Soft, jammy fig filling sandwiched between a buttery oat crust and crumble topping. These easy fig bars bake up golden and slice neatly for lunchboxes, coffee breaks, or dessert.
Preheat oven to 350°F. Line an 8-inch square baking pan with parchment, leaving overhang on two sides for easy lifting.
Make the fig filling: In a small saucepan, combine chopped figs, orange juice, lemon juice, cinnamon, and a pinch of salt. Bring to a gentle simmer over medium heat and cook, stirring occasionally, until the figs are soft and the mixture is thick and jammy, about 8 to 10 minutes.
Remove the pan from heat and stir in the vanilla. Mash the figs with a spoon or potato masher until spreadable. Set aside to cool slightly.
Make the crust and crumble: In a large bowl, whisk together oats, flour, brown sugar, baking powder, and salt. Add melted butter, egg, and vanilla; stir until evenly moistened and crumbly.
Reserve about 1 cup of the crumb mixture for topping. Press the remaining mixture firmly and evenly into the prepared pan to form the crust.
Spread the warm fig filling evenly over the crust. Sprinkle the reserved crumble over the top, followed by walnuts if using.
Bake until the top is lightly golden and the edges are set, about 22 to 28 minutes. Cool completely in the pan on a rack.
Use the parchment overhang to lift the slab out. Slice into 16 bars. Serve or store.
Storage: Keep in an airtight container at room temperature for up to 3 days or refrigerate for up to 1 week. Bars can be frozen for up to 2 months.
Notes
For a slightly tarter filling, add 0.5 tsp lemon zest. Swap orange juice with apple juice or water if preferred. To make dairy-free, use plant-based butter. Gluten-free option: substitute a 1:1 gluten-free baking flour and certified gluten-free oats.
