Step-by-step assembly: how to build the lasagna
- Process whole Oreos with filling into fine crumbs. Mix crumbs with melted butter until evenly moistened.
- Press the cookie mixture firmly into the bottom of a 13 x 9-inch pan. Chill to set while you prepare the next layer.
- Beat the softened butter and cream cheese until smooth. Add powdered sugar and vanilla and beat again until creamy.
- In a separate bowl, whip the heavy cream with the instant hot chocolate powder until it forms stiff peaks.
- Gently fold the whipped hot chocolate cream into the cream cheese mixture until uniform. Spread this mousse over the chilled crust and return to the fridge to firm slightly.
- Whisk the instant pudding mixes with cold milk until it thickens. Fold in the mini marshmallows and spread the pudding over the mousse layer.
- Whip the remaining heavy cream with powdered sugar until stiff peaks form. Spread or pipe the whipped cream over the pudding.
- Chill the assembled pan for several hours or overnight so layers set and flavors meld.
- Just before serving, scatter the remaining mini marshmallows and drizzle with chocolate sauce or Nutella.
- Store leftovers covered in the refrigerator.
Practical tips to get perfect layers every time
- Firm crust: Use a flat-bottomed measuring cup to press crumbs for an even base.
- Cold bowls: Chill your mixing bowl for whipping cream to speed up peak formation.
- Folding: Use gentle folds when combining whipped components to keep the mousse light.
- Chill time: Overnight refrigeration gives cleaner slices and better texture.
- Substitutions: Use store-bought whipped topping if you need a faster option.
