Best Hot Fudge Sundae Brownie Cheesecake – The Ultimate Dessert Treat

This over-the-top dessert comes together in about an hour of hands-on time, and it delivers the kind of creamy, chocolatey, indulgent experience that turns any evening into a celebration. You get a fudgy brownie base, a smooth and tangy cheesecake layer, and a generous drizzle of hot fudge that ties it all together. I made this for a family get-together last summer and it disappeared before the coffee was even poured.

It’s the kind of dessert that feels special without needing a pastry degree. One pan, a few simple steps, and you have a showstopper that tastes like it came from a fancy bakery.

Why You’ll Love This Recipe

• Three dessert classics in one – brownie, cheesecake, and hot fudge sundae.
• No water bath needed, so the process is much simpler than traditional cheesecake.
• The brownie layer stays dense and fudgy, giving the cheesecake a sturdy base.
• Perfect for feeding a crowd or meal-prepping dessert for the week.
• That first bite hits every craving at once – rich, creamy, cool, and warm.

Ingredients

• 1 box (18 oz) brownie mix, plus ingredients listed on box (eggs, oil, water)
• 24 oz (three 8 oz blocks) cream cheese, softened to room temperature
• 3/4 cup granulated sugar
• 3 large eggs, room temperature
• 1 teaspoon vanilla extract
• 1/2 cup sour cream, room temperature
• 1 jar (12 oz) hot fudge sauce, warmed for drizzling
• Whipped cream for serving
• Maraschino cherries for garnish (optional)

Instructions

• Preheat oven to 350°F (175°C). Line a 9×13-inch baking pan with parchment paper with some overhang for easy removal.
• Prepare the brownie batter according to package directions. Spread it evenly into the prepared pan.
• In a large bowl, beat the cream cheese and sugar together until smooth and creamy, about 2 minutes.
• Add eggs one at a time, beating well after each addition. Mix in vanilla and sour cream until just combined.
• Pour the cheesecake mixture over the brownie batter and spread it into an even layer.
• Bake for 35 to 40 minutes, until the edges are set and the center is slightly jiggly, like firm Jell-O.
• Let the cheesecake cool completely at room temperature, then refrigerate for at least 4 hours, preferably overnight.
• Once chilled, slice into squares, drizzle generously with warm hot fudge, and top with whipped cream and a cherry if desired.

Pro Tips

• Make sure your cream cheese and sour cream are truly at room temperature. Cold ingredients create a lumpy batter that won’t bake evenly.
• Do not overmix the cheesecake batter after adding the eggs. Overmixing incorporates too much air and can cause cracks as it bakes.
• For the cleanest slices, use a sharp knife dipped in hot water, then wipe it dry between each cut.
• The center should still have a slight wobble when you remove it from the oven. It will continue to set as it cools.
• If you want a deeper chocolate flavor, use a dark chocolate fudge sauce instead of milk chocolate for drizzling.

Variations

• Swap the brownie mix for a from-scratch brownie recipe if you prefer a more homemade base.
• Add a layer of chopped pecans or walnuts on top of the brownie batter before adding the cheesecake for extra crunch.
• Use a caramel or butterscotch sauce instead of hot fudge for a different flavor profile.
• Top with fresh strawberries or raspberries for a bright, fruity contrast to the rich chocolate and cream cheese.

Frequently Asked Questions

• Can I use a different pan size? A 9×9-inch pan works, but you will need to increase the baking time by about 5 to 10 minutes and the layers will be thicker.
• How long does this cheesecake keep? It stays fresh in the refrigerator for up to 5 days when stored in an airtight container.
• Can I freeze the whole cheesecake? Yes, wrap the completely cooled cheesecake tightly in plastic wrap and foil, then freeze for up to 3 months. Thaw overnight in the fridge before serving.
• Why did my cheesecake crack on top? This usually happens from overbaking or a sudden temperature change. Letting it cool slowly in the oven with the door cracked open helps prevent cracks.
• Can I make this gluten-free? Absolutely. Use a gluten-free brownie mix and check that all other ingredients are certified gluten-free.
• Do I have to use a boxed brownie mix? Not at all. You can use your favorite homemade brownie batter – just make sure it’s a thicker, fudgy style, not a cakey one.
