From the roundup: 24 Easy Fall Desserts Recipes to Bake This Season
Sunday afternoon around 2:00 is when I pull out the sheet pan and get this spiced apple molasses cake going, usually while the younger kids are doing quiet time and I can actually measure without someone hanging on my arm. The molasses does something interesting to the batter: it deepens the apple and cinnamon flavor in a way that plain brown sugar just does not, and the cake comes out with a darker crumb than you expect from something this simple. I learned after the first bake to pull it at exactly 28 minutes because the edges set faster than the center, and a dry center is the one thing that kills this cake. Leftovers the next morning, cold from the pan with a cup of coffee, are genuinely worth planning for.
Why I keep coming back to this one
The first time I made this, I waited too long before flipping it. I got distracted by something one of the kids needed, and by the time I got back, the caramel had cooled and seized to the pan. We ate it straight out of the skillet with spoons, which honestly was not the worst outcome, but I learned to set a timer for exactly 10 minutes and not walk away. Now I keep my oven mitts on the counter before the cake even goes in the oven.
My husband is not usually a cake person, but he asks for this one by name in October. That is enough of an endorsement for me.
Why you will love this
- The caramel forms right in the skillet, so there is no separate pot to wash and no candy thermometer needed.
- Flipping it reveals a finished, glossy top, no frosting, no decoration, nothing extra required.
- The cast iron holds heat evenly through the bake, which gives the caramel a deep, consistent color all the way to the edges.
- Leftovers reheat well in the microwave in about 25 seconds and taste just as good the next day.
- It serves 8 from a single pan, which makes it practical for a dinner party or a weeknight when you want something worth passing around the table.
Tips for success
- Grease the sides of the skillet lightly with butter before you start the caramel layer. The caramel covers the bottom, but the sides need a little help releasing cleanly when you flip.
- Slice the apples to a consistent 1/4 inch thickness. Thicker slices stay undercooked in the center; thinner ones turn mushy before the cake is done.
- Do not overmix once the flour goes in. Mix on low and stop as soon as you see no dry streaks. Overmixing is the main reason this style of batter turns out tough.
- Set a timer for 10 minutes the moment the cake comes out of the oven, and have your serving plate ready before the timer goes off. The flip window is real, and it closes fast.
If the flip goes sideways
- If caramel sticks to the pan, set the empty skillet over low heat for 30 seconds. The residual warmth loosens it enough to pour over the top of the cake.
- If a few apple slices stay behind in the pan, just press them back into place on top of the cake while everything is still warm. Nobody will know.
- If the cake cracks during the flip, spoon warm caramel from the skillet over the top. It covers a lot and the slices still look good on a plate.
- If the bottom of the cake (now the top after flipping) looks pale, it just means the caramel layer is thinner in that spot. Taste is not affected.
Substitutions
Granny Smith apples are worth using here because their tartness balances the caramel, but Honeycrisp or Braeburn both work if that is what you have. Avoid very soft apples like McIntosh since they break down too much during the bake. If you do not have buttermilk, add one tablespoon of white vinegar to a half cup of whole milk and let it sit for five minutes before using. Sour cream works too, in the same amount, just thin it slightly with a splash of milk so the batter spreads evenly.
No cast iron skillet? Make the caramel in a small saucepan, pour it into a greased 9-inch round cake pan, arrange the apples, then add the batter. The flip works the same way, just be sure the pan is well greased on the sides. A gluten-free 1:1 baking flour blend also works in place of all-purpose flour without changing the method.
Make-ahead and storage
You can peel, slice, and toss the apples with the cinnamon and nutmeg up to a day ahead. Store them covered in the fridge, and give them a quick stir before arranging them in the skillet. That is the most time-consuming part of the prep, so getting it done the night before makes baking day much faster. The caramel layer is best made fresh since it sets up quickly once it cools.
Cover leftover cake and store it at room temperature for up to 2 days, or refrigerate for up to 4 days. The caramel layer stays soft and saucy in the fridge, which is actually one of the better things about this cake the next day. Reheat individual slices in the microwave for 20 to 25 seconds. Skip the freezer on this one: the apple layer releases water as it thaws and the caramel texture does not recover.

Ingredients
Equipment
Method
- Preheat your oven to 350 degrees F. Place your 9-inch cast iron skillet on the stovetop over medium heat. Add the 4 tablespoons of butter for the caramel and let it melt completely. Add the brown sugar and sea salt, then stir until combined. Cook for about 2 minutes, stirring gently, until the mixture is bubbling and slightly thickened. Remove from heat.
- Toss the apple slices with cinnamon and nutmeg in a bowl. Arrange them over the caramel in the skillet in a single, slightly overlapping layer. Start at the outside edge and work inward, fanning the slices like a pinwheel if you like a pretty pattern. Set the skillet aside.
- Make the cake batter. In a medium bowl, whisk together the flour, baking powder, and salt. In a large bowl, beat the room-temperature butter and granulated sugar with a hand mixer on medium-high for about 3 minutes until light and fluffy. Add the eggs one at a time, mixing well after each. Add the vanilla and mix to combine.
- Add the dry ingredients and buttermilk alternately to the butter mixture: add half the flour, mix on low until just combined, pour in all the buttermilk, mix gently, then add the remaining flour and stir just until no dry streaks remain. Do not overmix or the cake will be tough.
- Pour the batter over the apple layer in the skillet and use a spatula to spread it evenly all the way to the edges. Bake for 40 to 45 minutes, until the top is golden brown and a toothpick inserted in the center comes out clean. The edges will have pulled away slightly from the pan.
- Let the cake rest in the skillet for exactly 10 minutes. Do not wait longer or the caramel will harden and stick. Run a thin knife around the entire edge of the cake to loosen it. Place a large flat serving plate over the skillet, hold both firmly with oven mitts, and flip in one confident motion. Leave the skillet sitting on top of the cake for 30 seconds so the caramel drips down, then lift it straight up.
- Serve warm or at room temperature. The caramel layer on top will look shiny and golden with the apple slices visible. Spoon any extra caramel from the skillet over the top of the cake. Pairs beautifully with vanilla ice cream or lightly sweetened whipped cream.
