I found this recipe in Belleman's Church Cookbook about 15 years ago. Been making them ever since. Fast and easy and little clean up.
Pralilne Graham Cracker Treats
¼ lb butter
½ c brown sugar
½ c chopped pecans (or walnuts are yummy too)
Line cookie tray with aluminum foil. Cover with graham crackers. Place butter and brown sugar in a saucepan and bring to a boil for two minutes. Pour over graham crackers, covering entire surface and sprinkle with chopped pecans.
Bake 8 min in preheated 350° oven. Remove and cut into squares immediately. Cool 2 hours and store in airtight container.
My kids eat them warm because they won't wait.
