Preheat your oven to 180ºF. While that warms up, grab a standard-size rimmed baking sheet and line it with parchment paper. This will ensure the fruit leather doesn’t stick and makes for easier removal.

In a food processor or high-speed blender, combine the strawberries, bananas, lemon juice, maple syrup, sea salt, and vanilla extract. Blend until the mixture is silky smooth and there's no fruit chunk in sight! Taste it at this point—if you want to make it sweeter, feel free to add a bit more maple syrup.

Pour the luscious fruit mixture onto the prepared baking sheet. Using a spatula, spread it evenly across the surface, making sure it reaches the corners. To ensure an even thickness, lift the baking sheet slightly and give it a gentle tap on your countertop. Aim for about 1/4 inch thick; too thick and it’ll take longer to dry!

Place your baking sheet in the oven and let it bake for about 6-8 hours. Yes, I said hours! The key here is low and slow; you want it to dry out gradually. Check on it occasionally. The fruit leather is ready when it peels away easily from the parchment paper and feels firm throughout — no soft spots!

Once done, allow the fruit leather to cool. Use scissors to cut it into 12 strips or any shape you fancy. Store these delightful treats in an airtight container in the refrigerator. They should last for about 2-4 weeks, but I doubt they will last that long!
