Assemble all your ingredients. Cover a cookie sheet with wax paper.
Make sure your cookies are soft and fresh. Stale or crunchy cookies will break.
Use a small round cookie cutter to cut out the center of each cookie (to form the doughnut shape).
Place frostings in separate microwave safe bowls. Heat in the microwave for about 10-20 seconds each.
This is the time to color or flavor your frosting, if desired.
Spoon or spread the frosting on the top of each doughnut cookie. Sprinkle with toppings. You can even do the “doughnut holes” (the cookie circles you cut out). Chill to set. Store loosely covered at room temperature.
