No-Bake Funfetti Oreo Icebox Cake is a layered dessert made with Birthday Cake Oreos dipped in milk, a funfetti-style whipped cream and cream cheese filling, and plenty of rainbow sprinkles. It sets up in the fridge like a soft, sliceable cake with the nostalgic flavor of birthday cake, Oreos, and whipped cream in every bite.
Why this icebox cake works
This recipe follows the same pattern as classic Oreo icebox cakes: cookies briefly dipped in milk are layered with a creamy filling, then chilled until the cookies soften into cake-like layers. The twist here is the funfetti angle—Birthday Cake Oreos, dry cake mix in the whipped cream, and rainbow jimmies—echoing other Funfetti Oreo icebox cake recipes.
