Ingredients
- All-purpose flour (2 cups)
- Old-fashioned rolled oats (1 cup)
- Light brown sugar, packed (3/4 cup)
- Unsalted butter, cold and cubed (1 cup / 2 sticks)
- Salt (1/2 teaspoon)
- Canned sliced peaches, drained and diced (2 cups)
- Crushed pineapple, well-drained (1/2 cup)
- Cornstarch (1 tablespoon)
Instructions
- Step 1: Preheat the oven to 375°F (190°C). Line a 9×13 inch baking pan with parchment paper, leaving an overhang on the long sides for easy removal.
- Step 2: In a large bowl, whisk together the flour, oats, brown sugar, and salt. Cut in the cold butter using a pastry blender or your fingers until the mixture forms coarse crumbs. Reserve about 1 cup of this crumb mixture for the topping.
- Step 3: Press the remaining crumb mixture firmly and evenly into the bottom of the prepared pan to form the crust. Bake the crust for 10 minutes until lightly set.
- Step 4: While the crust bakes, prepare the filling: Gently combine the diced peaches, well-drained crushed pineapple, and cornstarch in a medium bowl. Pour the fruit mixture evenly over the pre-baked crust.
- Step 5: Sprinkle the reserved 1 cup of crumb mixture over the fruit filling. Return the pan to the oven and bake for 30 to 35 minutes, or until the topping is golden brown and the fruit filling is bubbly.
- Step 6: Allow the bars to cool completely on a wire rack for at least 2 hours before lifting them out of the pan using the parchment paper overhang. Slice into bars and serve.
Notes
- For optimal texture, keep these covered at room temperature for 3-4 days, or chill them in the refrigerator if you plan to save them for up to a week.
- To regain that satisfying crumble texture, briefly warm your leftover bars in a low-heat toaster oven until the topping feels crisp again.
- For the ultimate dessert experience, serve these slightly warm bars alongside a generous scoop of vanilla bean or coconut ice cream.
- Remember that the success of the filling relies entirely on using well-drained crushed pineapple—if there is excess moisture, the bars will not set properly.
