1 (10 3/4 ounce) pound cake, frozen
1/2 cup butter or margarine
1 cup light brown sugar, firmly packed
1 cup semisweet chocolate chips
1/2 cup chopped pecans or walnuts

Preheat oven to 350 degrees F.

Cut pound cake vertically into 10 equal-size slices. Arrange cake slices on a broiler rack; broil 8 to 10 inches from heat source, until lightly browned on each side. Or toast cake slices in a toaster oven until lightly browned.

Combine butter and brown sugar in a small saucepan; stir over moderate heat for 3 minutes. Arrange cake slices on an ungreased baking sheet. Spoon half the brown sugar mixture over cake slices, dividing evenly. Bake for 5 minutes. Remove from oven and sprinkle chocolate chips, nuts and remaining brown sugar mixture over cake slices; return to oven and bake 10 to 15 minutes, until chocolate melts. Remove from oven and spread melted chocolate evenly over slices. Cut each slice in half and allow to cool.

Makes 20 squares.
