Cosmic Brownie Cheesecake Delight

Cosmic brownie cheesecake is the ultimate treat for chocolate lovers when you want nostalgic comfort with a little grown up flair. With a fudgy brownie base topped by luscious chocolate cheesecake and finished with silky ganache plus candy coated chips this showstopper gets cheers every time I bring it to parties. It combines two of my childhood favorites into one jaw dropping dessert.

I made this for my best friend’s birthday as a surprise and it instantly disappeared before dinner even started. Just seeing those candy colored chips on top sparked so many memories of lunchbox brownies and lazy Saturday afternoons growing up.

Ingredients

• Bittersweet chocolate: Provides a bold cocoa flavor for the brownie crust Choose bars with at least seventy percent cacao for deep flavor
• Unsalted butter: Makes the brownie chewy not greasy Pick European style for extra richness
• Granulated sugar: Sweetens both brownie and cheesecake Always choose fresh sugar—clumped sugar means it is old
• Eggs: Add structure and moisture Room temperature eggs mix in smoothly and keep layers creamy
• Vanilla extract: Deepens flavor Pure vanilla gives the richest aroma avoid artificial if you can
• All purpose flour: Is the perfect base for chewy brownies Look for unbleached for best texture
• Cocoa powder: Punches up chocolate intensity Use Dutch process for a darker color and smoother taste
• Salt: Balances and heightens the sweetness Choose fine sea salt for best distribution
• Semi sweet chocolate chips: Melt smoothly for the cheesecake and ganache Use a well known brand to avoid waxy texture
• Full fat cream cheese: Ensures that classic dense cheesecake interior Always soften at room temp for the smoothest mix
• Sour cream: Gives tangy creaminess that cuts the sweetness Select full fat and never use low fat for best results
• Heavy cream: Creates silky smooth ganache Opt for fresh not ultrapasteurized
• Candy coated chocolate pieces: Add the signature cosmic flair and a fun crunch Look for ones with crisp shells and bright colors

Step-by-Step Instructions

Brownie Crust:

Prep the Pan Line a nine inch springform pan with parchment and wrap the bottom in foil to prevent leaks. This protects your cheesecake from water and makes removal easy.

Melt Chocolate and Butter:

Place bittersweet chocolate and butter in a microwave safe bowl Heat in thirty second bursts stirring every time until fully melted and glossy Let cool briefly so it does not cook the eggs

Whip the Eggs and Sugar:

With a hand mixer whip sugar eggs and vanilla on medium high until pale and frothy This aerates the batter for a shiny brownie crust

Combine Wet Ingredients:

Slowly pour the slightly cooled chocolate butter mixture into the whipped eggs while mixing to fully blend and cool gently

Add Dry Ingredients:

Sift flour cocoa powder and salt over the wet mix Fold gently until no dry streaks remain This keeps the brownie from getting tough

Bake the Brownie:

Spread batter evenly in the pan and bake at three hundred fifty degrees for twenty five to thirty minutes It is ready when a toothpick inserted comes out clean Cool completely in the pan

Cheesecake Filling:

Prep the Oven and Water Bath Lower oven temperature to three hundred twenty five degrees Fill a large casserole with warm water and set it on the bottom rack This creates steam to prevent cracks

Melt Chocolate for the Filling:

Place chocolate chips in a microwave safe bowl Heat in thirty second bursts stirring until fully smooth Let cool slightly before adding to cheese

Beat Cream Cheese and Sugar:

Beat softened cream cheese and sugar in a large bowl until smooth and creamy Scrape the bowl to break up any lumps

Build Flavors:

Pour in the melted chocolate then beat in vanilla cocoa powder and salt Add the sour cream and beat just until blended

Add Eggs One at a Time:

Add eggs one by one mixing on low after each Add slowly so the cheesecake stays airy Scrape bowl after each addition

Pour and Bake:

Pour cheesecake batter over cooled brownie layer smooth the top and place above water bath on middle oven rack Bake for sixty to seventy minutes until edge is set and center jiggles when tapped

Cool Slowly:

Once baked crack oven door and let cheesecake cool inside for an hour Then let cool at room temp another hour before refrigerating overnight This prevents cracks and ensures creamy texture

Chocolate Ganache:

Prepare Ganache Place chocolate chips in a large bowl Heat heavy cream until steaming and pour over chips Let sit for a minute before whisking together until glossy and smooth

Chill Ganache:

Place plastic wrap over ganache and refrigerate for an hour until slightly thickened

Finish and Decorate:

Once cheesecake and ganache are cool remove pan sides and parchment Spread ganache evenly over the cheesecake and sprinkle with candy coated chocolate chips Slice and serve chilled

I love using extra bitter chocolate for the base because any leftover brownies become perfect ice cream sundaes Later my little cousin told me she thought cosmic brownies should always taste like cheesecake from now on She is officially obsessed

Storage Tips

This cheesecake keeps well covered in the fridge for up to five days The ganache thickens as it chills so if you like a shiny finish add just before serving For longer storage you can freeze individual slices on a tray then wrap tightly and freeze up to two months Thaw slices in the fridge overnight for best texture

Ingredient Substitutions

If you do not have bittersweet chocolate you can use all semi sweet chips in both the crust and cheesecake Just reduce sugar slightly Dutch process cocoa gives a deeper flavor but regular cocoa works in a pinch Greek yogurt can stand in for sour cream in a bind Choose bold chocolate chips for ganache to add your own twist

Serving Suggestions

Serve straight from the fridge or let slices stand at room temp for 10 minutes for extra creamy bites The bright candy chips make this perfect for birthday parties or holiday dessert tables You can also top slices with scoops of vanilla or mint ice cream for next level decadence
