Ingredients
- 1 package Birthday Cake Oreos (about 36 cookies)
- 1 cup milk (for dipping Oreos)
- 2 cups heavy whipping cream
- 1/2 cup confectioners’ sugar
- 1/2 cup dry white cake mix
- 8 oz cream cheese, softened
- 1/3 cup granulated sugar
- 1 teaspoon vanilla extract
- 1/4 cup rainbow sprinkles (use jimmies)
- Extra whipped cream and sprinkles for topping (optional)
This ingredient list matches closely with existing Funfetti Oreo icebox cake recipes that layer Birthday Cake Oreos with a cake-mix whipped cream/cream cheese filling and sprinkles.
Step-by-step instructions
1. Make the funfetti whipped cream
- In a large bowl, whip cold heavy cream to soft peaks.
- Add confectioners’ sugar and dry white cake mix.
- Continue whipping until stiff peaks form.
Oreo icebox cake recipes commonly use stabilized whipped cream (sometimes with powdered sugar or instant pudding mix), and funfetti versions often add dry cake mix for flavor.
- Gently fold in the rainbow sprinkles (jimmies) so they’re evenly distributed without overmixing. Recipes advise using jimmies because nonpareils can bleed color into the cream.
2. Make the cream cheese layer
- In another bowl, beat softened cream cheese with granulated sugar and vanilla extract until completely smooth and creamy.
- Fold the whipped funfetti cream into the cream cheese mixture until fully combined and fluffy.
Many Oreo icebox cakes combine cream cheese with whipped cream for a thicker, mousse-like filling that slices well.
3. Layer the icebox cake
- Lightly grease a 9-inch springform pan.
- Spread a small amount of the cream mixture over the bottom of the pan; this helps anchor the first Oreo layer.
- Pour the milk into a shallow dish. Quickly dip each Oreo in the milk for 1–2 seconds—just enough to soften the surface without making them soggy, a standard tip in Oreo icebox cake methods.
- Arrange a single layer of milk-dipped Oreos over the base.
- Spread about 1/3 of the cream mixture over the cookies, smoothing to the edges.
- Repeat layering: dipped Oreos, then cream, two more times, ending with cream on top (three cream layers total).
This layering pattern matches Funfetti Oreo icebox cake and general Oreo icebox cake instructions—Oreos + cream in repeating layers, finishing with cream.
4. Chill and set
- Cover the pan tightly with plastic wrap or foil.
- Refrigerate for at least 4–6 hours, preferably overnight. Icebox cake recipes consistently recommend an overnight chill so the cookies soften fully and the dessert slices like cake.
5. Decorate and serve
- Just before serving, release the springform ring and smooth edges if needed.
- Decorate the top with extra whipped cream swirls and more rainbow sprinkles if desired. Funfetti and birthday cake icebox cakes often add sprinkles last for maximum color impact.
- Slice with a sharp knife and serve chilled.
