Wholesome Ingredients for Fudgy Vegan Brownies
Each ingredient in these healthy vegan brownies is carefully chosen to maximize nutrition without compromising on taste or texture. Here’s what makes them special:
- Zucchini: This humble vegetable is the star ingredient, lending moisture to the brownie batter without detection. Look for firm, unblemished zucchinis, and be sure to squeeze out excess liquid for the perfect texture.
- Almond flour: A gluten-free alternative that keeps the brownies soft and moist. You can substitute with oat flour for a nut-free version, though it may make them denser.
- Coconut sugar: A low-glycemic sweetener that delivers caramel-like notes without the spike in blood sugar.
- Peanut butter: Adds richness and protein. Opt for a runny, natural peanut butter with no added sugar or oil, or swap with sunflower seed butter for a nut-free option.

Step-by-Step Vegan Zucchini Brownies Instructions
- Preheat your oven to 350°F (180°C). Line a 9×5-inch baking tray with parchment paper and set aside.
- Prepare the flax egg: Mix 1 tablespoon of flaxseed meal with 3 tablespoons of lukewarm water. Let it sit for 15 minutes until it becomes gooey and egg-like.
- Grate the zucchini: Use the fine side of your grater or a food processor. Place grated zucchini into a clean towel and wring out as much moisture as possible until dry. Measure 1 packed cup and place it in a large bowl.
- Mix the wet ingredients: To the zucchini, add peanut butter, prepared flax egg, vanilla, maple syrup, and coconut sugar. Stir until smooth and shiny.
- Incorporate the dry ingredients: Sift in cocoa powder, baking soda, and salt, stirring to combine. Add the melted coconut oil and almond flour. Mix until the batter thickens.
- Pour batter into the lined pan. Smooth the top with a spatula and bake for 30 minutes or until the edges are set and a toothpick inserted in the center comes out with a few moist crumbs.
- Cool for 12 minutes in the pan. Use parchment to lift the brownie onto a wire rack. Chill in the fridge for 30 minutes to enhance the fudgy texture before slicing into squares.
