1/4 cup butter, melted
1 cup sugar
1/2 cup light corn syrup
1/2 cup sweetened condensed milk
1 teaspoon vanilla
pinch of sea salt, optional
1/4 cup chopped pecans, optional
Combine butter, sugar, corn syrup and milk in a 2-quart glass bowl. Microwave for 3 minutes, then stir. Microwave for 2 minutes, stir. Microwave for 2 more minutes, stir and add vanilla (and salt and nuts if desired). Pour into a buttered 8" square pan and chill for 20 minutes. Cut with a plastic knife.
These were actually pretty good. I don't think I took any pictures, but we tried rolling a piece of this caramel into a ball, sticking it on a pecan and drizzling it with melted chocolate and it made a delicious mini turtle. It was to see if this caramel recipe would work for making turtles that I actually tried it. (I just don't have success with caramels needing a candy thermometer.) I think it will, but we ran out of time to test that theory this year!
