1In a large mixing bowl, stir together the mashed potatoes and butter. Make sure ahead of time they have come to room t
2Stir in the vanilla.
3Add the powdered sugar and slowly mix all together. It will eventually come together like a moist dough. Place in the refrigerator for about an hour to harden.
4Divide the mixture into 4 and shape into egg shapes. Place on waxed paper on a cookie sheet and return to the refrigerator for3 hours until firm.
5Once the eggs are firm, melt the chocolate chips in the microwave 30 seconds at a time, stirring in between, until smooth.
6Now you will need to cover the eggs in the chocolate. Line another cookie sheet with waxed paper. The best way to cover the eggs is to use a pastry brush/basting brush. Place the egg upside down in your palm and brush the chocolate on the bottom of the egg. Place the egg onto the waxed paper chocolate side down. Cover the top of the egg, making sure you cover all of the egg. You can try to make a fancy pattern with the brush if you want! Cover all 4 eggs and return to the refrigerator to set.
7To serve, it is best to let the egg come to room temperature so that the chocolate shell does not crack when you cut it.
