Ingredients

For the Brownies

1 cup unsalted butter, melted
1 ¼ cups granulated sugar
1 cup brown sugar
4 large eggs
2 teaspoons vanilla extract
1 cup unsweetened cocoa powder
1 cup all-purpose flour
½ teaspoon salt
1 cup semi-sweet chocolate chips (optional but recommended)

For the Colorful Christmas Tree Frosting

1 cup unsalted butter, softened
3 ½ cups powdered sugar
1 teaspoon vanilla extract
2–3 tablespoons milk or cream
Green gel food coloring
Red, gold, or multicolored sprinkles
Mini M&M’s or sugar pearls (optional)
Small star-shaped candies for tree toppers

Additional Items

Lollipop sticks or pretzel rods (optional “tree trunks”)
Wax paper or parchment paper

Instructions

1. Prepare the Brownies

Preheat your oven to 350°F (175°C). Line a 9×13-inch baking pan with parchment paper, leaving two sides hanging for easy removal.
Whisk melted butter, granulated sugar, and brown sugar until smooth.
Add the eggs one by one, mixing well after each addition.
Stir in vanilla extract.
In a separate bowl, sift together cocoa powder, flour, and salt.
Fold the dry mixture into the wet mixture until just combined.
Add chocolate chips if using.
Spread the batter evenly in the prepared pan.
Bake for 25–28 minutes, or until the center is set.
Allow brownies to cool completely before cutting.

2. Cut into Christmas Tree Shapes

Once cooled, lift the brownies out of the pan using parchment edges.
Cut into long strips, then slice each strip into triangles.
If desired, insert a pretzel rod or lollipop stick into the base of each triangle to act as a tree trunk.
Place brownie trees on a lined surface for decorating.

3. Make the Frosting

Beat softened butter until creamy.
Gradually add powdered sugar.
Mix in vanilla and 1 tablespoon of milk at a time until smooth and pipeable.
Tint green using gel food coloring.
Transfer frosting to a piping bag fitted with a star or round tip.

4. Decorate Your Christmas Trees

Pipe zig-zag swirls to resemble tree garland.
Add sprinkles or candies as ornaments.
Place one small candy star at the top of each brownie tree.
Allow frosting to set before serving.

Expert Tips for Perfect Christmas Brownies

Use parchment paper so you can remove the brownies without breakage.
Chill before slicing to get perfectly sharp triangle edges.
Gel food coloring gives brighter results without thinning the frosting.
Pipe frosting slowly to create elegant, evenly spaced garlands.
Use a thicker frosting consistency so the piped lines stay crisp and defined.
Experiment with piping tips for unique tree patterns and textures.

Variations

1. Peppermint Christmas Tree Brownies

Add crushed candy canes to the frosting or sprinkle peppermint pieces on top.

2. Red Velvet Tree Brownies

Tint the brownie batter with red food coloring for a festive twist.

3. Gluten-Free Christmas Tree Brownies

Use a high-quality gluten-free 1:1 baking flour.

4. White Chocolate Drizzle Trees

Instead of frosting, drizzle white chocolate for a minimal, elegant look.

5. Grinch Green Trees

Use neon green frosting with red heart-shaped sprinkles.

Serving Suggestions

Serve with hot cocoa, milk, or peppermint lattes.
Wrap individual brownie trees in clear bags tied with festive ribbons.
Add them to a holiday dessert board for a visually stunning spread.
Use them as edible place cards by piping names onto the plates.
