Instructions
Step 1: Prepare the Brownie Base
Preheat oven to 350°F (175°C). Line a 9-inch springform pan with parchment paper and lightly grease the sides. Prepare the brownie mix according to package directions, using oil, water, and egg. Pour the batter into the prepared pan and bake for 20–25 minutes, until just set in the center. Let it cool slightly while you prepare the cheesecake layer.
Step 2: Make the Cheesecake Filling
In a large bowl, beat the softened cream cheese and sugar until smooth and creamy. Add eggs one at a time, mixing well after each addition. Blend in vanilla extract and sour cream until fully combined.
Step 3: Assemble and Bake
Pour the cheesecake mixture over the slightly cooled brownie layer. Smooth the top with a spatula. Bake for 35–40 minutes, or until the edges are set but the center is slightly jiggly. Turn off the oven, crack the door open, and let the cheesecake rest inside for 1 hour. This helps prevent cracks.
Step 4: Chill and Set
Remove from oven and cool completely at room temperature. Cover and refrigerate for at least 4 hours, or overnight, until firm.
Step 5: Prepare the Ganache
In a small saucepan, heat heavy cream until just simmering. Pour it over the chocolate chips in a bowl. Let sit for 2 minutes, then stir until smooth and glossy. Let the ganache cool slightly before pouring over the chilled cheesecake. Spread evenly and return to the fridge for 20 minutes to set.
Step 6: Add Sundae Toppings and Serve
Slice the cheesecake and top each piece with a scoop of vanilla ice cream, a drizzle of hot fudge, whipped cream, nuts, and a cherry on top. Serve immediately for that perfect brownie sundae experience.
Tips for Success
- Room temperature cream cheese: Essential for a smooth, lump-free cheesecake layer.
- Don’t overbake: Slight jiggle in the center means perfect texture.
- Cool gradually: Prevents cracks and ensures even texture.
- For neat slices: Use a warm knife wiped clean between cuts.
- Make-ahead perfection: Tastes even better after resting overnight in the fridge.
Variations and Customizations
- Caramel swirl: Add caramel sauce between brownie and cheesecake layers.
- Peanut butter lover’s twist: Mix ¼ cup peanut butter into the cheesecake filling.
- Mocha magic: Add 1 tablespoon instant coffee to the brownie batter for depth.
- White chocolate version: Use white chocolate ganache for a stunning contrast.
- Mini cheesecakes: Bake in a muffin tin for personal-sized treats.
Serving Suggestions and Pairing Ideas
- Party-style: Serve with an ice cream bar where everyone adds their own toppings.
- Elegant dessert: Top with a thin drizzle of ganache and gold sprinkles for a fancy look.
- Temperature options: Enjoy chilled for creamy texture or slightly warmed for gooey decadence.
- Drink pairings: Pairs beautifully with espresso, hot chocolate, or a glass of cold milk.
Storage and Make-Ahead Instructions
Room Temperature: Best kept chilled once assembled; can sit at room temp for up to 1 hour before serving.
Refrigerator: Store covered for up to 5 days. The flavors develop beautifully after the first day.
Freezer: Freeze slices (without ice cream topping) tightly wrapped for up to 1 month. Thaw overnight in the fridge before serving.
Make-Ahead Tip: Prepare the cheesecake base and ganache a day ahead. Add sundae toppings right before serving for the freshest taste.
