Follow these straightforward steps to create your own batch of Triple Chocolate Muffins:

1. Preheat the Oven: Set your oven to 350°F (175°C) and line a muffin pan with paper liners or grease it lightly.

2. Combine Dry Ingredients: In a large mixing bowl, whisk together the flour, cocoa powder, sugar, baking soda, baking powder, and salt until well combined.

3. Mix Wet Ingredients: In another bowl, combine the melted butter, sour cream, eggs, and vanilla extract. Whisk until smooth.

4. Combine Mixtures: Pour the wet ingredients into the dry ingredients and mix until just combined. Be careful not to over-mix; small lumps are okay.

5. Add Chocolate: Gently fold in the semi-sweet and white chocolate chips until evenly distributed throughout the batter.

6. Fill Muffin Cups: Spoon the batter into the prepared muffin cups, filling each about two-thirds full. If desired, add extra chocolate chunks on top for a decadent touch.

7. Bake: Place the muffin pan in the oven and bake for 20-25 minutes, or until a toothpick inserted in the center comes out clean.

8. Cool: Once baked, allow the muffins to cool in the pan for 5-10 minutes before transferring to a wire rack to cool completely.

These steps will help you create delightful muffins that will make everyone swoon!
