How to Make Hot Chocolate Lasagna

Cookie crumbs combined with butter.

Step 2. Stir in melted butter in a small bowl.

Crust mixture spread into baking dish.

Step 3. Press the mixture in the bottom of 13 x 9 baking dish. Place in the fridge or freezer so that it can firm while you make the filling.

Frequently Asked Questions

Can you use Whipped Cream instead of Cool Whip?

Yes, you can use homemade whipped cream instead of the cool whip in this recipe. Just make sure that you whip the cream until stiff peaks form and then mix it with the other ingredients.

How to fix runny pudding?

The quickest way to fix runny pudding is not mix in another packet of the dry ingredients. However, if you do not have another packet on hand then I recommend refrigerating it overnight to thicken the pudding.

Do not mix the pudding into the lasagna until it is thicken or it will ruin that layer.

How to store?

This no bake lasagna will need to be stored covered in the refrigerator for up to 1 week.
You can let it sit at room temperature for around 15-20 minutes when serving but then refrigerate again after that time.

How to freeze?

Yes, you can cover and freeze this dessert for up to 2-3 months. I recommend not adding the marshmallows or chocolate syrup until you are ready to serve.

Defrost the lasagna out overnight in the refrigerator and then it’s ready to serve.

Recipe Tips

  • Make sure to freeze each layer before adding the next to make perfect layers and not cause all the ingredients to mix together. This is the most important step so be patient with making this recipe.
  • This recipe is very versatile so you can easily switch out items that you don’t like with other flavors.
  • Use a plastic knife when cutting to make clean lines when serving. Make sure to clean the knife after each cut for clean slices.
  • This recipe is best if refrigerated over night before serving. This lasagna is perfect to make the night before serving.
  • Make sure that the pudding is mixed until it’s thick or it won’t set properly.

    I make this for potlucks and sometimes have to double it…there is never any left…it is so so good…. if I make it for home I halve the recipe to make a smaller amount or we would eat the whole thing ( just me and dear husband)…
