Ateco's Cake Tester is an accurate way to test cakes, brownies, cheesecakes, and quick breads to ensure they are baked to perfection. This great addition to cake making and baking supplies probes the center of cakes to know that they are fully cooked. No more raw, undercooked cake centers. Unlike using a knife or fork for cake testing, the Cake Tester's narrow profile won't leave large holes behind that need to be filled or patched. It's longer than toothpicks to reach deeper into cakes for more accuracy than the toothpick test. Simply insert the metal stem into the cake's center. If it comes out clean, the cake is fully cooked. If raw batter clings to the stem, the cake needs more time to cook.
