How to Make

Quick Overview

This recipe is simple but impressive: a brownie layer you bake first, a cheesecake layer poured over the cooled brownies and baked until just set, then chilled and dressed like a sundae. Preparation is straightforward, textures are rich and luscious, and the hot fudge topping provides a warm, gooey finish. Expect about 25 minutes active prep, 45–55 minutes baking, and at least 4 hours chilling.

Ingredients

• 1 box brownie mix (18 oz), plus ingredients called for on the box: 2 eggs, 1/2 cup vegetable oil, 1/4 cup water (or as directed)
• Optional: 1/2 teaspoon espresso powder, dissolved in the water for deeper chocolate flavor
• 16 ounces (2 packages) cream cheese, softened to room temperature
• 2/3 cup granulated sugar
• 2 large eggs, room temperature
• 1 teaspoon pure vanilla extract
• 1/2 cup sour cream, room temperature (or plain Greek yogurt)
• 1 tablespoon all-purpose flour (helps stabilize cheesecake)
• 1 cup hot fudge sauce, warmed (jarred or homemade)
• Optional sundae toppings: vanilla ice cream, whipped cream, chopped toasted pecans or peanuts, maraschino cherries, chocolate shavings, sea salt for sprinkling

Directions

1. Prepare the brownie mix according to the package instructions, adding eggs, oil, and water as required. If you like an extra chocolate punch, dissolve 1/2 teaspoon espresso powder in the water before mixing. Pour the batter into a greased 9×13-inch baking pan and bake according to package directions until a toothpick comes out with a few moist crumbs. Allow brownies to cool completely in the pan.
2. While the brownies cool, preheat the oven to 325°F (160°C). In a large bowl, beat the softened cream cheese until smooth and free of lumps. Add the granulated sugar and beat until well combined.
3. Add the eggs one at a time, mixing briefly after each addition until incorporated. Stir in the vanilla extract, sour cream, and flour. Mix on low speed until just smooth — avoid overmixing to prevent cracks.
4. Pour the cheesecake batter evenly over the cooled brownie base, smoothing the top with a spatula so the cheesecake layer is level. Tap the pan gently on the counter to release any large air bubbles.
5. Bake the layered dessert for 40–50 minutes, or until the center is mostly set but still has a slight jiggle. A thin knife inserted in the center should come out mostly clean. Turn off the oven, crack the door, and let the cheesecake cool inside for 30 minutes to reduce cracking.
6. Chill the cheesecake in the refrigerator for at least 4 hours, preferably overnight. When ready to serve, warm the hot fudge sauce and drizzle over individual slices. Top with a scoop of vanilla ice cream, a dollop of whipped cream, nuts, cherries, and a light sprinkle of sea salt if desired.

What to Serve With

• Classic pairings: A scoop of high-quality vanilla ice cream and a drizzle of hot fudge make the dessert feel like a sundae.
• Coffee and dessert wines: Strong espresso or a sweet dessert wine such as tawny port pairs beautifully with the chocolate and cream.
• Lighter sides: Fresh berries or a simple mint salad provide a bright contrast to the richness.
• For a brunch twist: Serve smaller slices with fresh fruit and a dollop of Greek yogurt.

Top Tips for Perfecting

• Use room-temperature cream cheese and eggs for a smooth, lump-free cheesecake batter.
• Cool brownies completely before adding cheesecake; a warm base can cause the layers to mix and bake unevenly.
• If you’re worried about cracks, place a pan of hot water on the lower oven rack for a gentle steam bath while baking.
• Substitute sour cream with full-fat Greek yogurt for a tangy lift; add an extra teaspoon of flour if you prefer a firmer texture.
• For extra fudginess, fold a few chopped chocolate chunks into the brownie batter before baking.

Storing and Reheating Tips

• Refrigeration: Store covered in the refrigerator for up to 4 days. Keep slices on a flat tray with plastic wrap pressed lightly over the surface to prevent drying.
• Freezing: Wrap tightly in plastic wrap and then foil; freeze for up to 2 months. Thaw in the refrigerator overnight before serving.
• Reheating: Warm slices briefly in the microwave (10–15 seconds) to loosen the hot fudge, or gently warm only the hot fudge and pour over chilled slices to maintain cheesecake texture.

FAQs

How long should I chill the cheesecake before serving?
Chill at least 4 hours, though overnight is best for clean slices and fully set texture.

Can I make this entirely from scratch without a boxed mix?
Yes. Use your favorite homemade brownie recipe and bake it in the same pan; proceed with the cheesecake layer once cooled.

Why did my cheesecake crack on top?
Cracks often result from overmixing, sudden temperature changes, or overbaking. Avoid high-speed mixing and cool the cheesecake gradually.

Can I use a springform pan instead of a 9×13 pan?
Yes — reduce brownie batter to fit a 9- or 10-inch springform and adjust baking time accordingly. A springform gives a taller, fancier presentation.

Is it okay to prepare components a day ahead?
Absolutely. Bake the brownies and make the cheesecake layer the day before; assemble and chill overnight for best results.
