Makes one 8x12 inch pan, approximately 48 1x2-inch bars; adapted from Carrie Brown's Jimtown Store recipe
Preheat oven to 200° F. Line an 8x12-inch baking pan with a piece of baking parchment, leaving a ½ inch overhang on opposite sides so you can use it to lift out the baked and cooled bars.
Mix all ingredients together and spread into prepared pan. Bake for 1 hour, until lightly browned and dry to the touch. Do not overbake.
Cool to room temperatures then transfer pan to the refrigerator to chill overnight for easier cutting.
After chilling, lift the slab out of the pan by the parchment edges, transfer to a cutting board and with a very sharp knife, cut into bars. Wrap individually in parchment or plastic wrap.
