Preheat the oven to 340°F (170°C). Line a loaf pan with parchment paper or grease it well with oil or butter.
In a large mixing bowl, mash 2 large ripe bananas until completely smooth.
Add in 120 grams 5% fat plain Greek yogurt, 1 Tablespoon honey, 2 eggs, beaten, 1/2 teaspoon vanilla extract,1/2 teaspoon ground cinnamon, and 1/4 teaspoon salt and whisk for 2 minutes or until smooth and creamy.
In a separate bowl, stir together the 150 grams Gluten-free almond flour, 80 grams vegan vanilla flavored protein powder, and 2 teaspoons baking powder.
Gently fold the dry ingredients into the wet ingredients using a spatula. Stir just until combined—don’t over-mix.
If using, fold in the 3/4 cup unsweetened chocolate chips.
Pour the batter into the prepared loaf pan and spread evenly.
Bake for 25 to 40 minutes or until a toothpick inserted into the center comes out clean. If the top is browning too quickly, tent the loaf with aluminum foil.
Remove from the oven and let cool in the pan for at least 15 minutes before slicing and serving.
