2 1/4 cups all purpose flour (if you want healthy use 1 3/4 cups whole wheat flour and 1/2 cup of wheat germ)
1/2 teaspoon baking soda
1/2 teaspoon baking powder
1/2 teaspoon salt
1/2 cup unsalted butter
1 cup brown sugar
2 large eggs
2 teaspoons vanilla extract
2/3 cup banana chips, loosely chopped
1 cup chocolate chips
2/3 cup toasted walnuts, chopped
Preheat oven to 375 degrees, racks in middle/upper middle. Line two baking sheets with parchment paper.
Whisk together the flour, baking soda, baking powder, and salt. Set aside.
In a large bowl, or stand mixer, beat the butter until lightly and fluffy, then beat in the sugar until it is the consistency of a thick frosting. Beat in the eggs one at a time, incorporating each fully before adding the next, and scraping down the sides of the bowl a few times along the way . Stir in the vanilla. Add the reserved flour mix in two increments, stirring/mixing a bit between each addition (but not too much). By hand, stir in the banana chips, chocolate chips and walnuts - mix just until everything is evenly distributed.
Drop 1 heaping tablespoon of dough for each cookie onto the prepared baking sheets 2 inches apart and bake for about 7 - 8 minutes, until barely golden on top and bottom. Resist over baking, they will come out dry and not as tasty. Cook on racks.
