I am planning on doing 3 layers of cake and 2 layers of filling. Can anyone help me approximate? Thanks!!!!!!!!!!
i take it that it is a rectangle...
if you... are making it to seve 1 x 2 inch slices it gives you 75... (wilton's wedding sizes)
if you... are making it to serve 1.5 x 2 inch slices it gives you 50 ... (erlene's slices - or wilton's party size)
Well a 2 layer 11x15 is 60 servings according to wilton. 10x15 is an odd pan size. As pp says, just measure out since it is a square shape.
