Adapted from Cooks Illustrated, this rich and creamy chocolate buttercream tastes like a chocolate bar in frosting form. Unlike most chocolate buttercreams, it’s made with real chocolate in addition to cocoa powder, which makes all the difference in flavor. Not only is the recipe quick and easy but it’s also foolproof – a welcome change from most homemade chocolate buttercreams, which are temperamental. Using a food processor ensures that the buttercream turns out smooth, creamy, and glossy. If you don’t have one, an electric mixer will work too, but you’ll need to sift the cocoa powder before adding it to prevent lumps and allow a little extra time for mixing at every step. The recipe makes about 3 cups, which is enough for 24 cupcakes, one 8 or 9-inch layer cake, or one 9×13 sheet cake.

What You’ll Need To Make Rich Chocolate Buttercream

Step-by-Step Instructions

Place the chocolate in a microwave-safe bowl. Cook in the microwave in 20-second intervals, stirring in between, until about three-quarters of the way melted. Stir, allowing the residual heat in the bowl to melt the remaining chocolate completely. (If necessary, place the chocolate back in microwave for a few seconds.) Set aside to cool.

Servings: 3 cups
Total Time: 15 Minutes

Ingredients

  • 8 ounces semi-sweet or milk chocolate melting wafers (or bars, broken into small pieces) (see note)
  • 2½ sticks (20 tablespoons) unsalted butter, softened but still cool
  • 1¼ cups confectioners' sugar
  • ½ cup unsweetened natural cocoa powder, such as Hershey’s
  • ⅛ teaspoon salt
  • ¾ cup light corn syrup
  • 1 teaspoon vanilla extract

Instructions

  1. Place the chocolate in a microwave-safe bowl and cook in the microwave in 20-second intervals, stirring in between, until it's about three-quarters of the way melted. Stir, allowing the residual heat in the bowl to melt the remaining chocolate completely. (If necessary, place the chocolate back in microwave for a few seconds.) Set aside to cool.
  2. In a food processor, process the butter, confectioners’ sugar, cocoa powder and salt until smooth, about 30 seconds, scraping down the sides of the bowl as needed. Add the corn syrup and vanilla and process until just combined, 5 to 10 seconds. Scrape down the sides of the bowl, then add the lukewarm melted chocolate and pulse until smooth and creamy, 10 to 15 seconds. Do not overmix.
  3. The frosting can be used immediately or held at room temperature for 3 to 4 hours. It may lose its shine as it sits—to bring the shine back, run a metal spoon under hot water, then wipe dry with a towel; stir the frosting with the hot spoon and it should shine right up.
  4. Note: If frosting a vanilla/yellow cake, milk chocolate is recommended for a creamier, smoother chocolate flavor. If frosting a chocolate cake, semi-sweet, milk chocolate, or a combination will work well.

  • Hi! I’m planning to make this to top your yellow layer cake for a family birthday. Do you recommend using milk chocolate for the yellow cake like you do for the Chocolate Lover’s Birthday Cake? Even a couple of the adults aren’t huge chocolate fans, although the “birthday boy” has requested chocolate.

    • Hi Carol, I’d definitely go with the milk chocolate. Hope everyone enjoys!

  • Hi! I really want to try this recipe, it looks great! But, as I only have 70% Cacao Dark Chocolate, can I use that instead of the chocolate used in the recipe? And if I don’t have a food processor/electric mixer, would a blender work too? Thank you so much! I’m going to use this as the buttercream for a marble cake (from your website as well!).

    • Yes, 70% cacao dark chocolate should be fine here. And if you have a very powerful blender like a Vitamix, it may work but I can’t say for sure as I’ve never tried it. Good luck!

  • The cake is fabulous. The icing is a runny mess. I don’t know whether to add more powdered sugar or what. I have never had icing turn out like this.

    • Hi Brenda, I’m sorry you had a problem with the frosting! It’s a bit of a head-scratcher as I have this frosting recipe in two other recipes on the blog (the Chocolate Lover’s Birthday Cake and Chocolate Cupcakes) and haven’t gotten that feedback. Is there any chance at all you may have made a measuring error? Regardless, I’m sorry it was a fail for you!

    • Mine was runny too, but you have to remember the chocolate added is luke warm. I needed mine thick enough to pipe cupcakes so I added 1/2 cup powdered sugar & 2 tablespoons meringue powder then chilled in the fridge for 30 minutes. Turned out perfect. Quality products make a huge difference. I used Mercken’s melting chocolate & Hershey’s cocoa powder. This will be my go to chocolate buttercream from now on. I made Black Forest cupcakes, yum! Thank you, Jenn for another wonderful recipe!
