A no-bake Oreo lasagna with layers of buttery cookie crust, fluffy cream cheese, rich chocolate pudding, and whipped topping. It mixes up quickly and chills to clean, sliceable squares perfect for any occasion.
Double the recipe for a crowd or make half in an 8x8 pan. Refrigerate tightly covered up to 4 days, or freeze up to 1 month and thaw in the fridge. For best structure, use regular Oreos and cold milk; soften cream cheese to avoid lumps. Add final cookie crumbs just before serving for extra crunch. Variations: mint (mint Oreos, peppermint extract), peanut butter cup, mocha, cookies and cream, gluten-free cookies, lighter dairy swaps.
