How to Make these Gluten Free Chocolate Zucchini Muffins
Just like the chocolate zucchini bread recipe I based these muffins off, these muffins are a no brainer!
When it comes to equipment you can keep it minimal with just a couple of mixing bowls and a box grater, or power up with a stand mixer and food processor for mixing and grating.
Either way – this recipe comes together in little time without too much effort. Before long you’ll be biting into one of these moist and tender, double chocolate muffins!
The ingredient list is made up of ingredients you likely already have stocked in your gluten free kitchen. If not, they can usually be found in most major grocery store chains.
- Shredded Zucchini – Adds extra moisture without flavor.
- Use a regular box grater (cheese grater) or food processor with a fitted grating attachment.
- A kitchen scale will help you get the more accurate conversion and measurement for the zucchini.
- As a general rule of thumb for measuring grated zucchini: One loosely-packed and blotted measuring cup of zucchini weighs about 4 oz or 115 grams. This is the amount I use in all my zucchini recipes. While the excess moisture is useful for hydrating the batter, too much can make for soggy muffins.
- Gluten Free All Purpose Flour – Most gluten free all purpose flour blends should work here.
- Unsweetened Cocoa Powder – Needed for the rich chocolate flavor.
- Make sure to use unsweetened cocoa powder and not dutch processed cocoa powder.
- Baking Soda + Baking Powder – Adds lift.
- The baking soda is required to react with the yogurt (more on that below). Gluten free muffins usually need a little extra help though which is why you also need baking powder.
- Xanthan Gum – Needed for binding and retaining moisture.
- If your gluten free flour blend already contains xanthan gum then you don’t need to add more xanthan to the batter.
- The muffins I tested without xanthan fell apart quite easily so I do recommend you include it here.
- Eggs or Flax Eggs – For moisture and binding.
- I tested this with regular chicken eggs and with a flax egg.
- The only noticeable difference is that the vegan zucchini muffins were less domed as they didn’t rise as much.
- Yogurt (dairy free if needed) – Adds protein, moisture and lift (better texture + more rise).
- Yogurt is a Baker’s BFF. Chemically speaking: yogurt is an acid and baking soda is a base. When combined in the oven, the two react and form carbon dioxide bubbles helping baked goods rise up.
- Including yogurt also means you can add less oil to the batter (reduced fat and calories).
A quick summary of the steps required to make these double chocolate chip zucchini muffins:
- Grate the zucchini and set aside to add later.
- Whisk the dry ingredients in a large mixing bowl until combined.
- Mix together the wet ingredients in a medium bowl until well combined.
- Pour the wet ingredients into the large bowl with the dry then combine.
- Stir in the zucchini then add the chocolate chips.
- Spoon the muffin batter into the prepared muffin cups (preferably with muffin liners).
- Bake, cool and enjoy!
These muffins are freezer-friendly!
After baking, allow them to cool completely then wrap individually in freezer-safe bags.
When you’re ready to enjoy, reheat for about 30-45 seconds in the microwave for a quick thaw or leave them in the fridge overnight.
