This is a fantastic cake that I have made it many times and it's one of the best rhubarb cakes! --- and it also will work well with fresh blueberries ;-)

We enjoyed this cake, however we thought that the topping was a little too thick and sweet for the cake. I'll cut the topping ingredients in half the next time I make it. I also cut the pieces smaller so I will probably get at least 24 servings from this cake - lots for lunches. Thanks for posting.

Yummy rhubarb cake - especially when rhubarb is in season. Only change I make is to reduce sugar, but do that with most recipes. For a change of flavor I add some grated orange rind - marries well with rhubarb. Thanks for a great cake Kittencal.

Absolutely my favorite dessert, hands down! My Grandma always made rhubarb cakes, crumbles, crisps, etc and this one tastes just like one of hers! I haven't had one since she passed in '81 and BOY do I miss them! Thank you for posting a MAJOR KEEPER for me!!! I just adore rhubarb! I made exactly as directed with the exception of the nuts - I don't care for them so I omitted them.
