Marbled Sugar Cookies with Metallic Splatter | Valentine’s Day Tutorial

Yesterday Kate shared some great tips for meal prepping and today I have a sugar cookie recipe + tutorial… balance is key right HAHA! With Valentine’s Day right around the corner, I wanted to test out a new marbling icing method I had seen on Pinterest, and after I made these reindeer sugar cookies, I knew I wanted to use that sugar cookie recipe again as soon as possible! I decided to do a mini tutorial and these Marbled Sugar Cookies with Metallic splatter were so easy to make and they would make the perfect treat for a work or school party, or as gifts for your loved ones.

Bake your Sugar Cookies

Start off by making your sugar cookies. For these heart cookies I used Jenny’s Cookies Sugar cookie recipe– you can find that here. I liked these even better the second time! The only thing I did differently was let the dough sit over night in the fridge.

Make your Royal Icing

I had only played around with Royal Icing once before and I struggled with it. This time I used a simpler recipe and it was the perfect consistency and tasted so good!

  • 3 ounces pasteurized egg whites
  • 1 t vanilla
  • 4 c powdered sugar


In your stand mixer, combine the egg whites and vanilla until frothy (about one minute). Then gradually add the powdered sugar on low speed. Once incorporated, turn the speed on high and beat until stiff peaks form (about 8-12 minutes).

How to Make a Marbled Cookie

For the marble effect, you will need at least two colors of royal icing (I used three). I separated my royal icing into three parts and had a white, pink, and coral pink color. Note: You will need mainly white, so keep that portion a little larger and put it in a bowl that is wide enough to dip your cookies in.

I poured each pink into a bag so they would be easy to drizzle into the white after I dipped each cookie. Drizzling the icing will make sure that the colors are distributed evenly. Then use a toothpick to swirl the colors together. You will do this after each cookie is dipped.

One at a time, place a cookie straight into the icing, covering the whole top. Be careful when lifting the cookie out, so you do not break it and then tap off the excess icing while cookie is still facing down. Flip the cookie over and lightly tap  so the icing lays flat. Use a clean toothpick to pop and smooth out air bubbles.

How to Add Metallic Splatter

This is an optional step that adds a fun pop to the cookie. You can find the Rolkem Super Gold I used online. (I bought mine a long time ago off Etsy and do not remember the shop name, Sorry!), BUT amazon also carries it. However, any edible glitter you have could work.

Pour some of your edible glitter into a container and add a few drops of water. Using a clean brush (mine is this one) mix them together.

When you have a watered down paint consistency, splatter onto your cookie.

How fun is that glitter! Love the sparkle it adds.
