This chocolate buttercream frosting makes every cake or cupcake feel like a special occasion treat. The texture is unbelievably fluffy thanks to a perfect whipping technique and that rich cocoa flavor instantly satisfies any sweet tooth. You can have this ready in just minutes with everyday ingredients you probably already have in your kitchen.
I have whipped up batches of this frosting in a pinch for last minute birthdays and random weeknight treats. Somehow the simplest recipes always get the most rave reviews in my family.
Ingredients
- Unsalted butter: use high quality butter for the best creamy base and total flavor control
- Unsweetened cocoa powder: sift before using for smoothness choose a reputable brand
- Powdered sugar: this is essential for a velvety light consistency check for lumps or sift if needed
- Evaporated milk: brings extra creaminess look for cans with no added sugar and use as needed for consistency
- Vanilla extract: rounds out the flavor pure vanilla is worth the splurge
- Salt: brightens and balances the sweet and chocolate notes sea salt works beautifully
Step-by-Step Instructions
- Cream the Base:
- In a large bowl beat together the unsalted butter cocoa powder vanilla and salt using a hand mixer or stand mixer. Keep mixing until the mixture is fully smooth and looks uniform. Let the butter soften at room temperature before starting for best results.
- Incorporate the Sugar:
- Gradually add powdered sugar to the butter mixture. Mix on a low speed at first to prevent sugar clouds. Once all the powdered sugar is combined increase the speed. Scrape the sides of the bowl frequently to ensure everything is blended.
- Adjust Consistency:
- Add evaporated milk one tablespoon at a time. Beat until the frosting is very fluffy and easy to spread or pipe. The final texture should hold peaks but still be soft enough to spread easily. If you prefer a stiffer frosting use less milk.
- Taste and Use:
- Give the frosting a quick taste and adjust with a pinch more salt if needed. Use a spatula or piping bag to decorate your cake cupcakes or cookies. Work quickly if desired texture is soft and fluffy.

The unsweetened cocoa powder is always my favorite part. I remember once letting my kids help sift it and we wound up with cocoa everywhere giggles included. Now they always volunteer to help with that step.
Storage Tips
Once prepared keep extra frosting in an airtight container in the refrigerator for up to four days. Bring it out about an hour before you need it to let it soften to a spreadable consistency. Give it a good stir to fluff it up before using especially if it has been chilled.
Ingredient Substitutions
If you do not have evaporated milk you can use whole milk instead but you must refrigerate the frosted baked goods. Avoid swapping powdered sugar with granulated sugar since it dramatically changes the texture. If you like a richer taste try adding a tablespoon of espresso powder to enhance chocolate flavor.
Serving Suggestions
Spread generously on classic chocolate cake yellow cupcakes or brownies for bakery style results at home. For a twist make sandwich cookies by pairing it with peanut butter cookies or use it as a filling for chocolate sandwich cakes. A swirl of this frosting will even elevate store bought treats to homemade status.
