Step 1: Preheat the oven to 350ºF. Line two 9x5-inch loaf pans with parchment paper or foil to cover the bottoms and up the sides with at least a 1-inch overhang. Spray lightly with nonstick cooking spray.
Step 2: Cream the butter and sugar together in the bowl of an electric mixer until light and creamy, about 5 minutes. Add in the eggs, one at a time, scraping down the sides of the bowl after each addition.
Step 3: Meanwhile, in a medium bowl, sift together the flour, cocoa powder, cinnamon, salt, baking powder and baking soda. In another bowl or liquid mixing cup, combine the buttermilk, coffee and vanilla.
Step 4: With the mixer on low, add 1/3 of the dry ingredients, followed by half of the buttermilk mixture, beating just until combined. Add another 1/3 of the dry ingredients, then the remaining buttermilk, followed by the remaining dry ingredients.
Step 5: Divide the mixture between the two prepared loaf pans. Shake the pans back and forth to even the tops. Sprinkle 1/3 cup of the chocolate chips over the top of each pan, then using a knife, "cut" the chips through the batter.
Step 6: Bake until a toothpick inserted in the center of the bread comes out clean, 45-55 minutes.
Step 7: Let the bread cool completely before lifting out of the pans.
