Repeat the process of marking the middle of your cake until you've gone all the way around. Take a long piece of dental floss and wrap it around the circumference of your cake. Align the dental floss so that it's sitting right on the toothpicks if you're looking at the cake from above. Cross the dental floss where it meets and start pulling the ends of floss away from each other as though you were strangling the cake. Once the cut is complete, pull the floss out gently and discard it. Pull out all the toothpicks and continue preparing your cake."
Let's assume that your cake is 2 inches (5cm) high. In this case, you would insert the toothpick 1 inch (2.5cm) from the bottom of the cake. Make sure to insert the toothpick half-way into the cake so that there is still half sticking out of the cake. It's useful to continue using a ruler as a guide. A good rule of thumb is to insert a toothpick every 2 inches (5cm) apart. You'll want a piece long enough so that after it wraps around your cake, you still have some to hold in your hands. This motion will neatly slice the cake in half.
