Tips for baking the perfect muffins.

  • Don’t overwork the batter, unless the recipe like this one has a step for creaming ingredients together, stir them by hand. Overworked muffins do not rise as well and can be tough.
  • Do not full the muffin tin all the way to the top with batter. Three-fourth full is usually perfect.
  • A 4-ounce ice cream scoop or a 1/4 measuring cup is the perfect amount for a standard size muffin tin.
