Preheat oven to 375 F. Sift flour, baking powder and salt in a bowl. In the bowl of a stand mixer, cream butter flavored shortening and both sugars until light and fluffy. Add vanilla and eggs, mixing to incorporate. Stir in mashed banana.
Add dry ingredients and mix well, then stir in chocolate chips.
Scoop by tablespoonful onto an ungreased cookie sheet. Bake about 8 minutes until edges are light brown.
If you are going to dip them in some chocolate, melt the 1/2 cup of chocolate chips in a heat proof bowl over boiling water. Stir to help melt and when melted dip cookies.
If you don't dip them in chocolate, you might want to sprinkle them before baking, with a mixture of sugar and cinnamon. In fact make some both ways, you will love these cookies.
