Decadent Brownie Sundae Cheesecake

It was one of those rainy Sunday afternoons when the world outside felt still, and my kitchen became the coziest place on earth. I wasn’t planning to bake anything fancy, just something chocolatey enough to fix my mood and creamy enough to make it feel like self-care. That’s how this Brownie Sundae Cheesecake was born, a dessert that feels like a love child between a fudgy brownie and a rich New York-style cheesecake.

I had some leftover brownie cubes sitting on the counter, and instead of snacking on all of them (which was very tempting), I folded them into my cheesecake batter. The result? A swirl of chocolate, fudge, and creamy perfection that practically begged for whipped cream and a cherry on top.

There’s something freeing about baking just because you can—no holiday, no guests, no occasion. The oven hums, the kitchen smells like sugar and cocoa, and you remember why you fell in love with food in the first place.

If you’re craving something indulgent but not intimidating, this cheesecake is it. The best part? It looks like it belongs in a fancy café window, yet it’s ridiculously easy to pull together.

Short Description

This Brownie Sundae Cheesecake combines the best of both worlds: fudgy brownie chunks swirled into a creamy cheesecake base over a crisp chocolate cookie crust. It’s indulgent, beautiful, and surprisingly easy to make at home.

Key Ingredients

For the Fudgy Brownie Chunks

• 1 box brownie mix (plus ingredients called for on the box — usually water, eggs, and oil)

For the Chocolate Cookie Crust

• 1½ cups crushed Nilla Wafers (about 45–50 cookies)
• 6 tablespoons powdered sugar
• 6 tablespoons cocoa powder
• ½ cup unsalted butter, melted

For the Creamy Cheesecake Filling

• 32 ounces cream cheese, softened to room temperature
• 1 cup granulated sugar
• 4 large eggs
• 1 teaspoon vanilla extract
• ½ cup hot fudge sauce for swirling

Tools Needed

• 9-inch springform pan
• Electric mixer or stand mixer
• Mixing bowls
• Spatula
• Small saucepan
• Parchment paper
• Cooling rack

Cooking Instructions

Step 1: Bake the Brownies
Follow the directions on your brownie mix box and bake as instructed. Once cooled completely, cut into ¾-inch cubes. You’ll use about half for the cheesecake—feel free to snack on the rest while baking.

Step 2: Make the Crust
Preheat the oven to 350°F. In a bowl, combine crushed Nilla Wafers, powdered sugar, and cocoa powder. Pour in melted butter and mix until it resembles wet sand. Press the mixture firmly into the bottom of a 9-inch springform pan and bake for 8 minutes. Let cool while you prepare the filling.

Step 3: Prepare the Cheesecake Batter
Beat softened cream cheese and sugar until completely smooth and fluffy, no lumps allowed! Add eggs one at a time, mixing well after each addition. Stir in vanilla extract, then gently fold in half of your brownie chunks.

Step 4: Assemble the Cheesecake
Pour the cheesecake batter over the cooled crust, smoothing the top with a spatula. Drizzle the hot fudge sauce in a spiral pattern and use a knife to swirl it gently for a marbled look.

Step 5: Bake the Cheesecake
Bake at 350°F for 50–55 minutes, or until the center is set but still slightly jiggly. Turn off the oven, crack the door, and let it cool inside for 1 hour, this helps prevent cracks.

Step 6: Chill and Slice
Let the cheesecake cool completely at room temperature, then refrigerate for at least 4 hours or overnight. Run a knife around the edge before releasing the springform pan. Slice with a hot, clean knife for perfect cuts.

Step 7: Decorate and Serve
Top with extra hot fudge, whipped cream, cherries, or more brownie pieces. Go wild with the toppings, this is your sundae, after all.
