In a large bowl, whisk the flour, cocoa powder, baking soda, and salt together until combined. Mix in 3/4 cup chocolate chips. Set aside.

Using a handheld or stand mixer fitted with a paddle or whisk attachment, beat the butter and sugar together on high speed until smooth and creamy, about 2 minutes.

With the mixer running on medium speed, add the eggs one at a time, beating well after each addition. Then beat in the yogurt, mashed bananas, and vanilla extract until combined. Add the dry ingredients and hot water, and beat on low speed until combined. Batter is thick. Do not over-mix.

Pour and spread the batter into the prepared baking pan. Sprinkle remaining chocolate chips on top. Bake for 60-65 minutes, covering with foil halfway through. Bread is done when a toothpick comes out clean with only a few moist crumbs.

Remove from oven and cool in the pan on a wire rack for 1-2 hours before removing and slicing.
