The galaxy design looks complicated but it’s actually just swirling colors with a toothpick. Even beginners can nail this technique on their first try, and each cheesecake comes out uniquely beautiful.
It’s also make-ahead friendly. Prep it the night before your event and let it chill while you handle everything else.
Ingredients You’ll Need
The ingredient list is straightforward with items you can find at any grocery store. Use full-fat cream cheese for the best texture—low-fat versions don’t set as well.
For the crust: chocolate sandwich cookies (like Oreos) and melted butter. For the filling: cream cheese, creamy peanut butter, powdered sugar, vanilla, and heavy cream. For the galaxy effect: gel food coloring in purple, blue, and black.
Gel colors work better than liquid because they won’t thin out your filling. You can find them in the baking aisle or at craft stores.
How to Make the Crust
Crush the chocolate cookies into fine crumbs using a food processor or by placing them in a sealed bag and crushing with a rolling pin. Mix the crumbs with melted butter until they resemble wet sand.
Press the mixture firmly into the bottom of a 9-inch springform pan. Use the bottom of a measuring cup to pack it down evenly and create a solid base.
Chill the crust in the freezer for 15 minutes while you prepare the filling. This helps it firm up and makes assembly easier.

minutesIngredients
- For the Crust
24 chocolate sandwich cookies (like Oreos)
5 tablespoons unsalted butter, melted
- For the Filling
16 oz (2 packages) cream cheese, softened
1 cup creamy peanut butter
1 cup powdered sugar
2 teaspoons vanilla extract
1½ cups heavy whipping cream, cold
- For the Galaxy Effect
Purple gel food coloring
Blue gel food coloring
Black gel food coloring (optional)
Directions
- Make the crust: Pulse cookies in a food processor until fine crumbs form. Mix with melted butter until combined. Press firmly into the bottom of a 9-inch springform pan. Freeze for 15 minutes.
- Prepare the filling: Beat cream cheese with an electric mixer until smooth and fluffy, about 2 minutes. Add peanut butter, powdered sugar, and vanilla. Beat until well combined.
- Whip the cream: In a separate bowl, whip heavy cream to stiff peaks. Gently fold whipped cream into the peanut butter mixture in three additions until fully incorporated.
- Create galaxy colors: Remove about 2 cups of filling and divide into three small bowls. Tint one purple, one blue, and one with a tiny bit of black (or dark purple).
- Assemble: Pour plain filling over the crust and smooth the top. Drop spoonfuls of colored filling randomly over the surface.
- Create swirls: Use a toothpick or skewer to gently swirl colors together with 5-6 pulls through the filling. Don’t over-swirl.
- Chill: Cover and refrigerate for at least 6 hours or overnight until firm and set.
- Serve: Remove springform ring. Slice with a hot, clean knife, wiping between cuts. Serve chilled.
Notes
- Make ahead: This cheesecake tastes even better after 24 hours in the fridge as flavors meld.
Peanut butter swap: Use almond butter or sunflower seed butter for a nut-free version.
Color tips: Gel colors work best. Start with small amounts—you can always add more. - Storage: Keep covered in refrigerator up to 5 days. Freeze up to 2 months wrapped tightly.
Serving tip: Let cheesecake sit at room temperature for 10 minutes before slicing for cleaner cuts.

Making the Peanut Butter Filling
Beat softened cream cheese with an electric mixer until completely smooth with no lumps. Add peanut butter, powdered sugar, and vanilla, then beat until fluffy and well combined.
In a separate bowl, whip the heavy cream to stiff peaks. Gently fold the whipped cream into the peanut butter mixture in three additions to keep it light and airy.
The filling should be thick, smooth, and hold its shape. Don’t overmix once you add the whipped cream or you’ll deflate it.
Creating the Galaxy Effect
Divide about 2 cups of filling into three small bowls. Add a few drops of purple gel coloring to one, blue to another, and a tiny amount of black to the third.
Pour the plain filling into the crust and smooth the top. Drop spoonfuls of the colored filling randomly over the surface, then use a toothpick or skewer to swirl them together gently.
Don’t over-swirl—just a few pulls through the colors creates the best galaxy effect. You want distinct color pockets, not a muddy mess.
Chilling and Serving
Cover the cheesecake loosely with plastic wrap and refrigerate for at least 6 hours, or preferably overnight. The filling needs this time to set properly into a sliceable texture.
When ready to serve, run a knife under hot water, dry it, and slice. Clean the knife between cuts for perfect slices. The colors look even more vibrant once fully chilled.
Serve cold and store leftovers covered in the refrigerator for up to 5 days. This cheesecake also freezes beautifully for up to 2 months.
Frequently Asked Questions
Can I make this cheesecake without peanut butter?
Yes! Replace the peanut butter with an equal amount of additional cream cheese or try cookie butter, Nutella, or Biscoff spread for different flavors. The texture will remain creamy and delicious.
How do I know when the cheesecake is set?
The cheesecake is ready when the filling is firm to the touch and doesn’t jiggle when you gently shake the pan. If it’s still wobbly after 6 hours, give it a few more hours to chill.
Can I use natural peanut butter?
Regular processed peanut butter works best because it’s more stable. Natural peanut butter can separate and make the filling oily. If using natural, drain off excess oil and stir very well before measuring.
