Preheat the oven to 350 degrees F (175 degrees C). Grease and flour a standard 12 cup muffin tin or line with cupcake wrappers.
In a medium bowl, whisk together the flour, baking soda, baking powder, cinnamon, and salt. Set aside.
In a separate bowl, cream together the butter and sugar until light and fluffy. Add the eggs one at a time, beating until combined. Stir in the vanilla extract.
Gently stir the dry ingredients into the wet ingredients until just combined. Fold in the zucchini and chocolate chips.
Divide the batter evenly among the prepared muffin tins. Bake for 18-20 minutes, or until a toothpick inserted into the center comes out clean. Allow to cool before serving.
