Paleo Caramel Apple Upside Down Cake (AIP)

This cake features my Pumpkin Salted Caramel Sauce woven into a cozy, spiced apple upside down cake — ideal while fall apples are at their best. It’s dairy-free, egg-free, and compatible with the autoimmune protocol (AIP), yet rich, sticky, and full of cinnamon and warm apple flavor.

This Paleo Caramel Apple Upside Down Cake is an allergy-friendly cake packed with apples, salted caramel, and spice. I loved it so much I used it as my mom’s birthday cake, and it was an instant family favorite. It’s also a lovely seasonal option for Halloween or Thanksgiving.

Upside down cakes have a classic charm: a glossy fruit topping and the satisfying reveal when you flip the pan. While they might seem fussy, this version is straightforward to assemble and flip — and it’s especially rewarding when the caramelized apples glisten on top.

Baking on the autoimmune protocol can be tricky because you’re avoiding gluten, dairy, and eggs. Instead of relying on gelatin eggs, for this cake I found applesauce to be an excellent egg replacer — it adds moisture and complements the apple flavor beautifully. The result is a tender, flavorful crumb that pairs perfectly with the caramel topping.

This cake is genuinely loaded with apples: applesauce as the binder, diced apples folded into the batter, and thin apple slices caramelized on top. For the topping, choose firm, crisp varieties such as Stayman Winesap, Jonagold, Pink Lady, or Granny Smith so they hold their shape and provide a pleasant contrast to the soft cake.

To begin, you’ll need pre-made Pumpkin Salted Caramel Sauce and three large apples. Peel, core, and thinly slice two apples for the topping and dice the third to fold into the batter. Cook the sliced apples with half of the caramel sauce in a skillet for about five minutes, just until they begin to soften. Avoid overcooking since they will finish baking in the oven.

Line a 9-inch round cake pan with parchment and grease both the pan and the parchment well with coconut oil (or a preferred dairy-free fat). Good greasing helps the cake release cleanly when inverted. Arrange the caramel-coated apple slices in the pan in a single layer — a rustic pattern is fine, since you’ll drizzle more caramel over the top after baking.

Mix dry ingredients in one bowl and wet ingredients in another, holding the diced apple and apple cider vinegar until the end. Lightly coat the diced apple with arrowroot starch before folding it into the batter to prevent it from sinking. Add the apple cider vinegar last so it can react with the baking soda and give the cake lift.

The batter will be thick, which is expected. Spread it carefully and evenly over the caramelized apples and bake at 350°F (175°C) for 30–35 minutes, or until a toothpick inserted near the center comes out clean. Let the cake rest for 15–20 minutes, then run a knife around the edge to loosen it before flipping.

Invert the cake onto a plate or cake stand in one smooth motion; if it sticks, tap the pan gently until it releases. Peel off the parchment and admire the shiny, caramelized apple topping. Finish with an extra drizzle of Pumpkin Salted Caramel Sauce and serve warm or at room temperature.

This cake serves about 6–8 people, though it’s often devoured quickly. It makes a comforting centerpiece for holiday tables or a cozy weekend dessert when you want something special without a lot of fuss.

Whether you follow AIP or simply prefer grain- and dairy-free baking, this cake is a dependable, delicious option that delivers classic apple-and-caramel flavors in a naturally wholesome way.
