How can I make a simple blueberry frosting?

no it would be too thin. you could just put the berries on top of the cake and frosting or make a homemade frosting and use some of the crushed berries to flavor it. good luck

You can, but it will be wetter, and you might add a little more powdered sugar. Otherwise, cook the berries until you get a thick syrup and add that, folding it in. A little more powdered sugar if it's too thin.

The best way is to get freeze-dried blueberries and powder them in the blender and add the powder with the sugar if you make frosting, or mix it into ready-made.
