Beat the peanut butter, powdered sugar, and melted butter until well combined. Add the milk and combine. Filling will be crumbly.
Grab a few tablespoons of the peanut butter mixture and roll into the shape of an egg. Place on a cookie sheet and freeze about 15-20 minutes to harden.
While the peanut butter hardens, melt the chocolate with the shortening using your microwave in thirty second intervals.
Grab the peanut butter eggs from the freezer and dip them individually in the chocolate. I like to set them on a cookie sheet covered with parchment paper.
Allow the chocolate to harden. These keep best if they are refrigerated.
