Big Crumb Pie Bars

1. Preparation of the Base

Preheat your oven to 375°F (190°C), prepare an 8-by-8-inch baking pan with nonstick spray and parchment paper. Whisk together melted butter, light-brown sugar, granulated sugar, and kosher salt. Add the egg and whisk again. Stir in baking powder and all-purpose flour to form big, coarse crumbs. Press two-thirds into the baking pan and bake for 15 to 17 minutes until lightly golden.

2. Prepare the Fruit Filling

Combine diced mixed fruits, lemon juice, granulated sugar for the filling, ground ginger, and tapioca flour. Toss until well-coated.

3. Assemble and Bake

Spread the fruit mixture evenly over the baked base. Sprinkle the remaining crumb mixture on top. Bake for 40 to 45 minutes until the top is golden brown and fruit juices are bubbling.

4. Cool and Serve

Allow the bars to cool completely. Lift out using the parchment paper, slice into squares, and dust with confectioners’ sugar if desired.
