• Preheat the oven to 350° to bake your graham cracker base.
• Lightly oil a 13" x 9" x 2" pan.

To make the base:

• I was taught in high school, the way to make crumbs was to put the graham crackers in a big baggie, seal and then roll with a rolling pin. Works great and I still do it but you can use the food processor if you prefer.
• Mix the graham cracker crumbs, ¼ cup sugar and melted butter together.
• Press evenly into your prepared pan.
• Bake at 350° for 8 minutes.
• While this is baking make the topping because you want to add the top as soon as you take the base out of the oven.

To make the topping:

• In a saucepan melt the butter and add the brown sugar.
• Bring to a slow boil and boil 1 minute. Stirring.
• Add the nuts and boil another minute.
• Spread the sugar and nut mixture over the hot baked base.
• Bake 15 more minutes.
• Remove from the oven and sprinkle the chocolate chips over the top. The chips will melt a bit, automatically, into the base.
• Let stand for 5 minutes.
• Cut into bars and let cool about 10 more minutes before removing from the bar.
• Cool completely on wire rack.
