Creating Soft & Fluffy Banana Muffins is a seamless process when you follow these easy steps:

1. Preheat your oven to 350°F (175°C). Arrange a rack in the center of the oven.
2. Grease the Muffin Tin: Prepare a standard muffin tin by greasing it lightly or using muffin liners.
3. Mash Bananas: In a large bowl, mash the ripe bananas with a fork until smooth.
4. Add Melted Butter: Stir in the melted butter into the mashed bananas until well combined.
5. Mix in Baking Soda and Salt: Add baking soda and a pinch of salt to the mixture and stir.
6. Combine Sugar and Egg: Mix in the sugar, beaten egg, and vanilla extract until fully incorporated.
7. Add Baking Powder: Stir in the baking powder.
8. Incorporate Flour: Gradually add the flour and mix until just combined. Be careful not to overmix, as this can make the muffins dense.
9. Fill Muffin Cups: Scoop the batter into each muffin cup, filling them about 2/3 full.
10. Bake: Place the muffin tin in the oven and bake for 20-25 minutes or until the tops are golden brown and a toothpick inserted in the center comes out clean.
11. Cool: Once baked, remove the muffins from the oven and let them cool in the tin for about 10 minutes, then transfer them to a wire rack to cool completely.

These steps will lead you to a batch of soft & fluffy muffins that everyone will adore. Enjoy the aroma that fills your kitchen and the delightful taste with every bite.
