how to make Strawberry Oatmeal Crumble Bars

  1. Preheat the oven to 350°F and line an 8-inch square pan with foil. Spray the foil with cooking spray so the bars lift out easily.
  2. Melt the butter in a microwave-safe bowl or on the stove.
  3. Mix the flour, oats, granulated sugar, brown sugar, and salt with the melted butter. Stir until the mix looks sandy with some clumps.
  4. Set aside 1 heaping cup of the mixture for the crumble topping.
  5. Press the remaining mixture firmly into the bottom of the prepared pan to make an even crust.
  6. Toss the chopped strawberries with 1/3 cup sugar, lemon juice, and cornstarch until coated. Spread the strawberry mix over the crust in an even layer.
  7. Sprinkle the reserved crumble mixture evenly over the strawberries.
  8. Bake at 350°F until the top is golden and the filling bubbles at the edges, about 25–35 minutes.
