Sugar Glass

Sugar Glass

The look of real glass with a delicious taste! Learn how to combine four simple ingredients to create a glass-like candy you can use to create and build edible works of art at home.


  • Medium Saucepan
  • Spoon
  • Baking Tray 
  • Non-Stick Cooking Spray 
  • Candy Thermometer
  • Oven Mitts


  • 2 cups of Granulated White Sugar
  • ¾ Cup of Water
  • ⅔ Cup of Light Corn Syrup
  • Pinch of Cream of Tartar
  • Food Coloring

Step 1: Prepare a sheet pan by spraying it with non-stick cooking spray. 

Step 2: Mix sugar, corn syrup, water, and cream of tartar in a medium saucepan and bring to a boil over medium heat. 

Step 3: Insert the candy thermometer and allow the mixture to reach 195 degrees Fahrenheit. 

*Tip: If a candy thermometer is not available, you might tell the candy has reached the correct temperature when it starts to turn yellow. Another trick is to test the candy’s readiness by dropping a spoonful of the mixture into a bowl of ice-cold water. By doing this, the candy will immediately form brittle strands. 

Step 4: Once the mixture reaches 195 degrees Fahrenheit, add a few drops of food coloring. Remove from the heat and pour it on the sheet pan. Careful, it will be scorching hot!

Step 5: Allow it to cool until hardened, approximately one to two hours. 

Step 6: Once cooled, crack your sugar glass candy by lifting the pan straight up and dropping it or gently hitting it using the back of a spoon. 

Ideas to take your sugar glass to the next level:

  • Use your sugar glass pieces to create small sculptures or use them as small windows for edible houses. Apply a thin layer of royal icing around the edges to help keep the pieces joined together.  
  • A couple of drops of food dye will change your clear glass into a vibrant creation. Watch this video to see how to create a multicolored effect. 
  • Add flavor to your sugar glass by including a few drops of flavoring oil.
