What is Banana Walnut Oat Muffin?
Banana Walnut Oat Muffins are a delightful variation of the classic muffin, combining the natural sweetness of ripe bananas with the hearty texture of rolled oats and the crunchy goodness of walnuts. The moist texture comes from the bananas, while the oats provide fiber and chewiness. Walnuts offer a subtle crunch and a nutty flavor that complements the sweetness of the bananas perfectly.

Origin of Banana Walnut Oat Muffins
The idea of combining bananas and walnuts in baked goods dates back centuries. Bananas, native to Southeast Asia, became widely used in baking in the 19th century. The addition of walnuts, a popular nut in both sweet and savory dishes, brings out the earthy flavors in the bananas. When oats were introduced into baking, they became a favorite ingredient due to their health benefits and texture. Banana Walnut Oat Muffins have become a popular recipe in homes, especially for their wholesome, nourishing qualities.

- 1 tsp baking powder
- 1/2 tsp salt
- 1 tsp cinnamon
- 1/4 tsp nutmeg (optional)
Wet Ingredients
- 3 ripe bananas, mashed (about 1 1/4 cups)
- 1/2 cup brown sugar (light or dark)
- 1/4 cup granulated sugar
- 1/3 cup melted coconut oil or vegetable oil
- 2 large eggs

- 1 tsp vanilla extract

Step-by-Step Directions and Preparation Method: Banana Walnut Oat Muffins

1. Preheat the Oven
Begin by preheating your oven to 350°F (175°C). Line a muffin pan with parchment liners or lightly spray the muffin cups with cooking spray. This will help prevent the muffins from sticking.
2. Combine the Dry Ingredients
In a large bowl, whisk together the flour, oats, baking soda, baking powder, salt, cinnamon, and nutmeg (if you’re using it). These dry ingredients will form the base for your muffin batter, providing structure and flavor.
3. Mix the Wet Ingredients
In a separate bowl, mash the bananas until smooth. Then, add the brown sugar, granulated sugar, melted oil, eggs, milk, and vanilla extract. Mix everything together until smooth and well combined. The bananas will provide the natural sweetness and moisture, while the oils and eggs will help bind the ingredients.
4. Combine Wet and Dry Ingredients
Pour the wet ingredients into the bowl with the dry ingredients. Stir gently using a spatula or wooden spoon until just combined—don’t overmix. Overmixing can result in dense muffins, so it’s important to keep the mixing minimal.
5. Add the Walnuts and Optional Mix-ins
Fold in the walnuts and any optional mix-ins like chocolate chips or raisins. The walnuts will add a delightful crunch and a nutty flavor that complements the banana and oats perfectly.
6. Fill Muffin Cups and Bake
Spoon the batter into the muffin cups, filling them about ¾ full. For a decorative touch and extra crunch, sprinkle a few extra walnuts on top before baking. Place the muffin pan in the oven and bake for 18-22 minutes, or until a toothpick inserted into the center of the muffins comes out clean.
7. Cool and Serve
Once baked, allow the muffins to cool in the pan for about 5 minutes, then transfer them to a wire rack to cool completely. These muffins are best enjoyed warm, but they’ll stay moist for a few days at room temperature.
Tips & Variations: Banana Walnut Oat Muffins
Healthier Version
If you’re looking to make these muffins a bit healthier, you can replace half of the oil with applesauce. This reduces the fat content and adds more natural sweetness.
Gluten-Free Option
For a gluten-free version of this recipe, substitute the all-purpose flour with a 1:1 gluten-free flour blend, and make sure to use certified gluten-free oats.
Extra Banana Flavor
For those who love the taste of banana, you can intensify the flavor by adding 1-2 tbsp of banana pudding mix or simply mashing an extra ½ banana into the batter. This will enhance the natural banana flavor.
Crunchy Tops
For an added crunch and a bit of extra sweetness, try sprinkling turbinado sugar (or any coarse sugar) on top of the muffins before baking. This will give them a lovely, crispy top.
Make-Ahead and Freezing
These muffins freeze well for up to 2 months. Simply place them in an airtight container or freezer bag, and when you’re ready to enjoy, just pop them in the microwave or oven to warm them up. They’re perfect for meal prepping or stocking up for busy mornings.
