Broiler Carmel Toast (not SB friendly)

I got this recipe when I was in 7th grade Home Economics cooking class. Its really simple and the kids I baby sat for really enjoyed it.

4 slices of bread
2 T butter or margarine
2 T brown sugar

Place bread slices on a baking sheet and toast one side in a toasting oven or broiler. Meanwhile, cream butter and brown sugar until smooth and set aside. When the bread is toasted take out and turn over each slice. Spread carmel mixture on the untoasted side making sure to spread it to the edges. Put the bread back in the broiler until carmel mixture is melted and bubbly. Remove from the oven and Enjoy!
