I need to make a 16x16 square cake but my oven is too small is it ok to put four 8x8 together to make it 16x16 and if I do is bettercream neede to keep them together. Thanks in advance
Yes, you can "glue" cakes together with frosting. If your edges are a little crispy and/or rough, you may want to cut a very thin slice off of at least the sides that come together to make the seam easier to ice over.
