Easy Praline Squares - cooking recipe

Ingredients

Graham crackers
1 cup firmly packed brown sugar
10 tablespoons butter
1/4 teaspoon cream of tartar
1 cup walnuts (original recipe called for finely chopped pecans, but the walnuts were heavenly)
1 large bar milk chocolate, such as Lindt, coarsely chopped (optional)

Preparation

Break enough graham crackers into individual rectangles to cover the bottom of a 15x10x1-inch jelly roll pan.
In a saucepan, bring brown sugar and butter to a boil.
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.
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.
