To make the icing, combine the melted butter, cream, food coloring (or charcoal powder) and powdered sugar. Mix until all of the sugar has dissolved. (If the icing is too thick, add a bit more cream, if it is too thin, add a bit more powdered sugar.)
Once the donuts have cooled completely, dip the top of the donut into the freshly made icing. Place dipped donut onto a plate or tray.
Finish dipping the remainder of the donuts then place candy eyeballs onto each of the donuts, you can do as few as 2 or as many as 8 or more on each!
Place the tray of donuts into the fridge for 15-30 minutes, or until the icing has hardened a bit.
While the donuts are in the fridge, melt the chocolate chips in a small microwave safe container.
Dip each one of the pretzel sticks about 80% the way into the chocolate, spin the sticks against the side of the container to remove excess chocolate, as you only need a thin layer. Then dip the chocolate covered pretzel into the chocolate sprinkles. Set the pretzel onto a parchment lined tray. Repeat this for all of the pretzel sticks.
Once all of the pretzel legs have been made, place the tray into the fridge to let the chocolate harden.
When the donuts and the legs have hardened, and you are ready to serve, remove the donuts from the fridge and gently stick 6-8 of the legs into each donut.
Serve, and enjoy your spooky treat! Enjoy every bite!
