In a mixing bowl, combine masa harina, vegetable broth, melted coconut oil, baking powder, and salt. Mix until a dough forms.

In a food processor, blend the shredded jackfruit, olive oil, onion, garlic, cumin, chili powder, vegetable broth, corn, and bell pepper until well combined.

Spread a portion of the dough onto a corn husk, add a spoonful of the jackfruit filling, and fold the husk over. Repeat with remaining ingredients.

Place the tamales upright in a steamer and steam for about 60 minutes or until the dough is firm.
