Sift together the flour and powdered sugar twice, set aside.
In a stand mixer bowl, add the egg whites and mix until frothy. Add the cream of tartar and mix together on medium speed. Slowly add in the granulated sugar a little at a time. Whip egg whites on medium-high speed until stiff peaks form. Stir in vanilla and food coloring. (Add as much black food coloring as needed to get the color you want.)
Sift in flour mixture and with a spatula, fold in the dry mixture into the egg whites. This will take a while, be patient. Keep folding until you can form ribbons (at least 50 folds). Then, place a small dollop on a plate, if the ridges flatten themselves out within 10 seconds you are ready.
On two parchment lined cookie sheets, pipe out mixture into 1 1/2 inch circles one inch apart. Late sit on the counter top for 15-30 minutes, until you touch the top of the cookie and it doesn't stick to your finger. While you are waiting, preheat the oven to 300 degrees.
Bake for 18-20 minutes one tray at a time. They should not be browned at all. To prevent browning, place another sheet tray on the rack above the cookies. Let cool on the tray for 10 minutes, take them off and cool completely on a wire rack.
Place the cream cheese and butter in a large bowl. Cream together until mixed with a hand mixer on medium speed. Slowly add in the powdered sugar a little at a time until combined. Slowly add in the milk and vanilla, mix for 3 minutes on medium-high speed until fluffy. Mix in the cookie crumbs.
Take one macaron and place it downside up. Pipe a little bit of the frosting.
Take the chocolate sandwich cookies and separate the two sides. Scrape off the cream. Snap cookies in half and use each half as one wing. (See photos for exact placement.)
Pipe a little more frosting on top and top off with another macaron.
To place the eyes, just add a tiny bit of frosting on the back of each eyeball. Place them where desired.
