Gather all the ingredients and tools needed for your Cookie Lasagna.

In a large bowl, combine 1 cup of mascarpone cheese, ½ cup of powdered sugar, and 1 teaspoon of vanilla extract. Beat on medium speed for about 3 minutes until smooth.

In another bowl, pour in 1 cup of heavy whipping cream and whisk until soft peaks form, about 2-3 minutes.

Gently fold the whipped cream into the mascarpone mixture using a spatula.

Start layering by placing a single layer of chocolate wafer cookies at the bottom of your serving dish, followed by the mascarpone mixture.

Dust a light layer of cocoa powder over the cream, then repeat layering until the dish is full.

Cover tightly with plastic wrap and chill in the refrigerator for at least 4 hours, or overnight.

Just before serving, drizzle the melted chocolate chips over the top.
