Preheat your oven to 350 degrees Fahrenheit. It’s important to have your oven ready so the bread bakes evenly. Prepare a 9×5 bread pan by spraying it with cooking spray, ensuring that your bread won’t stick.
In a large bowl, whisk together the dutch process cocoa, all purpose flour, dark brown sugar, granulated sugar, baking powder, baking soda, and salt. Whisking these dry ingredients together is essential for uniform distribution of the leavening agents and flavors.
Add the buttermilk, eggs, vegetable oil, and vanilla extract to the dry mixture. Combine these ingredients until you have a smooth batter. Be careful not to overmix; you want it to be just combined.
Gently fold in ½ cup of the semi sweet chocolate chips. This is where the fun begins—seeing those chocolate morsels mix in with your batter! They’ll melt beautifully while baking.
Pour the batter into your prepared bread pan, spreading it out evenly. Top the batter with the remaining ¼ cup of chocolate chips to create a gooey chocolate top.
Place the pan in the oven and bake for 55 to 60 minutes. You’ll know it’s ready when a toothpick inserted into the center comes out clean. The aroma will fill your kitchen as it bakes.
Once baked, remove it from the oven and let it cool in the pan for about 10 minutes. This will make it easier to remove without breaking.
After cooling, transfer the bread onto a wire rack to cool completely. This step is crucial as it prevents the bottom from getting soggy.
Once cooled, slice the bread and enjoy warm, or store it for later. The texture and flavor develop beautifully as it sits.
