Best-Loved Chocolate Bars
1 chocolate cake mix
1 cup graham cracker crumbs
1/2 cup peanut butter
1 egg
3 Tbsp half and half
1 (8 oz) package cream cheese, softened
1 jar (11.75 oz) hot fudge ice cream topping
1 package (12 oz) milk chocolate chips
1 cup salted peanuts

In a bowl, combine the dry cake mix and cracker crumbs. Cut in peanut butter until mixture resembles coarse crumbs. In a bowl, whisk the egg and cream. Add to the crumb mixture just until moistened. Set aside 3/4 cup for topping. Press the remaining crumb mixture into a greased 9x13 baking pan.
In a mixing bowl, beat cream cheese until smooth. Add fudge topping; mix well. Spread over the crust. Sprinkle with chocolate chips, peanuts and reserved crumb mixture. Bake at 350° for 25-30 minutes or until set. Cool on a wire rack. Cover and refrigerate at least 4 hours. Cut into bars. Refrigerate leftovers.
(I only had chocolate graham crackers so I used those instead of regular ones. It was very chocolate-y, to say the least.)
