These Christmas brownies are easy to make with the best from-scratch fudgy brownies and homemade vanilla frosting. Cut the brownies into triangles, then decorate them as Christmas tree brownies or Santa hats for a fun and festive Christmas dessert!
Preheat oven to 350℉ (177℃), line a 9x9” (23 cm) baking dish with parchment paper and lightly grease, set aside.
Melt chocolate and butter together in a microwave safe bowl, or on the stovetop over low heat. Stir until smooth and glossy. Set aside.
In the bowl of a standing mixer, beat eggs for 1 minute or until pale and thick.
Add sugar and beat for an additional 1 minute.
Add melted chocolate/butter mixture and vanilla and stir on low speed until batter is smooth.
Add flour, cocoa powder and salt and mix on low speed until just incorporated and there are no lumps.
Bake in the preheated oven for 25 minutes, or until the edges are set and the center is barley jiggly.
Remove from the oven, put on a wire rack and let cool completely.
Make the Vanilla Buttercream Frosting
Once the brownies are cooled, make the buttercream frosting.
In the bowl of a standing mixer fitted with the paddle attachment, or in a large bowl with a handheld mixer, beat the butter, vanilla and sea salt for 1 minute.
Add 2 cups of the powered sugar and beat until incorporated.
Then, add the milk and the rest of the powdered sugar, beat until smooth and fluffy.
Divide the frosting into three bowls, one small portion (to keep white) and two bowls with equal amounts.
Make one of the larger bowls red by adding the red food coloring, and make one green.
Put into piping bags fitted with a round tip or star tip.
Cut the Christmas Brownies
Start by cutting the brownies in half horizontally to make two rectangles.
On one end of the first rectangle, make adiagonal cut to remove a small right triangle. Then, make another diagonal cutin the opposite direction to create your first full triangle brownie.
Make three more diagonal cuts in alternating directions to cut the rest of the brownies into triangles.
When you reach the other end, you'll have one more small right triangle to trim off.
Repeat the process with the second rectangle.
Decorate the Brownies - Christmas Tree Brownies
To make Christmas tree brownies, place the brownie triangles with the wide side at the bottom.
Pipe green frosting back and forth across each brownie,starting at the bottom and gradually making the lines shorter as you worktoward the top to create the shape of a Christmas tree
Decorate with Christmas sprinkles that look like ornaments. Add a star sprinkle or candy to the top, if desired.
Decorate the Brownies - Santa Hat Brownies
To make Santa hat brownies, pipe red frosting back and forth over the brownie triangle, leaving space at the top and bottom to pipe on a white ball and white trim. Then add sprinkles if you want to.
Harden & Serve
Let the frosting harden before serving the brownies at room temperature.

Notes
Ingredient Notes & SubstitutionsBrowniesI use my favorite homemade brownies for this recipe. You can use a box mix if you prefer.
Chocolate. Use high-quality semisweet or bittersweet chocolate. Chocolate chips, bars or discs all work well because it's being melted.
Salted Butter. Unsalted butter works well too. So does vegan butter.
Granulated sugar. Regular granulated sugar or organic cane sugar both work well.
All-purpose flour. A 1:1 all-purpose gluten-free flour can be used to make gluten-free Christmas brownies.
Cocoa powder. Regular unsweetened cocoa powder is the best choice, but dark cocoa powder can be used for an even richer chocolate flavor.
Food coloring. You'll need red gel food coloring and green gel food coloring to make both designs. I suggest gel food coloring because it creates vibrant colors without thinning the frosting.
You can also use small candy decorations to make ornaments and stars on top of the trees.
How to Store Christmas BrowniesStore decorated Christmas brownies in a single layer in an airtight container at room temperature for up to 3 days or in the refrigerator for up to 1 week.FreezeTo freeze decorated Christmas brownies, put them on a baking sheet in a single layer in the freezer until hardened. Then transfer to an airtight container and store in a single layer for up to 1 month. Thaw overnight in the refrigerator or at room temperature. Absolutely do not microwave - it will melt the frosting.
