These oatmeal blueberry muffins are a delightful way to start your day or enjoy as a snack. They are moist, flavorful, and packed with nutritious oats and juicy blueberries. Perfect for breakfast on the go or a mid-day treat, these muffins are sure to become a family favorite.
Most of the ingredients for these muffins are common pantry staples, but you may need to pick up fresh or frozen blueberries if you don't have them on hand. Additionally, make sure you have rolled oats, which are different from instant oats and provide a better texture for the muffins.

Ingredients for Oatmeal Blueberry Muffins
Flour: Provides the base structure for the muffins.
Oats: Adds texture and a slight nutty flavor.
Baking powder: Helps the muffins rise and become fluffy.
Salt: Enhances the overall flavor of the muffins.
Milk: Adds moisture and richness to the batter.
Vegetable oil: Keeps the muffins moist and tender.
Vanilla extract: Adds a sweet, aromatic flavor.
Eggs: Binds the ingredients together and adds structure.
Blueberries: Provides bursts of juicy sweetness in every bite.
Technique Tip for This Recipe
When folding in the blueberries, be sure to do so gently to avoid breaking them and turning the batter purple. Use a spatula and fold from the bottom of the bowl to the top, rotating the bowl as you go. This ensures the blueberries are evenly distributed without overmixing the batter, which can result in tough muffins.

How to Store / Freeze These Muffins
Allow the muffins to cool completely on a wire rack before storing. This prevents condensation from forming inside the storage container, which can make the muffins soggy.
For short-term storage, place the muffins in an airtight container. They can be kept at room temperature for up to 2 days. If you prefer, you can also store them in the refrigerator to extend their freshness for up to a week.
To freeze the muffins, first ensure they are completely cooled. Wrap each muffin individually in plastic wrap or aluminum foil. This helps to prevent freezer burn and keeps them tasting fresh.
Place the individually wrapped muffins in a large, resealable freezer bag or an airtight container. Label the bag or container with the date to keep track of their freshness.
When you’re ready to enjoy a frozen muffin, remove it from the freezer and let it thaw at room temperature for about 1-2 hours. For a quicker option, you can microwave the muffin on a low setting for 20-30 seconds.
If you prefer a warm muffin, preheat your oven to 350°F (175°C) and reheat the thawed muffins for about 10 minutes. This will bring back their freshly baked texture and flavor.
For an extra touch, consider sprinkling a bit of sugar on top of the muffins before reheating them in the oven. This will give them a delightful, slightly caramelized crust.
How to Reheat Leftovers
Oven Method:
- Preheat your oven to 350°F (175°C).
- Place the oatmeal blueberry muffins on a baking sheet.
- Cover them loosely with aluminum foil to prevent them from drying out.
- Heat for about 10-15 minutes or until warmed through.
Microwave Method:
- Place a muffin on a microwave-safe plate.
- Cover it with a damp paper towel to keep it moist.
- Microwave on medium power for 20-30 seconds. Check and add more time if necessary, but be careful not to overheat.
Toaster Oven Method:
- Preheat your toaster oven to 350°F (175°C).
- Place the muffins directly on the rack or on a small baking sheet.
- Heat for 5-10 minutes until they are warmed through.
Steam Method:
- Set up a steamer pot with water and bring it to a gentle simmer.
- Place the muffins in the steamer basket.
- Cover and steam for about 5 minutes. This method helps retain moisture and can make the muffins taste freshly baked.
Air Fryer Method:
- Preheat your air fryer to 300°F (150°C).
- Place the muffins in the air fryer basket.
- Heat for 3-5 minutes, checking frequently to ensure they don’t overheat.
