This Healthy Blueberry Oatmeal Muffins recipe comes together in about 30 minutes and uses just one bowl for a quick and easy treat that your family will love!
Ingredients Breakdown
For this muffin recipe, you’ll need the following simple ingredients, and I promise you probably already have most of them at home!
1½ cups of rolled oats: Grab those whole rolled oats for chewy goodness. They not only give these muffins a hearty texture but also pack in all the health benefits of oats.
1 cup of milk (dairy or non-dairy): Use your favorite – almond milk, oat milk, or cow’s milk will all work beautifully.
½ cup of honey or maple syrup: Sweetness is key! Depending on your taste preference, you can dial it up or down, or even mix it up!
1 large egg: This helps bind it all together. For a vegan option, use a flax egg (1 tablespoon flaxseed meal + 2.5 tablespoons water, let it sit for a few minutes to thicken).
1 teaspoon of vanilla extract: Because who doesn’t love that hint of vanilla?
1 teaspoon of baking powder: This little magic ingredient helps our muffins rise and become fluffy.
½ teaspoon of baking soda: It gives them a light and airy texture.
½ teaspoon of salt: Just a couple of pinches to enhance all the flavors.
1 cup of fresh or frozen blueberries: The star of the show! Feel free to use whatever you have on hand, and if they’re frozen, there’s no need to thaw them. Bonus points for using seasonal local blueberries!
Let’s Get Cooking!
Now that we’ve covered the essentials, let’s dive into the simple step-by-step instructions for making these muffins that are bound to become your go-to recipe!
Preheat your oven to 350°F (175°C) and line a muffin tin with paper liners. You want that oven nice and hot to create the perfect muffin dome!
In a large bowl, combine the rolled oats, milk, honey or maple syrup, egg, and vanilla extract. Stir it all together until it’s just mixed. I usually do this until it looks creamy and inviting, but don’t worry about any lumps!
In another bowl, mix together the baking powder, baking soda, and salt. This ensures the leaveners are evenly distributed, so you won’t have a muffin that poofs up oddly on one side, which nobody wants!
Gradually add the dry ingredients to the wet ingredients while stirring gently. Mix until just combined. Over-mixing can make the muffins tough, and we definitely want these to be tender!
Now for the fun part: fold in the blueberries gently. You want them evenly spread throughout the batter without bursting them all!
Divide the batter evenly among the muffin cups. You can fill them about ¾ full for nice, fluffy muffins.
Pop them in the oven and let them bake for about 18-20 minutes. You’ll know they’re done when you poke a toothpick into the center and it comes out clean. Woohoo!
Allow the muffins to cool in the tin for a few minutes before transferring them to a wire rack to cool completely. Honestly, you’ll want to let them cool a bit, but the heavenly smell will test your willpower!
