The flavor and texture from this cake comes from finely diced apples, melted butter, and loads of spice. I added sour cream to keep it extra tender as well as brown sugar for more depth of flavor. It’s the apple spice cake that's familiar and beloved by all this season.
Whipped salted caramel is a revelation! It’s light and smooth, not too sweet, and has a distinct toasted sugar flavor that is sometimes lost in other caramel buttercreams.
