Preheat oven to 350F and line two 12 count muffin pans with 15 muffin liners. (One pan if filling liners to top).
In a medium bowl sift together flour, cocoa powder, baking powder, baking soda and
Salt. Add the sugar and chocolate chips and mix to incorporate.
In a separate bowl mix together the remaining wet ingredients then add them to the dry ingredients and mix just until combined.
Fill muffin liners 3/4 full and bake for 15-18 minutes or until a toothpick comes out clean from the center of the muffins.
