• Start by preheating your oven to 350 degrees F (175 degrees C) and preparing two baking sheets with parchment paper.

For Cookies:

• In a bowl, mix together the flour, baking soda, and salt until well combined.
• Using an electric mixer, beat the shortening and white sugar together in another bowl until you achieve a smooth texture. Add in the mashed banana, eggs, and vanilla essence, and mix thoroughly.
• Slowly incorporate the dry ingredients into the mixture until just combined; you should end up with a sticky dough. Use a tablespoon to drop rounded amounts of dough onto the prepared baking sheets, leaving about 2 inches of space between each.
• Place the baking sheets in the preheated oven and bake for 10 to 15 minutes, switching the positions of the racks halfway through, until the cookies are slightly golden.

For Glaze:

• While the cookies are baking, prepare the glaze by mixing the confectioners' sugar, softened butter, milk, and additional vanilla in a medium bowl. Adjust the milk until you reach a drizzling consistency.
• Once the cookies are baked, remove them from the oven and transfer to wire racks. Drizzle your glaze over the warm cookies and let them cool for about 25 minutes before enjoying.
