Preheat the oven to 325 degrees. Grease a 9 inch loaf pan.
Using a stand mixer, beat butter and sugar for 5 minutes or until fluffy.
Slowly, add in eggs, egg yolks, banana, almond or vanilla extract. Beat until incorporated, about 3 minutes.
Add in flour, a little at a time. Beat on low, until batter is combined.
Fold in chocolate chips.
Spread batter into the prepared loaf pan and bake for 45-60 minutes or until a toothpick inserted comes out clean.
Cool for 20 minutes and then remove from the pan.
