8 oz cream cheese, softened
½ cup powdered sugar
1 teaspoon vanilla extract

1½ cups semi-sweet chocolate chips
¾ cup heavy cream

Tools You’ll Need

9×13-inch baking dish or springform pan
Electric mixer
Mixing bowls
Spatula
Small saucepan

Step-by-Step Instructions

Prepare the Cream Filling

In a large mixing bowl, beat the softened cream cheese until completely smooth and lump-free.

Add powdered sugar and vanilla extract, beating until fully incorporated and silky.

In a separate bowl, whip the cold heavy cream until stiff peaks form.

Gently fold the whipped cream into the cream cheese mixture using a spatula, working slowly to maintain a light and airy texture.

Assemble the Oreo Layers

Arrange a single layer of Oreo cookies across the bottom of your dish, breaking cookies as needed to fill gaps.

Spread one-third of the cream filling evenly over the Oreo layer.

Repeat the layers two more times, finishing with a smooth layer of cream on top.

Make the Chocolate Ganache

Heat the heavy cream in a small saucepan until just beginning to steam. Do not boil.

Pour the hot cream over the chocolate chips in a heatproof bowl. Let sit for 2 minutes.

Stir gently until smooth, glossy, and fully melted.

Allow the ganache to cool slightly so it thickens but remains pourable.

Finish the Cake

Pour the ganache evenly over the top cream layer, gently spreading it to the edges.

Tap the dish lightly on the counter to settle the ganache.

Chill Until Set

Cover and refrigerate for at least 4 hours, preferably overnight, until the cake is fully set and sliceable.

Serving Suggestions

Serve chilled straight from the refrigerator
Top with whipped cream rosettes or crushed Oreos
Add chocolate curls or drizzle for extra flair
Slice with a warm knife for clean edges

Helpful Tips

Use full-fat cream cheese for best texture
Do not skip chilling time—the cookies need time to soften
Let ganache cool slightly before pouring to prevent melting the cream layer
Overnight chilling gives the best structure and flavor

Recipe Variations

Use mint Oreos for a mint chocolate version
Add a layer of chopped Oreos inside the cream
Swap semi-sweet chocolate for dark chocolate
Add a pinch of salt to the ganache for contrast

Storage and Make-Ahead Tips

Store covered in the refrigerator for up to 4 days.

This dessert is ideal for making a day ahead and improves in texture as it rests. Freezing is not recommended, as the cream layers may lose their smooth consistency when thawed.
