How many boxes of cake mix would it take to make a 1/4 sheet cake? And a 1/2 sheet cake? Also, does anyone know how much longer it would take to bake a 1/2 sheet cake? Thanks!

I use 1 box for a quarter and 2 boxes for a half sheet cake. I bake the half about 35 minutes on 350 degrees and it works for me. thumbs_up.gif

1/4s and 1/2 sheets are different sizes to different people.
If you match the cake to the board & box sold as that size you will need:
1 cake mix for a 12x8; approx. 20 minutes at 325 degrees
2 mixes for a 11x15 ; approx. 30-40 minutes @ 325
2 1/2-3 for a 12x18; approx. 45-60 minutes @ 325
Each of those sizes is for a cake/pan 2" deep.

Time # are just a guide. You should bake them until you smell them, then test w/a toothpick or touch lightly w/you finger near the center; if it springs back any it is done. A well baked cake should not pull away from the edges of the pan. You should take it out before thaticon_smile.gif

Everything you ever wanted to know about baking, assembling and decorating your 1st tiered/stacked/layer or in your case sheet cakes:

Has everything from cake and frosting/fondant recipes to baking help and so much more.

FYI, there are links to Wilton's cake preparation charts which give batter requirements by pan size.

If you're only doing a single layer, you only need to bake once. If you're doing a layered sheet cake you'd need twice the amount of batter (have to fill two pans).

The WASC cake recipe made w/two DH white cake mixes yields a tad over 14 cups of batter which makes it perfect for larger tiers or sheet cakes. (Recipe is in above thread.)

I use 1 and 1/3 box per quarter sheet cake, so increase the wet ingredients by an additional 1/3 of what is required, also it takes 4 eggs.
