Ingredients For Banana Oatmeal Blueberry Muffins

• Rolled oats (I used gluten free certified oats and organic).
• Liquid (water or milk) – or plant based milk if you want the banana blueberry muffin – dairy free.
• Flour – you can use regular all purpose flour. Or use a gluten free flour mix if you want gluten free muffins.
• Mashed bananas – the creamy, thickening power of ripe mashed banana is perfect for replacing some of the fat and sugar content.
• Blueberries – fresh or frozen.
• Butter (a neutral oil or vegan butter will work too for dairy free version) – for moisture and flavor.
• Egg – the biding agent, for structure.
• Maple sugar (or your favorite granulated sugar) – as sweetener.
• Baking powder– the rising agent.
• Vanilla extract and salt – for flavor enhancement.

For Crumble Topping You Will Need:

• rolled oats
• butter
• sugar
• flour
• cinnamon

How To Make Blueberry Banana Oatmeal Muffins 

First preheat the oven to 400 degrees Fahrenheit. If necessary, lightly grease the muffin cups or add cupcake liners. Set aside.

Step 1. Combine the wet ingredients:

• Mash the bananas with a fork. You will get approximately 1 cup from 2 large bananas or 3 smaller bananas. Add to a bowl together with the egg, melted butter, vanilla extract and apple cider vinegar. Mix to combine.

Step 2. Soak the rolled oats:

• To the same bowl, add the oats (1 cup) and fold together until well incorporated. Let them soak for 7-10 min to expand and absorb as much as possible the moisture. Meanwhile prepare the rest of ingredients.

Step 3. Mix in the dry ingredients:

• To that add the dry ingredients (maple sugar, flour, salt and baking powder). Reserve 1-2 tablespoons of flour to coat the blueberries.
• Then add the blueberries (coated with flour), gently incorporate them into the muffin batter.
• Spoon the batter into the prepared muffin tins, filling each about three-fourths full. 

Step 4. Make the crumble topping (optional):

• Add all ingredients in a small bowl. Mix with your hand to combine. 
• Sprinkle the topping evenly on top of the unbaked muffins.

Step 5. Bake the blueberry banana oat muffins:         

• Bake the muffins at 400F for 10 minutes then reduce the temperature to 375F and bake for another 20-25 minutes. If you’re using gluten free flour you might need additional 5-10 minutes.
• Cool the muffins in the pan on a rack for 5 minutes, then remove to a wire rack to cool completely. Once cooled the texture improves and stiffens, and the insides aren’t wet anymore.

Dairy Free & Gluten Free Option

• Use coconut milk as a substitute for the regular milk but there are many other dairy free, milk alternatives like almond, cashew, hemp or oat milk – they all work.
• Instead of regular butter, I use a plant based butter, but you can easily use some unflavored oil, like avocado oil or grape-seed oil.
• For gluten free version use a gluten free flour mix. Using a single type of gluten free flour like rice or sorghum might yield a really crumbly texture and probably dry.

Tips For Perfect Oatmeal Banana Blueberry Muffins                   

• Toss the blueberries in some flour before mixing all with wet ingredients. This will keep the blueberries from sinking to the bottom of the muffin.
• Soaking the oats with wet ingredients for 10 minutes creates a thicker and creamier muffin batter subsequently taller and heartier blueberry banana oat muffins.
• The thicker the muffin batter, the taller and puffier the blueberry banana oatmeal muffin will be.
• Apple cider vinegar gives these gluten free blueberry muffins a distinctive, slightly tangy flavor that a buttermilk usually gives. The acid combined with baking powder also helps the muffins rise.
• Over-mixing the batter can cause tough muffins.
• Fresh blueberries or frozen both work. Be warned that if you choose frozen, the muffin batter may get a little of a blueberry-purple color.
• Let the muffins cool completely on a wire rack before eating. The texture will settle and harden once cooled.

How To Store The Banana Blueberry Oatmeal Muffins 

• Once the banana oatmeal blueberry muffins have completely cooled, place them in a freezer bag or an air tight container. These gluten free muffins are good frozen up to 3 months.
• To defrost just place them in the refrigerator overnight, and they’re ready to go in the morning.
• During the cold season they can stay on the kitchen counter (covered) for up 4-5 days . In the summer these blueberry banana oat muffins don’t really hold up more than 2-3 days.
