You can use any 9×13-inch pan that you like for this recipe. If you want your chocolate lasagna to be extra thick, you can also make it in a 9 or 10-inch square pan.
Regular Oreos work best.While double stuff Oreos are amazing dunked in milk, they have a bit too much frosting in them when it comes to making a crispy cookie crust.
Use peppermint extract.I prefer peppermint extract over the other variety, called “pure mint” extract. Peppermint has a lighter flavor, whereas the other is more herbal.
Be sure to use instant pudding mix.When buying pudding mix, look for the box that says “instant”. The type of pudding mix that needs to be cooked won’t work properly here.
You need a total of 16 ounces of whipped topping. Half goes into the mint layer, and the other half is for the topping. It’s usually less expensive to buy the larger container than it is to buy 2 8-ounce containers.
To use fresh whipped creaminstead of whipped topping: Whip two cups of heavy cream to get 16oz. Of whipped cream and divide in half for the different layers.
Chill each layer!The key to making a layered dessert with clean lines is that each layer is cold and set firm before you add the next one. A little bit of patience makes all the difference here.
To Store:Keep chocolate lasagna covered in the fridge for up to 5 days. You can also freeze the dessert for up to 2 months. Just allow it to thaw overnight in the fridge before serving.
