Recipe adapted from: The Way the Cookie Crumbles
2½ cups unbleached all-purpose flour
2/3 cup granulated sugar
½ teaspoon table salt
16 tablespoons unsalted butter (2 sticks) plus 2 tablespoons, cut into ½-inch pieces and softened to cool room temperature
¼ cup packed brown sugar
1 cup rolled oats, old-fashioned
¾ cup rasberry preserves
2-3 cups fresh raspberries (I used 3)
1 tablespoon lemon juice
Preheat oven to 375 degrees. Spray 9x13 pan with nonstick cooking spray.
In bowl of standing mixer fitted with flat beater, mix flour, granulated sugar, and salt at low speed until combined, about 5 seconds. With machine on low, add 16 tablespoons butter one piece at a time; then continue mixing on low until mixture resembles damp sand, 1 to 1½ minutes.
Measure 1 ¼ cups flour mixture into medium bowl and set aside; distribute remaining flour mixture evenly in bottom of prepared baking pan. Using hands or flat-bottomed measuring cup, firmly press mixture into even layer to form bottom crust. Bake until edges begin to brown, 14 to 18 minutes.
While crust is baking, add brown sugar and oats to reserved flour mixture. Work in remaining 2 tablespoons butter.
Combine preserves, raspberries, and lemon juice in small bowl; mash with fork until combined but some berry pieces remain.
Spread filling evenly over hot crust; sprinkle streusel topping evenly over filling (do not press streusel into filling). Return pan to oven and bake until topping is deep golden brown and filling is bubbling, 22 to 25 minutes. Cool to room temperature on wire rack, 1 to 2 hours; remove from baking pan by lifting foil extensions. Using chef’s knife, cut into squares and serve.
