Hello everyone!I have MANY nordicware and wilton 3D cake pans and form pans and I always end up with the same issue. Outside crunchy, inside mushy. My cornucopia turns out fine but my christmas tree ends up having a charcoal burnt star. I have read that I need to lower the cooking temperature but different people say different things. Also, how much longer do I need to cook it for?I will be baking soon for Halloween (3D skull Red Velvet cake with cream cheese frosting).Any...
