Preheat oven to 400°F (190°C).

Whisk the flour, baking powder, baking soda, sugar, and salt together in a bowl.

Break the stick of butter into pieces and add to the flour mixture. Use your hands to mix it until it’s the texture of a coarse meal.

Add the plantain tidbits, chocolate chips, oats, and spinach to the mixture and combine with your hands.

Pour the buttermilk into the mix and knead until it forms dough and form it into a ball.

Dust a cutting board with flour and coat a baking sheet with cooking spray.

Cut the dough ball in half and roll each half into rounds, about ¾ inches thick.

Cut the rounds into wedges and place on the baking sheet.

Bake until lightly browned, about 15 minutes. Serve warm.
