Grease a large loaf pan with cooking spray (9” x 5”)
In a medium sized bowl, mix together sugar, baking soda, flour, and salt
In a large mixing bowl mix together the melted butter, hot coffee, and cocoa powder. Once mixed, add in the flour mixture. Whisk together until combined
Add in the eggs, vanilla and sour cream. Mix until evenly combined (if adding mini chocolate chips, mix in after this step)
Pour the batter into the greased loaf pan (top with standard sized chocolate chips if using) and bake for 50 minutes - 75 minutes or until a toothpick comes out clean
Note: This yields one large loaf, but depending on the size of the loaf pan you may have enough for 2 loaves (don't fill the loaf pan all the way - be sure to leave 1” of the loaf pan around the edges without batter)
Remove from the oven and cool. After 15 minutes, run a knife along the sides of the loaf and flip onto a wire rack to finish cooling
Notes
For extra melted chocolate on top, you can scatter more chocolate chips on top when it comes out of the oven.
