Viral Coraline Cookies

These Coraline cookies are inspired by the dark, whimsical world of the movie, with purple cookie dough swirled with rich black cocoa and topped with homemade purple buttercream and star sprinkles. They're soft, buttery, and have a delicious chocolate-vanilla flavor, with a different galaxy-inspired swirl in every cookie. They're such a fun dessert to make for a Coraline movie night, ACOTAR themed party, or anytime you want something a little different from classic sugar cookies!

Why You’ll Love These Coraline Cookies

I came across these viral Coraline cookies from @emijujuu and immediately knew I had to make them. I've always thought Coraline was such an interesting movie, especially with its dark, whimsical world. But there's also something so satisfying about the purple-and-black galaxy aesthetic. It even reminds me a little of the ACOTAR Night Court theme, especially with the stars, and I absolutely love that look.

For my version, I made a buttery purple cookie dough with swirls of rich black cocoa, then topped each cookie with homemade purple buttercream and star sprinkles. I love how every cookie comes out with a slightly different swirl, and the combination of vanilla and chocolate is so good.

The best part is that these look much harder to make than they actually are. You don't need to use ube, any special cookie cutters, or complicated decorating techniques to get that galaxy effect. They're such a fun treat for a Coraline movie night, Halloween party, or anyone who loves a little spooky-inspired baking!

Coraline Cookies Ingredients

For the dough:

• 1 cup unsalted butter, softened
• ¾ cup white granulated sugar
• ¼ cup light brown sugar
• 1 large egg + 1 egg yolk
• 1 tsp. vanilla extract
• Purple gel food coloring (a few drops)
• 2¼ cups all-purpose flour
• 1 tsp. baking soda
• ½ tsp. salt

For the black cocoa paste swirl:

• ¼ cup black cocoa powder
• ¼ cup powdered sugar
• 2 tbsps. melted butter
• 1 tbsp. heavy cream

For the buttercream frosting:

• ¾ cup butter, softened
• 3 cups powdered sugar
• 2 tbsps. heavy cream
• ½ tsp. purple gel food coloring
• Stars sprinkles and other sprinkles, for decorating

Ingredient Notes

• Unsalted butter. Make sure the butter is softened to room temperature for both the cookie dough and buttercream frosting. You'll also need melted butter for the black cocoa swirl. Let it cool slightly before mixing it into the cocoa powder.
• Egg and egg yolk. Using one whole egg plus an extra yolk gives the cookies a soft, chewy texture and adds richness to the dough.
• Purple gel food coloring. I recommend gel coloring instead of liquid food coloring because it creates a more vibrant purple without adding extra moisture to the dough. Start with a few drops and adjust until you get your desired shade.
• Black cocoa powder. This is what gives the cookies their dramatic black galaxy swirls. Black cocoa has a deep, dark color and a flavor similar to Oreo cookies. Regular cocoa powder won't create the same contrast, so I recommend using black cocoa for the best results.
• All-purpose flour. Spoon the flour into your measuring cup and level it off rather than scooping directly from the bag. Too much flour can make the cookies dry and prevent them from spreading properly.
• Powdered sugar and heavy cream. These create the smooth, creamy buttercream frosting. Add the heavy cream gradually until the frosting is soft enough to spread but still thick enough to hold its shape.
• Star sprinkles. These give the cookies their finishing touch and complete the purple galaxy design. I recommend using silver, white, or gold star-shaped sprinkles so they stand out against the purple frosting.

How to Make Coraline Cookies

Step 1: Make the Purple Cookie Dough

In a large mixing bowl, beat the softened butter, granulated sugar, and brown sugar with an electric mixer for 2–3 minutes, until light and fluffy. Add the egg, egg yolk, vanilla extract, and a few drops of purple gel food coloring. Mix until fully combined.

In a separate bowl, whisk together the flour, baking soda, and salt. Gradually add the dry ingredients to the wet mixture, mixing just until a soft purple cookie dough forms.

Step 2: Make the Black Cocoa Swirl

In a small bowl, combine the black cocoa powder, powdered sugar, slightly cooled melted butter, and heavy cream. Stir until a thick, smooth chocolate paste forms.

Add small dollops of the black cocoa paste throughout the purple cookie dough. Using a spatula, gently fold the dough just 2–3 times to create streaks of black and purple. Be careful not to overmix, or you'll lose the distinct galaxy swirl.

Step 3: Chill the Dough

Cover the bowl with plastic wrap and refrigerate the dough for at least 1 hour. Chilling helps firm up the butter and prevents the cookies from spreading too much while baking.

Step 4: Scoop and Bake

Preheat your oven to 350°F (175°C) and line two baking sheets with parchment paper or tin foil.

Scoop the chilled dough into 1½-tablespoon portions and place them on the prepared baking sheets, leaving about 2 inches between each cookie. Bake for 12–14 minutes, checking a little earlier if needed. The edges should be set, but the centers should still look slightly soft. Avoid overbaking so the cookies stay soft and chewy.

Step 5: Cool the Cookies

Let the cookies cool on the baking sheets for about 5 minutes before transferring them to a wire rack. Allow them to cool completely before frosting so the buttercream doesn't melt.

Step 6: Make the Purple Buttercream Frosting

In a large bowl, beat the softened butter with an electric mixer until smooth and creamy. Gradually add the powdered sugar, mixing on low speed until incorporated.

Add the purple gel food coloring a little at a time until you reach your desired shade. Mix in the heavy cream, 1 tablespoon at a time, until the frosting is smooth, fluffy, and easy to spread.

Step 7: Frost and Decorate

Spoon a generous amount of purple buttercream onto each cooled cookie. Use the back of a spoon or an offset spatula to spread and swoop the frosting across the top, creating a slightly textured finish.

Sprinkle with silver, white, or gold star sprinkles to complete the galaxy design. Serve and enjoy your homemade Coraline cookies!

My Tips for the Best Coraline Cookies

• Don't overmix the cocoa swirl. I recommend folding the black cocoa paste into the purple dough just 2–3 times. You want distinct black and purple streaks, not one blended color.
• Chill the dough before baking. Refrigerate for at least 1 hour to prevent excessive spreading and help the cookies hold their shape.
• Use gel food coloring. Gel creates a vibrant purple without adding excess liquid to the dough. I recommend making the dough slightly darker than your desired shade since the color can fade during baking.
• Don't overbake the cookies. Start checking around 10 minutes. The edges should be set while the centers are still slightly soft. They'll continue firming up as they cool.
• Cool completely before frosting. Even slightly warm cookies can melt the buttercream. I also recommend adding the star sprinkles immediately after frosting so they stick before the buttercream sets.

Coraline Cookies FAQ

What are Coraline cookies?

Coraline cookies are whimsical, spooky-inspired cookies based on the aesthetic of the movie Coraline. My version features purple vanilla cookie dough with black cocoa swirls, topped with purple buttercream frosting and star sprinkles. The purple-and-black galaxy design also has a fun ACOTAR Night Court vibe.

Can I use regular cocoa powder instead of black cocoa?

Yes! You can substitute regular unsweetened cocoa powder, but the swirls will be brown instead of deep black. For a darker color, add a small amount of black gel food coloring to the cocoa paste. I recommend black cocoa powder if you want that dramatic galaxy effect.

Can I make Coraline cookies without food coloring?

Absolutely! The food coloring is purely for appearance and doesn't affect the flavor. Without it, you'll have vanilla-colored cookies with dark chocolate swirls and regular buttercream frosting. They'll taste just as delicious, but won't have the signature purple galaxy look.

Can I make the cookie dough ahead of time?

Yes! You can prepare the cookie dough up to 2 days in advance and store it tightly covered in the refrigerator. When you're ready to bake, scoop the chilled dough into balls and bake as directed. If the dough is too firm to scoop, let it sit at room temperature for 10–15 minutes first.

How do I store Coraline cookies?

Store the frosted cookies in an airtight container in the refrigerator for up to 5 days. I recommend placing parchment paper between layers to protect the buttercream and decorations. Let the cookies sit at room temperature for about 15–20 minutes before serving so the frosting softens.

Can I freeze Coraline cookies?

Yes! I recommend freezing the cookies without frosting for the best results. Once completely cooled, place them in a freezer-safe container or bag and freeze for up to 2 months. Thaw at room temperature, then decorate with freshly made purple buttercream and star sprinkles.

Can I use store-bought frosting?

Definitely! If you want to save time, you can substitute store-bought vanilla buttercream for the homemade frosting. Mix in a little purple gel food coloring until you get your desired shade, then spread it over the cooled cookies and finish with star sprinkles.

Why did my Coraline cookies spread too much?

Excessive spreading usually happens when the butter is too warm or the dough hasn't been chilled long enough. Make sure to refrigerate the dough for at least 1 hour before baking, and avoid placing it on warm baking sheets. If the dough softens while you're working with it, return it to the refrigerator for 15–20 minutes before baking.
