Cinnamon Rock Candy Recipe

"My mother made this hard cinnamon candy many times for us as kids," says Marganne Winter Oxley of Klamath Falls, Oregon. "Now I fix it for my own family and to give as gifts at Christmas."
TOTAL TIME: Prep: 20 min. Cook: 25 min. + cooling YIELD:32 servings


  • 1 cup water
  • 3-3/4 cups sugar
  • 1-1/4 cups light corn syrup
  • 1 teaspoon red liquid food coloring
  • 1 teaspoon cinnamon oil
  • 1/3 cup confectioners' sugar


  • 1. Line a 15-in. x 10-in. x 1-in. pan with foil; butter the foil and set aside. In a large heavy saucepan, combine water, sugar, corn syrup and food coloring. Bring to a boil over medium heat, stirring occasionally. Cover and cook for 3 minutes to dissolve sugar crystals.
  • 2. Uncover; cook on medium-high heat, without stirring, until a candy thermometer reads 300° (hard-crack stage), about 25 minutes. Remove from the heat; stir in cinnamon oil (keep face away from mixture as oil is very strong). Immediately pour onto prepared pan. Cool completely, about 45 minutes.
  • 3. Break the candy into pieces using the edge of a metal mallet. Sprinkle both sides of candy with confectioners' sugar. Store in airtight container. Yield: about 2 pounds.
Editor's Note: We recommend that you test your candy thermometer before each use by bringing water to a boil; the thermometer should read 212°. Adjust your recipe temperature up or down based on your test.

Recipe Note

Editor's Note: Cinnamon oil can be found in some pharmacies or at kitchen and cake decorating supply stores.

"This is the first time I have ever made rock candy and the recipe came out perfectly! I did add an additional tsp of cinnamon flavoring because I was using extract instead of oil. I was wondering if it would be a problem to double up on this recipe if you had two pans to pour it into?"

"I have made this so many time and my family just loves it!! The only thing that I changed is that I use a cookie sheet about 1/2 inch deep and spray the tray with none stick cooking spray to coat the cookie. After it cools, it pops out in one piece. My wife started using cooking scissors to cut it into squares before it cools all the way. This is so the pieces do not have sharp edges. Thanks so much for posting this recipe!!"

"I would use parchment instead of foil, and to prevent the candy from sticking together I would coat with powdered sugar."
