Preheat the Oven
Preheat your oven to 375°F (190°C). Line a muffin tin with paper liners or lightly grease it. Trust me—stuck muffins ruin the mood.
Mix the Dry Ingredients
In a large bowl, whisk together flour, cocoa powder, sugar, brown sugar, baking powder, baking soda, and salt. Make sure everything is evenly combined so the muffins bake properly.
Combine the Wet Ingredients
In another bowl, whisk together eggs, milk, oil, and vanilla extract. Stir until smooth and slightly glossy.
Mix the Batter
Pour the wet ingredients into the dry ingredients. Stir gently until just combined. The batter should be thick but smooth.
Important: Do not overmix. A few small lumps are perfectly fine.
Add the Chocolate Chips
Fold in most of the chocolate chips. Save a few to sprinkle on top for that bakery-style look.
Fill the Muffin Tin
Scoop the batter into the muffin cups, filling each about ¾ full.
Bake
Bake for 18–22 minutes, or until a toothpick inserted into the center comes out mostly clean.
Cool Slightly (If You Can Wait)
Let the muffins cool for about 5 minutes before removing them. Then enjoy while warm for peak chocolate happiness.
