1 (6 oz.) semi-sweet chocolate chips
1/4 c. butter
2 c. Bisquick baking mix
1 (14 oz.) sweetened condensed milk
1 egg, beaten
1 c. walnuts, chopped

Spray pan with vegetable oil. Melt chips and butter. Add baking mix, milk and egg; stir well. Add nuts. Put in 13 x 9 inch pan and bake at 350 degrees for 25 minutes.

HINT: Do all mixing by hand.

If using glass baking dish, decrease by 25 degree oven temperature and line outside of dish with aluminum foil. This will keep corners from drying out.
