This recipe has similar ingredients to the peanut butter pretzel balls recipe I posted a month or so ago, so I decided to try it out since I had the ingredients on hand. Yummers!
1 cup creamy peanut butter
2 Tbsp. softened butter
1/2 cup powdered sugar
3/4 cup brown sugar
Pretzels
1 bag semi-sweet chocolate chips
Combine peanut butter and softened butter with a large fork or in the bowl of a stand mixer. Add the sugars and combine to mix. At this point, the filling will roll into balls without sticking to your hands; if it doesn't, add a little more of each sugar until it does. Use a teaspoon measure to scoop the filling, roll into a ball, and squish between 2 pretzels. When all "sandwiches" have been made, put in freezer for 30 minutes or more to harden.
Pour the chocolate chips into a bowl, and microwave to melt, stirring in 30-second intervals. Add 1 Tbsp. of peanut butter into the chocolate just before completely melted, then microwave slightly more until smooth. Remove pretzels sandwiches from the freezer and dip each half-way into the chocolate. Place on tray to dry, then freeze or refrigerate to set. Store extras in refrigerator.
