What you will need

This recipe uses 7 simple ingredients that you can find at any grocery store:

  • 1.5 cup all purpose flour
  • 1.5 cup old fashioned rolled oats
  • 0.5 cup packed light brown sugar
  • 0.5 cup unsalted butter melted
  • 0.25 teaspoon baking soda
  • 0.25 teaspoon salt
  • 1 cup raspberry jam or preserves

Step by step instructions

Step 1: Preheat and Make the Crumble

Preheat oven to 350 degrees F. In a large bowl stir together the flour oats brown sugar baking soda and salt. Pour in the melted butter and mix until the mixture forms moist clumps that hold together when pressed.

Step 2: Press the Bottom Crust

Reserve about one third of the oat crumble mixture for the topping. Press the remaining two thirds firmly into the bottom of a parchment lined 8x8 inch baking pan to form an even base layer.

Step 3: Add the Raspberry Filling

Spoon the raspberry jam evenly over the pressed oat crust and spread it with a spatula to within a quarter inch of the edges. Leaving a small border prevents the jam from burning against the hot pan sides.

Step 4: Add Topping and Bake

Crumble the reserved oat mixture evenly over the raspberry layer pressing very lightly so some pieces remain chunky. Bake for 28 to 32 minutes until the top is golden brown. Cool completely before slicing.

Easy substitutions

Missing an ingredient? Here are some swaps that work perfectly:

  • raspberry jam → strawberry jam blueberry jam or apricot preserves for a different fruit flavor
  • all purpose flour → gluten free oat flour blend for a gluten free version

Common mistakes to avoid

Watch out for these pitfalls that can affect your results:

  • Spreading the jam too close to the edges which causes it to bubble over and burn onto the pan
  • Slicing the bars before they are completely cool which causes the jam filling to run and make the bars messy
