Ingredients

Chocolate Cookie & Chip Crunch Base

 1 ½ cups Oreos or dark chocolate cookies, finely crushed

 3 tbsp unsalted butter, melted

 ½ cup mini semi-sweet chocolate chips

Silky Chocolate Mousse

 6 oz semi-sweet or dark chocolate (50–70%), finely chopped

 1 ¾ cups heavy whipping cream, cold (divided: ¼ cup heated, 1 ½ cups whipped)

 3 tbsp powdered sugar

 1 tsp vanilla extract

 1 pinch espresso powder or instant coffee (optional, enhances chocolate flavor)

Topping & Garnish

 ½ cup heavy cream + 1 tbsp powdered sugar (whipped to soft peaks)

 2 tbsp chocolate syrup or hot fudge

 Shaved dark chocolate or cocoa powder

Step-by-Step Instructions

1. Prepare the Crunch Layers: Combine crushed chocolate cookies with melted butter in a bowl until the texture resembles damp sand. Mix in the mini chocolate chips and set aside.

2. Make the Mousse Base: Heat ¼ cup of heavy cream until steaming (do not boil). Pour over the chopped chocolate and espresso powder. Let sit for 2 minutes, then whisk until smooth and glossy. Cool to room temperature.

3. Whip & Fold: Beat 1 ½ cups cold heavy cream with 3 tbsp powdered sugar and vanilla extract until medium peaks form. Gently fold one-third of the whipped cream into the cooled chocolate to loosen it, then fold in the remaining cream until smooth and airy.

4. Assemble the Cups:

 Layer 1: Add a layer of cookie crunch to the bottom of 4 glass cups.

 Layer 2: Pipe or spoon a generous layer of chocolate mousse.

 Layer 3: Repeat with another layer of cookie crunch/chips.

 Layer 4: Add a final layer of chocolate mousse.

5. Garnish & Serve: Top each cup with a swirl of vanilla whipped cream, a drizzle of chocolate syrup, and a sprinkle of shaved chocolate. Chill in the refrigerator for at least 1–2 hours before serving.
