Preheat oven to 350?F. Line cookie sheet with parchment paper.

In mixing bowl, combine flour, baking soda, salt and oats; set aside.

In second bowl, cream butter and both sugars until fluffy. Add eggs one at a time, beating well after each addition. Slowly add the flour-oat mixture, thoroughly mixing it into batter. Divide batter in half, wrap in plastic, and chill 1 hour.

To make each cookie, scoop off generous tablespoon of dough. Flatten slightly, and place an unwrapped SNICKERS® Brand Mini for Easter in center of each piece of dough, wrapping dough completely around. Shape cookie in palm of your hand, molding to resemble an oval. Transfer cookies to cookie sheet.

Bake until golden brown (about 15 to 17 minutes). Remove from oven, transfer to wire rack and let cool completely.

Divide frosting into quarters, and tint each a pastel color. Spoon frostings into resealable plastic bags. Cut 1 tiny, pinprick snip from corner of each bag for thin drizzle. Heat each bag 5 seconds in microwave until frosting softens slightly. Then, drizzle frosting on top of cookies in a decorative pattern.
