Pioneer Woman Zucchini Brownies Ingredients
For the Brownies:
- 1/2 cup vegetable oil
- 1 cup granulated sugar
- 1 tsp vanilla extract
- 1 cup all-purpose flour
- 1/3 cup unsweetened cocoa powder
- 1 tsp baking soda
- 1/2 tsp salt
- 2 cups finely grated zucchini (about 2 medium)
- 1/2 cup chopped walnuts or chocolate chips (optional)
For the Chocolate Frosting:
- 1/4 cup unsalted butter
- 3 Tbsp unsweetened cocoa powder
- 2 cups powdered sugar
- 1/4 cup milk
- 1/2 tsp vanilla extract

How To Make Pioneer Woman Zucchini Brownies
- Preheat the oven: Set your oven to 350°F (175°C). Grease and line an 8×8-inch or 9×9-inch baking pan with parchment paper.
- Mix the wet ingredients: In a large mixing bowl, whisk together the oil, sugar, and vanilla until smooth.
- Add dry ingredients: In a separate bowl, combine flour, cocoa powder, baking soda, and salt. Add the dry mixture to the wet ingredients and stir until just combined.
- Fold in zucchini: Stir in the grated zucchini. The batter will be thick at first but will loosen as the zucchini releases moisture. Fold in walnuts or chocolate chips if using.
- Bake the brownies: Spread the batter evenly into the prepared pan. Bake for 25–30 minutes, or until the center is set and a toothpick inserted comes out with a few moist crumbs.
- Cool completely: Let the brownies cool completely before adding the frosting.
- Make the frosting: In a small saucepan over low heat, melt the butter and cocoa powder. Remove from heat and whisk in powdered sugar, milk, and vanilla until smooth.
- Frost and serve: Spread the frosting over the cooled brownies. Let it set for 15–20 minutes before slicing into squares.

Recipe Tips
- Can I skip the frosting? Yes, the brownies are rich enough to enjoy without it.
- How to make it extra fudgy: Add a handful of chocolate chips to the batter.
- Do I need to squeeze the zucchini? No, the moisture from the zucchini is essential for the texture.
- Can I use a different pan size? You can use a 9×13-inch pan, but the brownies will be thinner and cook faster.
- How to tell when they’re done: A toothpick should come out with a few moist crumbs, not wet batter.

How To Store Zucchini Brownies
