Add 1 tablespoon of apple cider vinegar to a 1 cup measuring cup. Fill the cup up the rest of the way with non-dairy milk and set the milk aside to curdle and turn into buttermilk.
Divide the batter among the 12 muffin cups. Top each muffin with more chocolate chips if desired.
Bake the muffins for about 18 minutes or until a toothpick inserted into the center comes out clean.
Allow the muffins to cool for a few minutes before serving.
Notes
- Allow the muffins to cool completely before eating them. This makes them fluffier!- Store any leftovers in an airtight container in the fridge for about 1 week.
