Ingredients & Preparation

Making Funfetti cake from scratch is easier than it looks. The magic comes from a blend of everyday baking staples combined with sour cream for moisture and sprinkles for color. Below, you’ll find everything you need to get started, plus a few prep tips that guarantee success.

Funfetti Cake Ingredients

Ingredient	Amount
All-purpose flour	2 ½ cups
Granulated sugar	1 ½ cups
Baking powder	2 ½ tsp
Salt	½ tsp
Unsalted butter, softened	½ cup
Vegetable oil	¼ cup
Eggs	4 large
Whole milk	1 cup
Sour cream	½ cup
Vanilla extract	1 tbsp
Almond extract (optional)	½ tsp
Rainbow jimmies sprinkles	¾ cup

This ingredient lineup gives the cake its soft crumb, rich vanilla taste, and perfect rise. The combination of butter + oil keeps the texture light yet moist, while the sour cream makes every bite tender.

Buttercream Frosting Ingredients

Ingredient	Amount
Unsalted butter, softened	1 cup
Powdered sugar	4 cups
Heavy cream or milk	2–3 tbsp
Vanilla extract	1 tbsp
Pinch of salt	Optional

This frosting is silky, stable, and spreads beautifully across the cake layers. If you prefer a lighter frosting, you can whip it longer to make it more airy.

Prep Steps Before Baking

Before you start mixing, proper preparation ensures your Funfetti cake turns out fluffy and picture-perfect. Here’s what to do:

• Preheat your oven to 350°F (177°C).
• Grease two 8-inch round cake pans, then add a light dusting of flour or line them with parchment circles.
• Bring butter, eggs, and milk to room temperature for smoother mixing.
• Measure flour correctly by spooning it into a measuring cup and leveling it off.
• Choose rainbow jimmies, not nonpareils, to prevent color bleeding.
• Set your sprinkles aside so you can fold them in gently at the end.

Taking a few minutes to prep properly gives your cake the best texture and rise.

How to Make Funfetti Cake

Now comes the fun part—mixing your batter and creating those festive, colorful layers everyone loves. This section walks you through every step with clarity, so your cake comes out perfect on the first try.

Step-by-Step Cake Instructions

Here’s how to make the most delicious, moist Funfetti cake:

1. Combine dry ingredients
   In a large bowl, whisk the flour, baking powder, and salt until well blended.
2. Cream butter and sugar
   In another bowl, beat the softened butter and sugar together for 3 minutes until pale and fluffy. This helps trap air, giving your cake a light texture.
3. Add oil
   Mix in the vegetable oil for additional moisture.
4. Add eggs one at a time
   Mix well after each egg to ensure everything comes together smoothly.
5. Add extracts
   Add vanilla—and almond extract if using—for a strong, bakery-style flavor.
6. Add sour cream
   This ingredient is key for moisture and tenderness.
7. Alternate wet and dry
   Add half the dry ingredients, then the milk, then the rest of the dry ingredients. Mix on low speed to avoid overmixing.
8. Fold in sprinkles
   Gently fold with a spatula so the colors don’t streak.
9. Pour and bake
   Divide the batter evenly into the pans and bake 25–30 minutes until a toothpick comes out clean.
10. Cool completely
    Let cool 10 minutes in the pans, then transfer to wire racks.

Once cooled, your cake is ready for frosting.

Buttercream Frosting Instructions

1. Beat the softened butter until creamy and smooth.
2. Add powdered sugar gradually while mixing on low.
3. Increase speed to medium-high and beat for 2 minutes.
4. Add vanilla and 2 tbsp cream.
5. Beat again until the frosting is light and fluffy.
6. Adjust texture with more cream if needed.

Spread a generous layer between each cake layer, then cover the outside with a smooth finish or rustic swirl.

Tips for a Perfect Funfetti Cake

• Use jimmies sprinkles only — they keep their shape and color.
• Avoid overmixing the batter after adding flour to prevent a dense cake.
• Make sure all ingredients are room temperature for the smoothest batter.
• Level your cakes with a serrated knife for professional-looking layers.
• If making cupcakes, bake for 16–18 minutes.
• Add sprinkles to the frosting for even more color and fun.

❓ FAQ

What kind of sprinkles should I use?

Use rainbow jimmies—they keep their color, don’t melt, and create the classic Funfetti look.

Why did my sprinkles sink to the bottom?

This happens when batter is too thin. Make sure to use full-fat dairy and fold the sprinkles in lightly.

Can I make the cake ahead of time?

Yes! Bake layers, wrap tightly, refrigerate 3 days or freeze 2 months.

Can I use buttermilk instead of milk?

Absolutely—it makes the cake even more tender.

Yes, pour into a 9×13 pan and bake for 30–35 minutes.
