Why You’ll Love This Recipe

Frosted Christmas Brownies are a holiday dream made simple. You start with a boxed brownie mix, so there’s no fussing with complicated steps.

The best part is the decorating. Each triangle slice can become a Christmas tree with green frosting and sprinkles, or a Santa hat with red and white frosting.

They’re colorful, playful, and instantly bring cheer to any dessert table. Because the base is brownies, they’re always moist, chocolatey, and crowd-pleasing.

This recipe also gives you flexibility. Use two boxes of mix for thick, indulgent brownies or one box for a lighter batch. Either way, frosted Christmas brownies will stand out on a holiday platter and become the sweet treat everyone reaches for first.

Ingredients You’ll Need

  • 2 boxes of brownie mix (or 1 box if you prefer thinner brownies)
  • Spray oil for greasing the pan
  • White frosting
  • Red food coloring
  • Green food coloring
  • White pearl sprinkles
  • Edible gold stars

Two boxes of brownie mix make the brownies extra thick and rich, though you’ll need to bake them a little longer. If you want the classic texture, stick with one box. For frosting, white works as your base, and then you can mix in red or green coloring. Decorations like pearl sprinkles and edible stars add sparkle, but feel free to adjust based on what you have.

Step-by-Step Instructions

Step 1 – Prepare and Bake the Brownies

Preheat your oven according to the directions on the brownie mix box. Spray a 9-inch springform pan with oil to keep the brownies from sticking.

Mix the brownie batter following the package instructions. If you’re using two boxes, combine them into one big batch.

Pour the batter into the pan and smooth the top. Bake as directed, checking with a toothpick. When it comes out mostly clean with a few moist crumbs, they’re ready.

Set the brownies aside to cool completely before moving on.

Step 2 – Cut into Festive Shapes

Once the brownies are cooled, carefully release them from the springform pan. Use a sharp knife to cut the brownie into 8 triangle slices. Triangles give you the perfect base for either a Christmas tree or a Santa hat. Work slowly to keep the edges neat.

Step 3 – Make the Frosting Colors

Scoop white frosting into three bowls. Leave one plain white. In the second bowl, stir in a few drops of red food coloring. In the third, add green coloring until you reach the shade you like. Transfer each frosting color into its own piping bag with a decorative tip.

Step 4 – Decorate Your Brownies

For frosted Christmas brownies shaped like trees, pipe green frosting in a zigzag pattern across the triangle. Sprinkle on white pearls as ornaments and top with a gold star. For Santa hats, cover the triangle in red frosting, then pipe a fluffy line of white across the bottom edge and add a white dot at the tip. You can also get creative with candy canes, gumdrops, or edible glitter if you’d like. Once decorated, they’re ready to serve.

Recipe Notes & Tips

Using two boxes of brownie mix will give you tall, bakery-style brownies. Just remember to extend the bake time a little.

If you prefer thinner slices that bake faster, one box is enough. Always let the brownies cool before cutting or frosting, otherwise they’ll crumble or melt the icing.

Adjust frosting colors to your preference. A drop or two of gel coloring goes a long way for bold shades.

Leftover brownies can be stored in an airtight container at room temperature for a couple of days. If you’d like them to last longer, refrigerate them, though the frosting will firm up.

You can also freeze undecorated brownies and thaw them later for a decorating activity. These brownies are best enjoyed fresh, but they’re forgiving enough to prep ahead for a holiday party.

Serving Ideas

Frosted Christmas brownies look amazing on a holiday dessert table surrounded by cookies and candies. They’re also perfect for kids’ decorating parties since everyone can design their own. Try arranging the triangle brownies in a circle to mimic a Christmas wreath for a fun presentation. Pair them with creamy scalloped potatoes perfect for Christmas dinner for a complete festive spread. You can also tuck them onto a holiday platter next to festive chocolate bites for your holiday dessert table and hot cocoa bombs as a fun Christmas treat.
