Sneaky Zucchini Brownies

These Sneaky Zucchini Brownies are rich, chocolatey, and so fudgy, you’d never guess they’re packed with zucchini. The grated or pureed zucchini blends right into the batter, adding incredible moisture without affecting the flavor. They’re a clever way to sneak in some veggies while still enjoying a decadent dessert.

You can enjoy them plain for a lighter treat, dust them with powdered sugar, or take them to the next level with a silky chocolate frosting.
