These crispy raspberry crumble bars feature a buttery oat streusel topping with a bright, gooey raspberry jam filling, perfect for a quick and easy homemade dessert.

Ingredients

Scale
  • 1 ½ cups (180g) all-purpose flour
  • 1 ½ cups (135g) old-fashioned rolled oats
  • ¾ cup (150g) granulated sugar
  • ½ teaspoon baking powder
  • ¼ teaspoon salt
  • 1 cup (225g) unsalted butter, melted and slightly cooled
  • 1 teaspoon vanilla extract
  • 1 cup (320g) raspberry jam
  • 1 tablespoon fresh lemon juice
  • 1 teaspoon lemon zest (optional)

Instructions

  1. Preheat your oven to 350°F (175°C). Line a 9×9 inch pan with parchment paper or lightly grease it.
  2. In a large bowl, combine 1 ½ cups flour, 1 ½ cups rolled oats, ¾ cup sugar, ½ teaspoon baking powder, and ¼ teaspoon salt. Stir until evenly distributed.
  3. Pour in 1 cup melted butter and 1 teaspoon vanilla extract. Stir gently until the mixture is crumbly but holds together when pressed.
  4. Press half of the oat mixture firmly into the bottom of the prepared pan to form the crust layer.
  5. In a small bowl, mix 1 cup raspberry jam with 1 tablespoon lemon juice and 1 teaspoon lemon zest.
  6. Spread the jam mixture evenly over the crust layer without pushing it into the crust.
  7. Crumble the remaining oat mixture over the jam layer, sprinkling evenly without pressing down.
  8. Bake the bars for 35-40 minutes until the top is golden brown and crisp.
  9. Cool completely in the pan on a wire rack for at least 2 hours before slicing.
  10. Slice into bars using a sharp knife, wiping the knife between slices. Serve at room temperature or chilled.

Notes

Press the bottom crust firmly but keep the streusel topping loose for crispiness. Use melted, cooled butter for best texture. Let bars cool completely before slicing to avoid a jammy mess. A quick broil for 1-2 minutes can crisp the topping if needed. For gluten-free, use gluten-free flour and oats; for dairy-free, substitute butter with coconut oil.
