I highly recommend it, yes! I have actually tested two versions of this cake. This first one was with raw grated beetroots, and the second (this one) with pre-cooked beets. The difference in the texture was massive! The one made with raw beets was more dense, dry and the taste of beetroot was more present. The top of the cake was lumpy as you could still see pieces of grated beetroot. The second one, made with pureed cooked beets is much much smoother, fudgier and with a much more intense chocolate taste.
