How to make Chocolate Zucchini Muffins
These chocolate zucchini muffins are easy to make in a blender (and you can also make them without)! We'll walk through the process step-by-step, and don't forget to watch the video!
Use a Vitamix
This is another recipe that deepens my love for my Vitamix. You can take oatmeal, zucchini and a bunch of other good-for-you ingredients and create muffins that are smooth, slightly sweet, and blissfully chocolatey. Zucchini, where? Zucchini, who? Be sure to check out my Vitamix Buying Guide!
Make Oat Flour
The first step in this chocolate zucchini muffin recipe is to make the oat flour. If you regularly purchase oat flour, then simply use that and skip this step. I always make my own because it costs less and I always have oatmeal on hand.
To do this, simply put oatmeal in the container of your Vitamix (or another high-powered blender) and blend for 15-30 seconds until it resembles flour.
Combine Dry Ingredients
Transfer the oat flour to a medium bowl and combine it with the rest of the dry ingredients and stir to combine. Set aside to add to the recipe later.
Blend Wet Ingredients
Next, blend together the wet ingredients until a homogenous (smooth, uniform throughout) mixture forms. It will be green at this point because you haven't added the cocoa powder yet. You can also use a food processor.
If you don't have a blender/food processor
Mash the bananas, add all the rest of the wet ingredients except for the zucchini. Then proceed with the rest of the recipe, and add the zucchini in at the very end after all the rest of the ingredients have been mixed together by hand.
Add vanilla & sugar
Place the vanilla and sugar into the blending container and blend until the sugar is dissolved.
Add dry ingredients
Next, add the dry ingredients to the blender and blend until the mixture is smooth.
Add chocolate chips
One the mixture is smooth, add the chocolate chips and stir by hand.
Pour into muffin pan & bake
Next, scoop about ¼ cup of the prepared batter into each well of a greased muffin tin. Bake until the muffins are set and spring back when touched, and a cake tester inserted in the center comes out clean. You can use muffin liners if you prefer.
Remove and cool
Release & remove the chocolate zucchini muffins from the muffin pan and transfer them to a wire rack to cool before eating.
Serve!
Serve these zucchini chocolate chip muffins with your favorite fruit for a delicious breakfast! Here are some suggestions of spreads that taste great on top of these muffins!
- Homemade peanut butter tastes amazing on these healthy chocolate zucchini muffins.
- Slather on some homemade cinnamon honey butter.
- A dollop of this homemade vanilla almond butter tastes amazing!
Chocolate Zucchini Muffins: Ingredients & Substitutions
- Old-Fashioned oats. You can substitute oat flour (in a 1:1 ratio, so in this recipe 1 ½ cups) for the old-fashioned oats. You can also use solely all-purpose flour or gluten-free all-purpose flour.
- All-purpose flour. 1:1 gluten-free baking flour can be substituted to make these chocolate zucchini muffins gluten-free. You can also use all oat flour, but just know the muffin texture won't be as tall and fluffy. Whole wheat pastry flour is another great substitution for all-purpose flour too.
- Greek yogurt. Any plain or vanilla Greek yogurt will work well in this recipe. To make these chocolate zucchini muffins dairy-free, simply use a dairy-free Greek yogurt.
- Granulated sugar. Any granulated sugar works well in this recipe, including brown sugar or coconut sugar for a refined-sugar free option.
- Honey. maple syrup can be used in place of honey.
