Prepare Muffins:

  • Add wet ingredients to dry ingredients, then fold together with a spatula until just combined. Do not over mix.
  • Fill cupcake liners 2/3 full with batter. Do not overfill; you should have 16 muffins total.
  • Crumble crumb topping over muffins, gently pressing it into the batter.
  • Bake muffins for 15 to 20 minutes, or until a toothpick inserted in the center comes out clean. (Bake the muffins in batches, if needed.)
  • Let muffins cool for 10 to 15 minutes before serving.
