Ingredients You’ll Need

1 1/2 cups + 2 tablespoons unbleached cake flour: This forms the base for our cupcakes and is key for that soft, tender crumb. Be sure to spoon and level it for accuracy.
1 cup granulated sugar: Sweetness is essential, and granulated sugar helps create that light texture.
2 teaspoons baking powder: This leavening agent gives the cupcakes their height and fluffy structure.
2 teaspoons vanilla powder: Adds a rich, mellow flavor that makes these cupcakes stand out. You can substitute with pure vanilla extract if you prefer.
3/4 teaspoon fine sea salt: Enhances all the flavors without making these treats taste salty.
8 tablespoons unsalted butter, cubed, room temperature: Butter provides flavor and richness, making the cupcakes decadent.
2 large eggs, room temperature: These bring moisture and bind the ingredients together.
1/3 cup whole milk, room temperature: Keeps the batter moist and tender; it can be swapped for almond milk for a dairy-free option.
1/3 cup heavy cream, room temperature: Adds richness and creamy texture, ensuring the cupcakes are truly indulgent.
1/3 cup sour cream, room temperature: This ingredient adds moisture and a subtle tang, enhancing flavor.
2 tablespoons + 2 teaspoons vegetable oil: Oil contributes to the cupcakes’ moistness without weighing them down.
2 teaspoons imitation vanilla: Gives a classic boxed cake flavor; feel free to use real vanilla for a more elevated taste.
1/4 cup rainbow sprinkles: These add a fun pop of color and celebrate the joyous occasion.
5 large egg whites: Used to create the fluffy meringue buttercream that crowns the cupcakes.
1 1/2 cups granulated sugar for meringue: This forms a stable and sweet meringue.
2 cups unsalted butter, room temperature & cut into tablespoon pieces: Creamy and rich, it makes the buttercream smooth and luscious.
1 tablespoon vanilla bean paste: Provides flecks of real vanilla, adding flavor and making the buttercream look impressive.
Extra sprinkles for decorating: Because who can resist more sprinkles?

How to Make The Only Birthday Cupcakes I Ever Make

Preheat the Oven: Set your oven to 325°F (160°C). Line a cupcake pan with cupcake liners and set it aside.
Mix the Dry Ingredients: In a stand mixer bowl, whisk together 1 1/2 cups + 2 tablespoons unbleached cake flour, 1 cup granulated sugar, 2 teaspoons baking powder, 2 teaspoons vanilla powder, and 3/4 teaspoon fine sea salt.
Incorporate Butter: Mix in 8 tablespoons of cubed unsalted butter on low speed until the mixture has a sandy texture.
Prepare Wet Ingredients: In a separate bowl, whisk together 2 large room temperature eggs, 1/3 cup whole milk, 1/3 cup heavy cream, 1/3 cup sour cream, 2 tablespoons + 2 teaspoons vegetable oil, and 2 teaspoons imitation vanilla.
Combine Wet and Dry Ingredients: Gradually mix in half of the wet ingredients until the flour is moistened; scrape down the bowl. Then, add the remaining wet ingredients and 1/4 cup rainbow sprinkles, mixing on low speed until just incorporated.
Fill the Liners: Fill each cupcake liner about 3/4 full. You should have enough batter to make approximately 15 cupcakes.
Bake: Slide the pan into the preheated oven and bake for 25-30 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs.
Cool the Cupcakes: Allow the pan to cool on a wire rack for about 10-15 minutes. Once cooled slightly, remove the cupcakes from the pan and let them cool completely on the rack.
Prepare the Meringue Buttercream: In a large bowl over a double boiler with simmering water, whisk 5 large egg whites and 1 1/2 cups granulated sugar until the mixture reaches 165°F (74°C) and the sugar is dissolved.
Whisk the Meringue: Transfer the warmed meringue to a stand mixer bowl fitted with the whisk attachment. Whisk on high speed until it cools to about 90-95°F (around 10-15 minutes).
Incorporate Butter: With the mixer on low, add 2 cups of room temperature unsalted butter, 1-2 tablespoons at a time, until all the butter is incorporated. Increase the speed to medium-high and beat until the buttercream is light and fluffy. Then, mix in 1 tablespoon of vanilla bean paste.
Decorate the Cupcakes: Fit a large piping bag with an open star tip and fill it with the buttercream. Pipe swirls on each cooled cupcake and sprinkle with extra sprinkles for a festive touch.

Storing & Reheating

To keep your cupcakes fresh, store them at room temperature in an airtight container for up to 2 days. For longer storage, refrigerate them for up to a week; however, they can dry out slightly in the fridge. If you want to freeze them, wrap each cupcake tightly in plastic wrap and place them in a freezer-safe container for up to 3 months. To enjoy, thaw at room temperature, or pop them in the microwave for 10-15 seconds to refresh their moist texture.

Chef’s Helpful Tips

Be sure your eggs, butter, and dairy ingredients are at room temperature to achieve a better texture.
Avoid overmixing the batter once combined; this helps retain the cupcakes’ lightness.
If your buttercream looks curdled, don’t fret! Just continue to mix, and it will come back together into a smooth frosting.
Feel free to experiment with different types of sprinkles or toppings to match your party theme!
For a fun twist, try adding flavored extracts like almond or lemon to the batter or frosting.

Recipe FAQs

Can I make these cupcakes ahead of time?

Yes! You can bake the cupcakes a day in advance. Store them in an airtight container at room temperature. The buttercream can also be made ahead and stored in the refrigerator; just let it soften before frosting the cupcakes.

How can I make these cupcakes gluten-free?

Swap the unbleached cake flour for a 1:1 gluten-free baking blend to achieve a similar texture. The rest of the ingredients can remain the same.

What should I do if my buttercream is too soft?

If your buttercream feels too soft, chill it in the refrigerator for 10-15 minutes, then re-whip it until it becomes fluffy again. This can help stabilize it if it’s too warm.

Can I use different flavors for these cupcakes?

Absolutely! You can switch out the vanilla powder for other flavors like almond or lemon. You can also incorporate different add-ins like chocolate chips or nuts for additional flavor and texture!
