Line Your Cake Pan: Use an 8 or 9-inch round pan and line it with plastic wrap, letting the ends hang over the edges. This makes removing the cake much easier once it’s frozen solid. Want to skip the lifting? A springform pan is a great swap, it opens up easily and helps your cake keep a nice shape. Either choice gives you a smooth start.

Soften the First Ice Cream Flavor: Take the first container of ice cream out of the freezer and let it rest at room temperature for 10–15 minutes. You want it soft enough to spread but still thick. Spoon it into the bottom of your lined pan and spread it out evenly with a spatula. Make sure the layer is smooth and level. Place it in the freezer for 30–45 minutes so it firms up properly.

Add a Crunch or Cake Layer: Time to build in some texture. You can crush cookies like Oreos or graham crackers and press them gently into the first ice cream layer. Prefer cake? Bake a thin sponge, trim it to fit the pan, and lay it over the frozen ice cream. Return the pan to the freezer for about 15 minutes so everything sets.

Add the Second Ice Cream Layer: Take your second ice cream flavor out and let it soften just like the first. Once it’s spreadable, layer it evenly over the cookie or cake base. Use your spatula to smooth it out nicely. Pop the cake back into the freezer for at least 1 hour to lock in the structure.

Top and Decorate: Once the cake is solid, it’s time to dress it up. Coat the top and sides with whipped topping, store-bought or homemade, whichever you like. Then add your personal touch: toss on some sprinkles, drizzle chocolate or caramel, or gently press crushed nuts around the sides. Once decorated, put the cake back in the freezer for at least an hour to firm everything up.

Slice and Serve: Ready to serve? Gently lift the cake out using the plastic wrap and set it on a cutting board. To get clean, easy slices, warm your knife by running it under hot water before you cut. This helps the blade glide through smoothly. Serve it up right away and enjoy each cold, creamy bite.
