Easy Praline Squares

Directions

1. 1
   Break enough graham crackers into individual rectangles to cover the bottom of a 15x10x1-inch jelly roll pan.
2. 2
   In a saucepan, bring brown sugar and butter to a boil.
3. 3
   Add cream of tartar and walnuts (or pecans) to the boiling mixture. Pour over graham crackers and spread as evenly as you can (it's a pretty thick mixture so it's best if you only spread one way rather than going back and forth). Scatter the chocolate on top, if you've chosen to add it.
4. 4
   Bake in a 325 degree F oven for 10-15 minutes, or until the chocolate has gotten melty and the sugar mixture is lightly bubbling. Remove from the pan while still warm.
