Got summer zucchini and not sure what do to with it? Make these dark chocolate walnut zucchini cupcakes for dessert or afternoon snack. These cupcakes are decadent, moist and chocolate! Can’t go wrong with chocolate paired with zucchini. Walnuts for added crunch and even semi sweet chocolate chips make an addition to this sweet cupcake recipe. Everyone will love this summer favorite.

No need to frost these cupcakes, they are sweet enough however; if you want to frost these cupcakes, try this recipe for Chocolate Cream Cheese Frosting or for a lighter version of chocolate frosting Mocha Whipped Cream Frosting would be a great choice. Once the cupcakes are baked oh… I baked them in a cute tulip shaped parchment paper cup for something different and fun; let them cool before frosting or drizzling if you go that route. The longer the cupcakes set out the richer and more moist they become. They are best eaten a day or two after baking. Store in an air tight container for best results or bake and freeze in zip lock freezer safe bag, take out one or two for supper or snack when needed. Recipe makes 14 standard cupcakes.
Ingredients for Dark Chocolate Zucchini Cupcakes
Zucchini, the long green squash that everyone plants in their gardens because they grow so well. You will need 2 cups shredded, I used my food processor for shredding and one good 8″ zucchini was perfect for getting 2 cups. Cocoa Powder, sugar, vegetable oil ( which helps with the moistness along with the zucchini) eggs, flour, baking soda, baking powder. Salt and vanilla adds more flavor while chocolate chips and chopped walnuts add richness and crunch. Recipe takes a few seconds to put together and they bake 20 minutes. You will also need a 12 cup-cupcake or muffin pan, cupcake liners. PS. No need to spray the cupcake or tulip parchment liners.

How to Make Chocolate Zucchini Cupcakes
Begin shredding the zucchini. I used my food processor grating attachment but you can also use a box grater. Zucchini is very wet, so once you grate it, measure out 2 cups and drain between two sheets of layered paper towels. This will absorb the moisture and your cake batter will not be runny.

Next remove from food processor the grating attachment and add the steel blade in the bowl. Add vegetable oil, vanilla and sugar to the bowl, process a about 3 minutes to blend sugar, add 2 eggs process additional 1 minute. Add zucchini and process 5-7 seconds, you want to do this to shred your zucchini a tiny bit more for bite size pieces.
Remove ingredients from processor bowl. Pour mixture into a large mixing bowl, add flour, cocoa, baking powder, baking sofa and salt to the mixture. With a wooden spoon or rubber spatula combine all ingredients to incorporate, once mixture is well mixed, add chopped walnuts. Stir then add chocolate chips.

Scoop cupcakes with an ice cream scoop and place inside the tulip parchment paper liner or standard cupcake liner. One scoop is all you need as the cupcakes will rise and become beautiful. Bake the cupcakes in a preheated 350°F oven for 20 minutes or until toothpick inserted into the middle of the cupcake comes out clean, melted chocolate chips don’t count in this test, as they are supposed to be melted, you just don’t want batter clinging to your toothpick.
Once baked remove the cupcakes from oven and allow too cool on a wire rack. Remove from cupcake pan when cool to touch. At this point you can frost, wrap and freeze or grab a cup of coffee and have a snack. This is a very easy recipe and delish!
