Now that we’re officially in baking season, I’m finally getting around to sharing the recipe for these banana walnut oatmeal muffins that I first posted in September. Better late than never, right?
Plus, these muffins will definitely be on repeat this winter. They taste just like a bowl of oatmeal in muffin form. Not only that, they’re incredibly easy to make during Sunday meal prep. As a result, busy mornings become much easier — simply microwave one for 30 seconds, spread on some nut butter, and you’re ready to go.
Why You’ll Love These Banana Walnut Oatmeal Muffins
These muffins are the perfect mix of wholesome and convenient. First, they’re made with simple pantry ingredients like oats, bananas, and walnuts. Additionally, oats provide fiber and help keep you full longer. Finally, they’re naturally sweetened with banana and maple syrup, making them a great breakfast or snack option.
- 2 ½ cups old-fashioned oats (keep 1 cup whole and grind the other 1.5 cup in a food processor)
- 2 overripe bananas
- 2 eggs
- ⅓ cup maple syrup
- ¾ cup milk or milk alternative
- 2 tsp vanilla extract
- 2 tsp baking powder
- ½ tsp baking soda
- ½ tsp salt
- 1 tsp pumpkin spice (or cinnamon)
- ½ cup walnuts (whole or pieces)
- 1 tbsp chia seeds or flax seeds (optional)
- Oats to sprinkle on muffin tops
- Preheat oven to 350 degrees and line a muffin tin with muffin wrappers or oil.
- Grind 1.5 cups of oats in a food processor until they have a flour-like consistency.
- Place in a small bowl and mix in the remainder of dry ingredients (whole oats, baking powder, baking soda, salt, and spice). Set aside.
- In a larger bowl, mash bananas until there are no lumps.
- Add wet ingredients (eggs, maple syrup, milk and vanilla) to bananas. Stir well.
- Slowly add dry ingredients to wet ingredients and mix. Add flax seeds or chia seeds (optional).
- Fold in the walnuts and allow mixture to sit for 5 minutes.
