Making toast is a chemical reaction because you can't change it back into untoasted bread.
The drying of the bread is physical but the actual caramelization or darkening of the outer bread layer is a chemical change. The outer edges of the bread are beginning to char. Generally, a color change is an indicator of a chemical change.

Is butter melting on toast a chemical or a physical change?
it is a physical change
Is toast browning a chemical or physical?
It is a chemical change. Look at the explanation below the picture of the rusting nail. With toast a new substance has been formed due to the heat which caused the chemical change.
What are the differences between the physical and chemical?
in changes. Physical changes can be reversed. E.g. if you were to melt a block of ice, and then freeze it again, it would to some degree be reversed. This is a physical change. However, if you were to burn a peace of toast, the change would be chemical. Once the toast is burnt you cant get it back.
Is iron rusting a chemical or physical change?
Iron rusting is a chemical change: oxidation of the metal by oxygen in the air or water. When iron 'rusts' it oxidises. This is a chemical change, a physical change is when a molecule changes state, for example iron melting and going from a solid to a liquid.

Is burning toast a chemical change or a physical change how do you know?
It is kind of both....The chemical: The toast loses its water molecules and so loses most of its H2O.The Physical: The toast becomes hard and crunchy from soft and airy.Added:The toast burning is a total physical change, not chemical. Water loss from the toast is not a chemical change as species have not changed partners ( atoms have not rearranged into new species ) and H2O remains the molecule H2O, water.

Burning toast would be a chemical change. The bread would be changed into carbon and the reaction can not be reversed.
