Personalized Gold Coin Cookie Stamps for St. Patrick’s Day

By Lindsey Boardman

St. Patrick’s Day is nearly here, and you know your little leprechauns will be wanting to hoard some gold, so why not help them mint their own golden coin cookies with homemade custom cookie stamps!

[We have updated this to reflect a change. Upon further examination, I am not comfortable with us recommending polymer clay be used as a stamp for food. The directions are still below but they are to be used for non-food crafts. Use our salt dough stamp instead for cookies. ~ Isabel (3/14/13)]

Custom Cookie Stamp made from Salt Dough

I wanted to see if there was an easy way that the kids could make as many stamps as they wanted, so we experimented with making some stamps out of salt dough.

Salt dough “clay” is made from just one part hot water, one part salt and two parts plain all-purpose flour mixed together and kneaded into a smooth dough. The kids used a collection of small toys and interesting shaped objects from around the house to make their salt dough stamps.

I made them some handles from the salt dough that we could glue on once they were baked solid. The trick with salt dough is to bake it long and slow so that it doesn’t have any problems with air pockets distorting it. We left ours to air dry overnight and then I popped them in the oven on a low heat to finish them the next day.

Happily we found that the salt dough stamps worked nearly as well as the polymer clay one had! Although they are unlikely to last as long or be as easy to clean.

The cookie dough that we used for stamping was a basic sugar cookie recipe that we found on Sweetsugarbelle, but without the leavening ingredients (in this case, no baking powder was added). By not adding any raising agents to your dough you will be making your cookies less fluffy and crisper, but they will hold the stamped shapes a lot better. Shortbread dough also holds stamped patterns well.

The dough was rolled out to the thickness that we wanted the finished cookie to be, because very little rising would happen in the baking process, and the stamp was used to imprint the dough. Sometimes the kids made an uneven stamp, but they just cut out the ones they were happy with and re-rolled the rest of the dough to stamp again.

Something that we found did help a lot with getting the detail of the stamp to hold up through baking was putting the stamped and cut out cookies in the freezer for 20 minutes before putting them into the hot oven to bake.

Rather than adding yellow food coloring to the dough, when the cookies came out of the oven we brushed them with some beaten egg white that had been colored with yellow food coloring while they were still hot. To add even more of a golden sparkle, we gave the finished cookies a light spray with some metallic food coloring spray.

Of course, you don’t have to just use this technique to make golden coin or leprechaun cookies for St. Patrick’s Day, you could make/ imprint your own custom and personalized cookie stamps for any occasion or holiday. For example, personalized birth announcements done this way would be adorable!

I hope you feel inspired to have a go and create your own Personalized Family Cookie Stamps unique to you and your loved ones.


Custom (non-food) Stamp made from Polymer Clay

Polymer clay, such as Sculpey or Fimo, is the ideal material to craft your own customized stamps from, because it’s easy to work with and bakes hard and is easy to wash clean with soapy water to re-use. It can be found in a wide range of colors at most craft or hobby stores, for around $2 per packet. One packet is enough to make one complete custom stamp.

Our custom polymer clay stamp was made by rolling out half a packet of polymer clay to about a quarter inch thickness, and cutting a disk from it with a circular cookie cutter. The personalized imprint of our family name and date and the little four leaf clover were all made with a pencil, and then a circle of little dimples around the edge were added with the pencil point to make it look more like a coin. Remember that any writing you put on your stamp must be in mirror image!

The other half of the packet of polymer clay was used to make two shapes that could be glued onto the disk to use as a handle when stamping.

These were baked according to the instructions on the packet, and once cooled the three pieces were glued together with superglue. It’s important for safety reasons to bake clay according to package instructions. (Also, it’s good practice to always ventilate your area well when crafting.)

    Thanks for sharing this cute idea! And for commenting on my pin about the polymer clay – very nice of you. I think this would be so fun for a special party or just to do with kids for fun. Great Christmas cookie party potential too – and much less messy than icing everywhere!

    I looked into it a bit.  Polymer clay is non-toxic, but it’s considered not safe for food because it’s porous, making it difficult to sanitize properly.

    It seems to me that the salt-dough stamps would be an even worse choice for that reason. The only reason the salt-dough stamps might be a better choice is because you’ll be more likely to throw them away after one use.

      Thanks Ed for your thoughts on this. The issue for me is about the composition of polymer clay and that it contains PVC and phthalates. Even though the polymer clay you buy may be labeled non-toxic I don’t know enough about the risks. It’s about comfort level vis-a-vis potential risk.

    Diane and I used to play with cookie stamps when she was little.  And salt dough!  But combining both together – brilliant!

    Looks like we are going to have to schedule a play date!!!

    Thank you for sharing your very cool idea!

    Why you don’t recommend using the polymer clay stamp on food?

      we’re uncomfortable recommending that it is a “food-safe item” if it is made from polymer clay. There’s a lot of written information on the internet about it. You can make your own decision after reading it. But we have taken this position. 🙂

    Hi, Are you putting the raw egg white wash on cookies that are going to be eaten ? Or are they more of an ornament ? From the egg food safety ?
    Thanks . 🙂

    Could you not use cling film as a barrier between the stamp and the cookie dough?
    Is it not thin enough to get a good print yet keep the clay from touching the food?
    Plus it’s disposable so can be thrown once you’ve finished stamping and keeps your stamp clean

    I love this. But I did have one question. How do you deal with the issue of clay displacement? A problem I’m having with it are, when I draw something, the clay that I move out of the way builds up on the side of the design and makes the stamp uneven. When I try to flatten it out again, some of it closes over the hole, but there’s not enough moved out to just remove it. The other problem is that when I try to make an imprint in the clay with something, it partially flattens and spread the stamp which makes it misshapen and uneven.

    did you ever come across this issue and if so what did you do to rectify it?
