Oreo Crumble Cake

This frozen Oreo cake is built in three indulgent layers: crushed Oreo cookies on the bottom, a rich chocolate-pecan fudge layer in the middle, and whipped vanilla ice cream on top. It’s an ice cream cake without any actual cake, and it’s all the better for it.

The fudge layer is the anchor. Melted chocolate chips and margarine get tempered into beaten eggs (adding a little at a time to warm the eggs without scrambling them), then cooked briefly. Powdered sugar and pecans fold in to create a dense, fudgy spread that sets up firm in the freezer, giving the dessert structure between the crunchy cookie base and the soft ice cream top.

Whipping the softened ice cream before spreading it over the frozen chocolate layer incorporates air and makes it easier to spread into an even layer. The whole thing freezes solid and slices cleanly after sitting out for about 15 minutes.

Kitchen Tips

• Crush the Oreos in a sealed plastic bag with a rolling pin. You want crumbs, not dust. Some slightly larger pieces add texture to the base.
• Temper the eggs carefully. Pour a small amount of the hot chocolate mixture into the beaten eggs first, whisking constantly. This prevents scrambled eggs in your fudge layer.
• Freeze the chocolate layer until hard before adding the ice cream. If it’s still soft, the layers will mix instead of staying distinct.
• Pull from freezer 15 minutes before serving. A rock-hard frozen cake is impossible to cut cleanly. That brief rest makes slicing easy.

Variations

• Mint chocolate chip ice cream instead of vanilla for a cookies-and-cream-meets-mint combination.
• Peanut butter drizzle: Warm peanut butter thinned with a little cream and drizzle over the ice cream layer before the final freeze.
• Use chocolate ice cream for a triple-chocolate version that’s extremely rich.
