To prepare a zucchini chocolate chip cupcakes recipe, first you need to prepare the zucchini. First, you'll need: Zucchini. You can use any type of zucchini you like, but zucchini is my favorite. The zucchini will make the cupcake moist and fluffy, and the chocolate chips will add texture and crunch. If you don't want to use zucchini, then you can substitute another vegetable, such as sweet potato or sweet peas. ... Sift the flour, baking powder, cocoa, sugar, salt and baking soda into the bowl of your stand mixer and mix on medium speed until the ingredients are well combined. Gradually add the wet ingredients to the dry ingredients, mixing after each addition until they're just combined and no streaks of flour remain. Once the batter is smooth, pour it into cupcake liners and bake for 20 to 25 minutes, or until toothpick inserted in the center comes out clean. Allow to cool for 5 minutes before removing from the pan.
