📝 Step-by-Step Instructions
Step 1 – Prepare the Jars

- Grease the inside of each jar with butter or cooking spray.
Step 2 – Make the Batter
- In a large bowl, mash the bananas.

- In a separate bowl, combine flour, sugar, baking soda, and salt.
- Add dry ingredients to wet ingredients and mix until just combined.
- Fold in walnuts if using.
💡 Pro tip: "Don't overmix the batter – it will make the bread tough."
Step 3 – Fill Jars
- Fill each jar about halfway with batter.
- The bread needs room to rise.
Step 4 – Bake
- Preheat oven to 325°F (165°C).
- Place jars on a baking sheet.
- Bake for 30-35 minutes, or until a toothpick comes out clean.
Step 5 – Seal and Process
- Remove jars from the oven.
- Wipe rims clean.
- Apply lids and bands – fingertip-tight.
- Place jars in a boiling water bath.
- Process for 10 minutes (adjust for altitude).
⚠️ Important: "The sealing process is what makes these jarred breads shelf-stable."
Step 6 – Cool and Check Seals
- Remove jars from the water bath.
- Cool for 12-24 hours.
