I love baking healthy muffins because they’re quick, easy and the perfect size for snacking. Like these Healthy Blueberry Muffins and our favorite Banana Muffins, these blueberry oatmeal muffins are a healthy muffin recipe. You’d never guess it though after taking a bite! You will love the soft, fluffy texture and sweet flavor of these blueberry oatmeal muffins. 

Like most muffins, these freeze wonderfully for a healthy breakfast or quick snack later on. I’ve even been known to enjoy one for dessert!

The Best Blueberry Oatmeal Muffins

  • The key to making the best oatmeal muffins is soaking the oats before adding them to the batter. While they soak, the oats absorb some of the liquid and soften up so that your muffins will have the best texture.
  • These wholesome muffins are made with good for you ingredients, including whole wheat flour, old fashioned rolled oats and blueberries.
  • You might want to make a double batch. These muffins always seem to disappear too quickly!

Blueberry Oatmeal Muffins Recipe Ingredients

  • Plain Greek Yogurt: Helps to make the muffins soft and tender.
  • Milk: Softens the oats and gives the muffins a softer crumb.
  • Old-Fashioned Rolled Oats: To put the “oatmeal” in these oat muffins. Be sure to use old fashioned rolled oats, not quick cooking oats or steel cut oats.
  • Butter: Using butter in muffins gives them the best flavor.
  • Honey: To sweeten the muffins. You can substitute pure maple syrup if desired.
  • Eggs: Provide structure and help the muffins to rise and become light and fluffy as they bake.
  • Vanilla Extract: For flavor.
  • Lemon Zest: Adds a touch of bright lemon flavor. For an alternative flavor, you can use 1/2 teaspoon of ground cinnamon in place of the lemon zest. I’ve tried both!
  • Baking Powder & Baking Soda: These help the muffins to puff up in the oven so that they turn out perfectly light and fluffy.
  • Salt: Enhances all of the other flavors. Don’t skip it!
  • White Whole Wheat Flour: If you can’t find white whole wheat flour, regular whole wheat flour will work and will give the muffins a slightly heartier texture and flavor. You can also use all-purpose flour.
  • Blueberries: Both fresh and frozen work well here. If frozen, do not thaw before adding to the muffin batter.

How to Make Blueberry Oatmeal Muffins

These blueberry oatmeal muffins are easy to make! 

  1. In a medium bowl, whisk together the Greek yogurt and milk until smooth. Stir in the oats. Let the mixture sit for 10-15 minutes to soften the oats. Greek yogurt, milk and eggs combined in bowl.
  2. While the oats soak, whisk together the melted butter and honey in a large mixing bowl. Then whisk in the eggs, vanilla and lemon zest. Wet ingredients in mixing bowl.
  3. Add the baking powder, baking soda and salt to the wet ingredients. Whisk until completely combined. You don’t want any clumps of these ingredients left in the muffins.
  4. Use a rubber spatula to mix in the soaked oats along with any milk and yogurt from the bowl. Softened oats added to mixing bowl.
  5. Mix in the flour until barely combined, being careful to not overmix.
  6. Gently fold in the blueberries. Fresh blueberries added to batter in mixing bowl.
  7. Scoop the batter into a greased muffin pan (or use parchment paper liners). The muffin wells will be filled most of the way to the top. Scooping batter into muffin pan.
  8. Bake at 375° F for 17-20 minutes, until a toothpick inserted into the center of a muffin comes out clean.

Let the muffins cool in the pan for 5-10 minutes before removing them to a wire rack to finish cooling. Enjoy the muffins warm or at room temperature.

Recipe Tips

  • When measuring the flour, lightly spoon it into your measuring cup and then level it off. Scooping the flour directly with the measuring cup can cause too much flour to get packed in.
  • Be careful to not over-mix the batter after adding the flour. Overmixing can cause the muffins to turn out tough or dense, rather than soft and fluffy.
  • The muffins are delicious made either with lemon zest or cinnamon, so use one or the other depending on what you have on hand and your flavor preferences. See the recipe card below for amounts.
  • If using frozen blueberries, mix them into the batter straight from the freezer. Thawing them may cause the muffin batter to turn purple.
  • You can substitute other berries for the blueberries, such as raspberries or blackberries.

How to Store

I always freeze any leftover muffins right away once they’re cool, because they stay freshest in the freezer. You can also store these at room temperature if you prefer.

  • Room Temperature: Muffins may be stored in an airtight container at room temperature for up to 2 days. Lay a paper towel in the bottom of the container, under the muffins.
  • Freezer: Once completely cool, freeze in an airtight container for up to 3 months.
  • To Reheat: If frozen, thaw for about 30 minutes at room temperature or use your microwave’s defrost setting. Then gently warm for a few seconds in the microwave.
