I remember a little while back, my kids were begging for homemade muffins. I ended up making something else, and while they enjoyed it, the muffin request lingered. Not too long after, I decided it was time to bake a batch, and I wanted something packed with goodness. My daughter, bless her heart, even caught me adding shredded carrots to the batter, giving me a skeptical look, but let me tell you, after one bite, they were sold! My kids ended up devouring two each for breakfast and immediately asked if there were more for the next day.

Tips for Baking Amazing Muffins

Getting these wholesome muffins just right is easy with a few simple pointers.

  • Prepare Your Muffin Pan Properly: My preferred method is to generously coat the muffin tin cups with a good nonstick cooking spray. While paper liners are an option, I sometimes find they stick to the muffins, potentially leaving behind those precious bits of baked goodness, like those tasty golden raisins.
  • Remove Excess Moisture from Veggies: Zucchini and carrots naturally hold a lot of water, and leaving too much in the batter can lead to soggy muffins. After grating them, I like to gently squeeze out the extra liquid. You can wrap the shredded vegetables in a clean towel or several layers of paper towels and twist to extract the moisture. Doing this over a bowl is handy to catch the liquid.
  • Combine Wet and Dry Separately: To achieve the best texture, it’s helpful to mix your dry ingredients thoroughly in one bowl and your wet ingredients (like eggs and oil) in another before combining them. You can mix the wet ingredients as much as needed. However, once the wet and dry ingredients are combined, only mix until everything is just incorporated. Overmixing can develop the gluten in the flour too much, which can make muffins dense. Since these muffins already have a hearty texture from the oats and whole wheat, gentle mixing is key.
  • Fill Cups Evenly: For uniformly sized muffins, fill each cup about three-quarters full. A standard ice cream scoop works perfectly for this job, ensuring consistent portions every time you bake.
  • Don’t Forget to Preheat and Test: Make sure your oven is fully preheated to the correct temperature (around 350°F or 175°C) before putting the muffins in. Bake them until a toothpick inserted into the center comes out clean and the tops spring back lightly when touched, typically around 20 minutes. Letting them cool completely in the pan before removing helps them set properly.

Why These Muffins Are a Winner

Honestly, the fact that my kids loved these so much speaks volumes. They have such a wonderfully tender and moist crumb, while still being hearty enough to feel substantial for a quick breakfast on their own. Thanks to the combination of oats, whole wheat flour, raisins, carrots, and zucchini, they provide plenty of fiber and beneficial vitamins. The vegetables also play a huge role in keeping the muffins incredibly moist without needing excessive oil. They are truly a delightful way to enjoy a healthier treat!

Frequently Asked Questions About the Muffins

Are these muffins suitable for breakfast?

Absolutely! They are packed with wholesome ingredients like oats, whole wheat, and vegetables, making them a nutritious and satisfying way to start your day.

Can I use different types of flour?

This recipe uses a mix of plain and whole wheat pastry flour for texture and nutrients. While you might experiment, using different flours could change the texture and moisture level of the muffins.

Do I have to add the golden raisins?

No, the golden raisins are listed as optional. You can leave them out if you prefer, or substitute them with other add-ins like chopped nuts or chocolate chips, though that would change the “healthy” aspect slightly.

How long will these muffins last?

You can store the cooled muffins in an airtight container at room temperature for about 4 to 5 days.

Can I freeze these muffins?

Yes, once completely cooled, you can wrap individual muffins tightly in plastic wrap or foil and place them in a freezer bag or container. They should keep in the freezer for up to 2-3 months. Thaw them at room temperature or gently warm them.

Why do I need to squeeze liquid from the zucchini and carrots?

Zucchini and carrots contain a lot of water. Removing some of this excess moisture prevents the muffins from becoming too wet or gummy, ensuring a light, moist crumb instead of a soggy one.

Is whole wheat pastry flour necessary?

Whole wheat pastry flour provides the nutrition of whole wheat but has a finer texture and lower protein content than regular whole wheat flour, resulting in a more tender muffin. Using regular whole wheat might make the muffins a bit denser.

Description

These Zucchini Carrot Oatmeal Muffins are incredibly moist, wholesome, and packed with delightful flavors! Made with healthy ingredients like whole wheat flour, oats, fresh zucchini, and sweet carrots, they are perfect for a nourishing breakfast or a satisfying snack!


Ingredients

For the Muffins

  • ½ cup (50 grams) old-fashioned rolled oats
  • 1 cup (120 grams) plain flour
  • 1 ½ cups (190 grams) whole wheat pastry flour
  • 1 ½ cups (315 grams) granulated sugar
  • 1 tablespoon (15 grams) double-acting baking powder
  • 1 ½ teaspoons (4 grams) warm ground cinnamon
  • 1 teaspoon (5 grams) fine sea salt
  • 3 large eggs (about 150 grams total), room temperature
  • 1 large egg white (about 30 grams)
  • ¾ cup (180 ml) neutral cooking oil
  • 1 cup (115 grams) freshly grated zucchini
  • 1 cup (115 grams) finely grated carrot
  • ¾ cup (110 grams) optional golden raisins

Instructions

  1. Start by preheating your oven to 350°F (175°C). Prepare a standard 12-cup muffin tin. You can line the cups with paper liners or coat them well with nonstick cooking spray.
  2. Gently squeeze the excess water from the grated zucchini and carrots. This step helps prevent soggy muffins.
  3. In a spacious mixing bowl, whisk together all the dry ingredients. Set this bowl aside for now.
  4. Using a different bowl, whisk the eggs and oil until they are well combined. Then, stir in the grated zucchini and carrots.
  5. Pour the wet mixture into the bowl containing the dry ingredients. Mix everything gently until just combined. Be careful not to overmix the batter.
  6. Divide the batter evenly among the prepared muffin cups, filling each one about three-quarters full. Bake in the preheated oven for approximately 20 minutes. You’ll know they’re ready when a toothpick inserted into the center of a muffin comes out clean and the tops spring back lightly when you touch them.
  7. Let the muffins cool completely in the baking pan before serving them.

Notes

Storage: For storage, keep the cooled muffins in an airtight container at room temperature for up to 4 to 5 days.
