Can I use fresh pineapple instead of canned?
Fresh pineapple works but may release excess moisture; drain canned pineapple thoroughly and pat slices dry before arranging. Canned is more reliable for consistent results.
What's the best way to invert the cake without breaking it?
Cool the cake for 5 minutes after baking (still warm), then run a thin knife around the edges, place a serving plate on top, and invert in one confident motion. Let it sit for 30 seconds before lifting the pan.
Can I make this cake ahead of time?
Bake up to 2 days ahead and store covered at room temperature. Keep the cake in the pan until serving to preserve the caramelized topping.
Why is my caramel layer too hard or sticky?
Hard: overcooking; sticky: undercooking or excess pineapple juice. Bake until a toothpick inserted in the cake (not the topping) comes out clean, and ensure pineapple is well-drained.
Can I double this recipe?
Yes. Use two 9-inch pans with separate butter and brown sugar bases, or one 9ร13 pan. Increase baking time by 5โ10 minutes and check for doneness.
