12 whole graham crackers
1 c. butter
1/2 c. sugar
1 tsp. vanilla
Chocolate (chocolate chips, "melting" candy, Hershey bars, etc.)

Heat oven to 350 degrees. Line 15"x10" jelly roll pan with foil. Arrange crackers over bottom of prepared pan. In small saucepan, combine butter, sugar and vanilla. Bring to boil over medium heat; boil 2 minutes, stirring occasionally. Remove from heat; pour and spread evenly over crackers. Bake at 350 degrees for 15 to 18 minutes or until golden brown. Cool slightly; place chocolate on warm crackers to melt. When chocolate softens, spread evenly. Cool completely; break into brittle pieces.
