Grease an 8x8-inch dish with butter, then set aside.
In a large microwave-safe bowl, add all ingredients and stir to combine.
Heat in microwave for 5-7 minutes, stirring every minute and a half. When approaching the last couple minutes use a candy thermometer to monitor temperature, when it reaches 250 it is done.
Pour caramel into the prepared dish and allow it to fully cool to room temperature.
Once cooled, use a greased knife to cut into bite-sized portions.
