Hawaiian Mochi Butter Cake with Langka-Jackfruit and Mangoes

This is everyone's favorite cake. It's a Hawaiian Mochi Butter Cake with Langka-Jackfruit and Mangoes. Inspired by my basic recipe for Hawaiian Mochi Butter cake, I added slices of tropical fruits: sweet langka (jackfruit) and fresh, ripe mangoes. I used sweet rice flour and bottled langka in syrup for this recipe. And I couldn't let mango season go by without adding its lusciousness to this cake. When enjoying this thick, dense cake, Filipinos will be reminded of similarities to Philippine delicacies like bibingka, cassava cake, tikoy and espasol. This was inspired by a recipe from Food 52. Serves 6 to 8.

Cook's comments:

  • I used bottled langka in syrup for this recipe which I purchased at Asian groceries. Langka (jackfruit) in syrup, bottled or canned can also be bought online.
    Keep this cake covered and refrigerated at all times.
