To begin, preheat your oven to 350 and line two pans with parchment paper (or spray with non-stick spray).
To a large mixing bowl, add your butter and sugar and cream them together with a mixer for a couple minutes, till creamy. Add your red food color, vanilla and egg and blend again briefly till all ingredients are combined.
To a separate, small mixing bowl, add your flour, cocoa powder, baking soda and salt. Whisk thoroughly till well combined.
Pour your dry ingredients into your wet ingredients and mix them together till you have a smooth cookie dough batter.
*Prepare your bowl of sprinkles (or extra sugar) for rolling the cookies in. Scoop each cookie, roll it around covering it entirely in sprinkles, and place it onto your pan. Repeat. Evenly space your cookies apart, with no more than 12 cookies per pan. Bake for 9-11 minutes, or till the edges of the cookies are set but the center looks a touch underdone.
Remove your cookies from the oven, and gently press a Hershey kiss into the center of each cookie. Let cool entirely then devour!
Stored in an airtight container these cookies taste best within the first 3-4 days.
