This recipe is made to perfectly fit on one average sized cookie sheet AND it uses the same numbers for recipe quantities and timing to make it an easy to remember recipe if you want to make multiple batches without going back to your phone or print out. You can easily double the recipe if you have more cookie sheets and oven space! And remember, no candy thermometer needed… score!
Preheat your oven to 300°. Line a cookie sheet with a silicone mat or parchment paper.
Pop 1/4 cup of corn into a large bowl to yield in between 4-5 cups of popcorn.
In a small saucepan melt butter in light Karo syrup over low heat. Once fully melted, stir well to incorporate.
Add in brown sugar and Jello powder to the saucepan and stir well. If adding in food coloring do that now. Raise the heat to medium-high and bring the mixture to a boil.
Reduce heat to medium-low so that the candy bubbles slightly. Set your timer for 5 minutes and walk away.
Tossing your popcorn as you go, pour the melted candy over the corn in the large bowl. Stir to coat well.
Transfer to your lined baking sheet and bake 5 minutes.
Remove from heat and allow to cool. Break into pieces to serve.
