Since your cupcakes will need time to cool completely before frosting, I recommend starting with this step.
Prepare the chocolate cupcakes
Then transfer them to a cooling rack and allow them to cool completely.
Bake the cupcakes
Melt the chocolate mix in the green food coloring. Transfer the melted chocolate to a piping bag or ziplock bag with a small hole snipped in one corner.
Make the Christmas tree toppers
Pipe the chocolate over the Pocky sticks in the shape of a tree. Add sprinkles and allow chocolate to solidify.
Tree toppers cont.
Make the vanilla buttercream frosting
Once the cupcakes have cooled completely, frost and sprinkle with coconut shavings.
Gently push one Christmas tree topper into the top of each cupcake.
