  1. With the rhubarb beginning to peak out of it’s mound of earth, this post hit my in box at a perfect time. The recipe looks tremendous and we look forward to making it in a few weeks when the red stalks are ready to eat.


  2. I was also drawn to the chocolate rhubarb combination.
    Made this tonight. Tempted to call the biscuit part a custard, yet as there is no dairy that really doesn’t fit. I think when I repeat I would make the biscuit part immediately before pouring on to the pre-baked portion. My batter seemed to have lost some of its fluff and took about twice as long as 8-10 minutes to solidify. I also added a bit of sea salt to layers 1 and 3.
    Trying it about 15 minutes out of the oven I am inspired by the flavors to try to get it right. Would the first part be better a bit longer or at a slightly higher temp? Say 425F or for 30 minutes or both? I also wonder if the shortbread layer should be a bit thinner.


      1. Oh yes. Cooled it and then put it in the fridge overnight. Yum. The chocolate bottom was almost like fudge when chilled. I need more practice. Thank you.

      2. Dear Ruta,
        Made the cake again and although it is still not as beautiful as yours I think am beginning to get there.
        After re-reading the recipe and looking at the picture and thinking to myself this is like sponge cake, I whipped the eggs and sugar until they began to form waves and a bit longer, and then folded in the flour.
        Then I googled sponge cake and found a site where they called it biskvit and it all came together.
        Wiki to the rescue:
        The rest is oven differences.
        Love the blog.


      3. 🙂 yes. This is the most interesting and the most complecated part of bligging. Different cultures, languages and understandings. In Estonia we use word “biskviit” to describe sponge cake. And it is seems to me right word to use it in English as well 🙂 🙂
