Double Chocolate Graham Cracker Chip Bars

Preheat oven to 375 °F (190°C). Grease a 13 x 9 x 2-inch pan.

Combine graham cracker crumbs, flour and baking soda in a medium bowl.

In a large bowl, beat butter and sugar with an electric mixer on medium speed until fluffy. Add eggs, one at a time, beating well after each addition. Stir in vanilla. Mix in flour mixture, in increments, on low speed until combined. Stir in chips by hand. Spread mixture into prepared pan.

Bake 18 to 20 minutes. Cool completely on a wire rack before cutting into bars.
