How to Make Indulgent Heavenly Hot Fudge Sundae Brownie

Preheat and Prepare: Preheat your oven to 350°F (175°C). Line a 9-inch springform pan with parchment paper and grease the sides to prevent sticking.
Mix Brownie Batter: Follow the package instructions for the brownie mix, adding espresso powder if you like. Spread the batter evenly in the prepared pan and bake for 20-25 minutes, until the edges are set but the center remains slightly underdone. Allow to cool slightly.
Prepare Cheesecake Filling: In a large bowl, beat softened cream cheese until smooth. Gradually add granulated sugar, then mix in eggs one at a time, followed by sour cream, vanilla, and flour. Blend until fully combined and creamy.
Pour Filling: Gently pour the cheesecake filling over the cooled brownie base, ensuring an even spread. Reduce the oven temperature to 325°F (160°C).
Bake in a Water Bath: Set the springform pan into a larger roasting pan and fill it with hot water halfway up the sides of the springform. Bake for 55-65 minutes, or until the edges are firm and the center jiggles slightly but isn’t liquid.
Cool Gradually: Once baked, turn off the oven and crack the door open. Let the cheesecake cool in the oven for 1 hour to maintain moisture, then cool to room temperature before refrigerating for 4-6 hours or preferably overnight.
Heat Hot Fudge: Just before serving, warm the hot fudge until it’s pourable and spread it generously over the chilled cheesecake. Chill for an additional 20 minutes to allow it to set.
Serve and Garnish: Finally, decorate each slice with a dollop of whipped cream, a sprinkle of colorful toppings, and a maraschino cherry on top for that classic sundae feel!

Optional: Consider adding a drizzle of caramel sauce for an extra layer of flavor.

Indulgent Heavenly Hot Fudge Sundae Brownie Recipe FAQs

How do I choose the right brownie mix?
Absolutely! Look for a brownie mix that lists cocoa powder or chocolate as the first ingredient for a richer flavor. I often choose brands that promise fudginess rather than cake-like textures, as the former pairs beautifully with the cheesecake layer.

How should I store leftovers?
Store any leftover Indulgent Heavenly Hot Fudge Sundae Brownie in an airtight container in the refrigerator for up to 3-4 days. This keeps the flavors fresh and maintains the creamy cheesecake layer. Be sure to place parchment paper between layers if stacking for easy serving later!

Can I freeze the brownies?
Yes! To freeze your Heavenly Hot Fudge Sundae Brownie, wrap them tightly in plastic wrap and then in aluminum foil. This ensures no freezer burn. They can be frozen for up to 2 months. When you’re ready to enjoy them, simply thaw in the fridge overnight or at room temperature for a couple of hours.

What if my cheesecake cracks during baking?
Very! Cheesecake cracks can happen, but don’t worry; they are quite common. To prevent this, always bake your cheesecake in a water bath and avoid opening the oven door too early. If a crack does appear, you can hide it with hot fudge or whipped cream topping—no one will be the wiser!

Is this dessert pet-friendly?
It’s best to keep this delicious dessert away from pets, especially due to the chocolate and sugar content, which can be harmful to them. Always ensure that any leftovers are stored securely out of reach.

What if I have dietary restrictions?
