I saw these on www.stephanieskitchen.com and loved them. I made her version and didn't really like the peanut butter filling. It had brown sugar in it which made it seem like I was eating sand. So, I found my favorite peanut butter filling recipe from my Mrs. Fields cookbook and now we have the perfect pretzel bites.
Peanut Butter Filling:
1 1/2 cups creamy peanut butter
1 stick (1/2 cup) salted butter, softened
3 cups confectioners' sugar
2 teaspoons vanilla extract
Blend peanut butter and butter together until smooth. Slowly beat in confectioners' sugar and then add the vanilla. Beat until smooth. Roll into one inch balls and squish between two square pretzels. Dip into melted chocolate. I used almond bark this time, but I prefer to work with Wilton's candy melts.
I have also used this filling to spread over cooled brownies and then spread melted chocolate on top of it. You can also take a small chocolate chip cookie (like Chips Ahoy or you could use the mini vanilla wafers) and press a ball of peanut butter filling on top then dip in chocolate. Kind of like a bonbon type of treat. Really, there are so many possibilities with this filling. I'd love to hear your ideas!
