Ingredients

For the Cake

1 white cake mix
1 (3.4 ounce) box instant white chocolate pudding mix
1 cup sour cream (or Greek yogurt)
4 large eggs
½ cup canola oil
1 cup milk
½ to ¾ cup rainbow sprinkles

For the Topping

1 cup powdered sugar
1 tablespoon plus 1 teaspoon milk
1 to 2 tablespoons rainbow sprinkles

Step-by-Step Instructions

Preparing the Ingredients

Preheat your oven to 350°F. Then spray a 12-cup bundt pan with nonstick baking spray that contains flour. This step prevents sticking and helps the cake release cleanly.

Next, gather all measured ingredients before mixing. Combine the white cake mix and dry pudding mix in a large bowl. Add sour cream, eggs, oil, and milk. Starting with room temperature eggs helps the batter blend smoothly. Because organization speeds up baking, preparing everything first makes the process effortless.

Cooking Instructions

Beat the mixture on low speed for one minute to combine. Then increase to medium speed and beat for two additional minutes until smooth and thick. Gently fold in the rainbow sprinkles using a rubber spatula. Stir carefully so the colors stay vibrant.

Pour the batter evenly into the prepared bundt pan. Bake for 55 to 60 minutes. Check doneness by inserting a toothpick into the center; it should come out mostly clean. After baking, let the cake cool in the pan for 15 minutes. Then invert it onto a serving plate and allow it to cool completely.

To finish, whisk powdered sugar with milk until smooth. Spoon the glaze over the top, allowing it to drizzle naturally down the sides. Sprinkle extra decorations over the glaze and let it set before slicing.

Tips for Perfect Results

Common Mistakes to Avoid

First, avoid overmixing the batter. Although you need to beat it well at the start, excessive mixing after adding sprinkles can cause color bleeding. Also, always use a baking spray that includes flour. Regular spray may lead to sticking, especially with bundt pans that have detailed designs.

Additionally, resist removing the cake too early. If you invert it immediately after baking, it may break apart. Instead, allow it to rest for 15 minutes so the structure firms up.

Pro Tips for Better Flavor

If you prefer a stronger cake batter flavor, add ½ teaspoon vanilla extract and ½ teaspoon almond extract. This small adjustment deepens the aroma without overpowering the sweetness.

For a richer presentation, replace the simple glaze with creamy vanilla frosting along the sides. You can also drizzle melted chocolate and white chocolate over the top for extra contrast. These additions transform Funfetti Bundt Cake into a bakery-style centerpiece while keeping preparation simple.

Serving and Storage

How to Serve

Serve Funfetti Bundt Cake slightly chilled or at room temperature. Because the glaze sets beautifully, each slice cuts cleanly and reveals the vibrant sprinkle pattern inside. Pair it with coffee, milk, or vanilla ice cream for a complete dessert experience.

For themed gatherings, coordinate sprinkle colors with the occasion. Blue and pink suit baby showers, while red and green work perfectly for Christmas celebrations. This flexibility makes the cake a dependable choice for any event.

How to Store Leftovers

Store leftover cake in an airtight container at room temperature for up to three days. If your kitchen runs warm, refrigerate it instead. Before serving chilled slices, let them sit at room temperature for 20 minutes to soften.

You can also freeze unfrosted slices individually wrapped in plastic. Thaw overnight in the refrigerator, then glaze before serving for the freshest appearance.

Conclusion

Funfetti Bundt Cake combines convenience, flavor, and festive color in one effortless recipe. Because it relies on simple ingredients and clear steps, it works for beginners and experienced bakers alike. The moist crumb, sweet glaze, and cheerful sprinkles guarantee smiles at every celebration. Bake this cake once, and it will quickly earn a permanent place in your dessert rotation.

Frequently Asked Questions

Can I use Greek yogurt instead of sour cream?

Yes. Greek yogurt substitutes perfectly for sour cream in equal amounts. It provides similar moisture and slight tang while maintaining the cake’s tender texture.

Do sprinkles melt during baking?

Quality jimmies-style sprinkles hold their shape well in the oven. Avoid nonpareils because they bleed color more easily and may discolor the batter.

Can I make this cake ahead of time?

Absolutely. Bake the cake one day in advance and store it covered at room temperature. Add the glaze shortly before serving for the freshest presentation.
