How to Make Hot Fudge Sundae Brownie Cheesecake
Step 1: Prepare the Pan and Oven
Preheat the oven to 325°F (163°C). Lightly grease a 9-inch springform pan and line the bottom with parchment paper. Wrap the outside of the pan with foil if you plan to use a water bath, taking care to keep water from entering the pan.
Step 2: Make the Brownie Batter
In a medium bowl, whisk together the melted vegan butter and sugar. Add the cocoa powder, vanilla, plant-based milk, flour, and salt. Stir just until combined. Fold in the dairy-free chocolate chips if using.
Spread the batter evenly over the bottom of the prepared pan. Bake for about 10–12 minutes, just until the surface begins to set. Remove from the oven and let it cool slightly while you prepare the filling.
Step 3: Prepare the Cheesecake Filling
In a large bowl, beat the softened vegan cream cheese until smooth. Add the sugar and mix until incorporated. Beat in the vegan yogurt, cornstarch, vanilla extract, and lemon juice until the mixture is creamy and free of large lumps.
Avoid overbeating, which can incorporate excess air and affect the final texture. Scrape down the sides of the bowl as needed.
Step 4: Assemble the Layers
Pour the cheesecake mixture over the partially baked brownie base. Smooth the top with a spatula and gently tap the pan on the counter to release large air bubbles.
Step 5: Bake the Cheesecake
Place the springform pan on a larger baking tray. If using a water bath, place the foil-wrapped pan in a roasting pan and carefully add hot water around it, keeping the water below the foil edge.
Bake at 325°F (163°C) for approximately 45–55 minutes. The edges should look set while the center may still have a slight wobble. Baking time varies by oven and the brand of plant-based cream cheese.
Turn off the oven and leave the cheesecake inside with the door slightly open for about 15–20 minutes. Remove it carefully and let it cool on a rack.
Step 6: Chill Until Firm
Once the cheesecake has cooled, cover it and refrigerate for at least 6 hours, preferably overnight. This chilling time is essential for the filling to firm up and for clean slices.
Step 7: Make the Hot Fudge Sauce
Place the plant-based cream, dairy-free chocolate chips, and maple syrup in a small saucepan over low heat. Stir gently until the chocolate melts and the sauce becomes smooth.
Remove from the heat and stir in the vegan butter, if using, and vanilla extract. Let the sauce cool for a few minutes until warm and pourable. If it becomes too thick, stir in a little extra plant-based cream.
Step 8: Add the Sundae Toppings
Release the chilled cheesecake from the springform pan and transfer it to a serving plate. Drizzle some warm fudge sauce over the top, allowing a little to run down the sides.
For a classic sundae finish, add scoops of dairy-free vanilla ice cream and small swirls of vegan whipped topping. Sprinkle with chocolate shavings, chopped nuts, and cherries if desired.
Step 9: Slice and Serve
For neat slices, use a sharp knife warmed in hot water and wiped dry between cuts. Serve immediately after adding the ice cream, while the fudge sauce is still warm.
If serving a crowd, keep the cheesecake chilled and let guests add their own ice cream and toppings to each slice.
Tips for the Best Brownie Cheesecake
- Use baking-style vegan cream cheese: Different brands vary in moisture and firmness, which can affect how the filling sets.
- Let the brownie base partially bake: This helps it support the cheesecake layer.
- Bring the filling ingredients to room temperature: Softer cream cheese blends more smoothly.
- Avoid overbaking: The center should retain a slight wobble when the cheesecake comes out of the oven.
- Allow enough chilling time: Cutting the cheesecake too early can cause the layers to crumble or slide.
- Add ice cream just before serving: It melts quickly on a chilled cheesecake.
- Check labels: Chocolate, whipped topping, ice cream, and decorations must all be dairy-free and egg-free for a vegan dessert.
Easy Variations
Chocolate Cheesecake Filling
For an even more chocolate-forward dessert, mix 2 tablespoons of sifted cocoa powder into the cheesecake filling. You may need a small splash of plant-based milk if the mixture becomes too thick.
Peanut Butter Fudge Brownie Cheesecake
Swirl 2–3 tablespoons of smooth peanut butter into the cheesecake filling before baking. Add chopped roasted peanuts to the finished dessert for extra crunch.
Cherry Chocolate Sundae Cheesecake
Top each slice with cherries and a spoonful of cherry sauce. The fruity flavor balances the richness of the brownie, cheesecake, and fudge.
Nut-Free Option
Choose oat or soy milk-based products where suitable, and skip the chopped nuts. Check labels for cross-contact warnings if the dessert is being served to someone with a serious nut allergy.
How to Store Leftovers
Refrigerator
Store the cheesecake without ice cream or whipped topping in an airtight container in the refrigerator for up to 4 days. Keep it refrigerated at 40°F (4°C) or below. Add the sundae toppings just before serving.
Freezer
For longer storage, freeze the cheesecake without the ice cream, whipped topping, or hot fudge. Wrap individual slices securely and place them in a freezer-safe container for up to 2 months for best quality. Thaw overnight in the refrigerator.
Can You Make It Ahead?
Yes. Bake the brownie cheesecake the day before and refrigerate it overnight. Prepare the fudge sauce separately and refrigerate it in a covered container. Warm the sauce gently before serving, then add the ice cream and other toppings at the last moment.
Frequently Asked Questions
Is this Hot Fudge Sundae Brownie Cheesecake vegan?
This version is designed to be vegan when every ingredient is plant-based. Use vegan butter, dairy-free chocolate, vegan cream cheese, plant-based yogurt, dairy-free ice cream, and vegan whipped topping. Always check the product labels.
Why does my vegan cheesecake seem soft?
Plant-based cream cheese brands vary, and the filling may need more time to chill. Refrigerate for at least 6 hours, preferably overnight, before slicing. If it remains too soft, the filling may need a recipe adjustment for the specific brand used.
Can I make this dessert without a springform pan?
A deep cake pan lined with parchment can work, but removing the cheesecake will be more difficult. A springform pan is recommended for easier release and cleaner presentation.
Can I use store-bought brownies?
You can use a suitable vegan brownie as the base, but its thickness and moisture will affect the result. Make sure the brownie fits the pan and is firm enough to support the cheesecake filling.
When should I add the hot fudge and ice cream?
Add the fudge shortly before serving, then top each slice with ice cream and whipped topping. This keeps the cheesecake neat and prevents the ice cream from melting into the dessert before it reaches the table.

This Hot Fudge Sundae Brownie Cheesecake brings together everything that makes a chocolate dessert memorable: a rich brownie base, a creamy cheesecake center, and warm fudge sauce with classic sundae toppings.
