Description
This rich, creamy cheesecake sits on a fudgy cosmic brownie crust and gets a playful finish with rainbow sprinkles—perfect for celebrations.
Ingredients
For the Brownie Layer:
1 box cosmic brownie mix (or 1 batch of baked and cooled cosmic brownies)
For the Cheesecake Filling:
16 oz (450 g) cream cheese, softened
½ cup granulated sugar
2 large eggs, room temperature
1 tsp vanilla extract
½ cup sour cream
Optional Topping:
¼ cup rainbow sprinkles
Instructions
Preheat oven to 325°F (165°C) and line a 9-inch springform pan with parchment.
Crumble the brownies into the pan and press into a firm crust layer.
Beat cream cheese and sugar until smooth, about 2 minutes.
Add eggs one at a time, then mix in vanilla and sour cream until just blended.
Pour cheesecake filling over brownie crust and smooth the top.
Bake for 45–55 minutes, until edges are set and center jiggles slightly.
Turn off the oven, crack the door, and cool cheesecake inside for 1 hour.
Run a knife around the edge and cool completely on a wire rack.
Refrigerate at least 4 hours or overnight.
Before serving, top with sprinkles and slice using a warm, wet knife.
Notes
Press brownie crust evenly for a stable base.
Chill thoroughly for clean slices and best flavor.
