Preheat your oven to 350°F (175°C). Line two small loaf pans with parchment paper or grease them well.
Mix Dry Ingredients:
In a large bowl, whisk together the flour, sugar, cocoa powder, baking soda, baking powder, and salt.
Combine Wet Ingredients:
In another bowl, whisk the eggs, oil, vanilla extract, and buttermilk until smooth.
Combine Wet and Dry:
Gradually add the wet ingredients to the dry ingredients, mixing until just combined. Avoid overmixing.
Add Chocolate Chips (Optional):
Gently fold in the chocolate chips for an extra burst of chocolate.
Bake:
Pour the batter evenly into the prepared loaf pans. Bake for 35-40 minutes, or until a toothpick inserted into the center comes out clean.
Cool:
Allow the cakes to cool in the pans for 10 minutes, then transfer them to a wire rack to cool completely.
