Pour milk in a saucepan, and sift in the icing sugar and the corn starch.
Over low heat, slowly stir or whisk, letting the whisking rest every minute.
Once it reaches a custard stage (thickened but still pourable), stir in 1 capful of almond essence.
Continue stirring until the mixture thickens to a pudding consistency.
Once at pudding consistency, remove from the stove and let cool for 5-10 minutes.
Scoop into containers and place in the fridge to chill (1 hour).
Top with edible sprinkles before serving.
