Preheat your oven to 350 degrees f.
Shred zucchini skin-ON, with a cheese grater, then squeeze in a paper towel to draw out excess moisture.
Alternatively, you can use a food processor. I used about one and a half cups (after moisture was patted out, and lightly packed) shredded zucchini, but a bit more or less is totally fine in the recipe.
In a large bowl, mash your banana using a fork, then stir in almond/peanut butter, honey, coconut oil, eggs, creme cheese and vanilla.
Whisk to combine.
Stir in the dry ingredients, then gently fold in blueberries.
Lightly spray, or wipe with coconut oil, OR use silicone liners; a 12 cup muffin pan, and divide the batter evenly between those cups.
Bake in your preheated oven for 22 minutes or until a toothpick inserted in the middle of the muffin comes out clean.
