1-First Step: Preheat and prepare the pan Start by preheating your oven to 350°F. Grease a 9-inch cast iron skillet or a 9-inch cake pan well with butter or nonstick spray. If you want easier release, you can also line the bottom with parchment paper. This first step matters because the caramel topping sets quickly once baked, so the pan needs to be ready before you mix the batter.

2-Second Step: Make the buttery brown sugar topping Melt 1/2 cup unsalted butter, then mix it with 1 cup packed brown sugar until smooth. Spread this mixture evenly across the bottom of the pan. This becomes the sweet, sticky layer that will sit on top after the cake is flipped. For a deeper caramel flavor, stir the mixture until the sugar starts to dissolve a little in the warm butter.

3-Third Step: Arrange the pineapple and cherries Place the pineapple slices over the sugar mixture in a neat pattern. You can use 7 to 8 slices, depending on the pan size and the way you want the cake to look. Put one cherry in the center of each pineapple ring and tuck extra cherries into any open spaces. Pat the fruit dry first so the cake does not turn watery. This is one of the best ways to keep a pineapple upside down cake recipe from becoming soggy.

4-Fourth Step: Mix the cake batter In a medium bowl, cream 1/3 cup softened butter with 1 cup granulated sugar until light and fluffy. Beat in the eggs one at a time, then mix in the vanilla extract. In a separate bowl, whisk together the flour, baking powder, and salt. Add the dry ingredients to the butter mixture in batches, alternating with the pineapple juice. Begin and end with the dry ingredients so the batter stays smooth and even. Stir just until combined, because overmixing can make the cake dense.

5-Fifth Step: Pour and smooth the batter Carefully spoon the batter over the arranged fruit. Spread it gently so the top is even, but do not press too hard. The batter should cover the pineapple layer fully. If you are making this pineapple upside down cake recipe for a special event, this is the time to smooth the surface so the finished cake bakes evenly and looks neat when turned out.

6-Sixth Step: Bake until golden Bake for 35 to 45 minutes, depending on your oven and pan choice. The cake is ready when the top is golden and a toothpick inserted into the center comes out clean or with just a few moist crumbs. If the top starts browning too quickly, tent it lightly with foil during the last few minutes. Cast iron pans may brown a little faster, so keep an eye on the last stretch of baking.

7-Seventh Step: Cool briefly, then flip Let the cake cool in the pan for 10 to 15 minutes. This timing is important. If you flip too soon, the topping may run. If you wait too long, the sugar can harden and stick. Run a knife around the edges, place a serving plate over the pan, and turn it over in one steady motion. Lift the pan carefully and let the cake settle before removing it. If a few fruit pieces stick, gently place them back with a spatula.

8-Final Step: Slice and serve Serve the cake warm or at room temperature. The sweet pineapple topping is especially nice while it is still soft and glossy. For a richer dessert, add whipped cream or a scoop of vanilla ice cream. This pineapple upside down cake recipe also tastes great the next day, which makes it a smart choice for planning ahead.
