Place a medium coarse strainer over a large bowl. Pour the contents of two cans of Oregon Fruit Red Tart Cherries into the strainer and let them drain for about 5 minutes.

Pour the drained cherries into a 2 or 3-quart saucepan. Add the sugar, cornstarch, kosher salt, and lemon juice. Stir until the cornstarch is dissolved, then let sit for 5 minutes until there is liquid in the pan.

Heat the pan over medium-high heat, bringing the mixture to a boil, stirring occasionally. Once boiling, reduce the heat to medium and cook for another minute, stirring constantly, until thickened and glossy. Remove from heat and stir in the vanilla extract. Set aside.

Preheat your oven to 350°F.

Brush the sides and bottom of a 9x9-inch square pan with melted butter. Line the pan with parchment paper, leaving overhang on all four sides, and brush the parchment paper with butter, making sure to get the corners.

Melt the butter over low heat. While the butter melts, whisk together the flour, sugar, kosher salt, and baking powder in a large bowl for about 30 seconds.

Pour the melted butter into the flour mixture and combine with a spatula until no white bits remain. Reserve 1 cup of this mixture in a separate bowl, then add the shredded coconut to the reserved mixture and toss together.

Press the remaining crust mixture into the prepared pan, ensuring an even thickness.

Bake the crust for 21-23 minutes until the edges are golden brown.

Remove the crust from the oven, keeping the oven on at 350°F. Spoon the cherry filling over the baked crust and spread evenly with an offset spatula. Sprinkle the reserved crumble mixture over the cherry filling.

Bake for 20-22 minutes until the filling is bubbly at the edges and the topping is a light golden brown. Remove from the oven and place on a wire rack to cool. Run an offset spatula or butter knife along the edges to loosen from the parchment paper.

Allow the bars to cool to room temperature, then refrigerate. Once cold, lift the bars from the pan using the parchment sling and cut into squares.
