If you need to cut cake layers in half, there is a simple and accurate method that doesn't involve messing with knives or having your cake roll across the countertop.You can slice the cake in half with floss and toothpicks.
Step 1: toothpicks should be placed at the halfway point of the cake layer.
Step 2: Align floss around toothpicks.
To give the floss something to bite into, you should make a few cuts with a knife along the toothpick row.
Step 3: Cross the ends of the floss and hold them in each hand when the cake is fully wrapped.
As the circle of floss tightens, pull each end out and away from the cake.The floss needs to be moved slightly from side to side.
Step 4: You have two layers of cake.
Step 5: Lift off the top layer by moving a piece of cardboard or a baking sheet between the two layers.
