How do you prevent cakes from sticking on the bottom?

To prevent cakes from sticking on the bottom, you can use a few different techniques:

1. Greasing and flouring the pan: This is the most common method and involves applying a thin layer of butter or cooking spray to the bottom and sides of the pan, then dusting it with flour. The butter or cooking spray helps the cake release from the pan, while the flour prevents it from sticking.

2. Using parchment paper: Placing a round of parchment paper on the bottom of the pan before pouring in the batter can also help prevent sticking. Make sure to cut the parchment paper to the same size as the bottom of the pan so that it doesn't curl up during baking.

3. Letting the cake cool completely before removing it from the pan: Cakes that are still hot are more likely to stick to the pan, so it's important to let them cool completely before attempting to remove them.

4. Running a knife around the edges of the cake before removing it: Once the cake has cooled, you can use a sharp knife to run around the edges of the pan, separating the cake from the sides. This will help loosen the cake and make it easier to remove.

5. Using a cake release spray: There are also commercial cake release sprays available that can be sprayed into the pan before baking to help prevent sticking.
