(If necessary, microwave for 15 to 45 seconds more, stirring after every 15 seconds or until melted.) Or place the peanut butter pieces in a small saucepan. Cook and stir over low heat until the pieces are melted. Pour the melted peanut butter pieces over the noodle mixture and stir until all of the mixture is coated. Spread mixture into prepared pan, pressing evenly. Cool about 30 minutes or until mixture is set. Use foil to lift mixture from pan onto a cutting board. Remove foil.

Put the white baking chocolate in a small microwave-safe bowl. Microwave, uncovered, on 100 percent power (high) for 45 seconds. Stir until smooth. (If necessary, microwave for 15 to 45 seconds more, stirring after every 15 seconds until melted. Or melt white baking chocolate in a saucepan as before.) Lightly spread the fronts, tops, and sides of tombstones with melted white chocolate. Let stand about 15 minutes or until set. Decorate with icing. Makes 6 to 8 snacks

4. Note: If desired, use 1 3/4 cups noodles from a 5- to 6-ounce can or package for the tombstones and use remaining noodles to make "grass". Place noodles in a large plastic or paper bag; add several drops green food coloring. Close bag and shake to color the noodles. For darker or more even color, add more food coloring and shake again.

If tombstones won't stand,prop them up with large gumdrops or other candy.
