- 1 1/3 cup applesauce (unsweetened)
- 2 eggs
- 2 teaspoons vanilla extract
- 2/3 cup flour (oat flour or all-purpose flour)

- Optional: 1 cup chocolate chips and/or nuts
Instructions
- Step 1: Preheat the oven to 350ºF and grease a 9×13 inch baking pan.
- Step 2: In a large bowl, mix the grated zucchini, brown sugar, applesauce, eggs, and vanilla until well combined.
- Step 3: In a separate bowl, stir together the flour, cocoa powder, baking soda, baking powder, cinnamon, and salt.
- Step 4: Add the dry ingredients to the wet ingredients and gently stir until just combined. Avoid overmixing.
- Step 5: Fold in the chocolate chips and/or nuts if using.
- Step 6: Pour the batter into the prepared pan and bake for about 55 minutes, or until a toothpick inserted near the center comes out mostly clean.
- Step 7: Allow the brownies to cool before frosting if desired.
Tips & Variations
- Try using all-purpose flour if oat flour is unavailable; both work well.
- Add 1 cup of chocolate chips or chopped nuts for extra texture and flavor.
- Frost with a simple melt of 1/2 cup chocolate chips, 1/2 cup butterscotch chips, and 1/2 cup peanut butter, or spread on some Nutella for a rich finish.
- Make sure to squeeze out excess moisture from the grated zucchini to prevent soggy brownies.
Storage
Store the brownies in an airtight container at room temperature for up to 3 days. For longer storage, keep them refrigerated for up to a week or freeze for up to 3 months. Reheat gently in the microwave if desired, but frosting is best added fresh after warming.

FAQs
Can I substitute the zucchini with another vegetable?
Zucchini works best due to its mild flavor and moisture content, but grated carrots can be a good alternative though it may change the texture slightly.
Are these brownies gluten-free?
If you use oat flour certified gluten-free or another gluten-free flour blend, these brownies can be made gluten-free. Otherwise, using regular all-purpose flour will contain gluten.

Ingredients
Brownie Ingredients:
- 2 cups finely grated zucchini (firmly packed)
- 1 cup brown sugar
- 1 1/3 cup unsweetened applesauce
- 2 eggs
- 2 teaspoons vanilla extract
- 2/3 cup oat flour (or all-purpose flour)
- 1 cup cocoa powder
- 2 teaspoons baking soda
- 1 1/2 teaspoons baking powder
- 1/2 teaspoon cinnamon
- 1/2 teaspoon salt
Optional Add-ins:
- 1 cup chocolate chips and/or nuts
Optional Frosting (Melt Together):
- 1/2 cup chocolate chips
- 1/2 cup butterscotch chips
- 1/2 cup peanut butter
- Or spread on Nutella instead
Instructions
- Preheat Oven: Preheat your oven to 350ºF (175ºC) and grease a 9×13 inch baking pan to prevent sticking.
- Mix Wet Ingredients: In a large bowl, combine the finely grated zucchini, brown sugar, unsweetened applesauce, eggs, and vanilla extract. Stir until the mixture is well blended.
- Combine Dry Ingredients: In a separate bowl, mix together oat flour, cocoa powder, baking soda, baking powder, cinnamon, and salt to ensure even distribution of leavening agents and spices.
- Combine Wet and Dry Ingredients: Gradually add the dry ingredient mixture to the wet ingredients, stirring just until combined to avoid overmixing which can toughen the brownies.
- Add Optional Mix-ins: Fold in chocolate chips and/or nuts if you desire some added texture and flavor.
- Bake: Pour the batter into the prepared pan and bake for about 55 minutes, or until a toothpick inserted near the center comes out mostly clean with a few moist crumbs.
- Cool and Frost: Allow the brownies to cool completely in the pan. For optional frosting, melt together chocolate chips, butterscotch chips, and peanut butter, or spread Nutella on top as a delicious alternative. Spread the frosting evenly over the cooled brownies and serve.
Notes
- Firmly packing the zucchini ensures the proper moisture balance in the brownies.
- Using oat flour makes the recipe gluten-free friendly; all-purpose flour works fine if gluten is not a concern.
- For a nut-free version, omit nuts and adjust the frosting accordingly.
- Check the brownies towards the end of the baking time to avoid over-baking and dryness.
- Allow brownies to cool completely before frosting to prevent melting or sliding of the frosting layer.
- Brown sugar adds a slight caramel flavor that complements the cocoa and zucchini.
