clean. Your kitchen will start to smell heavenly about halfway through.
Step 6: Cool the Cupcakes
Once baked, allow the cupcakes to cool in their pans for a few minutes before transferring them to a wire rack. Cooling completely is essential before frosting so the buttercream doesn’t melt or slide off.
Step 7: Make the Fluffy Buttercream Frosting
Beat the softened butter until creamy and smooth. Then gradually add powdered sugar, one cup at a time, beating well after each addition to avoid lumps and achieve a luscious texture. Stir in vanilla extract and add heavy cream little by little until the frosting becomes fluffy and spreadable. If you want, add food coloring to match your theme or mood!
Step 8: Frost and Decorate
When the cupcakes are fully cooled, use a piping bag or a spatula to frost each mini cupcake generously. Top with sprinkles or other fun toppings to add personality or celebrate a special occasion.

These creative presentations make the Mini Vanilla Cupcakes with Fluffy Buttercream Frosting Recipe the star of your gatherings.
Make Ahead and Storage
Storing Leftovers
Keep leftover mini cupcakes in an airtight container at room temperature for up to two days to preserve the freshness of both the cake and frosting. For longer storage, refrigeration is an option but can dry out the cupcakes slightly, so allow them to come to room temperature before enjoying.
Freezing
You can freeze unfrosted mini cupcakes in a single layer on a baking sheet, then transfer them to a freezer-safe container for up to three months. Thaw completely before frosting. Alternatively, freeze frosted cupcakes carefully on a tray and then wrap individually for protection, although the texture of the frosting might change slightly.
Reheating
To bring back that fresh-baked feel, warm your cupcakes in the microwave for about 10 seconds or until just heated through. Avoid overheating to prevent drying out. This little trick makes leftover cupcakes taste just as delightful as when freshly baked.
FAQs
Can I use a different kind of milk?
Absolutely! While whole milk adds richness, you can substitute with 2% or even a plant-based milk like almond or oat milk. Just be aware that the final texture might vary slightly with different milks.
Can I make these cupcakes larger?
Yes, you can simply bake them in a regular muffin pan, but increase the baking time to about 18 to 22 minutes. Keep an eye on them and test for doneness with a toothpick.
How do I prevent the buttercream from being too sweet?
Adding a small pinch of salt or a little vanilla bean paste instead of extract can deepen the flavor and balance the sweetness. Also, adjusting the amount of powdered sugar to your taste helps make it just right.
Can I use store-bought frosting instead?
You can, but homemade buttercream really elevates this recipe with its fresh flavor and texture. If convenience is key, choose a high-quality buttercream for the best results.
What is the best way to pipe the frosting?
A classic star tip works beautifully to create pretty swirls that showcase the fluffy texture. If you’re using a spatula, keep strokes gentle and smooth for a clean finish.
