Ingredients

Cooking spray
2 boxes brownie mix, plus ingredients called for on box

2 (8-oz.) blocks cream cheese, softened
4 cups powdered sugar

2 teaspoons pure vanilla extract
1/4 teaspoon kosher salt

2 cups chocolate chips
1 cup heavy cream
1/4 cup chocolate shavings

Instructions

Step 1: Preheat the oven to 350°F. Line a 9”-x-13” baking pan with parchment paper and grease with cooking spray. Prepare brownie mixes according to package directions and pour both batters into the prepared pan. Bake about 40 minutes or until a toothpick inserted into the center comes out clean. Let the brownies cool completely.
Step 2: In a large bowl, beat the softened cream cheese with a hand mixer until smooth. Gradually add powdered sugar and beat until no lumps remain. Add vanilla extract and kosher salt, then mix until combined.
Step 3: To make the ganache, place chocolate chips in a heatproof bowl. Heat the heavy cream over medium heat in a small saucepan until it comes to a boil. Pour the hot cream over the chocolate chips and let it sit for 5 minutes, then whisk gently until smooth. Allow the ganache to cool slightly.

Step 4: Remove the cooled brownie from the pan and cut it in half widthwise. Then cut each half in half horizontally, creating four thin layers. Place one brownie layer on a serving platter, spread a thin layer of ganache on top, then spread about one-third of the cream cheese filling over it. Repeat layering with brownies, ganache, and cream cheese, finishing with a final brownie layer topped with ganache. Reserve some ganache for serving. Refrigerate for at least 1 hour to chill and set.
Step 5: Before serving, garnish the top with chocolate shavings and drizzle with the reserved ganache for an extra touch of elegance and flavor.

Tips & Variations

For a nutty twist, add chopped walnuts or pecans to the brownie batter before baking.

Use homemade brownies if preferred for a more personalized flavor.
Substitute the cream cheese layer with whipped mascarpone mixed with powdered sugar for a lighter texture.
Chill the ganache fully to achieve a thicker spread if desired.

Storage

Store the brownie lasagna covered in the refrigerator for up to 3 days. To serve, let it sit at room temperature for 10–15 minutes to soften slightly, or warm gently in the microwave for 10 seconds if preferred. Avoid freezing to preserve texture and flavor.

FAQs

Can I make brownie lasagna ahead of time?

Yes, brownie lasagna tastes even better when made ahead as the flavors meld during chilling. Prepare it up to one day in advance and keep refrigerated until ready to serve.

Can I use a different type of chocolate for the ganache?

Absolutely. Semi-sweet, bittersweet, or milk chocolate chips all work well for ganache. Choose the type that suits your sweetness preference.
