How to Cut a Round Cake

May 31st, 2019 by Desiree Smith

The games have been played, the presents are unwrapped and now comes the best part of any party – dessert! However, if you’re the lucky one who’s been tasked with cutting the cake, it can be stressful to make sure your slices are cut evenly (especially when someone ‘just wants a sliver’)!

Well, we’re here to share our secret strategy. Whether your cake is 8 in. or 16 in., you can learn how to easily cut a round cake into uniform slices – great for appeasing frosting lovers and cake lovers alike!

This method works for round cakes 8 in. and larger. If your cake is 6 in. or smaller in diameter, simply slice into wedges and serve.

How to Cut a Round Cake

Starting about 2 inches from the outer edge of your cake, cut a round circle.

Slice outer circle into approximately 1½ in. pieces.


Continue this process of cutting 2 in. circles, then slicing those outer circles until a 6 in. cake remains.

Cut remaining cake into wedges (or smaller for those who just want a taste).

YIELD: 30-33 servings (featured cake was 10 inches in diameter)

Here are a few additional tips and tricks to make slicing and serving a piece of cake!:

  • For dense cakes, rinse your knife in hot water after each slice to prevent the knife from sticking or tearing up your cake (also a great trick for cutting cheesecake)
  • Use a serrated knife to cut fluffy cakes, like angel food or chiffon
  • If you’re cutting a frosted cake, wipe your knife after each cut for nice, clean slices
  • To make even slices, use bakers’ twine or unflavored dental floss to divide your cake into even sections
  • To avoid slipping, place your cake on a grip mat before cutting

    Umm, yeah if you only want your guests to barely taste the cake! Cut me a real piece of cake! I would need three of those measly servings!

  2. Thank you for the awesome tips and cutting cake. My only question is how do you make the initial circle in the middle and keep it perfectly round?

  3. Roxanne says:

    How did you cut the initial circle? What did you use to cut it so neatly?

  4. Thank you, this is brilliant.

    At our next meeting when we serve refreshments, we will certainly be trying this out.

    Once again,

    Many thanks

    Any tiles for cutting the circle bit. How do you get it so accurate? Do you use a template (e.g a side plate) I can see myself totally ballsing it up

  6. Barbara says:

    Your maths is wrong. The cake featured is clearly not an 8”. If you do cut an 8” leaving 2” from the edge, then you end up getting an inner cake of 4” (not 6” as you stated) therefore impossibile to be sliced in 12.
    As for the outer pieces, according to geometry if your circle has a diameter of 8”, you can divide it into maximum 12 segments of about 1” 1/2 . So clearly you are giving false info here.
    The method is great, but the pictures (and numbers stated) are totally misleading.

  7. Thank you Desiree. Indeed a helpful post, well written. Will try it for sure.

    I don’t care about numbers being correct!
    I’ve seen this before and it works! They used a small plate for initial circle! Works great!

    Oh for goodness sake! any person with common sense can see that it works! Are you truly going to bring a geometry set into the kitchen…??!! Any person can follow the easy directions and just look at the photos. It doesnt have to be accurate to within a fraction of an inch…….LOL

  10. jayne mcauliffe says:

    Me neither. It so obviously works….and will serve more pieces than how its normally sliced

    This is a really cool article (the animated gif of the cake being cut is great!). Cutting the outside layer so that you can serve more slices is ingenious. That way you don’t have to serve super narrow slices, or leave guests wanting.
