Creating the Best Death by Chocolate Muffins is a breeze with these simple steps:

1. Preheat Oven: Preheat your oven to 350°F (175°C). Line a muffin tin with paper liners or grease it lightly.
2. Mix Dry Ingredients: In a large bowl, sift together the flour, sugar, cocoa powder, baking soda, baking powder, and salt.
3. Combine Wet Ingredients: In a separate bowl, whisk together the vegetable oil, egg, vanilla extract, and buttermilk until well combined.
4. Combine Mixtures: Gradually add the wet ingredients to the dry ingredients. Stir until just combined, being careful not to overmix.
5. Add Chocolate Chips: Fold in the semi-sweet chocolate chips, ensuring even distribution throughout the batter.
6. Fill Muffin Cups: Divide the batter evenly among the muffin cups, filling each about two-thirds full.
7. Bake: Place the muffin tin in the preheated oven and bake for 20-25 minutes, or until a toothpick inserted in the center comes out clean.
8. Cool: Remove from the oven and allow the muffins to cool in the tin for 10 minutes, then transfer to a wire rack to cool completely.

These steps will guide you effortlessly to create muffins that are truly the epitome of chocolate bliss.
