Chocolate Peanut Butter Sweeties

These were sooooo yummy! They're definitly going on my list of goodies for Christmas this year! And they're super easy.
What you need:
1 cup Peanut Butter
1/2 cup Butter(no substitutes)
3 cups powdered sugar
5 dozen mini pretzels
1-1/2 cups milk chocolate chips
1 TBS vegetable oil

What you do:
In a mixing bowl, beat peanut butter and butter until smooth. Beat in powdered sugar until combined. Shape into 1 in. balls (I made mine a little too big. It's best if they're small enough that you can pop the whole thing into your mouth in one bite.); press onto a pretzel. Place on a waxed paper lined baking sheet and refrigerate until peanut butter is firm(I put mine in the freezer for around 20 minutes and that worked fine). In a microwave-safe bowl or heavy saucepan, melt chocolate chips and oil. Dip the peanut butter balls into the melted chocolate and return to baking sheet pretzel side down. Refrigerate for atleast 30 minutes before serving. Store in the refrigerator.
