Divvying up a round cake at a large party is no easy feat. Slice too thin, and the delicate piece of cake will fold over on itself as you transfer it to the plate. Cut too large, and half the guests will be left cake-less.
Luckily, we’ve stumbled across a genius solution. Earlier this month, Australian baker Katherine Sabbath posted a cake slicing video on her Instagram account that has the Internet going wild (it’s already been viewed 1.2 million times). Instead of cutting the layer cake into traditional triangles, Katherine slices the cake horizontally into one-inch thick slabs, and then cuts each slab into one-inch rectangular portions. She presses a plastic cutting board against the slab as she slices it to keep it steady as it separates from the cake. When cut completely, the cake yields at least 30 pieces.
Katherine calls the portions “responsible servings,” but reminds viewers they can always go back for seconds or thirds. That’s the brilliance behind this technique: it ensures everyone at the party will get a piece, and there’s sure to be leftovers for anyone who wants more.

The cake in the video is a chocolate mud cake filled with raspberries and a vanilla bean Swiss meringue buttercream—yum! But you can achieve this look at home with any flavor layer cake you prefer. To do so, bake two 8 or 9-inch round cakes and allow them to cool completely. (If you have time, chill them in the fridge after they’ve cooled to room temperature, which will make them easier to cut). Then, carefully slice them in half horizontally using a serrated knife, keeping one hand on the top of the cake to steady it. Once you have four even layers, you can stack and frost the cake as usual. Refrigerating the fully frosted cake will firm it up and make it much easier to slice, as will using a longer knife. Prepare to watch your friends be amazed!
