🍍 Upside Down Pineapple Cake in a Jar Recipe

Yield: 4-6 pint jars (depending on jar size) | Prep time: 15 minutes | Bake time: 30 minutes at 350°F

🏆 "I did it! I canned upside down pineapple cake in a jar. Oh, it was really good!" — The maker's first successful batch.

📦 Ingredients

Ingredient	Amount
Maraschino cherries

(with stems optional)1 per jar (about 4-6 total) Canned crushed pineapple (in juice, not syrup) Pineapple juice (from the can) Brown sugar (light or dark) Butter-flavored cooking spray (Pam) Pineapple upside down cake mix (Walmart or any brand) Wide-mouth pint mason jars (oven-safe, 4-6 jars)

🥫 Equipment Needed

• 4-6 wide-mouth pint mason jars (Ball, Kerr, or any oven-safe brand)
• Large baking dish or rimmed baking sheet (to hold jars while baking)
• Small saucepan
• Mixing bowl for cake batter
• Measuring cups and spoons
• Oven mitts (jars are HOT!)

📝 Step-by-Step Instructions

Step 1 – Sterilize the Jars

Wash jars, lids, and rings in hot soapy water. Sterilize by boiling for 10 minutes or running through a dishwasher cycle. Let them dry completely before using.

Step 2 – Spray with Butter Spray

Spray the inside of each jar with butter-flavored Pam spray (or any baking spray with flour). This ensures the cake releases easily when flipped over. Don't skip this step!

Step 3 – Add Cherry and Pineapple

Place 1 maraschino cherry in the bottom center of each jar. Add crushed pineapple around the cherry — just enough to cover the bottom of the jar (about 1-2 tablespoons per jar).

Step 4 – Make the Brown Sugar Syrup

In a small saucepan, combine 1 cup pineapple juice (from the can) and 1 cup brown sugar (or less to taste). Heat to a good boil, stirring until sugar dissolves. Remove from heat.

Step 5 – Pour Syrup Over Pineapple

Pour the hot brown sugar syrup over the pineapple in each jar — enough to cover the fruit (about 2-3 tablespoons per jar).

Step 6 – Prepare Cake Batter

Prepare the pineapple upside down cake mix according to package directions. Use the remaining pineapple juice (plus water if needed) as the liquid.

Step 7 – Add Batter to Jars

Pour cake batter into each jar, filling halfway (about halfway up the jar). The cake will rise during baking, so don't overfill.

Step 8 – Bake

Place jars on a rimmed baking sheet (no lids on during baking). Bake at 350°F (175°C) for 30 minutes, or until a toothpick inserted into the cake comes out clean.

Step 9 – Cool and Seal

Remove jars from oven (use oven mitts — jars are extremely hot!). Let cool on a wire rack for 10-15 minutes. If you plan to give them as gifts or store them, add sterilized lids and rings while still warm — they will seal as they cool.

🍍 To serve: Run a knife around the edge of the jar, place a plate on top, and flip! The pineapple and cherry will be on top — a perfect upside-down cake.

🎄 Holiday tip: These make incredible Christmas gifts! They're shelf-stable for weeks and everyone loves a homemade cake in a jar.

✨ Pro Tips for Perfect Cake-in-a-Jar

• Use wide-mouth jars only: Regular mouth jars are too narrow to flip the cake out easily.
• Don't overfill with batter: Fill only halfway — the cake will rise significantly.
• Place jars on a baking sheet: This catches any potential overflow and makes them easier to handle.
• Let cool completely before sealing: If you want a vacuum seal, add lids while still warm.
• Experiment with fruit: Try peaches, mangoes, or apple slices instead of pineapple!

❓ Frequently Asked Questions

Yes, Ball, Kerr, and most name-brand mason jars are oven-safe up to 400°F. Avoid using off-brand or decorative jars — check for "oven-safe" on the packaging. Never put cold jars directly into a hot oven (let them come to room temperature first).

If you seal the jars while warm (creating a vacuum seal), they can last 2-3 weeks at room temperature or up to 3 months in the refrigerator. For longer storage, freeze for up to 6 months.

Absolutely! Use your favorite vanilla, butter, or yellow cake recipe. Fill jars halfway and bake at 350°F until a toothpick comes out clean (usually 25-35 minutes).

You may have forgotten the butter spray, or didn't spray enough. Next time, spray generously — especially the bottom corners. Let the cake cool for 10-15 minutes before flipping, and run a knife around the edge first.

Yes, but you'll need to add liquid — use ½ cup pineapple juice (store-bought) or orange juice. Fresh pineapple also contains bromelain (an enzyme) which can affect texture, so canned is actually recommended for consistent results.
