1-1/2cupabout 6 ounces chocolate chip morsels (I use a mix of milk and semi-sweet in a 50:50 ratio)
Preheat oven to 350 degrees.
Mix the dry ingredients: In a bowl, whisk together both flours, salt, cornstarch, and baking soda.
Mix the wet ingredients: Set up an electric mixer with the paddle attachment. Add mashed bananas followed by both sugars. Beat on medium speed until well mixed. Stop and scrape as needed. Reduce speed to low; add the yogurt and beat till they are combined. Add vanilla and mix well. [ Note - You don't need an electric mixer. You could combine the ingredients using a whisk ]
Mix the wet and dry ingredients: Add the flour mixture and mix until they are combined (don't overdo it - maybe for a minute). Add the chocolate chips and mix them for 15 seconds. You are ready to bake.
Get ready to bake: Line a cookie baking sheet with parchment paper; Use an ice-cream spoon to scoop cookie dough and place them around 2 inches apart on the baking sheet. Press them down with a back of a spoon to flatten them. Bake for 10-12 minutes until the cookies start to brown lightly around the edges (Ovens differ - so start checking on the cookies around 8 minutes)
Cooldown process: Remove the cookies from the oven; wait for a couple of minutes and then transfer to a wire rack and let them cool completely (approximately 5-6 minutes) before you serve them.
