Learn how to make the BEST EVER Brownie Frosting! It’s a cooked chocolate fudge frosting that coats the brownies like a rich ganache. It’s irresistible and takes an ordinary brownie to a whole new fudgy chocolate level.
The BEST Brownie Frosting Ever!
These easy double chocolate fudge brownies were my undoing the first time I made them. I could not resist them at all! The actual brownie part is fantastic – rich and fudgy – but it’s the brownie icing that’s really the star. It’s has a texture like ganache and is super-rich like fudge. So, the best name for it is double fudge frosting.
This chocolate frosting for brownies is the best I’ve ever had. It’s a cooked chocolate frosting with heavy whipping cream, butter, and sugar. You pour it on the brownies and let it cool. It’s like ganache but better.
You can use it to top any brownie recipe, but I love it with my brownies made with my homemade brownie mix. But you know what? It’s a great addition if you want to make a box mix. It will take them to a whole new level.
Ingredients Needed
- Brownies: For this recipe, you can use a store-bought brownie mix. Just follow the instructions on the box! Or, make homemade double chocolate brownies with my from-scratch brownie mix instead. Make and bake the brownies first and then let them completely cool before icing them.
- Heavy whipping cream: There is no substitute for this!!!
- Sour cream: Also, no substitute for this – it makes a nice creamy frosting.
- Instant coffee granules: This is optional! Your frosting won’t taste like mocha or coffee, but the bit of coffee accentuates the chocolate flavor, making it much deeper and more intense.
- Granulated Sugar: Weird, I know! But it’s a cooked frosting!
- Cocoa: Use any unsweetened cocoa powder – you can use regular, dark or dutch process. Learn all about cocoa!
How to Make Brownie Frosting
- Whisk the cream, sour cream, instant coffee, and vanilla in a bowl or large measuring cup.
- Place the butter in a saucepan and melt over low heat. Once it’s melted, whisk in the sugar.
- Then add the cocoa powder, and salt.
- Whisk them until they’re thick and combined.
- Slowly add the wet ingredients while whisking, and then cook the frosting for two to three minutes over low heat. Don’t let it boil.
- As it cooks, it will slightly thicken – once that happens, take the pan off the heat.
- Pour the frosting over the brownies and use a spatula to smooth it. Allow the frosting to cool completely. Chill the frosted brownies in the refrigerator if you want the frosting to harden.
Expert Brownie Icing Tips
- The instant coffee is optional, but it gives the frosting a rich chocolate flavor, so I definitely recommend using it.
- Don’t boil the frosting when you cook it. Instead, cook it on low for the recommended time. This will ensure you get a rich, fudgy texture.
- Wait to ice the brownies until they are completely cooled.
- Store frosted brownies loosely covered at room temperature. They will keep for three days.
- Or, store them in the refrigerator if you prefer hardened icing.

So sorry to hear about your new neighbors! What an awful ordeal. But these brownies look fantastic! I so adore the heart shaped ones with sprinkles. Love!
Why can’t we be neighbors?! I’d be pissed if my neighbor had floodlights that were coming into my bedroom at all hours of the day! I love a pitch dark bedroom at night. Ugh.ย But on the bright side, these brownies are perfect!! I love the football and heart ones! There’s really nothing better than a good fudgy brownie. Pinned!!
The football ones are adorable! They would make the perfect addition to any Super Bowl party. Frosted brownies are a major weakness, as is whipped cream so I’m guessing me and these brownies will become fast friends ๐
