Flourless Rhubarb-Almond Upside-Down Cake
Our naturally gluten-free cake swaps ground almonds for all the flour and wears a rosy blanket of tart rhubarb and chopped nuts.
Recipe Summary test
In testing this recipe, we found that frozen rhubarb or fresh supermarket rhubarb often yielded a prettier cake than backyard rhubarb, which tends to be more green in color. But all are delicious.
