Ingredient Notes
Rolled Oats
Old-fashioned rolled oats add a hearty texture to these muffins.
Soaking the oats in milk before mixing helps soften them and creates a more tender muffin texture.
Blueberries
Fresh blueberries work beautifully in this recipe.
Frozen blueberries can also be used. Add them directly from the freezer to prevent excess moisture and color from spreading through the batter.
Cinnamon
A small amount of cinnamon adds warm flavor and pairs nicely with blueberries.
Melted Butter
Melted butter helps create soft and moist muffins.
Allow it to cool slightly before adding it to the egg.
How to Make Blueberry Oatmeal Muffins
1. Soak the Oats
Add the rolled oats and milk to a medium bowl.
Stir together and allow the oats to soak for about 10 minutes.
This helps soften the oats.
2. Preheat the Oven
Preheat your oven to 375°F.
Line a 12-cup muffin pan with paper liners or lightly grease the cups.
3. Mix the Dry Ingredients
In a large mixing bowl, whisk together:
- All-purpose flour
- Granulated sugar
- Baking powder
- Ground cinnamon
- Salt
Mix until evenly combined.
4. Mix the Wet Ingredients
To the bowl of soaked oats, add:
- Egg
- Melted butter
- Vanilla extract
Whisk until well combined.
5. Combine the Ingredients
Pour the wet oat mixture into the bowl with the dry ingredients.
Gently stir until just combined.
Do not overmix.
6. Add the Blueberries
Gently fold the blueberries into the muffin batter.
Be careful not to crush the berries.
7. Fill the Muffin Cups
Divide the batter evenly between the prepared muffin cups.
Fill each cup approximately three-quarters full.
8. Add Optional Topping
If desired, mix the brown sugar and cinnamon together.
Sprinkle a small amount over each muffin before baking.
9. Bake
Bake for approximately 18–22 minutes, or until a toothpick inserted into the center comes out clean.
10. Cool and Serve
Allow the muffins to cool in the pan for about 5 minutes.
Transfer them to a wire rack.
Serve warm or at room temperature.
Tips for the Best Blueberry Oatmeal Muffins
Soak the Oats
Soaking the oats in milk helps soften them and creates a better texture.
Don’t Overmix the Batter
Mix only until the ingredients are combined.
Overmixing can make muffins dense.
Use Fresh or Frozen Blueberries
Both options work well.
If using frozen blueberries, add them directly from the freezer.
Toss Blueberries with Flour
If your blueberries tend to sink, gently toss them with 1 teaspoon of flour before adding them to the batter.
Check the Muffins Early
Ovens can vary.
Start checking the muffins around 18 minutes.
Blueberry Oatmeal Muffin Variations
Lemon Blueberry Oatmeal Muffins
Add fresh lemon zest to the batter for a bright citrus flavor.
Blueberry Banana Oatmeal Muffins
Replace part of the butter with mashed ripe banana for extra natural sweetness and moisture.
Blueberry Chocolate Chip Muffins
Add a small handful of chocolate chips along with the blueberries.
Whole Wheat Blueberry Oatmeal Muffins
Replace part of the all-purpose flour with whole wheat flour.
The muffins will have a slightly heartier texture.
Blueberry Nut Muffins
Add chopped walnuts or pecans for extra crunch.

Store them in an airtight container at room temperature for up to 2 days.
For longer storage, refrigerate for up to 5 days.
Place a paper towel in the container to help absorb excess moisture.
