Oatmeal Blueberry Banana Muffins

These fluffy, moist Oatmeal Blueberry Banana Muffins are easy to make and delicious to eat. They are perfectly baked to have that beautiful dome shaped muffin top.

These tender muffins are great to eat for breakfast. You can even prepare the batter the night before and pop them in the oven the next morning to have warm, fresh muffins to start your day.

The oats in these muffins make them feel a bit heartier than the average muffin. The juicy blueberries and banana are paired together to make these muffins moist and full of flavor.

After these muffins are baked, you brush them with melted butter and coat the tops in turbinado, or raw, sugar which gives them a perfect little crunch in every bite!

These are best when they are still warm from the oven and slathered in butter, of course. A quick and perfect breakfast, in my opinion!

Why You Will Love These

• The fruit. The banana in these muffins not only tastes delicious, but it makes them super moist. The blueberries add beautiful color and their flavor combined with the banana is perfect! This is a great way to use up overripe bananas.
• The muffin top. Who doesn't love a good muffin top? These guys are baked at a high temperature for the first part of the baking to help jump start that dome forming. This makes these muffins look like the ones you would get at a breakfast diner! The turbinado sugar on top of the muffins adds a perfect crunch.
• The texture. Allowing the batter to sit for at least an hour, but ideally overnight, gives the batter time to thicken. This helps give these muffins their perfect fluffy consistency. The banana, oil and buttermilk all help to prevent these from drying out.

Ingredients Needed

Here are notes about some of the ingredients needed to make these blueberry banana oatmeal muffins. You can all of the ingredients at your local grocery store or at an online retailer, like Amazon.

• Cooking spray: You can use muffin liners for these, but you will still want to be sure to spray cooking spray on the tops of the muffins tins so your muffin tops don't stick.
• Flour: All purpose flour measured by scooping into the measuring cup and leveling with a knife.
• Sugar
• Baking powder
• Baking soda
• Salt
• Oats: Old fashioned rolled oats will work best for this and give the texture that makes these muffins so good! Instant or quick oats would work, but will give the muffins a different texture. Steel cut oats would not work for this recipe.
• Banana: Ripe, mashed bananas are what you will need here for the most delicious flavor. I have used bananas that aren't quite ripe and the flavor isn't nearly as good, so wait until you have those extra ripe ones! You need about 2-3 bananas.
• Eggs
• Buttermilk: Full fat or low fat buttermilk works fine for this.
• Vegetable oil: If you have canola oil, that would work too. You really just want to be using a flavorless oil for this.
• Vanilla extract
• Blueberries: Fresh blueberries work great. Frozen blueberries would work too.
• Butter: You will use melted butter to brush on the tops after baking.
• Turbinado sugar: The muffin tops are dipped in the turbinado sugar after brushing them with the melted butter. This gives them such a fancy looking, almost sparkly top. The crunch of the sugar is pretty fun too.

Step by Step Instructions

Here is how to make this delicious blueberry muffin recipe. You will need a 12-cup muffin pan and muffin liners. I prefer to use these white muffin liners, but any standard size liners will do! See the recipe card below for the full ingredient list and instructions.

STEP 1: In a large mixing bowl, combine the flour, sugar, baking powder, baking soda and salt. Stir this with a whisk.

STEP 2: Add the oats and stir to combine. Set this bowl aside.

STEP 3: In a separate large bowl add the wet ingredients (bananas, eggs, buttermilk, vegetable oil, and vanilla.) Whisk ingredients together until fully combined.

STEP 4: Carefully add the banana mixture to the flour mixture. Fold the two mixtures together with a rubber spatula just until combined and the dry ingredients are fully mixed in.

STEP 5: Add the blueberries to the bowl and gently fold them in until combined.

STEP 6: Tightly cover the bowl and place it in the refrigerator for at least one hour, or overnight.

STEP 7: Preheat oven to 425°. Spray the top of a 12-cup muffin pan. Line muffin cups with a paper liners.

STEP 8: Fill each muffin liner about ¾ of the way full with the muffin batter.

STEP 9: Bake in the 425° oven for 9 minutes. Reduce the heat to 350° and continue to bake for 7-9 minutes or until a toothpick inserted in the middle comes out mostly clean.

STEP 10: Remove the muffins from the oven and let them cool in the pan for 5 minutes. Carefully remove them from the pan and transfer to a wire rack to cool 10 more minutes or until fully cooled.

STEP 11: Place the turbinado sugar in a shallow dish or bowl. Working with one muffin at a time, brush the top with the melted butter and then dip or roll the muffin top in the turbinado sugar.

Expert Tips

Here are some tips to help you make this great recipe:

• To mash bananas, peel and place them in a bowl. Using a fork, mash them until they are mostly smooth. A few lumps in there will be okay, but you'll want the consistency to be pretty smooth.
• To lightly beat the eggs, crack the eggs into a bowl. Using a fork or a whisk, quickly beat the eggs until the yolk and white are thoroughly combined and light pale in color, about 15-20 seconds.
• Do not over mix your batter! Only mix until you no longer see the dry ingredients. Over mixing will make your muffins tough and dry, so be careful!
• Use a large cookie scoop to put the batter into the muffin liners. It's less of a mess and it helps you evenly distribute the batter.
• Using a toothpick to test the doneness of the muffins will help you get them baked to perfection. Insert a toothpick in the center of a muffin and if it comes out mostly clean with a few crumbs, it's ready. They are not ready if the toothpick comes out wet, and if it comes out totally dry, you've probably cooked them a bit too long!

FAQ

You can freeze these muffins in an airtight container or zip top bag for up to 3 months. When ready to heat, thaw on the counter or in the refrigerator. You could also wrap them in a paper towel directly out of the freezer and microwave for 30-45 seconds, or until thawed and warm.
