How many slices in a cake is one of those things you don’t really think about. Not until you are standing there, the cutter in hand, counting the number of servings and the number of guests so that everyone gets a slice. Then of course you might have to deal with those folks that want a generous portion, or a smaller cake slice. Or pretend to want a small slice and really want a big one. 

That is when it helps to have an idea of how to approach cutting the cake. But just to take any guesswork out of the equation, there is a printable guide in this post to make it a no-brainer.

How to cut different shapes and sizes of cakes

Back in the day, at weddings, it seemed that the aunts were always the ones to cut the cake. I will admit that I got really nervous when my nieces and nephews started getting married! The thought of having to cut someone’s wedding cake into the right serving size so everyone got a slice of cake that wanted one, was a little daunting. Thank goodness it seemed I was always given a different role at their weddings. Whew!

Figuring out how to cut the cake

Of course, the first consideration is what size cake needs cutting? Is it a round, square, or rectangular cake? Depending on the size of the cake, there are basic strategies for getting reasonably even-sized slices. Because, no matter the number of slices in a cake, making even-sized cuts is best. That is the fairest way to go!

With a small round 6″ diameter cake, one slice across the middle, then two more slices to divide each side into thirds, results in 6 even slices of cake. But the bigger the cake, the more slices to make, which is where my printable guide comes in super handy! (And it works for cutting pies too of course)


Basic tips for getting even slices in a cake

Getting great cake slices depends upon the cake to cut. Is it an angel food cake or a wedding cake? Is it a frosted or naked cake? Is it a layer cake with a large number of cake layers, or a sheet cake?

  • Use the right knife or cake cutter for the job. A long thin knife if best for cakes with frosting, but a serrated knife, like a tomato knife, is better for cakes without frosting, like angel food cakes and coffee cakes.
  • Measure your cuts first by just running a light scoring style cut across the top of the cake. Not too deep a cut, just enough to set your guidelines for the full cuts. 
  • Be gentle and patient. You don’t need to hack at it. Just run the blade across with a smooth, firm stroke. Cut slowly to avoid pulling away chunks so you get clean and consistent-looking slices.
  • With dense cakes like cheesecake or a chocolate ganache, heat the blade first. You can run it under hot water for a minute first, then dry it quickly and make your cuts.
  • It is tempting to cut with the cake serving spatula, and some are made for cutting too, but using a knife works much better. 
  • If your knife has a bunch of frosting on it then wipe it with a paper towel between cuts. That helps keep it looking tidy… And makes sure no one gets more or less frosting on their piece. We all know where that can lead!
