Tips for the Best Rhubarb Crumble Bars

Use finely chopped rhubarb so the jam cooks down quickly and evenly. If your rhubarb is especially tart, adjust the maple syrup in the jam layer slightly.

Press the crust layer firmly into the pan so it holds together when slicing. Chill the bars before cutting for the cleanest slices—and store leftovers in the fridge to keep the layers set.
