Preheat oven to 350ºF.

Line cookie sheet with parchment paper, or greased tinfoil, or just grease a cookie sheet. Break up graham crackers into smaller crackers and place them on the prepared cookie sheet. Get as many crackers side-by-side as you can.

In a medium sauce pan, bring butter and sugar to boil and boil for three minutes, stirring constantly. Pour over graham crackers. Use a spoon to make sure all the crackers are coated. Sprinkle chopped pecans over top.

Bake for 10-12 minutes, until it gets bubbly and golden brown. Remove from oven and cool for 5 minutes. If you used parchment paper on your cookie sheet, you can allow the crackers to cool completely, and then store them in an air-tight container.
