If National Lampoonโs Christmas Vacation taught us anything, itโs that the holidays are meant to be over-the-topโand this hot chocolate buttercream frosting totally delivers.
Made with real hot cocoa mix, itโs just the right amount of sweet with a subtle chocolate flavor. A nostalgic holiday treat that pairs perfectly with laughter, lights, and maybe a squirrel in the Christmas tree.
Spread it thick on cupcakes, brownies, or cookies, and watch it disappear faster than Clarkโs Christmas bonus.
Pair this frosting with with my hot chocolate cupcakes, easy chocolate cupcakes, and red velvet cupcakes.

How to Make Hot Chocolate Buttercream Frosting
Step 1: Whip the butter for 5 minutes until light, pale, and creamy.
Step 2: Add in the powdered sugar and mix on low speed until combined.
Step 3: Add in the hot chocolate mix, heavy cream, vanilla extract, and salt and mix until combined and smooth.
Step 4: Whip the frosting for 3 to 5 minutes on medium speed until smooth and creamy. Then, mix on low speed for several minutes to remove the air bubbles.

Courtney’s Expert Buttercream Tips
- Use room temperature butter and whip the butter for several minutes to achieve a light and fluffy frosting texture.
- Be sure to mix the frosting until it is silky smooth. Because we are adding hot cocoa mix, the granules take a little bit of time to dissolve. The length of time can depend on the brand of hot cocoa mix you are using, but usually 5 minutes does the trick.
- To make super smooth buttercream, heat 1 cup of the frosting in the microwave for about 15 seconds to melt it slightly. Then, add the melted buttercream back to the mixing bowl and mix on low speed for several minutes.
