The Yummiest Brownies

I have never been a huge zucchini lover in savory dishes. But once zucchini baked goods were introduced to me, I was hooked! This zucchini brownie recipe is a game changer, and they will turn even the most skeptical into a zucchini lover… In fact I loved them so much when I built my garden I included zucchini so I could make these with my own zucchini!

  • Zucchini makes the brownies so moist and light.
  • This dessert comes together in less than 15 minutes!
  • The zucchini makes these feel like a guilt-less dessert.
  • These are perfect to make-ahead and everyone will be asking for the recipe!

How to Pick the Perfect Zucchini

Any zucchini will work in this recipe.

When choosing a zucchini pick one that is firm (softness can indicate the fruit is going bad). If picking from the garden, generally you want one that is 8″ long.

Very large zucchinis are typically not as good for cooking as the larger they get, the more watery and flavorless they get. But in this case they are good for baking as you are looking for the moisture from the zucchini. If it’s a very large zucchini you may want to cut it in half and scoop out some of the seeds.

ingredients for zucchini brownies. flour, vanilla, zucchini, oil, cocoa powder, sugar, baking soda, and salt.

Ingredients

These brownies come together with basic pantry ingredients plus a zucchini.

  • all-purpose flour
  • unsweetened cocoa powder
  • baking soda
  • salt
  • white sugar
  • vegetable oil
  • vanilla extract
  • zucchini –  this is the magic ingredient in these brownies. It makes the brownies light but so moist. You do not need to peel the zucchini for this recipe, and do not drain it after you grate it. You can use either the fine or coarse side of the box grater. The fine side will allow the zucchini to mix in more without being noticed, but I do not think its necessary and the coarse side is quicker!

Quick and Easy Frosting Ingredients

This is a fool proof frosting that will evenly cover the brownies and make every bite the best bite of brownies you’ve ever had. 

  • milk
  • sugar
  • butter
  • chocolate chips – use any chocolate chip here. Milk chocolate will be a little sweeter, semi-sweet will balance out the sugar for a less sweet frosting.

You will also need a box grater to grate the zucchini, mixing bowls, measuring spoons, and a 9×13 baking pan. For the frosting it comes together quickly in a small saucepan.
