How to Use a Heating Core for Cakes

Large cakes, such as those for weddings and large celebrations, can be difficult to bake. By the time the center is fully cooked, the top has browned too much and the sides have dried out. Using a heating core solves that problem by distributing the oven's heat more evenly throughout the cake. It is made from a hollow metal tube that absorbs heat, then releases it into the center of the cake.

Step 1

Spray the heating core with nonstick spray when you prepare your cake pans as directed in your recipe.

Step 2

Pour the cake batter into the prepared cake pan.

Step 3

Insert the heating core into the center of the cake. The narrow opening of the heating core should rest on the bottom of the cake pan. The batter should fill the center of the heating core.

Step 4

Bake the cake for the same time and at the same temperature as you normally would.

Step 5

Insert a toothpick halfway between the side of the cake pan and the heating core near the end of the cooking time. If the cake is too thick for the toothpick to reach to the center, use a wooden skewer. If the toothpick or skewer comes out clean, the cake is done. Remove it from the oven and let it cool on a rack.

Step 6

Run a butter knife or offset spatula gently around the edges of the cake pan and the outside edges of the heating core when you are ready to remove the cake from the pan.

Step 7

Place a rack over the top of the cake pan and carefully flip the pan over onto the rack. The cake should fall onto the rack.

Step 8

Use your knife or offset spatula to remove the heating core from the cake. Remove the small cake plug from the inner area of the heating core. Set the plug aside.

Step 9

Cover the plug of cake with icing and insert it into the hole in the cake left by the heating core. Frost the cake as usual, covering the plug and making it unnoticeable.
