Ingredients
  

  • 2 cups pitted dates about 12–14 oz / 340–400 g, chopped
  • 1 1/4 cups water
  • 2-3 tablespoons granulated sugar or brown sugar optional, to taste for the filling
  • 1 teaspoon pure vanilla extract for the filling
  • fine sea salt pinch, for the filling
  • 1 1/2 cups old-fashioned rolled oats
  • 1 1/4 cups all-purpose flour
  • 3/4 cup light brown sugar packed
  • 1/2 teaspoon baking soda
  • 1/2 teaspoon fine sea salt for the crumb mixture
  • 1/2 teaspoon ground cinnamon optional but recommended
  • 1 cup unsalted butter melted and slightly cooled (2 sticks / 226 g)
  • 1 teaspoon vanilla extract for the crumb mixture
  • 1/2 cup chopped walnuts or pecans optional add-in for the crumb mixture
  • 2-3 tablespoons shredded unsweetened coconut optional add-in for the crumb mixture
  • 1/2 orange or lemon zest only, optional for the filling

Instructions
 

  • Preheat the oven to 350°F (175°C). Line a 9x9-inch square baking pan with parchment paper, leaving an overhang on two sides. Lightly grease the parchment and exposed sides with butter or cooking spray.
  • Add the chopped dates and 1 1/4 cups water to a small or medium saucepan. Bring to a gentle simmer over medium heat, stirring occasionally. Reduce heat to low and cook for 8–10 minutes, stirring and mashing the dates as they soften, until thick and jammy. Stir in 2–3 tablespoons sugar (if using), 1 teaspoon vanilla, a pinch of salt, and optional citrus zest. Taste and adjust sweetness if needed. Set aside to cool slightly; it will thicken as it cools.
    2 cups pitted dates, 1 1/4 cups water, 2-3 tablespoons granulated sugar or brown sugar, 1 teaspoon pure vanilla extract, fine sea salt, 1/2 orange or lemon
  • In a large bowl, whisk together the rolled oats, flour, brown sugar, baking soda, 1/2 teaspoon salt, and cinnamon until well combined and no big sugar lumps remain. Pour in the melted butter and 1 teaspoon vanilla. Stir until the mixture is evenly moistened and clumpy, like a crumbly cookie dough. If using nuts or coconut, fold them in now. The mixture should hold together in clumps when squeezed.
    1 1/2 cups old-fashioned rolled oats, 1 1/4 cups all-purpose flour, 3/4 cup light brown sugar, 1/2 teaspoon baking soda, 1/2 teaspoon fine sea salt, 1/2 teaspoon ground cinnamon, 1 cup unsalted butter, 1 teaspoon vanilla extract, 1/2 cup chopped walnuts or pecans, 2-3 tablespoons shredded unsweetened coconut
  • Transfer about 2/3 of the crumb mixture to the prepared pan. Press it firmly and evenly into the bottom with your fingers or the bottom of a measuring cup, making sure to reach into the corners. Pack it just enough so it holds together but not so hard that it becomes dense.
  • Gently spoon the warm date filling over the pressed oat crust. Use an offset spatula or the back of a spoon to spread it into an even layer all the way to the edges, taking care not to disturb the base.
  • Sprinkle the remaining 1/3 of the crumb mixture evenly over the date filling. Let it fall in loose clumps and lightly pat it down so it adheres, keeping the top crumbly for a rustic texture.
  • Bake in the preheated oven for 25–30 minutes, until the top is light golden brown and the filling is bubbling slightly around the edges. If your oven runs hot, begin checking at 22–23 minutes to avoid over-browning.
  • Place the pan on a cooling rack and let the bars cool completely, at least 2 hours. For tidier slices, chill the cooled pan in the refrigerator for 30–45 minutes before cutting.
  • Use the parchment overhang to lift the slab out of the pan onto a cutting board. With a sharp knife, cut into 16 larger bars (4x4) or up to 20 smaller squares, wiping the knife between cuts for clean edges. Serve at room temperature, chilled, or slightly warmed, optionally with a scoop of vanilla ice cream.

Notes

Storage: Store at room temperature in an airtight container for 2–3 days, or in the refrigerator for up to 1 week (they get firmer and extra chewy). To freeze, freeze cut bars in a single layer until solid, then transfer to an airtight container or freezer bag for up to 3 months. Thaw at room temperature for 30–60 minutes or in the fridge overnight. Reheat briefly in the microwave (10–15 seconds) or in a 300°F oven for 5–8 minutes.
Variations: Add 1/2–3/4 cup toasted nuts for a nutty crunch, 1/4 cup shredded coconut for coconut-date squares, extra cinnamon and a pinch of nutmeg plus orange zest for citrus spice date bars, or drizzle cooled bars with melted dark chocolate. For gluten-free bars, use certified gluten-free oats and a 1:1 gluten-free baking blend. For lower sugar, reduce the brown sugar in the crust to 1/2 cup and omit the sugar in the filling if your dates are very sweet.
Tips: Let bars cool fully before slicing so the filling sets. Chop dates fairly small for a smoother, jammy filling. Adjust added sugar based on how sweet your dates are. Use parchment with overhang so you can lift the slab out easily. For a firmer crust, press the bottom layer a bit more firmly and bake a few minutes longer; for softer, chewier bars, follow the standard bake time and press more lightly.
