No longer relegated to lunchbox sandwich fare, the sweet-and-salty combination of peanut butter and jelly makes a tasty breakfast and snack muffin, too.
Don't over mix the batter, stir just until the dry ingredients are combined for tender muffins.
Grease only the bottom of muffin cups; muffins have better shape when sides are not greased.
Choose shiny pans to give muffins a delicately browned and tender crust.
Always serve muffins piping hot!
