Mixed Berry Oat Bars
Servings: 13 x 9 pan to be cut as you like
Ingredients
- 1 ½ cups whole wheat pastry flour or white whole wheat flour
- 2/3 cup muscovado or packed light brown sugar
- 1 ¼ cups old-fashioned rolled oats
- ¾ teaspoon fine grain sea salt
- ¾ teaspoon aluminum-free baking powder
- ½ teaspoon baking soda
- ½ teaspoon ground cinnamon
- ¾ cup 1 ½ sticks cold unsalted butter, cut into 1-inch pieces
- ½ cup chopped pecans for topping only optional
- Berry Filling:
- 1 Tablespoon grated lemon zest
- ½ teaspoon ground cinnamon
- 2 Tablespoons flour whichever you used in the crust/topping
- 1 pound fresh or frozen blueberries raspberries and/or blackberries, about 3 cups
- 2 Tablespoons freshly squeezed lemon juice
- 2 Tablespoons unsalted butter melted and cooled
Instructions
- Preheat the oven to 350 degrees. Butter the bottom and sides of a 9 x 13-inch baking dish. Line the bottom with unbleached parchment paper (to help remove the bars.)
- Put the flour, sugar, oats, salt, baking powder, baking soda and cinnamon in a food processor. Pulse until combined. Add butter and pulse until crumbs form and the mixture is no longer powdery and dry. Alternatively, place everything in the bowl of a stand mixer and mix on low speed until everything is moistened. Grab a handful of the mixture and squeeze it. It should hold together. Take 1 ½ cups of the mixture, place in a medium bowl and add chopped pecans.
- Pour the rest of the mixture into the prepared pan and use your hands or the back of a metal spatula to press the crust into an even layer on the bottom of the pan. Bake until golden brown, 12-15 minutes. Transfer to a wire rack and cool.
- In a medium bowl, whisk lemon zest, cinnamon and flour together. Add the berries, lemon juice and butter and use your hands to toss gently until the berries are evenly coated.
- Spread filling evenly on top of the cooled crust. Sprinkle the reserved crumble mixture on top of the filling. Bake for 35-45 minutes, until the top is golden brown and the filling starts to bubble around the edges a little. You may need to rotate the pan halfway so that it cooks evenly.
- Transfer to a wire rack to cool completely before cutting into bars. Keep refrigerated for up to two days in an airtight container.
Notes
*To make these gluten-free, substitute gluten-free oat flour or your favorite gluten-free baking mix, as well as gluten-free rolled oats.
Berries are usually not very sweet and these bars are also not overly sweet. If you think your berries are more tart, you can add a couple tablespoons of maple syrup or brown sugar to the fruit mixture.
