I couldn’t be happier to find rhubarb back in season, oh those little pleasures. I got myself nice big bunch on the Farmer’s market last Saturday and look what happened, Rhubarb Hazelnut Crumb Bars! And they are good, they are really good and pretty wholesome too. Rhubarb and hazelnuts are the stars in this recipe complimented with buckwheat, coconut, oats, cinnamon, cardamom and maple syrup.
I wanted this recipe to be very simple and quick to make, I layered few ingredients to get the right balance of flavours and sweetness, but kept it fairly simple. Even though rhubarb can be a little sour, it doesn’t need to be over sweetened and I kept the sweeteners to a minimum. Do use gluten-free oats where necessary, you could substitute hazelnuts with almonds if you prefer, that combination would be lovely too. Bake the bars slowly so the rhubarb has time to cook and the base is nicely baked. Enjoy:)

I get so excited when I see fresh rhubarb!! Which is now!!! Beautiful bars!
Same me, I’m going to have to get some more on Saturday! Thank you:)
These bars look ah-maz-ing! I LOVE rhubarb!
Thank you Bethany! I just had the last piece, going to have to make some more soon, they are pretty good:)
Great recipes! Do you think I could make these with apples instead of rhubarb? Thank you!
Hi Margot, I think it should work just fine. You could also replace the hazelnuts with almonds if you like even more options. Hope it comes out well:)
