Ingredients

Oat Crumble - Crust

  • 1 cup all-purpose flour
  • 1 ⅓ cups rolled oats
  • ¾ cup granulated sugar
  • 1 teaspoon cinnamon
  • ¼ teaspoon salt
  • cup unsalted butter melted and cooled completely

Peach Filling

  • 2 ¼ cups peaches peeled and cut into small pieces (4-6 peaches, depending on size)
  • 2 tablespoons granulated sugar
  • ¼ teaspoon salt optional (brings out the flavor more)
  • 2 ½ teaspoons cornstarch
  • 1 teaspoon fresh lemon juice can also use orange juice
  • 1 teaspoon vanilla extract

Instructions

  • Preheat the oven to 350°F. Grease an 8 inch baking pan and line the bottom and sides with parchment paper, leaving some overhang on each side for easy removal after it's baked.

Peach Filling

  • Chop the peaches into small chunks about a ½ inch to 1 inch thick. Larger chunks result in peaches not being cooked through.
  • Mix the peaches with lemon juice and vanilla extract. Next, add in the cornstarch, sugar and salt (optional) and toss together. Set aside.

Oat Crumble - Crust

  • Mix the flour, rolled oats, sugar, cinnamon, and salt well in a medium bowl. Then add the cooled melted butter and stir with a spoon or spatula to mix together. Will resemble crumbles, but will stick together.
  • Place ⅔ of the mixture into the prepared baking pan. Spread and press the mixture evenly using your hands or the bottom of a measuring cup.
  • Next, cover the crust with the peach mixture, spooning out the peaches by leaving most of the juice in the bowl as much as possible. Over excess juice is not needed, so it's better to drain the juice off.
  • Sprinkle the remaining dough over the peaches. Use your fingertips to press to the crumbles down a little so they can stick to peaches.
  • Bake for 35-37 minutes until the top becomes golden brown and the crumbles are crunchy.
  • Let cool at room temperature for almost 1 hour.
  • Keep bars in the fridge for extra 1,5 hours until it is completely cool so you can have nicely cut bars.

Notes

Storing Peach Bars:
Keep peach bars in an airtight container in the fridge for up to 4-5 days or in the freezer for up to 3 months.
