Method
Bake the brownies
- Heat the oven to 350°F. Grease a 9x13-inch baking pan with nonstick cooking spray, line it with parchment paper with overhanging edges, and grease the parchment.
- Melt the butter and chocolate in a microwave-safe bowl in 30-second increments, stirring between each, until smooth; cool for 5 minutes.
- Whisk the sugar into the chocolate mixture, then whisk in the eggs one at a time and the vanilla.
- Fold in the flour and salt just until no dry streaks remain.
- Spread the batter evenly in the pan.
- Bake for 28-34 minutes, until the edges are set and a toothpick inserted in the center comes out with a few moist crumbs.
- Cool completely in the pan.
- Refrigerate the brownie slab for 30 minutes.
- Lift it out using the parchment and cut 12 trees with a 2 1/2-inch tree-shaped cookie cutter.
Make the icing
- Whisk the confectioners' sugar, 2 tablespoons milk, vanilla, and green food coloring until smooth, adding the remaining milk a teaspoon at a time until the icing is thick enough to pipe.
Decorate
- Spoon the icing into a piping bag or a zip-top bag with a corner snipped off, then pipe a zigzag over each brownie.
- Press a pretzel stick into the base of each tree for a trunk, snapping the sticks to fit if needed.
- Add sprinkles.
- Let the icing set for 20 minutes.
Notes
For clean tree shapes, chill the brownie slab well before cutting. Store in an airtight container in the refrigerator for up to 4 days; freezer-friendly. For a dairy-free variation, use plant-based butter, dairy-free chocolate, and plant milk.
