Preheat the oven to 350 degrees Fahrenheit. Line baking sheet with parchment paper and set aside.
Add the sugar and softened vegan butter to the mixing bowl. Mix on high until fluffy.
Add the flour, baking soda, peppermint, and vanilla. Mix until dough forms.
Form dough into 1/2 inch balls and arrange on cookie sheet. Dip a glass in sugar and press cookie flat. (Repeat dipping glass into sugar and flattening cookies.)
Bake for 8-10 minutes or until slightly puffy with edges just light brown.
Allow to cook 5-7 minutes on the baking sheet before transferring to cooling rack. (This allows the cookies to firm up a little more before transferring to a rack.)
When the cookies have cooled completely, melt the chocolate chips in the microwave. Drizzle over cooked and sprinkle with crushed peppermint candy. Transfer to the fridge 10 minutes to set the chocolate.
Store in an airtight container or ziplock bag for up to a week. Freeze well!
