Creating the Best Death by Chocolate Muffins is a fun and enjoyable process. Follow these simple steps to achieve mouth-watering results:

1. Preheat the Oven: Begin by preheating your oven to 350°F (175°C). This ensures the muffins cook evenly.

2. Prepare Muffin Tins: Line a 12-cup muffin pan with paper liners or lightly grease it with baking spray.

3. Combine Dry Ingredients: In a large bowl, whisk together the flour, cocoa powder, granulated sugar, brown sugar, baking powder, baking soda, and salt until well mixed.

4. Mix Wet Ingredients: In another bowl, combine the milk, vegetable oil, eggs, and vanilla extract. Whisk together until smooth.

5. Combine Mixtures: Gradually add the wet mixture to the dry ingredients. Stir gently until just combined. Be careful not to overmix—a few lumps are okay!

6. Fold in Chocolate Chips: Gently fold in the dark chocolate chips to create pockets of gooey chocolate in your muffins.

7. Fill Muffin Tins: Distribute the batter evenly among the muffin cups, filling each about two-thirds full to allow room for rising.

8. Bake: Place the muffin pan in the preheated oven and bake for 20-25 minutes, or until a toothpick inserted into the center comes out with moist crumbs (not wet batter).

9. Cool: Remove the muffins from the oven and allow them to cool in the pan for about 10-15 minutes before transferring to a wire rack.

10. Enjoy: Once cooled slightly, enjoy these scrumptious muffins warm, or store them for later!
