Galaxy Cookies: Star shaped cutout cookies with a galaxy glaze
It’s taken me every ounce of self restraint with these cookies to not say something super cheesy like “they’re outta this world”. Because, while they totally, absolutely are, you don’t need cute quips to inform you of that, do you? These cookies make their own statements, and none of them are mundane.
I’ve been seeing some pretty incredible galaxy desserts all over the internet recently, and wanted to offer up my own spin on these out of this world desserts. They’re not difficult to make, but there are quite a few steps involved, so let’s get started.
The patterns and whorls of these galaxy cookies look complex and intricate, but the process for making them is actually really, really simple.
Use a toothpick to dab bright pink, blue, and purple food coloring into a simple vanilla glaze, and then drag the toothpick around the surface until the swirls look spacey enough. You literally cannot mess this step up — every slip of the toothpick just makes things more interesting (just… don’t over stir or all the colors will run together).
Then dip the face of each cutout cookie into the surface of the glaze until it is completely coated, remove, and allow it to set on a cookie sheet until hardened. I’ve said this before, but for a person with as little patience as me this is completely true — the hardest part is waiting.
I let my cookies set overnight so I know the glaze is fully set, but you can wait as little as 30 minutes if you don’t mind slightly soft glaze.
There are some important notes about these cookies that I want to make; be sure to go over these before you begin. They are simple tips that will make this process even easier:
- Choose an extract that you really like to flavor the glaze. I found simply using vanilla to be too plain and it left too much space for that bitter food coloring flavor. I recommend using half a teaspoon of vanilla and then ¼-1/2 teaspoon of an extract of your choice. My favorite is almond, but I think mint or coconut would also be delicious. Taste test before swirling and dipping!
- The less food coloring the better. The more white glaze you have swirled in, also the better. Food coloring has a pretty pungent flavor. Use gel colorings for the most vibrant color, and dip a clean toothpick into the well of each and then into glaze. Repeatedly if needed. This allows you more control than just squirting the coloring directly into the bowl.
- Food coloring stains everything! Any porous surface it comes into contact with — wood, plastic, skin. I always lay out a sheet of wax paper to protect the surface I’m working on from becoming permanently stained.
I used dark chocolate cocoa powder to color these cookies nice and dark (you know, like the night sky…) without any additional food coloring. They don’t have a very strong chocolate taste to them, though, and you can easily substitute regular cocoa powder or use this (non-chocolate) cutout cookie recipe to use as your base instead.
Enjoy!
Galaxy Cookies
Ingredients
Cutout Cookies
- 1 cup (226 g) unsalted butter softened
- ⅔ cup (135 g) granulated sugar
- 1 tsp vanilla
- 1 large egg yolk lightly beaten
- 2 cups (270 g) all-purpose flour
- ⅓ cup (35 g) dark cocoa powder
- ½ tsp salt
Galaxy Glaze
- 3 cups (375 g) powdered sugar sifted
- 3-4 Tbsp milk
- 3 Tbsp light corn syrup
- ½ tsp vanilla
- ¼ tsp almond extract or your preferred flavoring
- gel food coloring pink, blue, and purple
Instructions
Cookies
- In stand mixer fitted with paddle attachment, cream butter.1 cup (226 g) unsalted butter
- Add granulated sugar and beat until light and fluffy.⅔ cup (135 g) granulated sugar
- Add vanilla and stir well.1 tsp vanilla
- Stir in lightly beaten egg yolk. Scrape down sides of bowl as needed to evenly incorporate all ingredients.1 large egg yolk
- In separate bowl, combine flour, cocoa powder and salt.2 cups (270 g) all-purpose flour, ⅓ cup (35 g) dark cocoa powder, ½ tsp salt
- With mixer on medium-low speed, gradually add flour until well-incorporated (you will definitely need to scrape down the sides and the bottom of the bowl several times for this, as the mixture is fairly dry and crumbs tend to settle at the bottom of the bowl).
- Transfer dough to clean surface and use your hands to form it into a cohesive ball.
- Flatten into a disk (about 1" thick), cover with clear wrap, and chill for 30 minutes.
- Preheat oven to 350F and line cookie sheet with parchment paper.
- Once dough has chilled, transfer it to a clean, lightly floured surface and use a lightly floured rolling pin to roll out to about ¼" thickness.
- Lightly flour your star cookie cutters and cut out your shapes, transferring them to ungreased cookie sheet.
- Once you have cut out all of the shapes that you can, be sure to re-combine the scraps and roll out and cut out again to get the maximum number of cookies from your dough.
- Bake on 350F for 10-12 minutes (longer if you are using larger cookie cutters) and allow cookies to cool completely before dipping
Glaze
- In a large bowl, combine sifted powdered sugar, 3 Tbsp milk, and light corn syrup. Whisk until smooth. If mixture is too dry, add additional milk, one teaspoon at a time until mixture can be stirred.3 cups (375 g) powdered sugar, 3-4 Tbsp milk, 3 Tbsp light corn syrup
- Stir in extracts (be sure to taste test to ensure you are happy with the flavor!)½ tsp vanilla, ¼ tsp almond extract
- Glaze should be thick, to test that it is the right consistency drop a few droplets on top of a test cookie. If the glaze remains stiff, it needs to be thinned. If it runs off the cookie, it is too thin and needs more powdered sugar. If it settles down smoothly, it is just right.
- Divide glaze into four small bowls.
- Working with one bowl at a time, use a toothpick (a different toothpick for each color) and dip it into the food coloring bottle and then into the glaze. You want a small pool of food coloring about the size of a mini chocolate chip or two.gel food coloring
- Drag a toothpick through the food coloring and glaze until it is prettily swirled (like a galaxy).
- Holding your cookie at the base, dip the surface of each cookie into the glaze (take a look at your first cookie -- are you satisfied with the pattern? Adjust whorls with additional food coloring as needed).
- Optional: Before glaze can harden, immediately after dipping sprinkle cookies with disco dust and silver stars. These make them look extra pretty but are not required for stunning cookies.
- Once the first bowl runs out or the colors become too muddled together from dipping, move onto your next bowl of food coloring (you will probably need to stir as the surface may have begun to harden).
- Repeat steps 5-7 until all cookies have been dipped. Allow them to harden at least 30 minutes (may take longer) for glaze to set. Enjoy!
- Keep uneaten cookies in an airtight container at room temperature.

I’m not adding a rating b/c I didn’t actually make the cookies – just the glaze. The glaze was great! In the past I had trouble making a glaze that hardened so I could bag the cookies up or stack them – this glaze hardened up in about an hour and a half (I put a thick layer… plus it’s humid here). The galaxy design looks so cute and my daughter loves it for her space themed birthday. I appreciate all the tips about how to do it. We were able to top about 8 cookies per bowl. Very cute and easy to do and of course it tastes great!

We’re so glad they turned out so nicely, Suzanne! Thanks for using our recipe 🙂

If I wanna halve this recipe should I still use one egg yolk or should I halve the egg yolk. I have extra egg yolks from making macarons so it’s not a huge deal to do so but I’d rather use a whole one. These look great and I wanna make them but don’t need 60 cookies.
Sam
Hi Abby! I would scramble the yolk and use half of it. 🙂

Beautiful cookies! I just used your glaze (on another cookie) and it worked really well, plus it was fun! I flavored it with orange extract (Penzey’s) – maybe 1 1/2 or 2 t. I did a small trial glaze first with orange juice and rind – but it turned the glaze orange – not very galactic – so I used the extract alone. My “learning experience” is that next time, I will swirl more coloring in. I left a lot of white, per your comment, and didn’t think to check back until I was done, and although my cookies look good, your blue/purple cookies look more “spacey” and stunning. And, mine will, next time 🙂 Thanks for the recipe!
Sam
I’m so glad you enjoyed it so much, Lori! 🙂

Am I able to use regular cocoa powder instead of dark cocoa powder? Thanks!
Sam
That should work fine for these cookies. Enjoy! 🙂
Donna
Can you cut out stars & bake them then freeze for 2 weeks? Thaw at room temperature & then put icing on?
Sam
Hi Donna! That should work just fine. 🙂
Ana
Hi!
I’d like to make this recipe but I can’t seem to find light corn syrup anywhere… Can I skip it or should I use some substitute?
Thanks in advance!
Sam
Hi Ana! I believe it is called glucose syrup or golden syrup in countries outside of the US. Unfortunately if you can’t find any of those I’m not sure what a good substitute will be. 🙁
Shauna Farris
I made a simple syrup with 1 cup sugar and 1/4 cup water, dissolved over low heat on the stove. It worked great!
Patti
Thank you so much for this recipe. It’s awesome. I also made your sugar cookie and used this same idea for the frosting. I did red, white and blue for the upcoming 4th of July. So beautiful. Your recipes are always amazing. I appreciate your tips as well. Keep baking!
Sugar Spun Run
Thank you so much, Patti! I have a star-spangled cookie recipe that uses this same technique. I am happy they turned out so well for you and that you had fun making them. 🙂
Ranjita
Hi!
I would love to try this recipe for my daughter’s birthday this month.
Firstly, I would just like to know if I could use Icing Sugar for the glaze?
Secondly, could I use Castor Sugar for the cookies as it’s super fine & would be so much easier to blend in with the butter?
Please do clarify. Thank you so much!
Love from India💕
Sam
Hi Ranjita! Icing sugar is the same as powdered sugar so yes that will work just fine. The castor sugar will also work. Happy early birthday to your daughter! I hope she loves the cookies. 🙂
Mark
This recipe is incredible! The base cookie is delicious on its own and the icing instructions you gave made for an amazing pattern. So happy with how these cookies turned out!!! You’re a genius
Sugar Spun Run
Thank you so much, Mark! I am so glad that you enjoyed the galaxy cookies! Thanks for trying my recipe and for commenting. 🙂

Have you tried making and glazing the cookies well in advance of an event and freezing them? If so, when you thaw a room temperature, does the glaze run? I’ve not had a problem in the past with royal-iced-and-frozen cookies running when thawed to room temp, but wondered if these would.
Sam
Hi Keren! I have not, I think if you allow the glaze to set completely before freezing they should be fine, though.
