The best Sugar Cookie Icing has been a tried and true recipe in our family for years. Without fail, no class party would go by without my mom’s famous cut out sugar cookies making an appearance. Teachers might have highly requested them, but I think Mom made them year after year because I could be trusted transporting them to school.
This sugar cookie icing recipe hardens into a beautiful glassy surface that’s durable enough to be stacked, wrapped, or transported on a bumpy bus ride. It’s like a sugar force field for cookies.
(Now that I’m pondering it…that’s most likely why Mom sent us with homemade peanut brittle and caramel corn for teacher’s gifts. They’re also delicious and durable!)
How Do You Make Cookie Icing That Hardens?
The trick to getting sugar cookie icing to harden is in the ingredients, powdered sugar, milk, and corn syrup. The extract adds a boost of flavor. The small amount of corn syrup achieves that shiny, glossy surface.
Since there is no butter or fat in the recipe, this icing will harden similar to royal frosting. But, unlike royal frosting, the ingredients are simple, and this frosting impressively is made in only 5 minutes.
How To Make Sugar Cookie Icing
- Sift powder sugar into a bowl.
- Add corn syrup, extract, and milk.
- Stir ingredients vigorously until no lumps remain. If making colored icing, divide into bowls and add food coloring.
- To frost cookies, pipe an outline around the edge of the cookie. Fill in outline with icing.
TIPS FOR MAKING SUGAR COOKING ICINGÂ AND DECORATING
- Start with a couple teaspoons less of milk. Add the last 2 teaspoons as necessary.
- To achieve the perfect consistency add more powdered sugar to thicken and a touch of milk to thin.
- You’ve reached the correct consistency for frosting if a scoop of icing slowly falls off the spoon.
- Traditionally sugar cookie icing is flavored with almond or vanilla extract, but orange, lemon, maple, or coconut extracts can also be substituted.
- Sifting the powder sugar before adding milk will eliminate any potential lumps in the frosting.
- Pipe an outline of icing and fill in for pristine edges. Alternatively spread it on with a small knife and decorate with sprinkles.
- This frosting hardens quickly so have sprinkles ready to put on immediately.
- Before stacking or wrapping cookies, make sure the icing is completely hard. Set cookies on a baking sheet for 12 hours.

Liane Coleman says
This was a massive fail. By the time I added enough sugar for the icing to be somewhat thick, it tasted terrible – like I was eating straight powdered sugar. It does look nice and glossy but the taste was just not good.
Becky Schafer says
I love this recipe! So much better than royal icing. I always pop the bubbles on the tops of the cookies after I flood the icing. However, once dry, spots that looked like popped bubbles appear. Do you know what causes this?
Ann says
A friend shared this recipe after I admired her cookies. However, when I frosted my sugar cookies, the frosting mottled – sort of marbled looking – after they dried. Any idea what caused this? Thanks!
Christa says
Because of the milk do the cookies have to be refrigerated after they set up? Or are they ok at room temp? And for how long? I need to be able to ship some cookies. Thank you!!
Real Housemoms JK says
Hey Christa! I would put the cookies in an air tight container and would last several days at room temperature!
Kimber Hershberger says
How long does the icing stay shiny on the cookies? I’ve tried some recipes and after a day it looks dull.
Genna says
Can this be used for constructing gingerbread houses?
Real Housemoms JK says
Hello Genna! Here is a different recipe for gingerbread house icing that would work better. Enjoy! https://realhousemoms.com/the-best-gingerbread-icing/
norma sullivan says

Happt holidays to you and family ——-stay safe ——-norma
Angie says
I’m hoping to make this tomorrow. I have 2 questions. Do you pack the powdered sugar and how many cookies will this recipe frost? Thank you for sharing this!!
Real Housemoms JK says
Hey Angie! The powdered sugar is sifted, not packed. And this recipe should make about 34 cookies. Enjoy!
Colleen says
Once cookies are iced, can you freeze them? Or will that wreck the icing?
Real Housemoms JK says
Sure Colleen! I do this all the time!
Terri says
Can you make the icing in advance and refrigerate it will it set up too much?
Real Housemoms JK says
Hey Terri, you should be able to store the icing in a sealed container in the frig but make sure you let it get back to room temperature before using.
Shelley says
Should the powdered sugar be sifted before or after measuring?
Real Housemoms JK says
Hey Shelley! I measure before sifting. Hope this helps!
Sharon Schumacher says
I would like to make this icing a day or two ahead of time. I understand that it hardens quickly. I was wondering if I keep in airtight container would that work? Or is it best to make it immediately prior to frosting my cookies? THANK YOU
Real Housemoms JK says
Hey Sharon, you should be able to store it in an airtight container in the frig for several days. Just make sure you let it sit out a while before using it on your cookies so it can get closer to room temperature.
Asheton says
Would this icing be suitable for edible markers?
Aubrey says
Yes, you’d be able to use them just fine.
Katy says
Can this be made with almond milk? My son is highly allergic to cows milk.
Aubrey says
Yes, you should be ok with almond milk but I haven’t tried it myself. I don’t see any problem though.
Jessie Richards says
Will it work with alternative powdered sugars?
Aubrey says
I haven’t tried them myself but you should be able to use an alternative that says it is a one to one replacement for powdered sugar.
Meri says
Hello! I found this recipe wonderful!!! However I was wondering if you could substitute something for the corn syrup?? But thank you for this recipe it really helped me.
Jennifer Kimmel says
Hello Meri! Corn syrup is the best for achieving that shiny, glossy surface.

Mackenzie says
Wondering if you can use water (or other non-dairy liquid) instead of milk for this recipe?
Aubrey says
You should be able to use water for the recipe it will just have a different flavor.
Carol says
I did this recipe. Instead of vanilla or almond extract. I used real lemon juice I squeezed from a lemon. The flavor was great.
Aubrey Cota says
Wonderful! Lemon juice is one of my favorites for icing.
