Ok, i am new at this, but whenever I bake large cakes ( 14" x 3" square or round ) the middle come out runny and I have to cut it out. What the heck am I doing wrong. It is sooooooo frustrating. HELP!!!!!!
You're simply not baking it long enough.
Others will tell you to use a heating core or a flower nail. I've been baking 50 years and have never used them.
Also, 3" is pretty thick for cake. It will take a LONG time to bake. I only bake 2" tall layers.
as leah said, you need to bake it until it's done. Here is a good referenc chart on APPROXIMATE length of time needed for baking. Since you're using 3" pans you'll need this chart. Notice that the larger pans are baked at a lower temperature since they bake longer, this prevents the outside of the cake from over baking while the middle bakes til done.
if you use 2" pans you'll need this chart
Sounds like maybe your oven is too hot, if you are taking them out afraid they are burning only to find the middle is runny....
