Looking for buttercream recipes

Does anyone have any vanilla and chocolate buttercream recipes they would like to share? My family loves the whipped cream or cream cheese frostings I make, but it’s not the best for piping (I’ve tried stabilizers but still can’t leave those out for long).

A lot of the buttercream recipes sound like they are SUPER sweet, so I was hoping someone on here had a lighter type of recipe, that’s also easy and doesn’t require making anything on the stove top first?
