Preheat the oven to 350° F. Line 18 muffin tins with paper liners.Lay a clean towel on the counter and spread the zucchini out in an even layer, sprinkle with 1/2 teaspoon salt, cover with another towel, and let sit 5 minutes, then squeeze out any excess water. You should have 1 cup of zucchini. In a bowl, stir together the mashed bananas, coconut oil, honey, eggs, and vanilla until combined. Mix in the squeezed-out zucchini. Add the flour, baking soda, cinnamon, and salt, mix until just combined. Fold in the chocolate chips. Divide the batter among the prepared pans. Bake for 20-22 minutes or until a toothpick inserted into the center comes out clean.Meanwhile, make the cinnamon butter. In a small bowl, combine the butter, honey, and cinnamon. Serve the muffins warm or at room temperature smeared with cinnamon honey butter. Enjoy!
