I was trying out a rock candy recipe for our Breaking Bad costume and it turned out green instead of blue. A whole pans worth of candy and I didn’t know what to do with it. I had signed up for a dessert for our Halloween party and had planned on making blood splattered cookies. The green broken rock candy looked very similar to sea glass so I thought I’d add them to the cookies to give them a little more pizazz. Plus my Oreo dipping was not very clean so anything to hide the messy job was good with me! ­čśë

The rock candy recipe comes from The Cookie Rookie. I was actually making it for our Breaking Bad costumes but it came out green instead of blue. I then realized the Blue Raspberry Imitation had a small yellow tint which is why the two toothpick dips of blue weren’t enough.

Glass Rock Candy


  • 1/2 cup water
  • 3/4 cup light corn syrup
  • 2 cups sugar
  • 2 tsp flavoring extract (I used raspberry imitation, which had a yellow tint)
  • Blue food coloring (just two dipped toothpicks full)
  • Candy Thermometer


  1. Mix all ingredients together and place in a medium saucepan.
  2. Stir until boiling.
  3. After liquid begins to boil, do not stir until finished.
  4. Once boiling, place the candy thermometer in liquid and monitor closely. When the liquid reaches 300º, take off heat and set aside.
  5. Wait until bubbles quick breaking at the surface and pour onto a foil-lined baking sheet.
  6. Leave until fully hardened. You can break apart to the size desired with a meat mallet.


Tip: To keep them from sticking, shake them in powdered sugar before sealing in an airtight container!

For the red frosting, I used powdered sugar and enough milk to make it the consistency I wanted and then played with the red and blue food coloring until it was a dark red. It ended up being around 4 toothpick dips of red and one blue dip. I think the gel is better to use than the simple liquid food coloring, I added the ones I used at the bottom of the post.

Bloody Glass Cookie


  • Pack of Double Stuffed Oreos
  • Bag of White Chocolate
  • Glass Rock Candy (see recipe above)
  • Blue food coloring
  • Red food coloring
  • Powdered Sugar
  • Milk


  1. Once your glass rock candy has dried and been broken down to the right size, you can set aside.
  2. Mix powdered sugar and milk in a small bowl. Add in a tiny bit of blue food coloring (I did 1 toothpick dip of blue) and a lot of red (about 4 toothpick dips). Play until you get a color and consistency you like!
  3. Take your Oreos and dip them in the melted white chocolate until completely covered. Make sure to get double stuffed so you can stick a toothpick between for easy dipping. If toothpicks aren't working for you, lay them on a cookie dryer sheet and pour chocolate over the top, flip and repeat.
  4. While white chocolate is hardening, take the glass rock candy and arrange them on the cookie.
  5. Get a 1/4 teaspoon and splatter or pour red frosting to your desire. This is the fun part!
  6. Allow to fully dry and enjoy!

I think next time I will try double stuffed or just drop the Oreo’s in a small bowl to make sure they were completely covered. Luckily messy works with this type of cookie!

It was actually really fun finding places to stick the glass candy in and then dropping the red frosting around. A little too much fun maybe haha. They turned out so realistic and they will be a hit at your next Halloween party!
