Raspberry Streusel Bars

Ingredients

2 ½ cups (12 ½ ounces/354 grams) unbleached all-purpose flour ⅔ cup (4 ⅔ ounces/132 grams) granulated sugar ½ teaspoon table salt 18 tablespoons (2¼ sticks) unsalted butter , cut into 18 pieces and softened to cool room temperature½ cup (1 ½ ounces/43 grams) old-fashioned rolled oats ½ cup pecans , toasted and chopped fine¼ cup packed (1 ¾ ounce/50 grams) packed light brown sugar ¾ cup raspberry jam 3 ¼ ounces (92 grams/¾ cup) fresh raspberries 1 tablespoon lemon juice

Before You Begin

This recipe can be made in a standing mixer or a food processor. Frozen raspberries can be substituted for fresh; be sure to defrost them before combining with the raspberry preserves. If your fresh raspberries are very tart, add only 1 or 2 teaspoons of lemon juice to the filling. The bars are best eaten the day they are baked but can be kept in an airtight container for up to 3 days (the crust and streusel will soften slightly with storage).

Instructions

  1. Adjust oven rack to middle position and heat oven to 375 degrees. Make foil sling for 13 by 9-inch baking pan by folding 2 long sheets of aluminum foil; first sheet should be 13 inches wide and second sheet should be 9 inches wide. Lay sheets of foil in pan perpendicular to each other, with extra foil hanging over edges of pan. Push foil into corners and up sides of pan, smoothing foil flush to pan. Grease foil.
  2. Whisk flour, granulated sugar, and salt together in bowl of stand mixer. Fit mixer with paddle and beat in 16 tablespoons butter, 1 piece at a time, on medium-low speed until mixture resembles damp sand, 1 to 1½ minutes. Set aside 1¼ cups mixture in bowl for topping.
  3. Sprinkle remaining flour mixture into prepared pan and press firmly into even layer. Bake until edges of crust begin to brown, 14 to 18 minutes, rotating pan halfway through baking. (Crust must still be hot when filling is added.)
  4. Meanwhile, stir oats, pecans, and brown sugar into reserved topping mixture. Add remaining 2 tablespoons butter and pinch mixture between your fingers into clumps of streusel. Using fork, mash jam, raspberries, and lemon juice in small bowl until few berry pieces remain.
  5. Spread berry mixture evenly over hot crust, then sprinkle with streusel. Bake until filling is bubbling and topping is deep golden brown, 22 to 25 minutes, rotating pan halfway through baking.
  6. Let bars cool completely in pan on wire rack, about 2 hours. Using foil overhang, remove bars from pan. Cut into 24 pieces before serving. (Uncut bars can be frozen for up to 1 month; let wrapped bars thaw at room temperature for 4 hours before serving.)

Why This Recipe Works

We realized early in developing our raspberry streusel bar recipe that the bottom crust needs to be firm and sturdy, while the topping should be light as well as sandy and dry so it can adhere to the filling. Since we didn't want to make two separate mixtures for the top and bottom layers, we used a butter-rich shortbread for the bottom crust and then rubbed even more butter into the same dough to produce a great streusel topping. The filling for our raspberry streusel bar recipe also needed complementary textures: Good raspberry preserves made the filling sweet and viscous, while fresh raspberries—lightly mashed for easier spreading—combined with the preserves to produce a bright, well-rounded flavor and perfectly moist consistency.

Before You Begin

This recipe can be made in a standing mixer or a food processor. Frozen raspberries can be substituted for fresh; be sure to defrost them before combining with the raspberry preserves. If your fresh raspberries are very tart, add only 1 or 2 teaspoons of lemon juice to the filling. The bars are best eaten the day they are baked but can be kept in an airtight container for up to 3 days (the crust and streusel will soften slightly with storage).
