How to Make It
Heat oven to 375° F. Line the bottom and sides of an 8-inch square baking pan with aluminum foil; butter the foil.
Make the filling: In a small saucepan, combine the figs, brown sugar, orange zest, and ½ cup water. Cook over medium heat, stirring occasionally, until the figs are tender and most of the liquid has been absorbed, 12 to 14 minutes. Remove and discard the zest.
Transfer the fig mixture to a food processor, add the orange juice and salt, and process until smooth. Transfer to a medium bowl and let cool to room temperature.
Make the crust and topping: In a second medium bowl, whisk together the flour, sugar, baking powder, cinnamon, and salt. Using a fork or a pastry cutter, mix in the butter and egg until a crumbly mixture forms.
Make the bars: Transfer half the flour mixture into the prepared pan, pat down evenly, and spread the filling over it. Crumble the remaining flour mixture on top, leaving large clumps. Bake until pale golden, 55 to 60 minutes; let cool completely on a wire rack. Lift the bars out of the pan, using the foil to help, and cut into 16 2-inch bars.
Storage suggestion: Keep the fig bars at room temperature, between sheets of wax paper in an airtight container, for up to 5 days.
