Tips for Making Chocolate Lasagna
You will want to let each layer set in the fridge for a little bit (about 10-20 minutes). Doing this is what will really give it the layered lasagna look. It’s the most important for the Oreo and melted butter crust layer.
I like to use the food processor to crush the Oreo crust, it really gets them finely mashed up. But, if you don’t have one, no worries! The other option is to put the Oreos in a large Ziploc bag and use a rolling pin to smash them to your desired crumbles!
Try to add different add-ins like M&M's, nuts or look below for some other great ideas.
To store chocolate lasagna in the fridge, cover the dish tightly with plastic wrap or aluminum foil and refrigerate for 3-4 days. For freezing, place in an airtight container or freezer bag, and freeze for up to 2-3 months, thawing in the refrigerator before serving.
