Ingredients

  

• Dry ingredients: 2 3/4 cups cake flour (spooned and leveled)
• 1 1/2 cups granulated sugar
• 2 1/2 teaspoons baking powder
• 1/2 teaspoon baking soda
• 1/2 teaspoon fine sea salt
• Wet ingredients: 3/4 cup unsalted butter, softened to room temperature
• 3 large eggs, room temperature
• 2 large egg whites, room temperature
• 1 cup buttermilk, room temperature
• 1/3 cup neutral oil (like canola or vegetable)
• 2 teaspoons pure vanilla extract
• 1/4 teaspoon almond extract (optional but recommended)
• Sprinkles: 3/4 cup rainbow jimmies (not nonpareils)
• Vanilla sprinkle frosting: 1 cup unsalted butter, softened
• 4 cups powdered sugar, sifted
• 1/4 cup heavy cream (plus 1–2 tablespoons more if needed)
• 2 teaspoons pure vanilla extract
• Pinch of salt
• Extra sprinkles for decorating
• Tools: Two or three 8-inch round cake pans
• Electric mixer (hand or stand)
• Offset spatula or butter knife
• Parchment paper and nonstick spray
• Cooling racks

Method

 

1. Prep the pans and oven: Preheat to 350°F (175°C). Grease two or three 8-inch pans, line the bottoms with parchment, then grease again and lightly flour.

   Set aside.

2. Whisk dry ingredients: In a medium bowl, whisk cake flour, baking powder, baking soda, and salt. Set aside.
3. Cream the butter and sugar: In a large bowl, beat butter and granulated sugar on medium-high until pale and fluffy, about 3 minutes. This traps air for a light crumb.
4. Add eggs and whites: Beat in eggs one at a time, then add egg whites, mixing well after each.

   Scrape the bowl. Stir in vanilla and almond extract.

5. Add oil and buttermilk: Mix in the oil until glossy. On low speed, add the dry ingredients in 3 parts, alternating with buttermilk in 2 parts, beginning and ending with dry.

   Mix just until combined. Do not overmix.

6. Fold in sprinkles: Gently fold in 3/4 cup rainbow jimmies with a spatula. Keep the mixing brief to prevent color bleed.
7. Divide and bake: Divide batter evenly between pans.

   Smooth tops. Bake 22–28 minutes (for three pans) or 28–34 minutes (for two pans), until a toothpick comes out clean or with a few moist crumbs.

8. Cool completely: Let cakes cool in pans 10 minutes, then turn out onto racks, peel off parchment, and cool fully. Chilling layers for 30–60 minutes makes frosting easier.
9. Make the frosting: Beat butter until creamy, about 1 minute.

   Add half the powdered sugar and a pinch of salt; beat on low, then medium. Add remaining sugar, vanilla, and 1/4 cup cream. Beat until fluffy, 2–3 minutes.

   Adjust with an extra tablespoon or two of cream for a smooth, spreadable texture.

10. Assemble: Place the first layer on a cake board or plate. Spread an even layer of frosting. Add the next layer(s) and repeat.

    Apply a thin crumb coat around the sides and top. Chill 15 minutes to set.

11. Finish and decorate: Frost the cake generously, smoothing with an offset spatula. Press extra sprinkles around the base and scatter more over the top.

    Add candles for the big moment.

Why This Is Good for You

• Celebration and connection: A homemade cake turns a birthday into a memory. Baking together teaches kids measuring, patience, and creativity.
• Balanced sweetness: The frosting is creamy without being cloying, so a small slice satisfies.
• Customizable ingredients: You control the quality—pure vanilla, real butter, and just the right amount of sugar.
• Confidence booster: This recipe is straightforward and forgiving, which makes home bakers feel capable and excited to try more.

Pitfalls to Watch Out For

• Overmixing the batter: This can make the cake dense. Stop mixing as soon as the flour disappears.
• Using the wrong sprinkles: Nonpareils bleed easily and turn the batter gray.Stick with jimmies.
• Cold ingredients: Cold eggs and butter don’t blend well. Room temperature ingredients create a smoother batter and better rise.
• Overbaking: Dry cake happens fast. Start checking a few minutes early.
• Skipping the crumb coat: Without it, crumbs can drag through the final layer of frosting.

Alternatives

• Gluten-free: Use a 1:1 gluten-free baking flour that includes xanthan gum.Let the batter rest 10 minutes before baking.
• Dairy-free: Swap butter for a quality dairy-free baking stick and use unsweetened almond milk with 1 tablespoon lemon juice in place of buttermilk. Use a dairy-free frosting alternative.
• Chocolate version: Replace 1/2 cup of cake flour with 1/2 cup unsweetened cocoa powder and add an extra 2 tablespoons of buttermilk.
• Confetti cupcakes: Bake in lined muffin tins at 350°F (175°C) for 18–22 minutes. Yields about 24 cupcakes.
• Flavor twist: Add 1 teaspoon lemon zest for a bright note, or swap almond extract for 1/2 teaspoon butter extract for a bakery-style taste.

FAQ

Can I make this cake the day before?

Yes.

Bake and cool the layers, wrap tightly, and keep at room temperature overnight or refrigerate. Frost the next day, or fully assemble and keep covered in the fridge. Bring to room temp before serving.

What if I don’t have cake flour?

Use all-purpose flour and replace 2 tablespoons per cup with cornstarch (for this recipe: measure 2 3/4 cups all-purpose flour, remove 5 1/2 tablespoons, and add 5 1/2 tablespoons cornstarch).

Sift well.

How do I prevent domed tops?

Bake-even strips help. Or level gently with a serrated knife after cooling. Avoid overfilling pans and keep oven temperature accurate with an oven thermometer.

Which sprinkles work best?

Rainbow jimmies hold their color in batter.

Avoid nonpareils (the tiny balls), which tend to bleed and streak.

Can I reduce the sugar in the frosting?

You can cut 1/2 cup and add a splash more cream for texture, but too little sugar will affect structure. Taste as you go to find the right balance.

How do I get smooth frosting without air bubbles?

Beat on low at the end for 30–60 seconds to push out air. Use an offset spatula warmed briefly in hot water (wipe dry) for silky finishes.

Can I bake this in a 9×13-inch pan?

Yes.

Pour the batter into a greased and lined 9×13-inch pan and bake 30–38 minutes, until a toothpick comes out clean. Frost the top and shower with sprinkles.
