1/2 c. butter, softened
1 pkg. Betty Crocker white cake mix
2 (21 oz.) cans cherry pie filling
1/2 c. chopped walnuts

Heat oven to 350 degrees. Cut butter into cake mix (dry) until crumbly; reserve 1 1/2 cups mixture. Pat remaining mixture lightly in ungreased oblong pan, 13"x9"x2", building up 1/2" edges. Spread pie filling on cake mixture to within 1/2" of edges. Mix walnuts and the reserved mixture; sprinkle on top. Bake 45 to 50 minutes. Serve warm and, if desired, with whipped cream or ice cream. 12 to 15 servings.
