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.

Hi Sam, can the glaze harden in the fridge? Because i have a cooking exam about cookies and i want to use this glaze but theree is no time to make the glaze on the exam day. I want to make it in the morning or the previous night. But im wondering if i put the bowl of glaze in the fridge, will it harden?
Sam
Hi Alicia! Unfortunately it probably will. 🙁 Would you have time to make the glaze while the cookies bake? It should only take a few seconds to whip it together. Good luck! 🙂
Alice
I don’t know what you mean about the chocolate flavor not being strong. Those were incredible, and I’m a major chocoholic and chocolate snob! It was like a brownie shortbread. My only complaint is that is was tricky glazing something a little crumbly.
Sam
I am so glad you enjoyed the cookies so much, Alice! 🙂
Pat
very excited about making these
Since food coloring stains so much, should we use gloves when dipping cookies? or tongs?
I want to let kids dip the cookies
thanks
Sam
Hi Pat! I don’t use gloves when dipping and haven’t really had any issues, but you can certainly use gloves if you’d like. You will want to do it over wax paper so your counter top doesn’t get covered in food coloring though. 🙂
Tina
When you did the cookie do you twist it or just dip?
Sam
Hi Tina! I dip it in and wiggle it a bit to make sure it gets a nice coating and then just lift the cookie out of the glaze. You may need to twist as you lift and flip to prevent icing from falling all over the place. I hope this helps. 🙂

Could you pipe words on the surface after they dry?
Sam
Sure I don’t see why not 🙂
Joanie
What makes the frosting g get hard though ?
Sam
Hi Joanie! The sugar and allowing it to set and dry at room temperature allow the icing to get hard.
Joni
1 batch of cookie dough came out too crumbly the 2 no batch came out like fudge. What did I do wrong???
Sam
Hi Joni, I’m not really sure why they would come out so differently, that’s really strange! Could something have been mis-measured? What did you do differently with each batch?
Laura
Hi Sam does this glaze really harden? Looking to make these as wedding favors for under the star theme but will need to wrap or put in cellophane so just wonderimg if the glaze hardens to where it won’t make a mess?
Sam
Yes! it hardens, but does take several hours (ideally let them dry overnight).
Shelly Wood
I made heart shaped cookies for Valentine’s Day, and used coconut extract instead of the almond. They were delicious and so unique!
Jen
These are beautiful! I was thinking of using your glaze to top some orange zest and cardamom sugar cookies – do you think I could use orange juice in place of the milk in the glaze? I would love to make the glaze orange flavored and I really dislike citrus extracts. Thanks!
Sam
Ooh, I’m not sure, to be honest… Hmm, I worry that if you use orange juice instead of milk the glaze will be very thin, though you could potentially add more powdered sugar to combat that. Since I haven’t tried it myself it’s hard to be certain but I think it’s worth trying out, and if you do I’d love to know how it turns out for you!
Jeannie
Made these for my cookie exchange today; turned out perfect! Thank you for sharing your tips, tricks and recipe. They are simply beautiful!
Gabriella
I made your recepie for my son school event (space themed). The recepie is great and the cookies are beautiful. It was very easy and the galzing part was just so much fun.
Thank you for the recepie.
Sam
I’m so glad that you enjoyed it, Gabriella! Thank you for coming back and letting me know how it turned out for you! 🙂
Michelle
These look great. I’m just wondering how long the cookies last? I’m looking for something I can make a couple of days in advance. Thanks
Sam
These should keep about two weeks, store in an airtight container. I hope you love them!
Barbara R
Can you use this icing with cupcakes? I want a shiny hard thin frosting for cupcakes.
Thanks for the recipe.
Sam
I haven’t tried it that way but think it could work so long as the top of the cupcake is firm enough, if it’s a very soft delicate cupcake the top might come off in the icing so I would just watch out for that! I hope that helps!

Are the stars edible? or just some thing you added?
Sam
They are! I got them from my local cake shop but there is an affiliate link for them on Amazon beneath the post (the gold ones are cheaper on Amazon if you can find them, they’re expensive!).
