What Ingredients You Will Need

This fluffy funfetti cake recipe uses simple, wholesome ingredients to deliver bold flavor and a satisfying texture without any fuss. Most of them are pantry staples, and the star here is definitely the rainbow sprinkles that bring the fun factor to life.

  • All-purpose flour – 2 ½ cups (312 g), for the perfect structure
  • Baking powder – 2 ½ teaspoons, to give that fluffy rise
  • Salt – ½ teaspoon, to balance the sweetness
  • Unsalted butter – ¾ cup (170 g), softened (adds richness and tenderness)
  • Granulated sugar – 1 ¾ cups (350 g), for sweetness
  • Large eggs – 4, room temperature (helps with emulsification and structure)
  • Pure vanilla extract – 2 teaspoons, for that classic funfetti flavor
  • Whole milk – 1 cup (240 ml), room temperature (keeps the crumb moist)
  • Sour cream – ½ cup (120 g), room temperature (secret ingredient for moistness)
  • Rainbow sprinkles – ¾ cup (about 120 g), plus extra for topping (choose sturdy ones that don’t bleed color)

For best results, I recommend using a trusted brand like Wilton for sprinkles—they hold up well in the batter and don’t turn your cake into a rainbow mess. If you want a dairy-free version, swap the milk and sour cream for your favorite plant-based alternatives like almond milk and coconut yogurt. Fresh seasonal fruit can also make a fun topping if you want to mix things up.

Equipment Needed

  • Two 8-inch (20 cm) round cake pans – For even baking and that classic layered look; if you don’t have these, two 9-inch pans work fine.
  • Electric mixer or stand mixer – Makes cream butter and sugar effortless; a hand mixer will do in a pinch.
  • Mixing bowls – One large for dry ingredients, one medium for wet ingredients.
  • Measuring cups and spoons – Accuracy is key for baking success.
  • Rubber spatula – For folding in the sprinkles gently without breaking them.
  • Cooling racks – To let the cake cool evenly and avoid sogginess.
  • Optional: Parchment paper – To line pans for easy release; I always recommend it to avoid sticking.

Personally, I find silicone spatulas the best for folding in sprinkles—they’re gentle but sturdy. If you’re on a budget, thrift stores often have cake pans and measuring tools in good shape. And a tip from experience: keep your mixer’s beaters clean and dry for smooth creaming.

Preparation Method

fluffy funfetti cake preparation steps

  1. Preheat your oven to 350°F (175°C). Grease and line your cake pans with parchment paper. This step prevents sticking and ensures an easy release.
  2. In a medium bowl, whisk together the dry ingredients: 2 ½ cups (312 g) all-purpose flour, 2 ½ teaspoons baking powder, and ½ teaspoon salt. Set aside. This dry mix is your foundation, so whisk well to break up lumps.
  3. In a large mixing bowl, cream the butter and sugar: Beat ¾ cup (170 g) softened unsalted butter with 1 ¾ cups (350 g) granulated sugar using an electric mixer on medium speed until light and fluffy, about 3-4 minutes. This step traps air and gives the cake its fluffy texture.
  4. Add eggs one at a time: Beat in 4 large room temperature eggs, one by one, ensuring each is fully incorporated before adding the next. This helps create a smooth batter and prevents curdling.
  5. Mix in vanilla extract: Add 2 teaspoons pure vanilla extract and blend well.
  6. Alternate adding dry ingredients and milk mixture: In a separate bowl, combine 1 cup (240 ml) whole milk and ½ cup (120 g) sour cream. Add the flour mixture and the milk mixture alternately to the butter mixture, starting and ending with the dry ingredients. Mix on low speed just until combined—overmixing can make the cake dense.
  7. Gently fold in the sprinkles: Using a rubber spatula, fold ¾ cup (about 120 g) rainbow sprinkles into the batter. Be gentle to avoid bleeding the colors.
  8. Divide batter evenly between pans: Use a kitchen scale or measuring cups to split the batter equally. Smooth the tops with a spatula.
  9. Bake for 30-35 minutes: Place pans in the oven and bake until a toothpick inserted in the center comes out clean or with just a few crumbs attached. The cakes should spring back lightly when touched.
  10. Cool in pans for 10 minutes: Then transfer to cooling racks to cool completely. This prevents sogginess and makes frosting easier.

Pro tip: If your sprinkles start sinking during baking, try tossing them in a tablespoon of flour before folding into the batter next time. Also, make sure your eggs and dairy are truly at room temperature to keep the batter smooth and airy.

Cooking Tips & Techniques

One golden rule for this fluffy funfetti cake is to avoid overmixing. You know what happens when you overmix? The crumb tightens, and instead of that soft fluffiness, you get a heavier cake. So mix just until you see no streaks of flour.

Another tip? Use room temperature ingredients. Cold eggs or milk can cause the batter to seize and won’t trap air properly. When I first tried this recipe, I ignored this and ended up with a denser cake, so trust me on this one.

Folding in the sprinkles gently is crucial—they add charm and sweetness but can bleed color if handled roughly. Using a rubber spatula and slow, sweeping motions keeps them intact.

Timing-wise, bake the cake in the center rack for even heat distribution. If you have two racks, place the pans side by side on the middle rack rather than one above the other. Also, resist opening the oven door too early — the sudden temperature drop can cause the cake to collapse.

If you want an ultra-moist cake, a light brush of simple syrup on the layers before frosting works wonders. I often do this when making layered cakes for parties.

Variations & Adaptations

  • Gluten-Free Version: Swap the all-purpose flour for a 1:1 gluten-free baking flour blend. I’ve tried Bob’s Red Mill with great results, just add an extra ¼ teaspoon xanthan gum if your blend doesn’t include it.
  • Dairy-Free Adaptation: Use coconut yogurt instead of sour cream and almond or oat milk for the milk. The cake still turns out moist and fluffy – perfect for those with dairy sensitivities.
  • Flavor Twists: Add lemon zest and swap vanilla extract for almond extract for a bright, nutty spin. Or mix in mini chocolate chips with the sprinkles for double the fun.
  • Cooking Methods: This batter works great in cupcake liners too – bake for 18-22 minutes at 350°F (175°C) for colorful funfetti cupcakes.

Personally, I once tried adding crushed freeze-dried strawberries to the batter along with the sprinkles. It added a subtle tartness that balanced the sweetness perfectly and made the cake feel a little more grown-up.

Serving & Storage Suggestions

This fluffy funfetti cake is best served at room temperature, with a simple vanilla buttercream or whipped cream frosting to complement the vanilla base without overpowering it. A light dusting of extra sprinkles on top adds that festive touch.

Pair it with a cold glass of milk, a cup of tea, or even a scoop of vanilla ice cream for a dreamy dessert experience. It’s a showstopper for birthday parties, afternoon tea, or a cozy treat when you just need a little sweet cheer.

To store, wrap the cake tightly in plastic wrap or keep it in an airtight container. It stays fresh at room temperature for up to 2 days, or refrigerated for up to 5 days. For longer storage, freeze the layers wrapped in foil and plastic wrap for up to 3 months.

When reheating slices, warm gently in the microwave for 10-15 seconds to bring back that soft, just-baked feel. Flavors actually develop and meld nicely after a day, so if you can wait, the cake tastes even better the next day.

Nutritional Information & Benefits

This funfetti cake recipe is a treat, but it also uses real ingredients you can recognize—no artificial mixes here. Each slice (assuming 12 slices total) contains roughly 350 calories, 14 grams of fat, 45 grams of carbohydrates, and 4 grams of protein.

The eggs provide some protein and essential nutrients, while the butter adds richness and vitamin A. Using sour cream contributes moisture and a bit of tang, which balances the sweetness without extra sugar.

If you’re watching carbs or prefer a lighter version, you can reduce sugar slightly or try swapping all-purpose flour for almond flour, though this will change the texture. Always be mindful of potential allergens like dairy, eggs, and gluten if serving to sensitive guests.

From a wellness perspective, enjoying a slice of this cake is about joy and celebration, which is just as important as nutrition. It’s a reminder that good food can be fun and nourishing for the soul.

FAQs

Can I use different types of sprinkles for the funfetti cake?

Absolutely! Just pick sprinkles that hold their shape well during baking. Jimmies or nonpareils work best. Avoid very soft or large sprinkles that might bleed color or melt too much.

How do I keep the sprinkles from sinking to the bottom?

Toss your sprinkles in a tablespoon of flour before folding them into the batter. This helps them stay suspended evenly throughout the cake.

Can I make this cake gluten-free?

Yes! Use a 1:1 gluten-free flour blend and add a little xanthan gum if it’s not included. The texture will be slightly different but still tasty and fluffy.

How should I store leftover funfetti cake?

Wrap it tightly in plastic wrap or keep in an airtight container at room temperature for up to 2 days, or refrigerate for up to 5 days. You can also freeze cake layers for up to 3 months.

Is it better to use cake flour or all-purpose flour?

I recommend all-purpose flour for this recipe. It gives a nice structure and fluffiness. Cake flour can make the cake a bit too soft and delicate, which might be tricky when handling layers.
