Cooking spray
About 35 to 40 saltine crackers
2 cubes (1 cup) butter
1 c light brown sugar
1 pkg semisweet chocolate chips
Preheat the oven to 425 degrees. Line a large jellyroll pan with aluminum foil, spray with nonstick spray and arrange saltines in a single layer. In a medium saucepan, melt the butter and brown sugar together and boil for about 2-3 minutes. Remove from the heat and pour over the crackers, covering them evenly. Put the pan into the oven and bake for 2 to 4 minutes, or until just bubbly, watching carefully. Remove from the oven and pour the chocolate chips over the crackers. When the chips melt a bit, spread them over the crackers with a knife. Transfer the pan to the freezer for 15 to 20 minutes, or until completely cold. They will form one big sheet. Break up into pieces. Store in an airtight container.
