In a medium bowl, whisk together all-purpose flour, granulated sugar, baking powder, and a pinch of salt until thoroughly blended.

Add chilled, cubed unsalted butter to the dry mixture. Using a pastry cutter or your fingertips, blend until the mixture forms coarse crumbs.

Bake crust in the preheated oven for 10 to 12 minutes, or until the edges are set but the center appears pale. Remove from oven and cool slightly.

Distribute the cherry and chocolate mixture evenly over the warm, partially baked crust.

Allow bars to cool completely in the pan on a wire rack. Use parchment overhang to lift out and cut into squares or rectangles.
