0.5cupbuttermilk (or substitute with milk + 1 teaspoon vinegar)
0.33cupvegetable oil
1teaspoonvanilla extract
1cupchocolate chips (mix of dark and milk chocolate)
0.5cupchopped walnuts or pecans (optional)
Instructions
Preheat your oven to 350°F (175°C) and line a muffin tin with paper liners or grease with non-stick spray.
In a mixing bowl, whisk together the flour, cocoa powder, baking powder, baking soda, and salt until well combined.
In a separate bowl, combine the granulated sugar, brown sugar, eggs, buttermilk, vegetable oil, and vanilla extract. Whisk until the mixture is smooth and the sugars are dissolved.
Gradually add the dry ingredients to the wet mixture, stirring until just combined. Be careful not to overmix; a few lumps are okay.
Fold in the chocolate chips and nuts (if using) until evenly distributed throughout the batter.
Spoon the batter into the prepared muffin tin, filling each cavity about 3/4 full.
Bake in the preheated oven for 18-20 minutes, or until a toothpick inserted into the center comes out clean.
Once baked, remove the muffins from the oven and allow them to cool in the pan for about 5 minutes before transferring them to a wire rack to cool completely.
Notes
Serve warm, dusted with powdered sugar or topped with melted chocolate.
