Easy Chocolate Frosting

Super easy and super delicious, this chocolate frosting is sweet but not cloying, develops an outer layer but is still moist inside, has a great flavor, and comes together in minutes. It can be used as a filling too. A fantastic recipe!

  • Total Time: 5 minutes
  • Yield: 2 cups


  • 1/2 cup (115g) unsalted butter
  • 3.5 oz (100g) semi-sweet chocolate, chopped
  • 1 tablespoon unsweetened cocoa powder
  • 2 cups (250g) powdered sugar
  • 1 teaspoon vanilla extract or paste
  • 1/2 cup (120g) regular sour cream, at room temperature
  • Additional extracts, optional (I add coffee extract and sometimes pure almond extract)
  • Pinch of sea salt, optional


  1. Melt butter and chocolate (as for brownies) in the microwave (short 5-second spurts and mixing well each time) or on top of a saucepan with hot water being careful not to let it touch the bottom of the bowl. 
  2. Add sifted cocoa powder and powdered sugar in 2 parts and mix well until creamy.
  3. Add vanilla, salt, and other extracts if using.
  4. Add sour cream and mix very well. The final mixture should be creamy with no lumps. 
  5. Use directly as a frosting and/or filling. 
  6. Keep refrigerated, covered.
