1. Preheat the oven to 350 degrees Fahrenheit (175 degrees Celsius).
2. In a mixer fitted with the whisk attachment, beat the egg whites. When soft peaks form, add in the sugar slowly and beat until stiff. Add egg yolks, maple syrup and extract, dissolved espresso, one and 3/4 cups flour, oil, milk, and baking powder, mixing between each addition.
3. Mix the chocolate chips with the remaining tablespoon of flour.
4. Spray a Bundt pan very well with cooking spray and pour in some of the batter. Sprinkle some of the chocolate chips, then alternate batter with chocolate chips until both are complete. (This method will prevent the chocolate chips from sinking to the bottom.)
5. Bake for one hour.
