Method
- Preheat oven to 400 F. While oven is pre-heating, grease a muffin pan with some butter and lightly coat with flour.

- In a medium bowl, add the melted butter, vegetable oil, milk, eggs, sour cream, vanilla extract and sugar. Whisk together until combined.
- Add walnuts, the chocolate and the wet ingredient mixture to the dry ingredient and combine with a wooden spoon or spatula. Do not to over-mix.
- Fill each muffin mold up to 3/4 with a spoon. Cook in the 400F oven for 20 minutes or until a knife inserted in the middle of the muffin comes out clean.

Notes
TIP: Adding a small ramekin of water increases the humidity in the oven to keep the muffins nice and moist during the bake but this is optional.
