These soft fluffy Frosted Zucchini Brownies are a sweet way to use up the extra green veggies from your garden. The cake-like texture of these dark chocolate brownies is so delicious.
No one will ever know they are getting a dose of veggies under all that chocolate. Wink, wink.
Earlier this year I decided to update our back patio with some hanging baskets and a few potted hibiscus plants. I should know better than to bring plants into our home. My thumb is truly black.
So far the plants are alive, but they don’t look as healthy and full as they were that first week. I’m trying to remember to water them without overwatering them. And I’m trying to remember to pull the plants down every couple days, so they get more sunshine.
I also spent hours weeding our front flower bed and planting some flowers in it. My thought was that if it was in the ground it would do better. I mean, it’s Florida everything grows here, right?
Wrong. We have had so much rain in the past month, that one of my plants has actually drowned and died. And a few others are not looking so good.
Since clearly I should keep my black thumb away from growing plants, I’m going to continue to buy the fresh zucchini at the grocery store. I see lots of Chocolate Zucchini Cheesecake Muffins and Frosted Butterscotch Zucchini Bars in our future.
I had a few extra zucchinis on our counter after making another bowl of this BLT Zucchini Salad, so I decided to make more chocolate covered zucchini treats. Let’s face it. If our kids can see the green, they are going to run the other way.
I have no idea why they run from zucchini because they eat salads all the time. Those kids are crazy some days!
My plan was to give this Dark Chocolate Zucchini Cake a fun make over, so I started adjusting the flour and baking soda ratios. I even tried adding an egg and some sour cream to the batter, but it kept ending up really fluffy or gummy.
It turns out that some baking soda is necessary when you add sour cream to your batter. I left it out in the second round of zucchini brownies, and those brownies turned out kind of fudgy but also very gummy too.
That was definitely not the brownie texture I was looking for, so I made a third batch of dark chocolate zucchini brownies with the last zucchini I had.
This third batch ended up being my favorite for flavor and texture. Now keep in mind, these zucchini brownies are still a little light and fluffy, and have a cake-like brownie texture to them because of the little bit of baking soda and sour cream I used.
If you are looking for rich, fudgy zucchini brownies, don’t worry. I have a recipe I am testing for that too.
Ingredients in Zucchini Brownies:
Butter: Make sure to use real unsalted butter for these brownies. Actually, I use real butter in all my baking. It tastes better and bakes better. Margarine has extra water added to it, so it can affect the baking time and outcome of your recipes.
Sugar: These brownies use a mixture of brown sugar and granulated sugar. I like to mix the two sugars because it can add a little bit more moisture to a recipe when using brown sugar.
Sour Cream: A little bit of sour cream will add some moisture to these brownies giving them a little bit more of a cake-like texture.
Baking Soda: This will mix with the sour cream to provide a chemical reaction in your brownies causing a little bit of a lift and fluffy texture to happen as the brownies bake.
Extracts: I like to use a mixture of vanilla and almond extract when I’m baking chocolate desserts. It’s a personal preference. I happen to love the smell and taste of almond extract. Feel free to use all vanilla if you prefer that better.
Zucchini: Make sure to shred your fresh zucchini using the smallest side of your grater. You want the shreds to be tiny and small. They will release more moisture in the batter this way, and it will be hard to see them once it is baked. Do not squeeze out any of the extra moisture that is in the zucchini pieces.
Dark Cocoa Powder: I use dark cocoa powder in almost every chocolate dessert I make. I love the dark rich taste it gives baked goods. You can use a regular cocoa powder or cacao powder if that is what you have on hand. Just realize your zucchini brownies will not be as dark after they bake.
How to make Frosted Zucchini Brownies:
Mix the melted butter and sugars until it looks kind of like wet sand. Add the sour cream and extracts and mix again.
Stir together all the dry ingredients and slowly add them to the butter mixture. It will be thick.
Add the shredded zucchini and stir until it is mixed in completely. Spread the batter in a baking pan and bake.
Let the brownies cool completely and then spread chocolate frosting on the top. If you do not want to make frosting, go ahead and sprinkle the top with powdered sugar before serving. Either way, the chocolate zucchini brownies will be amazing.
Pro Tip: Heat a brownie up in the microwave for 10-15 seconds. Trust me, you will love how rich and fudgy these brownies are when warm.
