As a Fat Daddio’s exclusive retailer, Mangelsen’s offers a large variety of great Fat Daddio’s baking products! The heating core rod measures 4.5″ in length.
From Fat Daddio’s website: “The ultimate time saver! Stop gooey centers with a heating rod. A heating rod is recommended by professionals for use on cakes that exceed 9″ in diameter or are 3″ or 4″ deep. Use one or more heating rods to improve baking results with deeper, larger and novelty-shaped cake pans.”
