Pop into a well-greased 8 x 8” baking pan and push it around until it is evenly distributed.
Bake at 350° for 20 minutes or until the edges are browned and just start pulling away from the pan.
Cool at least an hour but not more than 3 hours before cutting into ¾” squares.
You need to cut them while the chocolate bits are still softish because if you wait until the chocolate hardens up completely, they become difficult to cut.
