How to Make Chocolate Buttercream Icing Recipe

Make the Chocolate Mixture – Whisk the cocoa powder, espresso powder, salt, hot water and vanilla extract together into a thick chocolate paste.
Whip Butter and Confectioner’s Sugar – Use and electric mixer fitted with the whisk attachment to beat the butter with the powdered sugar until smooth.
Combine – Add the chocolate paste mixture along with the melted chocolate and corn syrup. Beat on medium speed until smooth. The frosting will be on the thinner side (compared to usual buttercream frostings) but the frosting will firm and set as it stands.
Use – Once the frosting is done, slather on vanilla cake, chocolate cake, strawberry cake or cupcakes, brownies, cookies or sheet cakes.

Recipe Variations, Tips and Substitutions

Cocoa Powder – You could use dark cocoa powder like Hershey’s dark or Dutch-processed cocoa powder for an even deeper chocolate flavor.
Chocolate – You could use bittersweet chocolate in place of semi-sweet chocolate.
Flavorings – You could add a dash of almond extract, rum extract or raspberry extract to change the flavor profile.
Sugar – You can add 1/2 cup additional powdered sugar (also called icing sugar) until it reaches the right consistency.
Corn Syrup – You can use heavy cream in place of corn syrup. Add one tablespoon at a time until your desired consistency is reached.
Allow Time for the Frosting to Set – This buttercream will firm once chilled. I recommend storing any cakes topped with this frosting chilled in the refrigerator. Allow time to come to room temperature to soften for serving. When serving immediately, let the cake stand at room temperature for about 10-15 minutes to allow the frosting to set properly before slicing.

Storage and Leftovers

Make-Ahead Tip – You can make this chocolate buttercream frosting up to 5 days in advance and store it in an airtight container chilled in the refrigerator. Bring to room temperature and whip with a hand mixer or a whisk prior to using.
Leftovers – It’s ideal to make this frosting and use it immediately while it’s soft. You can store frosted cakes chilled in the fridge for up to 5 days, generally speaking.
Freezer – Place frosting into a freezer-safe airtight container and store frozen for up to 3 months. To use, thaw in the fridge overnight then allow 20-30 minutes on the counter to come to room temperature. Whip with a hand mixer or a whisk to fluff prior to using.
