Bakery-Style Chocolate Muffins

0 Preheat your oven to 375°F (190°C). Line a muffin tin with paper liners or lightly grease the cups.
1 In a bowl, whisk together the flour, cocoa powder, baking powder, baking soda, salt, and granulated sugar until well combined.
2 In another bowl, whisk together the eggs, buttermilk, vegetable oil or melted butter, and vanilla extract until smooth and well combined.
3 Pour the wet ingredients into the bowl of dry ingredients. Use a spatula or wooden spoon to gently fold the mixtures together until just combined. Remember, a few lumps are perfectly fine; overmixing can affect the muffin's texture.
4 Gently fold in the chocolate chips into the batter, ensuring an even distribution of chocolatey goodness.
5 Spoon the batter into the prepared muffin cups, filling each about 3/4 full.
6 Place the muffin tin in the preheated oven and bake for 18-20 minutes or until a toothpick inserted into the center of a muffin comes out clean
7 Once done, remove the muffin tin from the oven and let the muffins cool in the tin for a few minutes before transferring them to a wire rack to cool completely.
