In a large microwave safe bowl heat your almond bark or white chocolate for 1 minute. Stir and heat for 20 second intervals, stirring after each until completely melted and smooth. Add in your red food coloring and stir until you get your desired color.
Hold the cookie near the top and dip 2/3rds of the way into the chocolate. Gently shake off the excess and place on a lined baking sheet.
Add the eyes to the edge of the chocolate to "glue" them into place, and add your sprinkles.
Let the cookies set up for 1-2 hours until the chocolate is completely solid.
Notes
You can use red or pink candy melts in place of coloring your own white chocolate
