Recipe Ingredients

These oatmeal zucchini muffins are without a doubt a favorite snack. I’ve made them so many times – I’m obsessed! All we need is some ingredients from our healthy baking pantry and fresh zucchini, of course:

• quick oats + oat flour – If you already have oat flour on hand, you can use that. Otherwise simply pulse some quick oats into flour (more on this below). You’ll need both quick oats AND oat flour for this recipe. Use certified gluten free oats, if needed. Note: If you want to sub the oat flour, you can likely use wheat flour or white whole wheat flour, but I did not test it this way.
• baking soda – the leavening agent to make the muffins rise.
• cinnamon – taste testers preferred one full teaspoon here. If you don’t love cinnamon, use 1/2 teaspoon ground cinnamon.
• fine sea salt – to help balance the flavors.
• pure maple syrup – naturally sweetened without refined sugar. You can also use honey if you’d like.
• light olive oil – or avocado oil, or melted coconut oil (room temperature). Basically any mild oil will work.
• egg + egg white – I found using one large egg plus an additional egg white is best to get these muffins to hold together.
• vanilla extract – always a good idea to add vanilla extract to muffins!
• shredded zucchini – you’ll need about 2 small-medium zucchini. Use the small side of the box grater and be sure to squeeze out the water with these bags or a paper towel.

Optional Add-In’s

• Chocolate Chips – toss in a handful of regular or mini chocolate chips.
• Coconut Sugar – give each muffin a final sprinkle of coconut sugar before baking in the oven.

Star Ingredient: Quick Oats!

The main dry ingredient we’re using for these healthy zucchini oatmeal muffins is Bob’s Red Mill Quick Cooking Rolled Oats. Soft, tender quick oats add texture and chew to these mini muffins. But the best part? You can also use the quick oats to make your own oat flour!

To do so, simply measure out 1 1/4 cups + 2 Tablespoons quick oats into a food processor bowl or high powered blender. Pulse a few times until flour texture forms.

TIP: I like to keep a few cups of oat flour on hand. Just label the jar you’re storing the oat flour in so you remember what it is. Find my full tutorial on oat flour, here.

How to Make These Muffins

Making mini muffin recipes is just like making regular sized muffins, you’re just using a mini muffin pan. This particular recipe will make 24 mini muffins – it sounds like a lot but trust me these mini zucchini muffins go fast! Here’s how I like to do it:

Prep Muffin Tin

Preheat oven to 350ºF and spray mini muffin pan with oil, or use mini muffin liners.

Combine Dry Ingredients

If you need to make homemade oat flour, measure out 1 1/4 cups + 2 tablespoons quick oats and pulse into flour consistency. Then combine the flour with the 3/4 cup quick oats (not pulsed), baking soda, cinnamon and salt.

Whisk Wet Ingredients

In a separate bowl, whisk together maple syrup, olive oil, egg, egg white and vanilla extract.

Fold in Grated Zucchini

Add dry ingredients to large bowl of wet ingredients. Stir a few times, then fold in grated zucchini and continue to gently stir until just combined.

Fill Muffin Pan

Evenly distribute batter into 24 mini muffin pan, filling just about to the top.

Bake

Bake for 12-15 minutes, or until toothpick inserted in center comes out clean and the top of the muffins are a slight golden brown. Allow muffins to cool in pan for 5-10 minutes before carefully removing.

TIP: If not using liners, gently go around the edges of the muffin with a toothpick before lifting out. They’re fairly delicate when they’re fresh.

How to Store & Freeze

Leftover zucchini muffins can be stored in an airtight container at room temperature with a strip of parchment paper for up to 3 days.

Freeze: Place in a zip top freezer bag or freezer-safe airtight container. Freeze for up to 3 months. Thaw to room temperature before enjoying!

Serving Suggestions

These delicious muffins are great to have around for all the things! Since these are a bite-size treat, I love to make them for:

• Breakfast: I’ve been popping these zucchini mini muffins one handed like it’s my job. They go particularly well with a cup of coffee, too.
• Afternoon Snack: Whether you pack a few into a parchment paper bag for a grab-and-go snack, or enjoy one or two for an afternoon pick-me-up, they are a delicious little treat.
