Method
Make the crust
- Heat the oven to 350°F.
- Grease a 9x13-inch metal baking pan and line it with parchment paper, leaving an overhang on the long sides.
- Mix the flour, sugar, and kosher salt in a large bowl.
- Work in the softened butter until the mixture forms an even, crumbly dough.
- Press the dough firmly and evenly into the prepared pan.
- Bake for 18 to 22 minutes, until the edges are lightly golden.
Make the apple filling
- Toss the apples with the lemon juice, sugar, flour, cinnamon, and kosher salt until evenly coated.
Make the crisp topping
- Stir the flour, oats, brown sugar, and cinnamon together.
- Mix in the melted butter until clumps form.
Assemble and bake
- Spread the apple mixture evenly over the warm crust.
- Scatter the crisp topping over the apples.
- Bake at 350°F for 45 to 55 minutes, until the topping is golden brown and the apples are very tender when pierced with a knife.
Finish the bars
- Cool completely in the pan on a wire rack, at least 2 hours.
- Lift the bars out using the parchment and cut into 16 bars.
- Warm the caramel sauce in the microwave for 10 to 15 seconds.
- Stir in the flaky sea salt and drizzle over the bars.
Notes
For clean cuts, let the bars cool completely before slicing. Store covered in the refrigerator for up to 5 days; freeze well-wrapped bars for up to 3 months. For a gluten-free option, use a 1:1 gluten-free flour blend and certified gluten-free oats.
