Gram's Chocolate Frosting
This is easy ...
1 cup of butter—2 sticks (room temp)
3 1/2 cups powdered sugar
1/2 cup unsweetened cocoa powder
3 Tablespoons heavy cream or half and half (or milk)
1/4 teaspoon salt
2 teaspoons vanilla
I've made it without vanilla ... but ... yeah, it's great.
Beat the butter, then slowly add the sugar ... add the vanilla and salt then cocoa a bit at a time, add milk or cream as needed for spreadable consistency.
Nothing to cook ... it's ready to use.
