Why This Recipe Works for Overlanders
Foil packet pineapple upside down solves the problem of wanting the flavor of a classic upside-down cake without packing a cake pan, an oven, or a mixing bowl. Canned pineapple rings, brown sugar, and butter caramelize together in foil. The packet does in 20 minutes what a full cake usually takes an hour to build.
I started making this as the last dessert of the series because it closes the loop nicely on the fruit-based packets. The caramelized brown sugar syrup that forms around the pineapple is the same effect a cake pan produces. It just skips the batter and the bake time.
This recipe leans into what makes camp desserts work in the first place. It uses shelf-stable canned pineapple rather than fresh fruit that needs a cooler and careful handling. If you want a shorter, simpler dessert on the same coal bed, try our Foil Packet Campfire Apples. It uses the same medium coal stage with a stuffed whole fruit instead.
Canned pineapple keeps for months in the cook box without refrigeration. This recipe works even on a trip where the cooler is already packed tight with other meals.
Equipment You Need
This recipe uses the same core kit as every foil packet camping recipe. Heavy-duty aluminum foil at 0.94 mil (Reynolds Wrap Heavy Duty) handles the coal contact without tearing. Long-handled tongs pull the packet off coals without burned knuckles. Heat-resistant gloves rated to at least 500F handle the flip. A can opener gets the pineapple rings out of the can, and most cook kits already carry one.

Ingredients
Serves 4 | Prep 10 min | Cook 20 min | Medium coals
- 1 can pineapple rings, drained
- 1/4 cup brown sugar
- 4 tablespoons butter, cut into pats
- 4 maraschino cherries
- Foil, one large sheet or one per serving
Step-by-Step Instructions
Home Prep
Drain the pineapple rings at home and pack them in a sealed container so the packet does not carry extra liquid to camp. Measure the brown sugar into a small container ahead of time. Cut the butter into pats and keep it in the cooler along with the cherries.
At camp, lay the pineapple rings flat on a sheet of foil in a single layer. Sprinkle the brown sugar evenly over the rings and tuck a pat of butter onto each one. Place a maraschino cherry in the center of every ring. Fold the foil into a flat-pack seal, crimping the edges so the caramelizing sugar stays inside during the cook.
At Camp
Build a bed of medium coals, glowing orange with a thicker layer of gray ash than a hot fire needs. Place the flat-packed pineapple directly on the coals and leave it undisturbed. Flipping can spill the melted sugar out of the seam.
Cook 18 to 20 minutes, until the sugar and butter caramelize into a syrup around the fruit. Open carefully, since trapped steam and hot syrup release fast from the seam. Serve the caramelized rings over pound cake slices, or spoon them over vanilla ice cream if a fridge is nearby.
Coal Bed Math
Coal temperature determines whether the sugar caramelizes evenly around the pineapple without burning in this recipe’s 18 to 20 minute window. Use this table to read your coal bed before placing packets.
| Coal Stage | Temperature | Best For |
|---|---|---|
| Hot | 500F+ | Searing, quick shrimp packets |
| Medium-Hot | 400-500F | Taco meat, potatoes and onions |
| Medium | 350-400F | Pineapple upside down, peach crumble |
| Medium-Low | 250-350F | Chocolate fondue |
Field Tips
Drain the pineapple rings well before packing them in foil. Extra juice from the can dilutes the caramelized syrup and can turn the cook into more of a poach than a proper caramelization.
Lay the rings in a single layer rather than stacking them. Stacked rings shield the bottom layer from the coals and caramelize unevenly. A flat single layer gets even heat across every piece.
Store the brown sugar, cherries, and butter away from your sleeping area overnight, not just in a sealed bag in the cook box. Sugary, scented food draws bears and other wildlife into camp, especially in bear country like the Sierras or Big Bear. The National Park Service has guidance on storing scented food safely on its bear safety food storage page. It is worth a read before any trip through bear country.
Pack a few slices of pound cake if planning to serve this the traditional way. Pound cake holds up well in a dry box and turns the caramelized pineapple into a full dessert instead of a topping.

Variations and Substitutions
The base foil packet pineapple upside down build takes well to swaps once the layering feels natural. Try one change at a time so the cook time stays predictable.
- Coconut addition: Sprinkle shredded coconut over the rings before folding for a tropical finish.
- Rum extract swap: Add a few drops of rum extract to the brown sugar for a deeper, spiced flavor.
- Fresh pineapple swap: Use fresh pineapple rings instead of canned if the cooler has room and the fruit is ripe.
- Cinnamon addition: Add a pinch of cinnamon to the brown sugar for a warmer background flavor.
- Nut topping: Sprinkle chopped pecans over the rings alongside the cherries for extra crunch.
- Dark brown sugar swap: Use dark brown sugar instead of light for a deeper caramel flavor.
- Stuffed fruit version: Skip the sliced rings for a stuffed whole fruit instead. See our Foil Packet Campfire Apples for that approach.
Storage and Leftovers
Foil packet pineapple upside down tastes best warm off the coals and does not hold well as leftovers. The caramelized syrup thickens and turns sticky as it cools, losing the glossy texture it has fresh off the coals.
If a packet does not get finished, scoop the pineapple and syrup into a small container. Store it in the cooler for up to two days rather than saving it in the foil. The mixture works well spooned over oatmeal or pancakes the next morning. A dedicated trash bag for used foil keeps the drawer system clean and supports a Leave No Trace pack-out.
Frequently Asked Questions
How do you know when foil packet pineapple upside down is done?
Check that the brown sugar and butter have turned into a glossy caramel syrup around the pineapple. Peel back a corner of the foil to check, then reseal and cook a couple more minutes if the sugar still looks grainy.
Why did the syrup turn watery instead of caramelizing?
The pineapple rings likely were not drained well enough before packing. Extra juice from the can dilutes the brown sugar and butter, so drain the rings thoroughly at home.
Can you use fresh pineapple instead of canned?
Yes. Fresh pineapple rings work well if the cooler has room, though canned rings are easier to pack and travel without bruising.
What is the difference between this and a real upside-down cake?
This recipe skips the cake batter entirely and serves the caramelized pineapple over pound cake slices instead. It is faster and needs no oven or cake pan.
How do you keep bears away from the brown sugar and cherries?
Store sugary, scented ingredients away from your sleeping area overnight. Use a sealed container or vehicle rather than a tent, especially in bear country like the Sierras.
Can you make this recipe without maraschino cherries?
Yes. The cherries are a classic garnish, but the recipe caramelizes just as well without them if they are not on hand.
What pairs well with foil packet pineapple upside down?
Pound cake slices are the traditional pairing, or vanilla ice cream works well if a fridge like an ICECO is nearby at base camp.
