Preheat oven to 150 degrees F or the lowest temperature your oven will go. Line a 11 x 17 baking sheet with a Silpat baking mat. Set aside.

Puree the peaches and sweetener of your choice in a blender or food processor until smooth. Pour fruit mixture onto prepared baking sheet and spread to about a 1/8″ thick. I always pound the baking sheet on the counter a few times to make sure the fruit mixture is evenly distributed.

Place baking sheet in the oven and bake for 6-8 hours, until pan is set and the center is not tacky. Remove from oven and let cool to room temperature. Gently peel off the fruit leather from the Silpat. Cut into squares or strips using a pizza cutter, knife, or scissors. If you want to make fruit roll-ups, roll the strips in parchment paper. Store in an air-tight container.

Note-if you don't have a Silpat baking mat, you can line the baking sheet with plastic wrap or parchment paper. The plastic wrap will not melt in the oven because the temperature is so low. I prefer to use a Silpat though. Get creative and use your favorite fruits, you can also mix fruits! The fruit leather will keep up to a month in an air-tight container.
