Add the berries into a high-speed blender or food processor and blend until smooth.
Remove the seeds and skins from the liquid using a strainer. Press and stir the mixture into the strainer with a spatula to get as much liquid as possible.
Stir the honey and vanilla extract, if using, into the berry mixture until well combined.
Spread the mixture evenly with a spatula over a parchment-lined 9x13 baking sheet.
Bake for 10-12 hours, or until the fruit leather peels away easily from the parchment paper and the center is not gooey.
Allow to cool, then remove from parchment paper, slice into strips, roll, and store at room temperature! For best results, roll each slice with a piece of parchment paper.
Notes
It is really important to use a 9x13 baking sheet for this recipe. Otherwise, the fruit leather will be too thin! If you only have a standard-size cookie sheet, double the recipe.
We used a combination of strawberries, raspberries, and blueberries, but you can use any combination of the fruits as long as it equals 4 cups.
Vanilla extract is optional but adds a nice flavor to this recipe!
Removing the seeds and skins is optional, but it makes the fruit leather much smoother. We recommend it if you or your kids are texture sensitive.
