This homemade Caramel Apple Upside-Down Cake is a fluffy spice cake full of warm autumn flavors (like cinnamon, cloves and nutmeg) baked on top of brown sugar caramel apples.
Add in the eggs, one at a time, beating well after each addition.
Add in flour, cornstarch, baking powder, salt and all spices. Using your mixer (or a rubber spatula), mix until just combined (it’s okay if there’s still a little white in the batter).
*Instead of using a square pan, you can use a 9x9 deep dish circular pan (about the same depth as a 9x9 square baking pan).
