Best Ever!! A suggestiong...pour the sugar evenly on top after adding the rhubarb and whipping cream. Don't skimp out on the cream. It tastes best with the whipping cream, not half-n-half.

The cake was still warm when I tried it, and I thought it was only OK. I refrigerated the leftovers in a sealed container and tried it again the next day....wow, tastes so much better refrigerated...was moist and flavourful. The cake had wonderful texture and the flavour of the rhubarb was more noticeable.

Fabulous! We loved this easy recipe. We used a gluten-free yellow cake mix, and it worked just fine. Because of a dairy intolerance, we replaced the whipping cream with 2 cups of coconut milk, and that worked absolutely perfectly. We're going to try this same basic recipe with peaches instead of rhubarb -- probably cutting down on the sugar in that instance -- and see if that works.
