Saltine cracker toffee, a.k.a. Christmas crack, is a quick and easy holiday treat with buttery toffee, melted white chocolate, and sweet-tart cranberries set on top of crispy salted crackers.
Prep. Preheat oven to 400ºF. Line a jelly roll pan with aluminum foil and grease it with cooking spray.
Start with the saltine crackers. Arrange the saltines over the greased foil, one next to another, in a single layer; set aside.
Make the caramel. In a small saucepan, combine the butter and light brown sugar. Cook over medium heat, stirring frequently, until the butter is melted. Increase heat to medium-high and bring to a boil; continue to cook, stirring frequently, until it turns a caramel color; about 1 minute.
Cover the crackers. Remove from heat and pour it over the crackers. The crackers will start to move around; use a rubber spatula to set them back in place. Bake in the oven for 4 to 5 minutes or until the mixture is bubbly.
Melt the chocolate. In the meantime, set up a double boiler and combine chopped chocolate chips and vegetable oil in the top bowl. Melt the chips, stirring constantly, until most of it has melted but remove from heat while a few lumps are still present. The chocolate will continue to melt while you continue to stir it.
Assemble. Remove the saltine toffee crackers from the oven. Pour HALF of the melted chocolate over the crackers and smooth it out with a knife; let it stand for 1 minute. Then, slowly pour the rest of the melted chocolate and smooth it out again using a knife or an offset spatula. Add dried cranberries on top.
Cool & serve. Place the Christmas crack into the freezer for 20 minutes, or until cold. Afterward, break it up into pieces for serving.
