Ya'll may have tried these already..Very easy..
Take graham crackers and lay them on a cookie sheet with sides lined with foil... Melt 1 1/2 sticks of butter and one cup dark brown sugar...Bring to boil for about 5 minutes...pour over graham crackers...bake at 425 for about 5 minutes till starts to bubble..add toffee chips and place in freezer to cool...When cooled break into pieces...Oh my!... you could use Heath bar and pecans... If you like chocolate you could use some chocolate chips...Enjoy!
