Preheat the oven to 350 degrees F. Line 12 muffin tins with paper liners.
In a large mixing bowl, stir together the mashed bananas, coconut oil, honey, eggs, and vanilla until combined.
Add the flour, baking soda, cinnamon, ginger, cardamom, all-spice, and salt, mix until just combined.
Fold in the chocolate chunks.
Divide the batter among the prepared muffin cups.
Transfer to the oven and bake for 20-22 minutes or until a toothpick inserted into the center comes out clean.
Meanwhile, make the honey butter. In a small bowl, combine the butter, honey, and salt.
Serve the muffins warm or at room temperature smeared with honey-butter.
