Plum Crumble Bars

Celebrate plum season with these super flavourful crumble bars, with a rich flavour and chewy texture that is to die for. We used a mixture of sifted and whole grain flours here for enhanced taste and texture. 

Plum Crumble Bars
~ adapted from The New York Times
2 ¼ pounds/about 1 kilogram red, black or purple plums, pits removed and roughly chopped (about 6 cups)
1 ½ cups/300 grams plus 1/3 cup/65 grams granulated sugar
¼ cup/30 grams cornstarch
2 teaspoons vanilla extract
3 cups/240 grams of old-fashioned oats
2 ½ cups/320 grams Flourist Sifted Red Spring Wheat Flour
¾ cup/90 grams Flourist Whole Grain Red Spring Wheat Flour
1 ½ cups/330 grams brown sugar
1 teaspoon baking powder
1 teaspoon coarse kosher salt
1 teaspoon ground cinnamon
1 ½ cups/340 grams unsalted butter, melted

In a large pot, combine plums and 1 1/2 cups/300 grams of granulated sugar. Heat over medium-low heat, stirring occasionally, until fruit releases juices and becomes very tender, 12 to 15 minutes. Meanwhile, place a small plate in the refrigerator to chill. You’ll use this later to check the doneness of the jam.

Purée plum mixture in the pot using an immersion blender (be careful of splashing), or remove from pot and purée in a blender or food processor until relatively smooth. Return purée to pot if you removed it, and cook over medium-low heat, stirring occasionally, until mixture thickens and reduces by about half, about 10 minutes. You should end up with about 3 1/2 cups/840 millilitres plum jam. (You can test the doneness by spooning a small amount of the jam onto the chilled plate, returning it to the refrigerator and letting it sit for 2 minutes. It should keep a clean line when you run your finger through it.)

In a small bowl, whisk remaining 1/3 cup/65 grams granulated sugar with cornstarch to combine. Whisk sugar-cornstarch mixture into jam and cook, stirring occasionally, until it simmers. Simmer for 1 minute, stirring well to prevent scorching. Stir in vanilla extract, and cool plum mixture to room temperature.

Heat oven to 350 degrees, and line a 9-by-13-inch pan with parchment paper with an overhang on all sides. In a large bowl, combine oats, flour, whole wheat flour, brown sugar, baking powder, salt, and cinnamon. Add melted butter and stir until the mixture forms streusel-like crumbs.

Press 2/3 of crumb mixture into an even layer at bottom of prepared pan. Spread cooled plum jam in an even layer over crust, then sprinkle remaining crumb mixture evenly over top of jam. Bake until jam bubbles at edges and streusel is lightly browned, 45 to 55 minutes. Cool completely before slicing into 12 pieces.
