1. Color fondant desired brown color (we used a combination of yellow and brown). Roll fondant into 3/4" balls.
Using a wooden skewer or the end of a candy thermometer make a hole that goes all the way through the center of the ball.
With a forefinger and a thumb on each side of the ball (covering the holes), lightly press down to flatten ball. Flatten sides too if necessary. It should look like a naked doughnut at this point.
Dip top part of the doughnut into icing glaze.
Use skewer or thermometer again to remove icing from hole.
Dip doughnut into sprinkles.
Use skewer or thermometer to remove sprinkles from the hole. Set aside and let dry over night.
Once they are dry, you can add them to the border of your cake. And if you want to make a doughnut topper, repeat the same process using a larger piece of fondant.
