Prepare the cake batter according to the package directions. Line a muffin pan with cupcake liners, divide the batter evenly, and bake as directed. Let the cupcakes cool completely before decorating.

Line a baking sheet with parchment paper and place two pretzel sticks side by side to make the “trunk” of each tree.

Melt the green candy wafers according to package instructions, then transfer to a piping bag or zip-top bag. Pipe the melted candy in a zigzag triangle shape over each pretzel pair, making sure to add extra chocolate where the sticks meet so the trunks stay sturdy.

While the candy is still wet, decorate with mini M&M’s and a star sprinkle. Let them set until firm.

Frost the cooled cupcakes with vanilla frosting, then dip the tops into shredded coconut to look like snowy ground.

Once the pretzel trees are completely set, gently press one into the center of each cupcake.
