Skillet Pineapple Coconut Upside-Down Cake: A Tropical Twist on a Classic

The scent of caramelized pineapple always transports me back to my childhood summers. My grandmother, a true queen of the kitchen, would often bake a simple pineapple upside-down cake in her well-worn cast iron skillet. It wasn’t fancy, but the combination of tangy fruit, buttery caramel, and moist cake was pure comfort. This recipe, a delightful twist on that classic with the addition of coconut, elevates the familiar flavors and textures to something truly special. It’s a guaranteed crowd-pleaser, and every bite brings back a wave of nostalgia.

Ingredients

1/4 cup butter
2/3 cup brown sugar
2 teaspoons lemon juice
8 slices pineapple, canned rings or fresh, about 1/2 inch thick
3/4 cup buttermilk
1/3 cup oil, vegetable or canola
1 teaspoon vanilla extract
3 eggs, lightly beaten
1 1/2 cups flour, all-purpose
2/3 cup sugar, granulated
1 teaspoon baking powder
1/4 teaspoon baking soda
1/2 teaspoon salt
1/2 teaspoon ground nutmeg
1/2 cup sweetened flaked coconut

Equipment Needed

10-inch cast iron skillet
Large mixing bowl
Whisk
Sifter or fine-mesh sieve
Measuring cups and spoons
Flat plate for inverting the cake
Knife

Instructions

Preheat your oven to 350°F (175°C). While the oven is heating, prepare your cast iron skillet.
Melt the butter in the 10-inch cast iron skillet over medium heat on the stovetop.
Add the brown sugar to the melted butter and stir continuously until the mixture becomes bubbly and the sugar is dissolved.
Stir in the lemon juice and continue to stir until the caramel is smooth and glossy. Remove the skillet from the heat.
Arrange the pineapple slices evenly over the caramel in the skillet. You can use whole rings or cut them into smaller pieces to fit snugly. Don’t worry about perfection, just ensure they cover the base of the skillet.
Let the pineapple and caramel mixture sit and cool slightly while you prepare the cake batter. This will prevent the caramel from hardening too quickly and allow the pineapple to soften slightly.
In a large mixing bowl, combine the buttermilk, oil, vanilla extract, and lightly beaten eggs. Whisk these wet ingredients together until they are well combined.
In a separate bowl, sift together the flour, sugar, baking powder, baking soda, salt, and ground nutmeg. Sifting ensures that there are no lumps and that the dry ingredients are evenly distributed, resulting in a lighter cake. If you don’t have a sifter, you can use a fine-mesh sieve.
Add the sifted dry ingredients to the wet ingredients all at once.
Whisk the mixture until it is smooth and just combined. Be careful not to overmix, as this can lead to a tough cake. A few small lumps are okay.
Fold in the sweetened flaked coconut. Ensure it’s evenly distributed throughout the batter.
Carefully pour or ladle the batter over the pineapple slices in the skillet, spreading it evenly to cover the fruit.
Bake in the preheated oven for 30 to 35 minutes, or until a toothpick inserted into the center of the cake comes out clean. The cake should be golden brown and spring back lightly when touched. Start checking for doneness around 30 minutes.
Cool the cake in the skillet for 30 minutes on a wire rack. This allows the caramel to set slightly and makes it easier to invert the cake without it falling apart.
After cooling, run a knife around the edge of the cake to loosen it from the sides of the skillet.
Place a flat plate over the skillet and carefully invert the cake onto the plate. The caramel and pineapple should now be on top. If any pineapple slices stick to the skillet, gently remove them and place them back on top of the cake.
Serve the cake warm or at room temperature. It’s delicious on its own or with a dollop of whipped topping or a scoop of vanilla ice cream.

Expert Tips & Tricks

For extra caramel flavor, you can add a tablespoon of molasses to the caramel mixture in the skillet.
If you don’t have buttermilk, you can make a substitute by adding 1 tablespoon of lemon juice or white vinegar to 3/4 cup of milk. Let it sit for 5 minutes to curdle slightly before using.
To prevent the cake from sticking, make sure your cast iron skillet is well-seasoned. If you’re concerned about sticking, you can also line the bottom of the skillet with parchment paper before adding the butter and brown sugar.
If the top of the cake starts to brown too quickly, tent it loosely with aluminum foil during the last 10-15 minutes of baking.
Don’t overbake the cake, as it will become dry. It’s better to err on the side of slightly underbaked, as the cake will continue to cook slightly as it cools.

Serving & Storage Suggestions

This Skillet Pineapple Coconut Upside-Down Cake is best served warm or at room temperature. A dollop of freshly whipped cream or a scoop of vanilla ice cream complements the tropical flavors beautifully. For a truly decadent experience, consider drizzling a little extra caramel sauce over each slice.

Leftover cake can be stored in an airtight container at room temperature for up to 2 days, or in the refrigerator for up to 4 days. To reheat, you can microwave individual slices for a few seconds or warm them in a low oven. The cake can also be frozen for up to 2 months. Wrap it tightly in plastic wrap and then in aluminum foil. Thaw overnight in the refrigerator before serving.

Spices: Experiment with different spices like cinnamon, ginger, or cardamom.
Dairy-free: Substitute the buttermilk with a plant-based alternative like almond milk or soy milk mixed with 1 tablespoon of lemon juice or vinegar. Use a plant-based butter substitute.

FAQs (Frequently Asked Questions)

Q: Can I use fresh pineapple instead of canned?
A: Yes, absolutely! Fresh pineapple will add a slightly tangier flavor. Make sure to peel, core, and slice the pineapple into ½-inch thick rings before arranging it in the skillet.

Q: My caramel hardened before I could pour the batter. What should I do?
A: Gently reheat the skillet over low heat on the stovetop, stirring the caramel until it melts again. Be careful not to burn it.

Q: How do I know when the cake is done?
A: Insert a toothpick into the center of the cake. If it comes out clean or with a few moist crumbs, the cake is done. Avoid overbaking, as this will result in a dry cake.

Q: Can I make this cake ahead of time?
A: While best served fresh, you can bake the cake a day ahead of time and store it at room temperature, covered.

Q: The pineapple stuck to the bottom of the skillet when I flipped the cake. What went wrong?
A: Make sure to cool the cake for the recommended 30 minutes before inverting it. Also, running a knife around the edge of the cake helps to loosen it. If pieces still stick, simply place them back onto the cake after inverting.
