I make a recipe similar to TiffanyK for Peanutbutter balls only simpler:
1 lb confectionary sugar
2 sticks butter
1 18 oz jar peanutbutter
Melt peanutbutter and butter in microwave, blend together in mixer. Add confectionary sugar. Blend until smooth.
Chill for about 1 hour then form into balls - you can make small balls of 1/2 - 3/4 inch or larger balls of 1 - 1 1/4 inches or so. Set Aside on cookie sheet covered in waxed paper - if more than one tray keep additional trays chilled until ready for dipping.
Melt 1 pkg of semi sweet chocolate chips or 12 oz of Dove Dark Chocolate Squares in a double boiler over low heat. Using a toothpick poked into one end of the peanut butter ball halfway into the chocolate. Set back on wax paper to cool and harden. Store in cool dry place. May be frozen.
In extra chocolate pour a small amount of raisins, dried cranberries and chopped nut of your choice. Stir. Keep adding by small amounts until thick mixture forms but you want to leave loose chocolate so that the fruit and nuts blend together. Drop by spoonful on waxed paper. Cool.
I also dip dried fruit. You can use either milk or dark chocolate. Each piece halfway. Apricots, apples, banana chips, and most amazing sweetened dried orange rind - this I dip 3/4 of the way. To make it look extra special after dipping melt a small amount of a different color chocolate (if dipped in dark use white or milk, if dipped in milk use dark or white) drizzle over the other chocolate.
You can also dip potato chips - sounds weird but tastes amazing - but use a thick ridged chip so the weight of the chocolate doesn't break the chip. Ruffles brand work best.
