In a hot skillet melt the butter, on medium heat. Then add the sugar.
At this time you might want to go ahead and started with the sandwich. Take the two pieces of bread and make a peanut butter and jelly sandwich.
When the sugar finally turns to caramel, swab both sides of the bread with the caramel. Set the sandwich down in the skillet for a few minutes on each side...till the outside of the sandwich is crunchy, crispy and nummy. Then finish it off with a sprinkle of powdered sugar and a cold glass of milk.
