These jackfruit cupcakes are from Joelen's Culinary Adventures, where you can get the recipe.
As for the flavor, it reminds me a little of mango, apricot and pineapple, all rolled together. Jackfruit is sweet and is used to flavor lots of baked goods in the Philippines.
The jackfruit pulp my parents gave me was a very thick consistency, similar to jam. I used a little of this pulp with a yellow cake recipe to create my Jackfruit Cupcakes. It has a very light, sweet and subtle flavor and adds a nice color to the cupcake. To decorate, I frosted the cupcakes with a classic cream cheese buttercream frosting and garnished with a sliver of jackfruit on the top.
