No-Bake Funfetti Oreo Icebox Cake Recipe

Why You’ll Love This Recipe

I love this recipe because it’s easy, fun, and completely no-bake—ideal for when I don’t want to turn on the oven. The combination of cream cheese, whipped cream, and cake mix gives it that signature cake batter flavor, while the Oreos soften into the perfect cookie layer after chilling. It’s a make-ahead dessert that’s creamy, light, and bursting with sweet birthday cake flavor in every bite.

Ingredients

(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)

1 package Birthday Cake Oreos (about 36 cookies)
1 cup milk (for dipping Oreos)
2 cups heavy whipping cream
½ cup confectioners’ sugar
½ cup dry white cake mix
8 oz cream cheese, softened
⅓ cup granulated sugar
1 teaspoon vanilla extract
¼ cup rainbow sprinkles (use jimmies)
Extra whipped cream and sprinkles for topping (optional)

Directions

1. Prepare the whipped cream mixture: I start by whipping the heavy cream in a large bowl until soft peaks form. Then I add the confectioners’ sugar and dry cake mix and continue whipping until stiff peaks form. I gently fold in the rainbow sprinkles and set it aside.

2. Make the cream cheese layer: In another mixing bowl, I beat the softened cream cheese with the granulated sugar and vanilla until smooth and creamy. Then I fold in the whipped cream mixture until it’s fully combined and fluffy.

3. Assemble the cake: I lightly grease a 9-inch springform pan and spread a small amount of the cream mixture on the bottom. I quickly dip each Oreo in milk (for 1–2 seconds) and arrange a single layer over the base. I spread one-third of the cream mixture over the cookies. I repeat this layering two more times, finishing with a layer of cream on top.

4. Chill: I cover the pan with plastic wrap and refrigerate the cake for at least 4–6 hours, but I prefer overnight so the cookies soften into a cake-like texture.

5. Decorate and serve: Before serving, I top the cake with extra whipped cream and a generous sprinkle of rainbow jimmies for that festive finish. Then I slice and serve it chilled.

Servings and timing

This recipe makes about 10 servings and takes 20 minutes to prepare plus 4–6 hours of chilling time (or overnight for best results). It’s a great dessert for birthdays, summer parties, or any event where I want to impress without the stress.

Variations

• I sometimes swap Birthday Cake Oreos for Golden Oreos and add a teaspoon of almond extract for a softer, cake-like flavor.

• For extra color, I mix different types of sprinkles or even mini M&Ms into the cream layer.

• If I’m out of heavy cream, I use Cool Whip instead for a quick shortcut.

• For a chocolate twist, I add a drizzle of chocolate syrup between layers or use chocolate Oreos.

• When I want a little tang, I fold in a spoonful of lemon zest—it gives a fresh contrast to the sweetness.

Storage/Reheating

I store the icebox cake covered in the refrigerator for up to 3 days. It stays soft and creamy, and the flavors continue to develop as it chills. To freeze, I wrap it tightly in plastic wrap and foil, then freeze for up to 1 month. When ready to enjoy, I let it thaw in the fridge overnight before serving.

FAQs

Can I use regular Oreos instead of Birthday Cake Oreos?

Yes! I just use standard Oreos and add a bit more dry cake mix or a dash of cake batter extract to enhance the flavor.

How long should the cake chill?

At least 4–6 hours, but overnight chilling gives the best texture and flavor.

Can I make this in a different dish?

Definitely. A 9×13-inch baking dish works great if I don’t have a springform pan—it just makes slicing a little easier.

How do I prevent the sprinkles from bleeding color?

I always use jimmies (the long, thin sprinkles) instead of nonpareils, which can bleed into the cream mixture.

Can I make this dessert ahead of time?

Yes, it’s perfect for making a day in advance since the flavors meld beautifully as it chills.

Conclusion

I love how this No-Bake Funfetti Oreo Icebox Cake combines all the fun and flavor of a birthday celebration in one effortless dessert. The layers of soft Oreos, creamy cake batter filling, and colorful sprinkles make it as beautiful as it is delicious. Whether I’m celebrating a special occasion or just craving something sweet, this recipe always adds a touch of joy to the table—no oven required.
