You are what you eat...

Ingredients:

1 cup butter, softened
1-1/2 cups sugar
2 eggs
1 cup (8 ounces) sour cream
1 teaspoon vanilla extract
3 cups all-purpose flour
1 teaspoon baking powder
1/2 teaspoon salt

FROSTING/DECORATING:
4 cups confectioners' sugar
1/2 cup butter, melted
6 tablespoons milk
2 teaspoons vanilla extract
3 to 4 drops red food coloring
Pink sugar wafer cookies
36 large marshmallows, halved
Butterscotch chips and miniature semisweet chocolate chips

Directions:
In a large bowl, cream butter and sugar until light and fluffy. Beat in the eggs, sour cream and vanilla. Combine dry ingredients; gradually add to creamed mixture and mix well.
Drop by tablespoonfuls onto ungreased baking sheets. Bake at 375° for 10-12 minutes or until edges are lightly browned. Remove from pans to wire racks to cool completely.
For frosting, in a large bowl, combine the confectioners' sugar, butter, milk, vanilla and food coloring. Frost cookies.
Cut sugar wafers into triangles; place two on each cookie for ears. With a toothpick, poke two holes in each marshmallow half for nostrils; press butterscotch chips into holes. Place noses on cookies; add chocolate chip eyes. Yield: 6 dozen.

My Ideas:

For the frosting, I would just add a bit of red food coloring to your favorite premade frosting.

To make things easier, you could use premade cookie dough as well!
