King Arthur Zucchini Brownies

Now a lot of people say you have to pick zucchinis when they are small because they are more tender or taste better. I think that’s a lot of hogwash to sell less vegetable at a higher price. Big zucchinis are great for zucchini bread, squash casserole, zucchini roll-ups, grilled zucchini, zoodles, and so much more. In fact, I think they make even better zucchini brownies! This is my slight variation of the King Arthur Zucchini Brownie recipe. You can check out their website for the original.

SUPPLIES NEEDED:IMG_20180708_200242268_HDR
Cutting Board
Food processor

1/2 teaspoon Sea Salt
1/2 to 2/3 Cup Whole Wheat Flour
3/4 Cup SemiSweet Chocolate Chips

1/2 Cup Peanut Butter
2 Cups Powdered Sugar plus more as needed

1) Trim the ends from the zucchini and then measure out a 12 ounces piece.

6) Process it all until its a smooth batter.
7) Pour the mixture into the greased baking dish.
8) Bake for about 25 to 30 minutes.
9) As the brownies are cooling its time to make the peanut butter frosting. In a bowl, add the Crisco and peanut butter. Mix it together.
10) Beat in the powdered sugar until its the perfect frosting consistency. You can add a bit of vanilla or milk if desired.
11) Frost the brownies and serve. I like to frost them when they are still a bit warm so it melts a little into the top layer of the brownie.


Incredibly delicious! You would never guess there are 12 ounces of zucchini in this pan of brownies! That’s over an ounce of vegetable per serving of dessert. Not a bad way to keep the guilt away.
