Beat together powdered sugar, peanut butter, and butter together. At this point the dough will be crumbly. Add two tablespoons of milk and continue to beat together until the dough softens. If the dough still seems crumbly that is ok.
On a floured surface, roll the dough out to desired thickness. About 1/2 thickness. You can use egg cookie cutters or with a knife, shape the dough to look like eggs.
Place eggs on a cookie sheet and put in the freezer for an hour.
When you are ready to dip them, add the chocolate and 1 Tbsp shortening in a microwave and melt 30 seconds at a time. Stirring it after every 30 seconds and being careful not to cook the chocolate to burn.
Dip each egg in chocolate. I used a spoon to help cover in the chocolate. Place them on wax paper to set.
If using colored candy melts, melt each color in the microwave stirring 30 seconds at a time. Scoop the chocolate into a small zip lock bag. Snip the corner and drizzle onto each egg.
If more chocolate is needed, melt the second bag with the shortening. Enjoy!
