  • Mix in the sour cream and milk. Don’t worry if the batter looks a little curdled at this stage; that's perfectly normal!

  • Gradually add the dry ingredients to the wet ingredients. Mix on low speed only until the flour is just incorporated. Be careful not to overmix the batter; a few lumps are okay. Overmixing can lead to tough muffins.

  • Divide the batter evenly among the prepared muffin cups, filling each one about three-quarters full. If you like, sprinkle a few extra chocolate chips on top of each muffin.
