  • About

The raspberry crumb bar is not technically a breakfast sweet. It’s a bar, and bars (as we are all taught) are generally eaten in the afternoon or after dinner. This bar defies categorization. The crumb oat layers are thin and crisp, and the raspberry filling is gently sweetened, making it the perfect morning pastry. At the same time, it is the kind of bar you might crave as the antidote to an uninspired lunch or as a midnight snack. In short, you can eat this bar any time you please.

Ingredients

For the Crust and Crumb

  • cups all-purpose flour
  • 1 cup firmly packed dark brown sugar
  • cups rolled oats
  • ¾ teaspoon salt ¾ teaspoon baking powder
  • ½ teaspoon baking soda
  • ½ teaspoon cinnamon
  • ¾ cup ( sticks) unsalted butter, cut into 1-inch pieces

For the Raspberry Filling

  • ¼ cup firmly packed dark brown sugar
  • 1 tablespoon grated lemon zest
  • ½ teaspoon cinnamon
  • 2 tablespoons all-purpose flour
  • 1 pound raspberries, fresh or frozen
  • ¼ cup fresh lemon juice
  • 2 tablespoons unsalted butter, melted and cooled

Method

Make the Crust and Crumb

Preheat the oven to 350 degrees F. Butter the bottom and sides of a 9-by-13-Inch glass or light-colored metal baking pan. Put a long piece of parchment paper in the bottom of the pan, letting the parchment extend up the two short sides of the pan and overhang slightly on both ends. (This will make it easy to remove the bars from the pan after they have baked.) Butter the parchment.

Put the flour, brown sugar, oats, salt, baking powder, baking soda, and cinnamon in a food processor. Pulse in short bursts until combined. Add the butter and pulse until loose crumbs form.

Reserve 1 cup of the mixture and set aside. Pour the rest of the mixture into the prepared pan and use your hands or the back of a large wooden spoon to push the crust into an even layer in the bottom of the pan. The crust should touch the sides of the pan. Bake until golden brown, 12 to 15 minutes. Transfer to a wire rack and let the crust cool. Keep the oven on while you make the raspberry filling.

Make the Raspberry Filling

In a medium bowl, whisk the sugar, lemon zest, cinnamon, and flour together.

Add the raspberries, lemon juice, and butter and use your hands to toss gently until the raspberries are evenly coated.

Assemble and Bake the Bars

Spread the raspberry filling evenly on top of the cooled crust. Sprinkle the reserved 1 cup crust mixture evenly on top of the filling.

Bake for 35 to 40 minutes, rotating the pan every 15 minutes, until the top is golden brown and the filling starts to bubble around the edges.

Transfer to a wire rack to cool completely, then cut into squares and serve. The bars can be stored in the refrigerator in an airtight container for up to 2 days.
