Make the Donuts - Preheat oven to 350 degrees. Spray one 6-count donut pan with non-stick cooking spray, Set aside.

In the bowl of your mixer combine the sour cream, eggs, sugar, oil, lime zest and cherry extract.

Fold in flour, baking powder, baking soda, and salt, mix until incorporated. Add in food coloring until you achieve your desired color.

Fill donut pan, and bake for about 13 to 15 minutes. They will be springy to the touch.

Prepare Lime Glaze In a small bowl, add powdered sugar and slowly drizzle in the lime juice while whisking until smooth and combined. You may not need ALL of the juice. Quit adding when you get your desired consistency. Don't worry, if it gets too thin, add more sugar until you're happy with it.

When donuts are hot, remove them from the pan, when you are able to touch them, dunk the top in the glaze and let them dry/cool on a wire rack. (I like to double dunk mine!!) Top with fresh lime zest.

Spray and fill pan up one more time, repeating all of the steps. Makes 10 donuts. (if glaze begins to harden in between batches, simply pop it in the microwave for a few seconds and give it a stir)

Best eaten when fresh. Store in an airtight container up to 4 days.
