I baked a cake. A yellow vanilla cake. Then i pureed blackberries, and added sugar water and cornstarch to make something like blackberry jelly. Then, I put a thick layer of the blackberry puree in-between the cake layers. I also folded some of the puree into the cream i whipped. It made a lavender colored cake, which i topped with whole blackberries. It made a light dessert that was not overly sweet. Yummy.
