Chocolate layer first 2 eggs 1 cup sugar 0.75 cup flour half cup chopped walnuts 0.125 tsp salt quarter cup cocoa half cup butter or margarine Beat 2 eggs 'til foamy. Add sugar, flour, nuts, and salt. Melt cocoa and butter together in saucepan. Add to egg mixture and blend well. Spread in greased 9 x 13 pan. Set aside. Butterscotch layer next half cup butter or margarine 1.5 cups brown sugar 2 eggs 2 tsp vanilla 1.5 cups flour quarter tsp salt half cup chopped walnuts Cream butter and brown sugar. Add eggs and vanilla. Beat until well mixed. Add flour, salt, and nuts. Spoon over chocolate layer in small blobs, and spread as best you can. Bake at 180ºC (or 180 C) for 30 minutes 'til brownies begin to pull away from pan. Note: I usually do it opposite so that I can use one bowl, and they're just as yummy. My family hates walnuts, so I never get to taste them in these, though I bet they would be wonderful (poor Mom ~she's always sacrificing -can't you just hear those violins playin'...). I bet just the butterscotch part would be yummy baked in a 9 x 9 or 8 x 8 pan. I'm going to go home and try it (maybe with walnuts) because that's my favorite part.
