chocolate chips + shortening(for drizzle on top, optional... see NOTES below)
Instructions
MAKE THE BARS:
Preheat the oven to 350°F. Grease and flour an 11x7-inch pan (You can use a 9x9-inch pan, but the baking time will be longer).
In a 2-quart saucepan, heat the butter and baking chips over low heat, stirring frequently, just until melted and smooth (the mixture may appear curdled). Remove from heat; cool.
Stir in the remaining bar ingredients until well blended. Spread evenly in the pan.
Bake 30 to 35 minutes or until a toothpick inserted into the center comes out clean. Cool completely.
Run a knife around the edge of the pan. The whole thing should pop out of the pan pretty easily- pop onto a cutting board and carefully turn upright.
ADD THE ICING:
In a medium bowl, use an electric mixer to combine all of the glaze ingredients (start with 1 tablespoon of the milk, and add more as needed) until smooth and spreadable. Spread the icing over the bars. Let cool. (optional: drizzle chocolate patterns on top if you'd like.) Let cool completely before cutting. They'll cut into neater squares if the bars have been chilled for a while.
Notes
*If you'd like to add a chocolate drizzle, melt about 1/2 cup chocolate chips with about 1 teaspoon of shortening. Microwave and stir until smooth. Pour into a small zip top baggie, snip the end and drizzle away into your desired pattern.
