Ingredients
 

Main Ingredients

  • 3.1 cup all-purpose flour
  • 1 cup old-fashioned rolled oats
  • 0.9 cup granulated sugar
  • 0.3 cup light brown sugar, packed
  • 1 tsp baking powder
  • 0.5 tsp fine sea salt
  • 0.5 tsp ground cinnamon adds warmth to the crumbs
  • 0.9 cup unsalted butter, cold and cubed
  • 1.5 tsp pure vanilla extract
  • 1.25 cup raspberry preserves seedless if preferred
  • 2 cup fresh raspberries gently dried after rinsing
  • 1.5 tbsp fresh lemon juice
  • 1 tsp lemon zest
  • 1 tbsp cornstarch helps thicken the fruit layer
  • 2 tbsp powdered sugar for dusting after baking

Instructions

Preparation Steps

  • Heat oven to 350°F. Line a 9×13-inch pan with parchment, leaving overhang, and lightly grease.
  • Whisk flour, oats, granulated sugar, brown sugar, baking powder, salt, and cinnamon in a large bowl.
  • Cut in the cold butter with a pastry cutter until sandy, pea-sized crumbs form. Stir in vanilla.
  • Press about two-thirds of the crumb mixture firmly into the prepared pan to form an even base.
  • Combine preserves, raspberries, lemon juice, lemon zest, and cornstarch in a bowl. Gently mash a few berries.
  • Spread the raspberry mixture evenly over the crust.
  • Crumble the remaining dough over the fruit, pinching some pieces into larger clumps.
  • Bake until the top is golden and the filling bubbles at the edges, 33–38 minutes. Cool completely in pan.
  • Lift out using parchment, dust with powdered sugar, and slice into bars.

Notes

Variation: Swap in blackberry or strawberry jam, or add 1/2 cup chopped toasted almonds to the crumble for crunch. Storage: Once cooled, store bars at room temperature for up to 2 days, or refrigerate for 5 days. For clean slices, chill 30 minutes before cutting. Bars freeze well for 2 months; thaw uncovered at room temperature.
