Description

These fudgy zucchini brownies are hands-down the best brownies I have ever eaten - and yes, there is an entire zucchini hiding inside! They are deeply chocolatey, perfectly moist and just sweet enough, all while being vegan, gluten-free and incredibly easy to make.


Ingredients

Units Scale
  • 1 medium zucchini, about 6 ounces
  • 1/2 cup raw creamy almond butter
  • 1/4 cup unsweetened almond milk
  • 3/4 cup pure maple syrup
  • 1 teaspoon pure vanilla extract
  • 1 cup store-bought gluten-free oat flour
  • 1/2 cup unsweetened cocoa powder
  • 1 teaspoon baking powder
  • 1/4 teaspoon fine salt
  • 1/2 cup vegan chocolate chips, plus additional chocolate chips for topping

Instructions

  1. Prep the zucchini. Shred it with the skin on, firmly pack one full cup, then squeeze out as much liquid as you can with a clean kitchen towel. Remember: measure first, squeeze second!
  2. Whisk the wet ingredients. Add the squeezed zucchini to a large mixing bowl along with the almond butter, almond milk, maple syrup, and vanilla. Whisk until well combined.
  3. Add the dry ingredients. Whisk in the oat flour, cocoa powder, baking powder, and salt until fully combined and no dry clumps remain.
  4. Stir in the chocolate chips. Fold in ½ cup of chocolate chips and try not to eat the batter!
  5. Bake. Spread the batter evenly into the pan, sprinkle extra chocolate chips over the top, and bake at 325°F for 20 minutes, until a knife comes out without batter on it.
  6. Cool completely (do not skip!). Let the brownies cool fully in the pan, then chill in the freezer before slicing. More on this below because it's THAT important!

Notes

  • Measure the zucchini before squeezing: pack 1 full cup of shredded zucchini, then squeeze out the moisture. Do not skip either step!
  • Use store-bought oat flour rather than homemade. Store-bought oat flour is more finely and evenly ground, which yields the best brownie texture. Make sure it's certified gluten-free if needed. (delete after adding to recipe card
  • A note on baking pans. I have only tested these brownies in my ceramic-coated nonstick square baking pan at 325°F for 20 minutes. If your pan is not nonstick, I would suggest lining it with unbleached parchment paper - but since I haven't personally tested other pans, please keep an eye on your brownies and let me know how it goes! I do not recommend using a glass baking dish as it conducts heat differently and results will vary. 
  • Shred and freeze zucchini during zucchini season. This is my favorite trick for making these year-round! Shred your zucchini while it's abundant in summer, freeze it, and you'll be ready for brownies (and more zucchini recipes) any month of the year.
  • Store the brownies in an airtight container in the refrigerator for up to five days or in the freezer for up to three months.
  • To make these nut-free, replace the almond butter with a seed butter and use an unsweetened nut-free non-dairy milk, such as oat milk. I have only tested the recipe with raw creamy almond butter and almond milk, so the flavor and texture may vary slightly with substitutions.
