Let me start by saying that I don't like these at all. The smell alone makes me gag. But I also can't stand Reese's Peanut Butter Cups, so I am a crazy person. I do have it on good authority that if you happen to actually enjoy eating peanut butter and chocolate mixed into a single food item--oh, the horror!--these are pretty tasty.
3/4 cup peanut butter
1/2 cup butter
1/4 teaspoon vanilla
3 cups powdered sugar
2+ cups semi-sweet chocolate chips
Cream peanut butter, butter, and vanilla. Add powdered sugar and mix thoroughly. The mixture will look a bit dry.
Roll mixture into one-inch balls and place on a cookie sheet lined with waxed paper. Chill balls in freezer until firm, about 30 minutes.
Melt the chocolate chips in a double boiler over simmering water until smooth, stirring frequently.
Stick a toothpick in a ball and, using the toothpick as a handle, dip the ball in the melted chocolate. Coat the ball well, leaving a small area of the peanut butter mixture showing at the top. Put the ball back on the sheet and carefully remove the toothpick. Repeat.
Let the chocolate set in the fridge. Refrigerate until serving.
