Rhubarb Crumb Cake

Rhubarb Crumb Cake

This delicious Rhubarb Crumb Cake is a lovely moist and light rhubarb coffee cake, topped with a crunchy crumb topping!

My rhubarb has just now poked out of the ground, but thankfully, I had one last bag of last year’s rhubarb in my freezer that needed using up. And I have to say, there’s almost no better use of it that this cake!

This is a great snacking cake and it keeps really well! We were still grabbing pieces of this cake 5 days out and it was just as good as the first day.

You can start with fresh rhubarb or frozen. If using frozen, you don’t need to thaw it before using in this cake.

Cook’s Notes for Rhubarb Crumb Cake




This cake is perfect for baking ahead, as it stays moist really well (covered at room temperature). It also freezes well!

Of course, if you can’t get hold of (or don’t like) rhubarb, you can swap out just about any fruit (fresh or frozen) for the rhubarb.
