1 Preheat the oven to 350°F. Cream the butter and sugar together until light and fluffy. Add the egg and continue to beat until the mixture is light and fluffy.
2 In a bowl, mix the mashed bananas and baking soda. Let sit for 2 minutes. The baking soda will react with the acid in the bananas which in turn will give the cookies their lift and rise.
3 Mix the banana mixture and vanilla into the butter mixture. Mix together the flour, salt, and spices and sift into the butter and banana mixture and mix until just combined.
4 Fold into the batter the chocolate chips and/or pecans if using. Drop in dollops onto parchment paper-lined baking sheet. Bake for 11-13 minutes or until nicely golden brown. Let cool on wire racks.
I sometimes use a tablespoon of cinnamon and no other spices.
Dark chocolate chips, or peanut butter chips are my preferred.
