Preheat and Prepare:

1. Preheat your oven to 350°F (175°C).
2. Grease a 9×5-inch loaf pan with nonstick spray or line it with parchment paper for easy removal.
3. In a medium bowl, whisk together the flour, baking soda, and salt. Set aside.

2. Mix Wet Ingredients:

1. In a large mixing bowl, beat the granulated sugar and butter together until light and creamy.
2. Mix in the eggs one at a time, ensuring they’re fully incorporated.
3. Stir in the mashed bananas until the batter is smooth.

3. Combine and Color:

1. Gradually fold the dry ingredients into the wet mixture until just combined. Avoid overmixing.
2. Divide the batter evenly into three bowls.
3. Add pink, purple, and neon green gel food coloring to each portion, stirring until the colors are vibrant.

4. Layer the Batter:

1. Scoop dollops of each colored batter into the prepared loaf pan, alternating colors for a swirled effect.
2. Sprinkle a layer of rainbow sprinkles between each batter layer for added fun.

5. Bake:

1. Place the pan in the preheated oven and bake for 45-65 minutes, or until a toothpick inserted into the center comes out clean.
2. Allow the bread to cool in the pan for 10-15 minutes, then transfer it to a wire rack to cool completely.

6. Prepare the Icing:

1. In a small bowl, whisk together the confectioners’ sugar and milk until smooth.
2. Adjust the consistency by adding more sugar for a thicker glaze or more milk for a thinner drizzle.

7. Decorate and Serve:

1. Drizzle the icing over the cooled bread, letting it cascade down the sides.
2. Top with additional rainbow sprinkles for a magical finish.
3. Slice and serve your colorful creation.
