beet cookies

beets actually make me want to vom,
but i don't want to die young from eating 
too much red food coloring... 
so i used a bit of puréed beets to make
pink heart-shaped cookies for valentine's day!
the flavor is slightly present, and as someone who hates beets,
i found these cookies really quite enjoyable.
so go ahead and say
i love you
and not
i love you and i wanna kill you with red 40.

1 stick of butter, softened 
1 1/4 cups sugar
1 egg
1 teaspoon vanilla
1/4 cup puréed steamed beets*
1 1/4 cups white flour
1 cup whole wheat flour
1/4 teaspoon salt
1/2 teaspoon baking soda
powdered sugar for dusting
for the icing:
1 stick of butter, softened
1 1/2 cups powdered sugar
1 teaspoon vanilla
