I always use Kosher salt in my kitchen! If using table salt, start with half the amount and adjust to taste, as it is much "saltier" by volume.
Instructions
Preheat an oven to 375° F and line a muffin pan with liners.
In a small microwave safe bowl melt the butter. Let it set for 5-10 minutes to cool. Once cool mix in (using a fork) the brown sugar, cinnamon, vanilla and flour. Use the fork to break up the large clumps. Set aside.
In a large bowl using a fork mash the bananas until no large pieces remain. Mix in the sugars, eggs, yogurt, oil and vanilla extract. Mix until well combined.
To the wet ingredients mix in the flour, salt, cinnamon and baking soda. Mix until just combined. Do not overmix.
Scoop into the lined muffin pans, filling just under ¾ of the way full. Top with the crumb topping, breaking up the large clumps. Bake for 16-20 minutes or until a toothpick inserted in the middle comes out clean.
Allow the muffins to cool enough to remove them from the pan. Place on a wire rack and cool completely. While the muffins are cooling, in a small bowl, mix together the powdered sugar, milk and vanilla extract. When the muffins are completely cool drizzle over the icing.
Notes
This recipe makes roughly 16 muffins. Depending on how much you fill each liner. I like to fill each muffin liner just between ½ and ¾ of the way full.
