King Arthur Pineapple Upside-Down Cake (Recipe)
King Arthur’s pineapple upside-down cake bakes in a 9-inch round pan at 350°F (175°C). Melted butter and brown sugar form the topping beneath drained pineapple and cherries; batter goes over the fruit. Bake until the cake springs back and a tester comes out clean, then rest briefly and invert onto a rimmed plate.
The appeal is immediate: sweet pineapple, soft cake, and a glossy brown-sugar topping, all revealed in one careful turn. The main trick is timing. Invert too soon and the cake may break; wait until it is fully cool and the topping may stick. A sound pan, well-drained fruit, and a short rest make the process easier to manage.
Pan material, oven setup, and surface preparation
A 9-inch round cake pan gives the batter and topping the space the recipe is designed for. Choose a pan that is oven-safe at 350°F, deep enough to hold the batter and syrup, and level so the cake bakes evenly. Preheat the oven fully and set a rack near the center.
Light-colored aluminum spreads heat well and is a reliable choice. Steel, aluminized steel, and oven-rated nonstick pans can also work if they are the correct size and their makers approve use at this temperature. Pan material affects browning and release, but it does not change the oven setting.
| Pan choice | What to check | Practical note |
|---|---|---|
| Light-colored aluminum | 9-inch diameter and adequate depth | A dependable option for even baking |
| Steel or aluminized steel | Oven rating and pan size | Suitable if rated for 350°F |
| Nonstick | Coating temperature limit | Follow the maker’s care directions; avoid aerosol spray |
| Silicone | Temperature rating and support | Use only if rated for 350°F, set on a rigid sheet pan |
Lightly grease the pan as the recipe directs. Don’t assume that a nonstick coating removes the need for preparation. Avoid substituting a skillet or a pan with a much larger or smaller capacity: the batter depth and bake time would change. Induction compatibility is not relevant because the cake bakes in the oven.
Key step: Confirm the pan’s size, depth, and temperature rating before you begin.
Topping assembly, batter mixing, and baking
The topping is the layer of butter, brown sugar, pineapple, and cherries that becomes the top after you invert the cake. Drain the fruit well, spread the sugar evenly, and mix the batter only until combined. These steps help limit excess liquid and keep the cake tender.
Arrange the fruit and make the batter
Use the quantities in the current King Arthur recipe, including its specified amount of pineapple and cherries. Melt the topping butter gently, distribute it in the prepared pan, and scatter the brown sugar in an even layer. Arrange the drained pineapple and cherries over it. Patting the pineapple dry helps remove surface moisture; don’t press the fruit down into the sugar.
Prepare the batter as written. Once flour is added, mix just until no dry streaks remain. Overmixing can make a cake tougher. Spoon the batter over the fruit in small portions, then spread it gently so you don’t shift the arrangement.
Bake and check for doneness
Heat the oven to 350°F (175°C) and bake on the center rack. Use the bake-time range in King Arthur’s recipe as a guide, not a guarantee. Pan material, oven accuracy, and fruit moisture can affect how quickly the cake is done.
Check the cake portion, not the fruit or a pocket of syrup. A tester inserted into the cake near the center should come out clean or with a few moist crumbs. The center should also spring back lightly when touched. If the tester shows wet batter, bake a little longer and check again.
| What you notice | What it may mean | What to do |
|---|---|---|
| Tester has wet batter | The cake needs more time | Continue baking and check again soon |
| Tester has a few moist crumbs | The cake may be done | Check that the center also springs back |
| Tester passes through fruit or syrup | The result may be misleading | Test a nearby area of cake instead |
| Top browns before the center is set | The cake needs more baking | Follow the recipe’s guidance and watch the surface |
Key step: Use the recipe’s time range to plan, then use the cake’s texture and a tester to judge doneness.
Unmolding, cleaning, and pan care
Unmolding means turning the baked cake out of its pan so the fruit topping faces up. The brief rest lets the cake settle, while the topping is still soft enough to release. Follow the rest interval in the recipe; avoid leaving the cake in the pan until it is fully cool.
Set a rimmed serving plate over the pan. With oven mitts on, hold the plate and pan together, then turn them over in one controlled motion. Keep your hands clear of any hot syrup that may escape. Lift the pan carefully. If fruit remains behind, use a spatula to place it back on the cake while the topping is still warm.
If the edge needs help releasing, run a thin, nonmetallic or silicone tool around the inside of the pan. Don’t use a metal knife on nonstick or coated bakeware. Once the pan is empty, let it cool before washing. Never pour cold water onto a hot pan; a rapid temperature change can warp metal or damage a coating. Use a soft sponge rather than an abrasive pad.
What if the topping sticks?
A topping that sticks or tears often means the cake cooled too long in the pan, the fruit was not drained well, or the pan needed better preparation. A brief rest followed by a careful inversion is the useful middle ground: not so hot that handling is unsafe, and not so cool that the sugar firms against the pan.
For a practical example, if the cake is done but the topping seems to be holding at the edge, set the serving plate in place first. Loosen the edge gently, then invert; don’t shake the pan hard or pry under the fruit. If a few pieces stay behind, arrange them on top. The cake can still serve neatly.
Key step: Let the cake rest for the recipe’s short interval, then invert with the plate securely aligned.
Serving, storage, and presentation
Serve the cake after it has cooled enough to slice without disturbing the topping. A rimmed plate helps catch syrup, and a sharp knife makes cleaner portions. For a neat cut, wipe the blade between slices if sticky topping builds up on it.
| Situation | Best approach |
|---|---|
| Serving soon after baking | Rest as directed, invert, then cool before slicing |
| Slices pull at the topping | Let the cake cool further and use a clean knife |
| Saving leftovers | Refrigerate promptly in a covered container |
| Releasing a stuck piece | Use a thin nonmetallic tool, not a metal knife |
For leftovers, cover the cake and refrigerate promptly. The fruit topping is moist, so don’t leave the cake out for an extended period. For best texture, let a chilled slice lose some of its refrigerator chill before serving, while following safe food-handling practices.
Baking scenarios that help with timing
These are practical examples, not reports from named bakers. If your pan is dark, the cake may brown differently than it would in light aluminum, so watch the cake as it approaches the recipe’s stated bake-time range. If your pineapple is especially wet, drain and pat it dry before arranging it. If you need to transport the cake, invert it at home onto a rimmed plate and let it cool before covering.
A level oven rack also matters. If the pan sits at an angle, syrup and batter may collect unevenly. Check that the rack is secure and centered before placing the pan in the oven.
Key step: Let the cake cool before covering or slicing, and keep leftovers covered in the refrigerator.
Frequently asked questions
These answers cover the main decisions that affect this cake: pan choice, oven temperature, doneness, release, and storage. Follow the current King Arthur recipe for ingredient quantities and its stated bake-time range, then use the checks below to respond to what you see in your own oven.
Can I use a pan other than a 9-inch round cake pan?
Use the specified 9-inch round pan for the closest match to the recipe. A different size or shape can change the batter depth and bake time, so don’t substitute without adjusting the recipe.
What oven temperature should I use?
Bake at 350°F (175°C). Preheat the oven fully and place the pan on a rack near the center.
How do I know when the cake is done?
Insert a tester into the cake portion, avoiding fruit and syrup. It should come out clean or with a few moist crumbs, and the center should spring back lightly.
Should I drain the pineapple?
Yes. Drain it well, then pat away surface moisture if needed. Excess liquid can make the topping wetter and may affect the cake’s texture.
Can I use a nonstick pan?
Yes, if it is a 9-inch round pan rated by its maker for 350°F. Follow the maker’s care instructions, and don’t use aerosol spray on the nonstick surface.
When should I invert the cake?
Invert it after the short rest specified in the recipe. Waiting until the cake is fully cool can make the butter-sugar topping firm against the pan; turning it out immediately risks burns and breakage.
What should I do if fruit sticks to the pan?
Loosen the edge gently with a nonmetallic or silicone tool, then invert the cake onto a plate. If a piece of fruit stays behind, lift it out carefully and place it back on the topping.
Can I use a silicone pan?
Only if the pan is explicitly rated for 350°F and is the correct size. Set it on a rigid sheet pan for support, and follow its maker’s instructions for release.
How should I store leftover cake?
Cover it and refrigerate it promptly. Keep it covered until serving so the cake does not dry out.
Can I cool a hot pan faster with cold water?
No. Don’t pour cold water onto or into a hot pan. A sudden temperature change can warp metal or damage a coating.
