Preheat oven to 350.

Mix together all bar ingredients and evenly press into the bottom of a 13" x 9" baking pan.

Bake at 350 for 15 minutes; remove from oven.

For topping: Melt the chocolate in a sauce pan over low heat; gradually stir in the heavy cream; mix until well-combined. Spread this mixture evenly over the baked bars in the pan.

Allow to cool completely before cutting into squares.
