Start by combining the flour with the baking powder and baking soda. Next, cream together the butter, eggs, egg yolk, and sugar. Once well combined, add the flour mixture and set this first batter aside.

Make the second batter by mashing the bananas with a fork and mixing them with the sour cream (to make the sour cream, simply mix lemon juice, heavy cream, and yogurt).

With the resulting batter, make the muffins. I didn't make them very large, using about a tablespoon of batter per muffin cup. Bake at 350°F (180°C) for 20 minutes, then remove from the oven and let them cool completely.

Now make the frosting by beating all the ingredients at room temperature until well combined.

Indulge in this sweet treat, perfect to enjoy cold for breakfast, as a snack, or as a delightful dessert.. enjoy your meal 🌻🌻🌻🌻🌻!
