Gathering the right ingredients is the first step toward creating this show-stopping Funfetti Bundt Cake with Rainbow Sprinkles and White Chocolate Pudding Recipe. Each ingredient plays a crucial role in delivering the perfect balance of flavor, texture, and visual appeal.
- White cake mix: The base of our cake that provides a soft and tender crumb with classic vanilla flavor.
- Instant white chocolate pudding mix (3.4 oz): Adds moisture and a subtle creamy sweetness that makes the cake irresistibly smooth.
- Sour cream or Greek yogurt (1 cup): Adds richness and a slight tang to balance the sweetness while keeping the cake moist.
- Large eggs (4): Essential for structure and richness, helping the cake rise beautifully.
- Canola oil (1/2 cup): Keeps the cake moist without weighing it down.
- Milk (1 cup): Adds liquid to the batter for a smooth consistency and tender crumb.
- Rainbow sprinkles (1/2 to 3/4 cup): The star of the show, these bring vibrant pops of color and fun to every slice.
- Powdered sugar (1 cup): For a simple glaze that adds a sweet finishing touch.
- Milk for glaze (1 tablespoon plus 1 teaspoon): Used to thin out the powdered sugar into a drizzle-ready glaze.
- Additional rainbow sprinkles (1 to 2 tablespoons): To decorate the top and create extra festive appeal.
How to Make Funfetti Bundt Cake with Rainbow Sprinkles and White Chocolate Pudding Recipe
Step 1: Prepare Your Pan and Oven
Preheat your oven to 350 degrees Fahrenheit and generously spray a 12-cup bundt pan with a nonstick baking spray that contains flour. This extra step ensures your beautiful cake releases easily for that perfect presentation.
Step 2: Combine the Batter Ingredients
In a large mixing bowl, combine the white cake mix, instant white chocolate pudding mix, sour cream (or Greek yogurt), eggs, canola oil, and milk. This flavorful mix forms the foundation for your moist and tender cake.
Step 3: Beat Until Smooth
Beat the mixture on low speed for 1 minute to combine ingredients without splashing, then increase to medium speed and beat for 2 minutes until the batter is completely smooth. This step is key for a light texture.
Step 4: Fold in the Rainbow Sprinkles
Gently fold in the rainbow sprinkles with a spatula. Be careful not to overmix as this could cause the sprinkles to bleed their colors into the batter, keeping those bright speckles intact.
Step 5: Bake the Cake
Pour your batter evenly into the prepared bundt pan. Bake for 55 to 60 minutes, or until a toothpick inserted comes out mostly clean with just a few moist crumbs attached—this means it’s perfectly baked.
Step 6: Cool and Release from Pan
Let the cake cool in the pan for 15 minutes to firm up, then carefully invert it onto a serving plate and allow it to cool completely. This step helps avoid any cracks or breakage.
Step 7: Prepare the White Chocolate Glaze
Whisk together the powdered sugar and milk until smooth and pourable. This simple glaze adds a sweet, glossy finish that complements the cake’s richness beautifully.
Step 8: Glaze and Decorate
Spoon or drizzle the glaze over the cooled cake and immediately sprinkle 1 to 2 tablespoons of rainbow sprinkles on top for that joyful, festive final look.
How to Serve Funfetti Bundt Cake with Rainbow Sprinkles and White Chocolate Pudding Recipe

Garnishes
For an extra touch of whimsy, garnish your Funfetti Bundt Cake with a few fresh berries or edible flowers alongside the rainbow sprinkles. A light dusting of powdered sugar or a dollop of whipped cream also adds elegance and extra indulgence.
Side Dishes
This cake pairs wonderfully with a scoop of vanilla ice cream or a cup of rich hot cocoa. A light fruit salad with citrus notes can also balance the sweetness and keep your palate refreshed.
Creative Ways to Present
Present your cake on a colorful cake stand to highlight its festive vibe. For a party, slice the cake into thick wedges and plate with a drizzle of berry sauce or a small bowl of sprinkles for guests to customize their slices.
Make Ahead and Storage
Storing Leftovers
Store leftover Funfetti Bundt Cake covered at room temperature for up to 3 days. Make sure it’s in an airtight container to keep it from drying out while maintaining that delightful moist texture.
Freezing
This cake freezes beautifully. Wrap it tightly in plastic wrap and then foil to avoid freezer burn. It can be frozen for up to 3 months. Thaw overnight in the refrigerator before serving.
Reheating
If you want to serve your cake warm, gently reheat individual slices in the microwave for about 15 to 20 seconds. Avoid overheating, which can dry it out. A slightly warmed slice with a scoop of ice cream is pure bliss.
FAQs
Can I substitute the sour cream with something else?
Yes! Greek yogurt is a fantastic substitute for sour cream. It provides similar moisture and tang without altering the texture or flavor too much.
Do I have to use rainbow sprinkles in the batter?
While not mandatory, rainbow sprinkles add the signature colorful fun to the cake. You can use other types of sprinkles, but avoid ones with a high sugar coating that might bleed too much.
Is it necessary to use instant pudding mix?
The instant white chocolate pudding mix is what makes this cake incredibly moist and tender. Skipping it will lead to a drier cake, so it’s highly recommended to keep for the best results.
Can I make this cake gluten-free?
Yes! Use a gluten-free white cake mix and ensure your pudding mix and other ingredients are gluten-free. The texture will be just as delightful.
How long will the glaze stay fresh on the cake?
The glaze sets quickly but is best enjoyed within the first day. If stored properly, it can keep its fresh look and taste up to 2 days at room temperature.
