Ube-Purple Yam Hawaiian Mochi Cake

Ube - Purple Yam Hawaiian Mochi Cake is the basic, favorite mochi cake with the addition of the classic Filipino ube haleya or sweet, purple yam jam. This is easy to bake and is a mix-it-all together kind of cake. The recipe makes a large, thick, dense cake which can be sliced in squares for individual servings. The combined flavors of sweet ube, coconut milk and cream define the richness of this cake which is ideal for desserts, snacks or anytime one craves a sweet treat. This was adapted from the Hawaiian Mochi Butter Cake recipe of my cousin Gina Adea and is an Asian in America recipe. Serves 8.
