An old-fashioned apple crisp ... such as Honeycrisps (sweet), Granny Smiths (tart), Cortlands (in between). Lemon juice adds a bit of extra zing. Apple crisp is almost endlessly adaptable.
It's fun to make desserts that are new and trendy, but there's nothing like the old-fashioned ... chewy and crisp, just like the kind you might remember from holidays at Grandma's house.
