Light and fluffy, these Easy Banana Muffins are loaded with fresh bananas. This simple one-bowl recipe comes together in no time! See below the recipe card for step-by-step images.
Preheat oven to 400º F. Line a 12-slot muffin tin with paper liners.
In a large bowl whisk together the flour, sugar, baking powder, and salt.
Using a measuring cup that holds at least 1 cup, pour in the vegetable oil, then add the egg. Then fill to the 1-cup mark with the milk. Add vanilla and whisk until combined.
Add milk mixture to the bowl with flour mixture and stir just until combined (do not over mix).
Gently fold in the mashed banana.
Evenly divide the batter between the muffin cups filling about 3/4 full.
Bake for 17-20 minutes until tops are no longer wet and a toothpick inserted into the middle of a muffin comes out clean.
Remove from oven and allow to cool for about 10 minutes. Eat and enjoy!
