Flourless Peanut Butter Zucchini Brownies

4.9 from 36 reviews

These healthy Flourless Peanut Butter Zucchini Brownies are gooey, decadent, and perfectly sweet–made with 1 bowl and 7 ingredients! They’re free of refined sugar, flour, butter, and oil. Great for those that follow a gluten-free or vegan diet and adored by those that don’t!




  1. Preheat oven to 350F. Grease an 8x8inch baking dish or loaf pan with cooking spray.
  2. Place all ingredients except chocolate chips in a large bowl. Stir until well combined. Fold in chocolate chips.
  3. Dump mixture into loaf pan and use a spatula to spread evenly in pan (you can also wet your hands and pat it down). Sprinkle top with a handful of chocolate chips, if desired. Bake for 30 minutes.
  4. Allow brownies to completely cool (I like to refrigerate mine overnight in the pan once cool) before slicing.
