Keto No-Bake Oreo Icebox Cake with Dulce de Leche

A decadent no-bake dessert featuring layers of crushed Oreo crust, vanilla-infused whipped topping, and whole cookies that soften into cake-like texture. The dulce de leche drizzle adds rich caramel sweetness while chopped Oreos provide textural contrast. Perfect for summer entertaining or when you need an impressive make-ahead dessert without turning on the oven. The longer it chills, the more the cookies transform into tender, cake-like layers.

Chill 6 hours for some texture or 24 hours for completely smooth, cake-like consistency as cookies soften.
Use a serrated knife for clean slices through the layered cookies and whipped topping.
Good to Know
Refrigerate covered for up to 3 days. Texture becomes increasingly soft over time.
Make 1-2 days ahead for best texture. Assemble completely except final toppings.
Slice with serrated knife for clean cuts. Serve chilled directly from refrigerator.
Common Mistakes

FAQ
Can I make this without a springform pan?
Use a regular 9-inch round pan lined with plastic wrap extending over edges for easy removal. The plastic wrap acts as handles to lift the cake out.
How long does this cake keep in the refrigerator?
Store covered for up to 3 days. The cookies continue softening over time, creating an increasingly cake-like texture rather than distinct layers.
Can I freeze this icebox cake?
Yes, wrap well and freeze up to 1 month. Thaw in refrigerator overnight before serving. Texture may be slightly different after freezing.
