Preheat your oven to 350 degrees
Shred a medium zucchini and transfer into a paper towel lined bowl. Set aside for now.
In a large bowl, whisk 1 cup of almond milk with 1/3 cup of honey, 2 large eggs, 4 tablespoons of melted butter, 3 tablespoons of brown sugar and 2 teaspoons of vanilla extract.
In a separate bowl, combine 1 cup of oat flour, 1/4 cup of ground flaxseeds, 1/4 cup of natural unsweetened cocoa powder, 1 teaspoon of espresso powder, 1 teaspoon of baking powder, 1/2 teaspoon of baking soda and 1/2 teaspoon of salt and add this mixture to the almond milk mixture.
Use the paper towels to squeeze any excess moisture from the shredded zucchini and add it into the batter along with 3/4 cup of dark chocolate chips or chunks. Mix until fully combined.
Line a standard cupcake tin and fill each cavity almost full.
Bake the muffins in a 350 degree oven for 18-22 minutes or until they feel lightly set and the tops no longer look wet. Do not overbake as they will continue to set as they cool.
Enjoy these muffins warm or at room temperature. Store leftovers in an airtight container for up to 3 days.
