Although I used a SQUARE 10X10 because I only baked 6 at a time, you can use whatever pan you have but remember to allow plenty of room for them to more than DOUBLE in size! Don't crowd your buns people! You Will Need a 12X18" pan to bake them in, and line them up 3 on the short edge and 4 along the longer edge. Spray the pan generously with pan spray for easy release.
