This was such a fun and easy last minute cake decoration! The “icicles” can be place on the top of any cake or cupcake or pressed into frosting around the side. We made an angel food cake so our frosting was whipped cream, which looked really pretty with the ice.
To make the glass you just boil sugar, water, and clear corn syrup to a “hard crack” (300 degrees on a candy thermometer) and pour onto a greased cookie sheet to cool and harden. It takes about 10-15 minutes to boil and about 30 minutes to harden depending on its thickness.
You will need:
a cookie sheet or jelly roll
cooking spray (I used wax paper instead per some bloggers’ instructions which I wouldn’t recommend, it ended up sticking to the glass and I had to peel it off)
1 3/4 cups of sugar
1 cup of water
1/4 cup of clear corn syrup
Combine sugar, water, and corn syrup in a heavy saucepan. Make sure the sides are tall enough to contain the mixture once it starts to boil up. Bring to boil over medium-high heat stirring often to make sure the sugar dissolves. Reduce to medium. Let the mixture boil away stirring occasionally. It will eventually become a thicker, syrupy texture. This is what you want. The color is going to caramelize a bit, which is fine since you will add food coloring later. If you have a candy thermometer, let it boil until it reaches 300 degrees. If you don’t (since we were at the lake house for our Frozen birthday party I did not), you can test to see if it’s done in a cold water bath. Have a clear bowl of ice water next to the stove, and when the mixture starts to thicken occasionally drizzle a strand into the water. If the strand sinks to the bottom and is still mushy or sticky when you try to pick it up it’s not ready yet. If you pick up the strand and it holds it’s shape and snaps and breaks when you squeeze it the mixture is ready. Remove the pan from the heat. At this point you can add food coloring and/or flavoring. Since our kids are little and we wouldn’t be eating it, I just added 3 or 4 drops of blue food coloring. Stir to combine and immediately pour out onto sprayed cookie sheet. I poured my excess into a small cardboard box so I could throw it in the trash rather than risk dumping it down the drain. Let the glass cool and harden on the cookie sheet. When its ready, pick it up and break it into pieces.
