Big round cakes have one tricky spot: the center. This Cake Heating Core is the bakery-style helper that brings heat right where large and deep cakes need it most, helping the middle bake at the same pace as the edges for a more consistent finish. Set it in the center of any 12-inch or larger round pan before pouring in your batter, then bake as usual. It’s a smart pick for celebration tiers, extra-tall layers, and any recipe that tends to dome or lag in the middle, especially when you’re chasing clean, level layers for stacking and decorating. Great For 12-inch and larger round cakes, deep cakes, tall celebration layers, tiered cakes, and recipes that bake slower in the center. Features Aluminum heating core designed to promote more even baking in large or deep round cakes Use with any 12-inch or larger round cake pan Size: 3.5 in diameter x 4 in high (8.8 cm x 10.1 cm) Material: Aluminum Made in USA Care: Hand wash in warm, soapy water; do not put in dishwasher
