Ingredients

How to Make the Coconut Flour Brownies

Note that the complete directions are also in the recipe card below.

  • Preheat oven to 350F (180C). Grease or spray 10 cups of a standard size muffin tin.
  • In a large bowl, stir together the nut butter, syrup, vanilla, and salt until smooth. Stir in the shredded zucchini, cocoa powder, coconut flour and baking soda until well blended. Stir in 4 tablespoons of the chocolate chips.
  • Divide batter evenly between prepared cups, smoothing tops with moist fingertips or the back of a metal spoon dipped in water. Sprinkle tops with remaining chocolate chips.
  • Bake in preheated oven for 24 to 28 minutes until set at edge (center may still look moist; do not overbake).
  • Place the muffin tin on a cooling rack and cool completely before removing the brownies.

Tips for Perfect Brownies

  • The key to making these brownies perfect is to avoid over-baking. That means you will need to pull them out of the oven while the centers still look really moist and somewhat under-baked (the toothpick test does not work here).
  • Do not squeeze liquid out of the shredded zucchini. It helps keep the brownies moist!

The brownies will firm up as they cool, so let them cool completely in the tin before attempting to remove them. During these hot summer months, it’s a good idea to let them chill overnight, too.

A chilly brownie on a hot summer day is mighty fine.

And an extra-sweet bonus? These brownies are really power bars in disguise (more than 6 grams of protein apiece!). So forget the guilt and instead relish every chocolate-y bite!

Would these work with frozen zucchini? I have many bags of frozen zoodles. What adjustments might I need to make to account for the different zucchini texture?

Thank you.

Hi Cynthia! Yes, definitely, your frozen noodles can be repurposed for these brownies (sounds like a great plan to me :)). I added the weight of the zucchini to the recipe. You could chop the noodles (relatively fine, but not a puree) . Do not drain off the liquid from the zucchini, you will want to add that in (similar to using frozen bananas; do not drain after thawing when using in baked goods). You could weight 160 g frozen, let it thaw, chop it up and add, along with all of the defrosted liquid from the 160 grams.

Making now, substituted out maple syrup, for the 1/4 cup of sweetener (Splenda) and two tablespoons of water, but it’s consistency is nothing like maple syrup, it’s just sweet water. Is this correct?

Camilla

Hi Chloe, I am sure that will work (I have never baked with Splenda, though. Is it a Splenda for baking blend?) The substitution options are not meant to be like maple syrup, per se, but what you can use in the recipe instead of maple syrup to get a similar result. I hope that makes sense!
