When choosing apples for this cake, I like to mix Granny Smith with Gala or Fuji. The cakes can be made either in mini-version (I baked them in brioche-style silicone cups, but muffin cups work fine), or as one round cake. Substitute brown sugar with white sugar if you don’t use brown sugar on Pesach, and omit the thyme and zest if you don’t use peels.
