Mermaid Icebox Cookies!

By Brenda Ponnay

We are deeply into all things mermaids this summer at our house so we decided to make some mermaid-inspired icebox cookies. Is there such a thing as a mermaid colors? Well, my girls seem to think so… they think pink and teal.  They also believe in “unicorn colors” (ROYGBIV). You can make striped icebox cookies with any colors (not just the ones we chose, obviously) with these easy steps below!

Supplies you’ll need to make Mermaid Icebox Cookies

  • two batches of your favorite sugar cookie dough. (We used this recipe.)
  • food coloring
  • a loaf pan lined with wax paper
  • a spoon
  • plastic wrap or tinfoil
  • mermaid tail cookie cutter (optional)
  • and of course an oven, a refrigerator and cookie sheets

How to make Mermaid Icebox Cookies

First make your dough. Color each batch a different color. For our teal-colored dough we used seven drops of blue food coloring and five of green but you can use any food coloring you like, even natural food coloring. For the purple we used four drops of neon pink food coloring, one drop of red and one drop of blue. We mixed the coloring in throughly with a mixer to avoid getting our hands dyed.

Then we lined our loaf pan with wax paper and started with our first layer of teal dough. Spoon in about an inch of dough and smooth it down inside the loaf pan with a spoon. Then we added purple and did the same thing. Repeat until you’ve filled the loaf pan all the way to the top with even layers of dough.

Pop it in the refrigerator for an hour or more! This step is crucial.

Once our dough was good and chilled we turned our loaf pan upside down onto a cutting board and sliced it in half with a knife (use your common sense and judgment; if your kid is too young to handle, an adult should handle this step and the knife) so that we had two long rectangles. We trimmed off some of the edges to make them nice and sharp on the edges. Then we sliced our long rectangles into individual cookies and placed them onto a cookie sheet.

They looked so cute all spread out on the cookie sheet. Make sure to allow enough room in between each cookie because they will rise and spread when they bake.

Then we baked them per the sugar cookie dough recipe.

They are called icebox cookies because you can keep the dough in the refrigerator aka icebox. You can make them anytime you like just take your chilled dough out of the refrigerator and slice up how ever many cookies you like. You can even freeze the dough and make them months later!
