For a small cake (9x9-inch cake or batch of cookies)
3ozunsweetened chocolate
5tablespoonsunsalted buttersoftened
3cupspowdered sugar
1teaspoonvanilla
2–3tablespoonsmilk
Pinchof salt
Instructions
Place the unsweetened chocolate in a microwave-safe bowl. Microwave in 30 second intervals until melted. Let cool to room temperature.
Add the softened butter, powdered sugar, vanilla, and 2 tablespoons milk into the bowl with the melted chocolate.
Use a handheld mixer to mix until the frosting is light and fluffy. Add an additional tablespoon of milk if the mixture looks too stiff or grainy.
Spread the frosting over cake, cookies, brownies, etc.
Notes
If you're using salted butter, just leave out the pinch of salt. Be sure to start with softened butter. Otherwise, the frosting will be lumpy. If the frosting is grainy, add a splash more milk. If the frosting looks wet, add a couple tablespoons more powdered sugar.The frosting (when on top of cake or cookies) can be kept at room temperature for up to one week, tightly covered.If you make the frosting ahead of time, refrigerate it to protect it from any heat sources in your kitchen. It'll keep in the fridge for several days, tightly covered. Let it come to room temperature and beat the frosting again with a hand mixer before spreading on any baked goods.
