Easy Microwave Caramels

1 C brown sugar
1 C white sugar
1 C white karo syrup
1/2 lb (2 sticks) melted butter
1 14oz can sweetened condensed milk

Combine all ingredients in a large glass microwaveable bowl (2 qt.) and mix well with a wire whisk. Place bowl in microwave and cook on high for 7 minutes. Remove bowl from microwave and stir ingredients very well one more time. Put bowl back in microwave and cook another 7 minutes on high. Pour bubbling hot caramel mixture into a buttered 9 x 13 pan and let it cool completely. Cut into narrow rectangular pieces and wrap in wax paper. One batch makes about 150 caramels, depending on the size you cut it.

I've tried this on 3 different microwaves and they always turn out great for me.
