Growing up, were you always excited to see which Little Debbie treats were in the grocery bags when they arrived home?

Cosmic Brownies and Nutter Bars were always at the top of my list. 

Today, I wanted to use one of my favorite childhood treats in a yummy, more “grown-up” dessert. 

(Fair warning: expect numerous cosmic/starry puns ahead, sorry not sorry)

My brownie chocolate cheesecake, inspired by the beloved Little Debbie Cosmic Brownies, is a heavenly confection that combines the best of both worlds—fudgy cosmic brownies and velvety chocolate cheesecake. 

In just a few steps, you can create a dessert masterpiece that’ll be the star of any gathering. Let’s dive into the magic of this indulgent treat!

Oreo crust

The Perfect Brownie Chocolate Cheesecake

Creating the Perfect Crust and Filling:

  1. Oreo Crust: Crushed Chocolate Oreos mixed with melted butter form the base—a delightfully rich and crumbly crust.
  2. Cheesecake Dream: A delicious chocolate cream cheese mixture, elevated with vanilla extract and melted bittersweet chocolate, creates the velvety cheesecake layer that promises to melt in your mouth.
  3. Cosmic Brownie Throwbacks: Chopped cosmic brownies are scattered between layers, infusing each bite with nostalgic fudgy brownies goodness.

How to Bake Your Brownie Chocolate Cheesecake

Baking homemade cheesecakes can seem daunting—but they are really easy to make!

Once your cheesecake filling is mixed, you will pour half of your batter into your springform pan.

Top the batter with chopped Cosmic Brownies, as shown above.

Then, add the remaining batter on top of the chopped brownies.

We bake our cheesecakes in a water bath, wrapped securely in aluminum foil, to ensure a moist and evenly cooked cheesecake. This method prevents cracks and elevates the texture to a silky, fudgy delight.

The Icing on the Brownie Chocolate Cheesecake—Literally

The final touch involves a generous layer of chocolate icing that cascades over the cheesecake, creating a glossy finish, similar to a chocolate ganache. Adding sprinkles and cubed cosmic brownie pieces is the pièce de resistance, turning this dessert into something you’ll feel proud serving at your next birthday party or family dinner!

Pro Tips for the Best Results:

  • Use a High Quality Springform Pan: Invest in a high-quality springform pan for easy removal and presentation.
  • Bake Smart: Use a water bath and the right oven temperature for a flawless, crack-free cheesecake. Here is my go-to method for how to make a cheesecake water bath.
  • Chilled Goodness: Refrigerate the cheesecake overnight to let the flavors meld and intensify.
  • Have Fun Decorating: We poured chocolate icing to create a chocolate ganache glaze. Then we used the remaining chocolate icing and piped it on using a 1M tip. Chop extra Cosmic Brownies and place them on top of the cheesecake! If you don’t have a piping bag, you could always use a gallon Ziploc bag.

Cheesecake Serving Suggestions:

  • Slice and serve chilled for the ideal texture and flavor.
  • Pair with a dollop of whipped cream or a scoop of vanilla ice cream for an extra treat.
  • Sprinkle extra cosmic brownie bits on individual slices for a playful touch.

Storing Your Cheesecake: 

After indulging in this “cosmic” creation, store any leftovers in an airtight container in the refrigerator. The flavors continue to meld, making each subsequent slice even more delightful.
