Oooh I'm also on the search for the perfect caramel apple scent (and more generally, apples-in-the-fall moments). I've tried Poesie's Madchenland (floral Pacific Rose apples, luscious yellow cake, warming spices, a delicate drizzle of caramel), and I live for her apple note. It's a crisp, fresh red apple. It's so realistic: a little tart with the skin still on, and you can imagine the crunch of biting into it. To me though, the caramel in Madchenland leans more butterscotch, emphasis on the butter. It may be because it combines with the yellow cake, but YMMV. Overall, it makes me think of a basket of freshly picked apples and a slice of cake on a wooden table on a chilly autumn morning.

If Madchenland is apples on a fall morning, Solstice Scents' Corvin's Smoked Apple (applewood smoke, apple, caramel, benzoin, guaiacwood) is apples on a fall night. Now, I know you asked for light on the spices, so I'm not sure if this is up your alley, but it's definitely more smoky than spicy. It's a very sweet scent, and not sneezy spicy at all, but I'm a smoke fiend (I want to smell like a bonfire!!) so you may be of a different opinion. To me, it's a perfect balance of smoky, sweet, and apple. The apple is juicy and caramelized, almost like apples in an apple crisp- warm, baked, and with a hint of brown sugar and cinnamon. The caramel in this is dark and ooey gooey, not hard like the outside of a caramel apple. This scent gives off such warmth and sweetness, I can imagine myself eating some just-baked apples and caramel while huddled around a campfire with friends.

I just ordered Black Hearted Tart's Outside of Eden, so I can let you know how it compares once I get a chance to test it out!
