Step 1

Place cookies (cookie and filling) in a large ziplock bag and use a rolling pin to crush the cookies. Place crumbs in a bowl and pour melted butter onto crumbs. Stir until crumbs are evenly moist. Spread crumbs onto a rimmed baking sheet and bake at 350*F for 6-8 minutes. Remove from oven and allow to cool. (Crumbs may appear soft and/or oily when still hot, but will become crisper as they cool).

Step 2

In the bowl of an electric mixer, beat cream until it begins to thicken. Add vanilla and powdered sugar (while mixing) and continue to beat until the cream has more than doubled in volume and when you stop the mixer and lift up the whisk, the cream stays in place. Be careful not to over beat, or the cream will become clumpy and too stiff. Scoop finished whipped cream into a bowl and keep in the fridge as you prepare the remaining layers.

Step 3

In the bowl of an electric mixer (no need to wash if there are small remnants of whipped cream), beat cream cheese until smooth. Add Nutella and blend until fully incorporated. Continue mixing and slowly pour in heavy cream. Beat until the cream is fully incorporated and the mixture has thickened and increase in volume. Add vanilla and powdered sugar (while mixing). Mix until all ingredients are well blended and the mixture is light and fluffy. Place in the refrigerator until ready to assemble desserts (up to 2 hours).

Step 4

Both the whipped cream and the Nutella cream can be placed (separately) in a large piping bag or large ziplock bag for easy (and prettier) layering. You may also simply spoon those elements into the dishes.

Step 5

Slice bananas.

Step 6

Begin assembly by adding a spoonful of oreo crumble to the bottom of each dish. Add a layer of Nutella cream, then a layer of sliced banana. Repeat layers... crumbs, Nutella, bananas. Add a layer of whipped cream and garnish with a slice or two of banana and a few oreo crumbs. Garnish just before serving. If making ahead, the desserts can be store in the refrigerator (without the garnish) for up to 2 hours. Save 1/2 of a banana (in the peel) and slice just before serving.
