What Ingredients You Will Need

This creamy funfetti layer cake with vanilla buttercream frosting relies on straightforward, pantry-friendly ingredients that come together beautifully. Each ingredient plays its part to create a tender crumb and luscious frosting.

• For the Cake Batter:
  • All-purpose flour – 2 ½ cups (312 grams), sifted for lightness
  • Baking powder – 2 ½ teaspoons (10 grams), to help the cake rise just right
  • Salt – ½ teaspoon (3 grams), balances the sweetness
  • Unsalted butter – 1 cup (227 grams), softened to room temperature for creaminess (I prefer Land O’Lakes for consistent texture)
  • Granulated sugar – 1 ¾ cups (350 grams), for sweetness
  • Large eggs – 4, room temperature, which helps with emulsification
  • Pure vanilla extract – 1 tablespoon (15 ml), for that signature vanilla warmth
  • Whole milk – 1 cup (240 ml), at room temperature to keep the batter smooth
  • Rainbow sprinkles – ½ cup (90 grams), use small, firm sprinkles (avoid jimmies as they bleed color into the batter)
• For the Vanilla Buttercream Frosting:
  • Unsalted butter – 1 cup (227 grams), softened (again, Land O’Lakes works great)
  • Powdered sugar – 4 cups (480 grams), sifted to avoid lumps
  • Heavy cream – 2–3 tablespoons (30-45 ml), for that creamy, spreadable texture
  • Pure vanilla extract – 2 teaspoons (10 ml), for flavor depth
  • Pinch of salt, to balance the sweetness

If you want to make it dairy-free, swap the butter with a plant-based alternative and use coconut milk instead of heavy cream. For gluten-free options, almond or oat flour blends can work, but expect a slightly denser crumb.

Equipment Needed

• Two 8-inch (20 cm) round cake pans – non-stick or well-greased for easy release
• Electric mixer – either handheld or stand mixer, essential for whipping the buttercream to the perfect texture
• Mixing bowls – preferably medium to large size for the batter and frosting
• Measuring cups and spoons – precise measurements help keep the cake consistent
• Rubber spatula – for folding in sprinkles and scraping bowl sides
• Cooling racks – important for letting the cakes cool evenly so frosting doesn’t melt
• Cake leveler or serrated knife – to trim cake layers evenly (optional but helpful)

If you don’t have two cake pans, you can bake the layers one at a time, though it takes longer. For frosting, a sturdy bowl and a good whisk can work in a pinch, but the electric mixer definitely saves time and effort. I’ve tried this with various mixers and found that a stand mixer with a paddle attachment gives the smoothest results without overworking the batter or frosting.

Preparation Method

1. Preheat your oven to 350°F (177°C). Grease and flour two 8-inch (20 cm) round cake pans, or line them with parchment paper for extra insurance against sticking. Set aside.
2. Mix dry ingredients: In a medium bowl, whisk together 2 ½ cups (312 grams) all-purpose flour, 2 ½ teaspoons (10 grams) baking powder, and ½ teaspoon (3 grams) salt. This ensures the leavening and salt are evenly distributed.
3. Cream butter and sugar: In a large bowl, beat 1 cup (227 grams) softened unsalted butter with 1 ¾ cups (350 grams) granulated sugar on medium-high speed until light and fluffy, about 3-4 minutes. The mixture should look pale and airy — this is key for a tender crumb.
4. Add eggs and vanilla: One at a time, beat in 4 large eggs (room temperature), mixing well after each addition. Then add 1 tablespoon (15 ml) pure vanilla extract. The batter might look a bit curdled here; that’s normal.
5. Alternate adding dry ingredients and milk: Reduce mixer speed to low. Add the dry ingredients in three additions, alternating with 1 cup (240 ml) whole milk (room temperature), starting and ending with the dry ingredients. Mix just until combined—overmixing can lead to a dense cake.
6. Fold in sprinkles: Gently fold in ½ cup (90 grams) rainbow sprinkles with a rubber spatula. Be careful not to overmix, or the colors may bleed and turn the batter pastel.
7. Divide batter and bake: Evenly pour the batter into the prepared pans and smooth the tops. Bake for 25-30 minutes, or until a toothpick inserted in the center comes out clean. Rotate pans halfway through baking for even browning.
8. Cool completely: Let the cakes cool in the pans for 10 minutes, then run a knife around the edges and transfer to cooling racks. It’s important the layers are completely cool before frosting.
9. Prepare the frosting: Beat 1 cup (227 grams) softened unsalted butter on medium speed until creamy, about 2 minutes. Gradually add 4 cups (480 grams) sifted powdered sugar, mixing on low speed after each addition. Add 2-3 tablespoons (30-45 ml) heavy cream, 2 teaspoons (10 ml) vanilla extract, and a pinch of salt. Beat on high for 3-4 minutes until light, fluffy, and spreadable.
10. Assemble the cake: If needed, level the cakes with a serrated knife. Place one layer on a serving plate, spread about ¾ cup (180 grams) of frosting evenly on top. Add the second layer and frost the top and sides with remaining buttercream. Smooth with an offset spatula or create swirls for a fun look.
11. Chill and serve: For clean slices, refrigerate the cake for at least 30 minutes before slicing. Bring to room temperature 15 minutes before serving.

Pro tip: If your frosting feels too soft, pop it in the fridge for 10 minutes and whip again before spreading. The texture should be creamy but hold its shape.

Cooking Tips & Techniques

One trick I learned early on is how important it is to have all the wet ingredients at room temperature. Cold eggs or milk can cause the batter to seize or curdle, which affects the crumb. Also, folding in the sprinkles gently keeps the colors vibrant rather than muddy.

A common mistake is overmixing the batter once the flour is added. That can make the cake dense and tough — honestly, it’s tempting to keep mixing, but try to stop as soon as everything is combined. The cake should look smooth, not glossy.

When frosting, don’t rush the buttercream. Whip it long enough to get that fluffy, silky texture. If it feels grainy, adding a splash more cream and beating a bit longer usually fixes it. And if you want those perfectly smooth sides, chilling the cake after a crumb coat is a lifesaver.

Multitasking tip: Bake your layers one pan at a time if needed, but don’t skip cooling on racks. I’ve learned the hard way that frosting warm cake melts the buttercream, turning your masterpiece into a sticky mess.

Lastly, using a serrated knife to level the cakes before frosting makes a huge difference in presentation and stability. It’s a small step that pays off.

Variations & Adaptations

This creamy funfetti layer cake with vanilla buttercream frosting is a fantastic canvas for playing around.

• Flavor twist: Add almond extract (1 teaspoon) to the batter for a nutty note, or a teaspoon of lemon zest for a fresh zing.
• Dietary adjustments: Swap regular all-purpose flour with a gluten-free blend. For vegan options, replace eggs with flax eggs and use vegan butter and non-dairy milk for the frosting.
• Seasonal spins: Fold in fresh berries or chopped strawberries along with the sprinkles for a fruity surprise. Or try mini chocolate chips if you’re feeling indulgent.
• Frosting alternatives: Cream cheese frosting adds a tangy contrast, especially if you like a bit of balance against the sweet cake layers.

Personally, I once tried adding a pinch of cinnamon to the batter — the warmth it gave was subtle but irresistible. It’s fun to experiment while keeping the core creamy vanilla feel intact.

Serving & Storage Suggestions

This cake is best served at room temperature, allowing the buttercream to be soft and luscious. It pairs wonderfully with a simple glass of cold milk or a cup of hot coffee. For a festive touch, add fresh fruit on the side or a sprinkle of extra rainbow sprinkles on the plate.

Store the cake covered in the refrigerator for up to 4 days. I recommend bringing it back to room temperature before serving to enjoy that creamy texture fully. If you need to freeze, wrap the frosted cake tightly in plastic wrap and foil for up to 2 months. Thaw overnight in the fridge, then rest at room temp before slicing.

Over time, the flavors meld and the cake becomes even more moist. Leftovers, if you’re lucky to have any, taste almost as good the next day — sometimes better!

Nutritional Information & Benefits
