1 cup butter
1 cup sugar
1 cup brown sugar
1 cup light corn syrup
1 can sweetened condensed milk
1. Melt butter in saucepan over medium heat. Add the sugars and corn syrup, stirring constantly.
2. After the sugars are dissolved, add the can of sweetened condensed milk. Boil to soft ball stage (24o f) and then let it get a little hotter. The degrees and times can vary, so be careful not to overcook the caramel. It will harden very quickly if you have over cooked it.
3. Pour into a greased 9x13 pan and let sit for a couple of hours.
4. Cut caramels and keep in an airtight container.
