Instructions
Preheat the oven to 350°F (175°C). Grease a 9-inch springform pan and line the bottom with parchment paper.
In a mixing bowl, prepare the brownie mix according to the box instructions by combining it with 2 eggs, water, and oil. Transfer the brownie batter to the prepared springform pan and bake for 15 minutes, until the brownies are set across the top.
While the brownie layer bakes, use a hand mixer or standing mixer to beat the cream cheese until light and fluffy. Add the granulated sugar and beat until well combined. Mix in the flour, vanilla extract, sour cream, and 1/4 cup of heavy cream.
Add one egg at a time, stirring by hand until fully mixed. Pour the cheesecake mixture over the baked brownie layer.
Reduce the oven temperature to 325°F (165°C). Return the springform pan to the oven and bake for 45 minutes.
After 45 minutes, turn off the oven and let the cheesecake sit inside with the door closed for 20 minutes.
Then, crack the oven door open and allow the cheesecake to cool for an additional 30 minutes.
Remove the cheesecake from the oven and let it cool to room temperature. Chill in the refrigerator for an additional 2-3 hours.
Just before serving, whip the remaining 1 cup of heavy cream with powdered sugar until stiff peaks form. Top the cheesecake with the whipped cream and a drizzle of hot fudge sauce.
Notes
For an extra touch, consider adding chopped nuts or fresh berries on top of the whipped cream.
