Half sheet cakes are a solid choice, but there is one thing to keep in mind: knowing how to serve them. Most people assume a typical box serves 50 person, which leads to guesswork about whether portions will be too big or too small for your guests. For instance, depending on whether you’re slicing into squares or rectangles, here is the number of servings per cut (see chart above). This matter because portion size changes based off the situation. How much cake do you think a guest at your wedding would eat compared to a guest at your officemate’s birthday? Smaller pieces pair better with larger buffet, so take note! Also worth noting: you can greatly increase your yield by shaving a little off each side of square. That flexibility is the whole point of choosing a half sheet in the first place.
Before you begin cutting, be aware of physical dimensions. A typical half sheet pan is eighteen by thirteen inches. When trimmed, it is usually closer to eighteen by twelve, which leave less space for baking. Those inches makes a big difference in how many guests will fit on each one. And what you’re buying is either a single two-inch layer of cake, or two layers plus filling (double), which is four inches high. The former is lighter, easier to cut through without smooshing the frosting; the latter make quite an impact on dessert table and also provides a much more different experience altogether from eating a two-inch thick piece of cake.
How to Cut and Serve Half Sheet Cake
When it comes to the actual cutting, technique save you from disaster. Because cold buttercream retains its form, chilling your cake for half an hour beforehand really do make a difference. Use a large serrated knife and clean it after each cut; your slices will be clean-cut rather than collapsed. To keep everything even (and to prevent the cake from shifting about while you’re cutting) I recommend cutting across the whole thing in horizontal rows first, followed by slicing the rows into separate portion. Though it might seem unnecessary, it’s professional-looking and fair to everyone involved.
Then there’s the serving strategy. Consider your audience! For instance, who’s going to eat all that crusty goodness? And what about the edges? They is loaded with frosting, which attracts kids and other enthusiastic diners. How about the middle, which contain plain ol’ cake that is equally delicious but lacks that sugary glaze? Serving from the center out will leave the crust distributed among all tasters. It is a seemingly minor detail, but something to keep in mind if you’d like everyone to feel as though they got a decent slice.
Lastly, think about how many people you’re feeding and plan accordingly. If you’re hosting a big wedding reception, tiny one-by-two inch slivers are perfectly adequate. People will be full after they sample a bite or two, and the little noshes makes for a sweet ending to dinner. On the flip side, if this is a family dinner and cake is the showpiece, go for the gusto with big old three-by-three-inch slabs. Look at the infographic below for some helpful guidance on occasion-appropriate sizing.
When in doubt: follow the instructions. No need to guess; you’ll thank yourself later. Remember: preparation is key, and planning the cut should of saved you loads of anxiety when it actually happens, and nobody wants to go home hungry, do we?
