Let the cake cool completely, then invert it over a baking rack on a sheet pan to contain any stray crumbs. Eat this 3-ingredient Oreo cake as-is or top with an optional chocolate ganache.
How to make the ganache
Bring 1/2 cup cup heavy cream to a boil. Place 1/2 cup chopped chocolate or chocolate chips in a heat-safe bowl. Pour the hot heavy cream over the chocolate and whisk the mixture until smooth. Pour the ganache over the cooled Oreo cake, then press crushed Oreos onto the edge of the cake for decoration.
Be sure to allow the Oreo cake to set before digging in!
Turn this into a cookies and cream cake
You already have the Oreo cake as a base. Just make homemade whipped cream, or grab a tub of store-bought whipped topping. Spread the whipped cream on top and sprinkle it with even more crushed Oreos for a dreamy dessert.
