What Ingredients You Will Need

This recipe uses simple, everyday ingredients to create cupcakes that are both flavorful and irresistibly pretty. If you bake even occasionally, you’ll likely have most items on hand. Here’s what you’ll need for the cupcakes and the whipped buttercream frosting:

For the Funfetti Cupcake Batter:

• 1 2/3 cups (210g) all-purpose flour (sifted for best results)
• 1 cup (200g) granulated sugar
• 1/2 cup (113g) unsalted butter, softened (brings richness—use a good quality brand like Kerrygold for flavor)
• 1/4 cup (60g) sour cream, room temperature (keeps cupcakes moist; Greek yogurt works as a substitute)
• 1/2 cup (120ml) whole milk, room temperature (almond or oat milk also work)
• 2 large eggs, room temperature
• 2 teaspoons pure vanilla extract (use real vanilla if you can—it’s worth it!)
• 1 1/2 teaspoons baking powder
• 1/4 teaspoon baking soda
• 1/4 teaspoon fine sea salt
• 1/2 cup (80g) rainbow jimmies sprinkles (avoid nonpareils—they bleed in the batter; Sweetapolita is my go-to brand)

For the Whipped Buttercream:

• 1 cup (226g) unsalted butter, softened to room temperature
• 2 1/2 cups (310g) powdered sugar, sifted
• 2–3 tablespoons (30–45ml) heavy cream (or whole milk in a pinch)
• 1 teaspoon pure vanilla extract
• 1/8 teaspoon fine sea salt

For Decorating:

• Extra rainbow jimmies for topping (because more is more!)

Ingredient Tips: If you’re baking for someone gluten-free, swap the all-purpose flour for a 1:1 gluten-free baking blend. Dairy-free? Use a plant-based butter and milk. And if you’re out of sour cream, Greek yogurt works beautifully—tried and tested during an “oops, I’m out” moment!

Equipment Needed

• 12-cup muffin tin – Standard size is perfect for this recipe. I use a nonstick pan, but metal or ceramic both work.
• Paper cupcake liners – Makes cleanup easy and helps the cupcakes release cleanly. Silicone liners are a reusable alternative.
• Electric mixer – Either a hand mixer or stand mixer is great for creaming the butter and whipping the frosting. I’ve used both; a hand mixer is totally fine if that’s what you have!
• Mixing bowls – At least two: one for the batter, one for the frosting.
• Measuring cups and spoons – Accurate measurements make a difference here, especially for flour and sugar.
• Rubber spatula – For scraping the bowl and gently folding in the sprinkles (so they don’t break up too much).
• Ice cream scoop or large spoon – For evenly portioning the cupcake batter into liners. It’s a little trick for consistent size!
• Wire cooling rack – Helps the cupcakes cool quickly and evenly.
• Piping bag and tip (optional) – For a bakery-style frosting swirl. No piping bag? Snip the corner off a zip-top bag or just use a butter knife for a rustic look.

Budget Tip: If you’re just getting started, most dollar stores carry cupcake pans and mixing bowls that do the job. I started out with hand-me-down equipment and, honestly, it worked just fine!

How to Make Funfetti Birthday Cupcakes

1. Preheat and Prep:
   Preheat your oven to 350°F (175°C). Line a standard 12-cup muffin tin with paper cupcake liners. (I always do this first so I’m not scrambling with sticky hands later!)
2. Mix Dry Ingredients:
   In a medium bowl, whisk together 1 2/3 cups (210g) all-purpose flour, 1 1/2 teaspoons baking powder, 1/4 teaspoon baking soda, and 1/4 teaspoon salt. Set aside.
3. Cream Butter & Sugar:
   In a large mixing bowl, use an electric mixer to beat 1/2 cup (113g) unsalted butter and 1 cup (200g) granulated sugar on medium speed until light and fluffy, about 2-3 minutes. The mixture should look pale and aerated.
4. Add Eggs & Vanilla:
   Beat in 2 large eggs, one at a time, mixing well after each. Add 2 teaspoons vanilla extract and mix until smooth. (If the mixture looks a bit curdled, don’t panic—it’ll come together when you add the dry and wet ingredients.)
5. Combine Wet Ingredients:
   In a small bowl or measuring cup, whisk together 1/2 cup (120ml) whole milk and 1/4 cup (60g) sour cream.
6. Alternate Adding Dry and Wet Mixtures:
   With the mixer on low, add half the dry ingredients to the butter mixture, then the milk/sour cream mixture, then the rest of the dry ingredients. Mix until just combined—don’t overmix, or your cupcakes might be dense. (Stop as soon as you see no more streaks of flour.)
7. Fold in Sprinkles:
   Gently fold in 1/2 cup (80g) rainbow jimmies using a rubber spatula. Stir just enough to distribute—overmixing can cause colors to bleed.
8. Fill Liners:
   Divide the batter evenly among cupcake liners, filling each about 2/3 full. (An ice cream scoop gives perfect portions and less mess.)
9. Bake:
   Bake for 17-20 minutes, or until the tops are lightly golden and a toothpick inserted into the center comes out clean or with just a few moist crumbs. (Mine are usually perfect at 18 minutes, but ovens vary.)
10. Cool:
    Let cupcakes cool in the pan for 5 minutes, then transfer to a wire rack to cool completely before frosting. (Don’t frost warm cupcakes—the buttercream will melt right off!)
11. Make Whipped Buttercream:
    In a large bowl, beat 1 cup (226g) unsalted butter on medium-high for 3-4 minutes, until super light and creamy. Gradually add 2 1/2 cups (310g) powdered sugar, mixing on low after each addition. Add 2-3 tablespoons (30–45ml) heavy cream, 1 teaspoon vanilla, and 1/8 teaspoon salt. Whip on high for another 2 minutes until fluffy and pale. (If the frosting seems too thick, add a splash more cream; too thin, add a little more sugar.)
12. Frost and Decorate:
    Spread or pipe the whipped buttercream onto cooled cupcakes. Finish with extra rainbow sprinkles on top. (I always let my kids help with this part—no such thing as too many sprinkles!)
    Tip: If you want a bakery-style swirl, use a large open star piping tip. Or go rustic and spread with a butter knife for a homemade vibe.

Troubleshooting: If your cupcakes sink in the middle, they may be underbaked—give them a minute or two more next time. If the sprinkles seem to disappear, double-check you’re using jimmies, not nonpareils.

Cooking Tips & Techniques

• Room Temperature Ingredients: Always use room temp butter, eggs, and dairy. This helps the batter come together smoothly and gives you fluffier cupcakes. Cold ingredients can make the batter lumpy (learned that the hard way!).
• Don’t Overmix: After adding the flour, mix just until you see no dry streaks. Overmixing leads to dense, tough cupcakes. If in doubt, stop early and finish folding by hand.
• Sprinkle Selection: Stick to jimmies-style sprinkles for the best Funfetti effect. Nonpareils and confetti shapes melt or bleed—your batter will turn muddy. Trust me, it’s happened.
• Baking Evenness: Rotate your cupcake pan halfway through baking if your oven has hot spots. This helps all cupcakes brown evenly.
• Testing Doneness: Insert a toothpick in the center—if it comes out clean or with a few moist crumbs, they’re done. Don’t wait for it to come out bone dry, or you’ll have dry cupcakes.
• Frosting Consistency: Whipped buttercream should be light and spreadable. If it’s too runny, pop it in the fridge for ten minutes. If it’s too stiff, add a splash more cream and beat again.
• Batch Baking: Doubling the recipe? Only mix in the sprinkles right before baking each batch, or the colors can bleed if they sit in the batter too long.

Honestly, I’ve had my share of cupcake fails—flat tops, sunken middles, even a batch that tasted like a sprinkle factory exploded. The key is not sweating the small stuff; even “imperfect” cupcakes taste amazing, and that’s what really matters. Practice, patience, and a little extra vanilla are the real secrets to success!

Variations & Adaptations

• Gluten-Free: Swap the all-purpose flour for a 1:1 gluten-free baking blend. I’ve used King Arthur’s with great results—no one could even tell the difference!
• Dairy-Free: Use plant-based butter (like Earth Balance), almond or oat milk, and coconut yogurt in place of sour cream. The cupcakes stay moist and still taste like classic Funfetti.
• Flavor Twist: Add a teaspoon of almond extract to the batter for a bakery-style flavor, or fold in mini chocolate chips for a chocolatey surprise.
• Seasonal Fun: Use themed sprinkles for holidays—red, white, and blue for Fourth of July; pastels for Easter; or orange and black for Halloween. I love switching it up for every season!
• Mini Cupcakes: Make bite-size treats by baking in a mini muffin tin; reduce the bake time to about 10-12 minutes. Great for parties or little hands.
• Allergen-Friendly: For egg-free cupcakes, substitute each egg with 1/4 cup unsweetened applesauce or a flaxseed egg (1 tablespoon flaxseed meal + 2.5 tablespoons water, let sit 5 minutes). Worked like a charm for my nephew’s birthday!

My personal favorite twist? Swapping half the vanilla for lemon or orange zest in the batter. The citrus brightens the whole cupcake and tastes like sunshine—so good for spring parties!

Serving & Storage Suggestions

Funfetti Birthday Cupcakes are best served at room temperature, when the buttercream is soft and fluffy. Arrange them on a pretty cake stand or platter, and don’t forget the extra sprinkle shower right before serving—it makes them pop for photos!

• Serving Ideas: Pair with cold milk, fruit punch, or sparkling lemonade for a true party feel. They also play nicely with coffee or tea if you’re celebrating with adults.
• Storage: Store cupcakes in an airtight container at room temperature for up to 2 days. If your kitchen is warm, stash them in the fridge—but let them sit out for 20 minutes before serving so the buttercream softens.
• Freezing: Freeze unfrosted cupcakes for up to 2 months. Thaw overnight at room temperature, then frost fresh. You can also freeze frosted cupcakes—just flash-freeze on a baking sheet, then wrap tightly.
• Reheating: Not needed, but if you want to freshen them up, a quick 5-second zap in the microwave will do it. (Just don’t overdo it or the buttercream could melt!)
• Flavor Note: The flavors deepen after a day—so if you have the willpower, make them ahead and let the vanilla and sprinkles work their magic.

FAQs

How do I stop the sprinkles from bleeding in my Funfetti birthday cupcakes?

Use jimmies-style sprinkles—they hold their color best in the batter. Fold them in gently just before baking, and avoid nonpareils or confetti shapes, which tend to bleed.

Can I make these Funfetti birthday cupcakes ahead of time?

Absolutely! The cupcakes can be baked a day ahead and stored, unfrosted, in an airtight container. Frost them fresh before serving for the best texture.

How do I make these cupcakes gluten-free?

Swap the all-purpose flour for a 1:1 gluten-free baking blend. I recommend King Arthur or Bob’s Red Mill for reliable results.

What’s the best way to get bakery-style frosting swirls?

Use a large open star piping tip and a piping bag. Start at the outside edge of the cupcake and spiral inward, finishing with a little peak on top. No piping bag? Snip the corner off a zip-top bag—it works in a pinch!

Can I use this recipe to make a cake instead of cupcakes?

Yes! Pour the batter into a greased 8-inch cake pan and bake at 350°F (175°C) for about 25–30 minutes. Keep an eye on it and check with a toothpick for doneness.
