❓FAQs

Are Rhubarb Bars supposed to be gooey?

No, the filling should be soft and slightly custardy but not gooey or runny. If they come out too loose, they might be underbaked or the fruit had too much moisture. Make sure to bake until the filling is fully set and let them cool completely before slicing.

Can I use frozen rhubarb in Rhubarb Bars?

Yes, you can use frozen rhubarb. Before adding it to the filling, make sure to thaw it completely and drain any excess liquid. This prevents the filling from becoming too watery or runny during baking. Patting the rhubarb dry with paper towels also helps improve the texture of the bars.

Can I make Rhubarb Bars gluten-free?

Yes, Rhubarb Bars can be made gluten-free by using a 1:1 gluten-free flour blend that includes xanthan gum. This type of blend mimics the structure of regular flour and works well for both the crust and filling.

How do I cut clean bars?

To get neat slices, let the bars cool completely in the pan. For best results, chill them in the fridge for an hour after baking. Use a sharp knife and wipe it clean between each cut to avoid messy edges and preserve the bar shape.

Can I add a crumble topping?

Yes, a crumble topping made with oats, brown sugar, flour, and butter adds a crunchy layer that complements the smooth filling. Sprinkle it over the rhubarb before baking for a rustic twist on the classic bars. It also adds texture and visual appeal.
