Black Forest Torte

Heat oven to 350?. Brush sides and bottom of four 9" round layer pans with butter. Bake only two layers at a time. Measure into a large mixer bowl all ingredients except eggs. Beat at low speed to blend; beat 2 minutes at medium speed, scraping bowl frequently. Add eggs; beat 2 minutes more. Pour 1/4 of batter into each pan; layers will be thin. Bake 15-18 minutes or until done. Cool slightly and remove from pan; cool thoroughly on greased waxed paper to prevent sticking. Alternate layers with chocolate filling and cream filling, ending with chocolate filling on top. Do not frost sides of torte.
