9 inch unbaked pastry shell
1 c. semi-sweet chocolate chips
1/4 c. butter
1 (14 oz.) can sweetened condensed milk (not evaporated milk)
1/2 c. all-purpose baking mix
2 eggs
1 tsp. vanilla extract
1 c. chopped nuts

Heat oven to 375 degrees. Bake pastry shell 10 minutes; remove from oven. Reduce oven temperature to 325 degrees.

In saucepan over very low heat, melt chips with butter. In large mixer bowl, beat chocolate mixture with remaining ingredients, except nuts, until smooth. Stir in nuts. Pour into prepared pastry shell. Bake 35 to 45 minutes or until center is set. Cool. Serve warm or at room temperature with ice cream, if desired.
