Double Chocolate Muffins are a moist muffin that is loaded with rich chocolate flavor.
Preheat oven to 375℉
In large bowl add vegetable oil, sugar, milk, eggs, vanilla extract, sour cream, flour, baking cocoa, baking soda, and salt.
Mix the ingredients with a hand mixer until all combined.
Fold in 2 cups of the chocoalte chips.
In prepared muffin tin fill the muffin cups 3/4 of the way full. I used cupcake liners for my muffin cups but you can spray the muffin cups with cooking spray.
With the remaining 1/2 cup of chocolate chips sprinkle tops of muffins with chocolate chips.
Place into the preheated 375℉ oven and bake for 18-20 minutes or until muffins are done. Or insert a toothpick into the center, if it comes out with a few slightly fudgy crumbs then they are done.
