There are a gazillion of choices when it comes to cake pans. It’s worth investing in a good set but it’s easy to get carried away with all the different options.
I currently use only Fat-Daddio’s pans and have had great success with them the past couple of years. I have a set of (3) 6-inch diameter round cake pans and a set of 8-inch diameter round cake pans from this brand that are my always go to.
You don’t need to go with this brand, but I do recommend you go with shiny baking pans. Shiny baking pans reflect heat, allowing the cake the bake more evenly. Dark pans will cause the sides of the cake to darken.
