Saltine Cracker Toffee

40 saltine crackers (or enough to line your pan)
1 cup unsalted butter
1 cup packed brown sugar
2 cups milk chocolate chips

1. Preheat oven to 400. Line a rimmed cookie sheet or a jelly roll pan with non-stick aluminum foil. Place crackers in a single layer  - it's ok if they overlap a tiny bit to get the pan covered!

2. In a small pot, combine sugar and butter. Melt over medium heat, then increase to medium-high and bring to a boil. Hold at a boil for 3 minutes. Mixture should be a deep caramel color. Immediately pour over crackers. Spread to make sure all crackers are covered completely.

3. Bake at 400 for 5 minutes. Crackers will look bubbly.

4. Remove from oven. Sprinkle chocolate chips over the top and return to oven for 1 minute. Remove from oven and spread melted chocolate over the crackers.

5. Allow to cool in the pan. (After about 45 minutes, I moved the whole pan into the freezer for about 90 minutes to harden completely.) When completely cool, break into pieces.
