Preheat the oven to 350 degrees. Spray a mini muffin tin with cooking spray and set aside.

In a large bowl mix together the butter, sugar, brown sugar, and vanilla bean paste. Mix well.

Add in the eggs, stirring until well combined.

In a medium mixing bowl combine the flour, baking soda, and salt.

Stir the dry ingredients into the wet ingredients and mix until a dough forms.

Grab a Cadbury egg and wrap a tablespoon of dough around it so it is covered completely. Placed the cookie on one side of the muffin tin. Repeat with remaining Cadbury eggs and then Reese eggs.

Bake for 9-10 minutes or until golden brown. Remove the pan from the oven and allow to cool for at least 10 minutes in the pan. Gently use your fingertips and twist the cookies out of the pan. Place the cookies on a wire rack to completely cool.

Meanwhile, place the butter in the bowl of a mixer and beat on medium speed. Slowly add in the powdered sugar a half a cup at a time or until desired consistency is reached. Add in the vanilla, milk, and food coloring and mix for an additional minute.

Pipe the icing onto cooled cookies. Place jelly beans or sprinkles on top of the frosting before it starts to harden.
