Preheat oven to 375F. In a large mixing bowl whisk together dry ingredients
1 ½ cups all-purpose flour, ½ cup cocoa powder, ½ cup white sugar, ¾ teaspoon baking powder, 1 teaspoon baking soda, ¼ teaspoon salt
In a separate bowl whisk together wet ingredients.
1 flax egg, 1 cup non-dairy milk, ⅓ cup strongly brewed coffee or espresso, 1 stick melted vegan butter, ¼ cup maple syrup, 1 teaspoon vanilla extract
Add wet ingredients to dry and stir until combined. Fold in chocolate chips or chocolate chunks.
½ cup chopped dark chocolate chunks or dark chocolate chips
Grease your muffin tin using cooking spray (make sure to get muffin pan cavities so it doesn't stick!) OR use paper liners. Pour chocolate espresso muffin batter into pan filling it about ½ way. Sprinkle more chocolate chips on tops of muffin batter (if desired). Bake for 15-20 minutes or until a toothpick inserted into the center of the muffins comes out clean.
Let them cool for 1 minute before removing from the pan and letting cool on a wire rack.
