Cute as a Button Cookies

We're going crazy today! I'm trying to make up for not posting for awhile. These are a great "B" snack or would be oh-so-cute for a baby shower. Thanks to chasingtwilight for this great recipe!!

Cute-as-a-Button Cookies
2 cups sifted all-purpose flour, plus a little more for work surface
1/4 teaspoon salt
1/2 teaspoon baking powder
1/2 cup (1 stick) unsalted butter, softened
1 cup granulated sugar
1 large cage-free egg
1 teaspoon pure vanilla extract
Food coloring
Sanding sugar for sprinkling

Whisk together flour, salt, and baking powder in a large bowl and then set it aside.
Mix the butter and granulated sugar into a seperate bowl and mix that (on medium if you have an electric mixer) until the it’s pale and fluffy.
Add an egg and vanilla. By this time I’m sure you’re arm’s getting tired, but if you have an electric mixer, reduce the speed to low.
Now add your original flour mixture; and mix them together until no visible difference remains.
Divide the dough into thirds, and knead one color of food coloring into the first piece and then your second food coloring into another.
Shape all three pieces into disks. Wrap the disks in plastic wrap and refrigerate until firm. (About an hour)
Preheat your oven to 325!
Remove one disk from refrigerator and let it stand at room temperature until slightly soft, which takes about 5 to 10 minutes.
Roll out dough on a piece of lightly floured parchment to a 1/8-inch thickness, dusting with flour as needed.
Cut out circles with a 1 3/4 inch round cutter, then lightly press with a 1 1/2 inch round cutter.
Make your button holes with a skewer.
Reroll scraps, and cut. (If dough becomes too soft because you keep messing up, refrigerate it for 10 minutes and problem solved.)
Repeat with remaining dough. Space 1 1/2 inches apart on baking sheets lined with parchment paper and sprinkle them with the sanding sugar.
Bake 16 to 18 minutes, then let them cool completely. Your cookies can be stored in airtight containers at room temperature for up to one week.
NOTES: I'd use a round glass/cup to cut the cookies out and a smaller glass to make the button "edges".
