Microwave Caramel

THIS CARAMEL IS ADDICTIVE AND THE EASIEST AND BEST CANDY I'VE EVER MADE. Please don't hate me! 

MICROWAVE CARAMEL
1 cup butter
1 cup White Sugar
1 cup Brown Sugar
1 cup Light Karo Syrup
1 can Sweetened Condensed Milk
In a large microwave safe bowl melt the butter for 1 minute. Remove from the microwave and add the rest of the ingredients. Mix well. Place back into the microwave and cook on high for 3 minutes. Take the bowl from the microwave and stir well. Continue cooking on high for an additional 3 minutes, remove and stir. Cook for 3 more minutes ( for a total of 9 mins.) Remove from the microwave, stir and pour into a lightly buttered 9 x 13 cookie sheet. Once caramel has set, wrap in wax paper and store in an air tight container.
**NOTE** If you want a caramel sauce, shorten the cooking time a couple of minutes...experiment with it. ENJOY!!!
