Healthy Blueberry Oatmeal Muffins
Life is all about balance. While I love sharing regular muffin recipes (have you tried our Pumpkin Streusel Muffins or Lemon Poppyseed Muffins?), I also enjoy making lighter recipes too. This oatmeal version is one I keep handy to lighten the ole’ diet.
You’ll either need a food processor to turn old fashioned oatmeal into oat flour, or you can buy it in the grocery store. Since I don’t use oat flour on the regular, I prefer to process my own. Because oatmeal is a mainstay in our kitchen! Try our Banana Oatmeal Bars next!
Why This Recipe Works:
- ONE BOWL – This simple muffin recipe is made in one bowl. You’ll also need a food processor to grind the oatmeal into flour.
- MOIST – The mashed over-ripe bananas and blueberries help keep these muffins super moist.
- FULL OF BLUEBERRIES – These muffins are chock full of juicy blueberries. You’ll love the texture of the muffins like we do.
- NUTRIENT DENSE – These moist muffins are loaded with potassium and are a good source of fiber and protein. Instead of refined sugar and flour, we’re using honey and oatmeal.

What You’ll Need:
- Over-Ripe Bananas
- Sour Cream Light
- Honey
- Vanilla Extract
- Large Eggs
- Unsalted Butter
- Old Fashioned Oatmeal
- Baking Powder
- Baking Soda
- Kosher Salt
- Ground Cinnamon
- Frozen Blueberries (or fresh blueberries)

How to make Blueberry Banana Oatmeal Muffins:
Step 1
Prep. Preheat oven to 350 degrees, and prepare a 12-cup muffin pan with paper liners.
Step 2
Process oatmeal. Add the old fashioned oatmeal to a food processor. Pulse until the oats resemble flour (or close to it).

Step 3
Combine wet ingredients. In a large mixing bowl, combine the wet ingredients – sour cream, honey, vanilla extract, eggs, and the melted and slightly cooled butter. Whisk immediately until very well combined.
Step 4
Add dry ingredients. Then add the dry ingredients to the bowl – the processed oatmeal, baking powder, baking soda, kosher salt, and cinnamon. Use a spoon to mix again.


Step 5
Add blueberries. Then add the frozen blueberries and gently stir to combine.
Step 6
Add batter to a muffin pan. Use a cookie scoop or measuring cup to add the blueberry muffin batter to the prepared pan. Fill to the top of the liners. This batter will make 12 muffins.


Step 7
Bake. Bake blueberry banana muffins for 24-25 minutes or until done. The muffins will still be a bit wet in the centers but that’s ok.
Step 8
Cool. Let muffins rest in the muffin pan for 10 minutes before carefully removing to a cooling rack.

Storing and Freezing:
- Store blueberry oatmeal muffins in an airtight container at room temperature (or refrigerator) for 3-4 days.
- Freeze these scrumptious muffins in freezer bags for 2-3 months. I normally wrap each muffin in cling wrap and then place in freezer bag.
Recipe FAQs:
Yes, either fresh or frozen blueberries work great in this recipe. We tend to use fresh when they are in season.
Use certified gluten-free oats to make them gluten-free.
Enjoy them as-is or with a dollop of nut butter, yogurt, or a drizzle of honey.
