Ingredients

  • 1 1/2 cups all-purpose flour
  • 1 1/2 cups rolled oats
  • 3/4 cup packed brown sugar
  • 1/2 tsp baking soda
  • 1/2 tsp salt
  • 3/4 cup butter, melted
  • 3 cups raspberries
  • 1/3 cup granulated sugar
  • 2 tbsp cornstarch
  • 1 tbsp lemon juice

Steps

  1. Heat the oven to 175 C (350 F) and line an 8 inch square pan with parchment.
  2. Stir the flour, oats, brown sugar, baking soda, and salt, then mix in the melted butter.
  3. Press two thirds of the mixture firmly into the pan.
  4. Toss the raspberries with granulated sugar, cornstarch, and lemon juice, then spread over the crust.
  5. Crumble the remaining oat mixture over the berries.
  6. Bake 35 to 38 minutes, until bubbling at the edges. Cool completely before cutting.

Notes

Raspberries are delicate, so fold them gently with the sugar and cornstarch. Chilling makes the bars easier to cut.

Pairing Pack with coffee for a late-summer picnic.
