For the crumb crust and topping:

  • 3 cups (375 grams) all-purpose flour (spooned & leveled)
  • 1/2 cup (100 grams) brown sugar
  • 1/2 cup (100 grams) granulated sugar
  • 1 teaspoon baking powder
  • 1 teaspoon ground cinnamon
  • 1/4 teaspoon ground nutmeg
  • 1/4 teaspoon salt
  • 1 cup (230 grams) cold butter , cubed
  • 1 large egg , lightly beaten

For the peach filling:

  • 5 cups (800 grams) chopped peaches
  • 1/2 cup (100 grams) granulated sugar
  • 3 tablespoons (27 grams) cornstarch
  • 2 teaspoons fresh lemon juice
  • 1/2 teaspoon ground cinnamon


For the crumb crust and topping:

  • Preheat oven to 350°F. Line a 9x13-inch pan with parchment paper or aluminum foil, leaving some overhang for easy removal, and set aside.
  • In a large mixing bowl, whisk together the flour, brown sugar, granulated sugar, baking powder, cinnamon, nutmeg, and salt.
  • Add the cold cubed butter and cut it in with a pastry cutter until the mixture is crumbly and starts to come together.
  • Add the egg and stir it in until fully combined (you may also use the pastry cutter to help blend it in).
  • Press half of the mixture in the prepared baking pan and place the bowl with the other half in the refrigerator.
  • Bake the crust at 350°F for 15 minutes, then set aside to cool for 5 minutes before adding the peach filling.

For the peach filling:

  • Combine the chopped peaches, sugar, cornstarch, lemon juice, and cinnamon in a large bowl. Mix until the peaches are fully coated.
  • Spoon the peach filling on top of the baked crust, using a slotted spoon to leave as much excess juice as possible in the bowl. Spread it around into one even layer.
  • Remove the remaining crumb mixture from the refrigerator and sprinkle it on top of the peach filling.
  • Bake at 350°F for 40-50 minutes or until the top is set and lightly browned and the peach filling is bubbling around the edges.
  • Remove from the oven and transfer to a wire rack to cool completely. Once cooled, lift the bars out of the pan using the overhang from the parchment paper or foil, slice into bars, and enjoy!


Storage instructions: Store crumb bars in an airtight container in the refrigerator for up to 3 days.
