Preheat a pan over low heat.
Stack two slices of bread on top of each other and place them in the pan.
Pour one carton of banana milk and add 1.5 tablespoons of butter into the pan.
Allow it to cook until the bottom of the bread turns a beautiful golden brown.
Flip the bread and continue cooking until both sides are evenly golden brown.
Transfer the milk toast onto a plate and drizzle with condensed milk.
