Paleo Caramel Apple Upside-Down Cake (AIP Friendly)

After sharing my Pumpkin Salted Caramel Sauce recipe, I promised you’d see it again. This time it becomes the star of a decadent fall dessert—perfect while apples are at their best.

This Paleo Caramel Apple Upside Down Cake is dairy-free, egg-free, and AIP-friendly, loaded with sweet apples, sticky salted caramel, and warm cinnamon. I loved it so much I made it for my mom’s birthday and for Halloween, and it was a hit every time.

If you don’t already have Pumpkin Salted Caramel Sauce on hand, make a batch, then follow along with this Paleo Caramel Apple Upside Down Cake recipe. One generous slice of this warm apple cake drizzled with caramel could easily replace traditional holiday pies.

Upside-down cakes have a classic charm. Their glossy fruit top and the satisfying flip make them impressive, but they’re actually straightforward to assemble and turn out beautifully. This fall-inspired version is no exception—don’t be intimidated; it’s easy to bake and invert.

Baking on the autoimmune protocol (AIP) can be tricky. Reproducing good texture without gluten, dairy, or eggs takes experimentation. I’ve used gelatin “eggs” in other recipes, but for this apple cake applesauce proved to be the perfect egg substitute—adding moisture and complementary apple flavor.

This cake is packed with apples: applesauce to replace eggs, diced apples folded into the batter, and sliced apples caramelized on top for the finished look. Use firmer, crisp varieties such as Stayman Winesap, Jonagold, Pink Lady, or Granny Smith for best texture.

Begin with your Pumpkin Salted Caramel Sauce and apples. Peel, core, and thinly slice two large apples and place them in a skillet. Peel, core, and dice the remaining apple for the batter.

Cook the sliced apples with half of the caramel sauce for about five minutes, until they soften slightly. Avoid overcooking because they’ll finish baking in the oven.

Prepare a 9-inch round cake pan by greasing it well with coconut oil and lining the bottom with a circle of parchment. Grease the parchment as well so the topping releases cleanly. Proper greasing makes flipping the cake much easier.

Arrange the caramel-coated apple slices across the bottom of the prepared pan. Spread them evenly or create a decorative pattern—perfection isn’t necessary since you’ll add more caramel after baking.

In one bowl whisk the dry ingredients and in another combine the wet ingredients, reserving the diced apple and apple cider vinegar for last. Lightly toss the diced apple with arrowroot powder to prevent excess moisture, then fold the pieces into the batter. Add the apple cider vinegar at the end to react with the baking soda and help the cake rise.

The batter will be thick and dense—this is expected. Gently spread it over the caramel apples so it covers evenly.

Bake at 350°F for 30–35 minutes, or until a toothpick inserted into the center comes out clean. Once browned, remove the cake and let it cool for 15–20 minutes. Running a knife around the edges while it cools helps release the cake.

When the cake has cooled slightly, invert it onto a plate or cake stand. If it sticks, tap the pan gently to release it. Peel off the parchment and admire the glossy caramel apple topping. Finish with the remaining Pumpkin Salted Caramel Sauce to taste and serve warm.

This cake is intended to serve 6–8, though it’s so tempting many people will want seconds. It’s rich, comforting, and addictive—perfect for fall gatherings or holiday dessert tables.

This reliable, delicious dessert is ideal for holidays or any time you want a cozy fall treat. Even without dietary restrictions, it’s worth making and sharing.
