Prepare chocolate donuts
Preheat the oven to 400° F.
With a hand mixer or whisk, mix the butter, egg, C&H® Light Brown Sugar, C&H® Granulated Sugar, cocoa powder, and vanilla just until combined. Add in the flour, baking soda, and salt. Turn the mixer on slow and slowly drizzle in the buttermilk while mixing in the dry ingredients.
Place the batter in a piping bag or large freezer bag and cut a dime-sized hole for the opening.
Spray two mini donut pans with cooking spray and pip in the batter until 3/4ths full. Place in the oven for 9-11 minutes. Let cool in the pans for 5 minutes before turning out onto a cooling rack.
Prepare peppermint icing
Beat the cream cheese, butter, and C&H® Powdered Sugar together until combined. Add in the peppermint extract and cream and beat until light and fluffy, about 30 seconds.
Spoon over the cooled donuts and sprinkle with peppermint candy bits.
