1-Make the crumb mixture: Combine oats, flour, salt, baking soda, and brown sugar; cut in cold butter until coarse crumbs. Reserve 1/3 for topping, press remaining into a greased 9×13 pan.

3-Assemble the bars: Spread cooled filling over crust, then sprinkle reserved crumb topping evenly.
4-Bake: Bake at 350°F (175°C) for 30-40 minutes until golden and bubbly, rotating pan halfway.
5-Cool and slice: Cool completely in the pan for 1-2 hours, then cut into 12 squares.

🥄 Use old fashioned oats, not instant, for a chewy, hearty texture that holds up to the filling.
⏳ Let the filling cool for 10 minutes before spreading to prevent a soggy crust.
🔪 Cool bars completely for 1 to 2 hours before slicing to ensure clean, crumble-free cuts.
