Keep the tray in the middle rack of the oven and toast the cornflakes for 10 minutes.
Note – Toasting the cornflakes is optional but it deepens the flavors and makes the cereal milk really addictive.
Remove the tray from the oven and let the cornflakes cool completely.
Transfer the toasted cornflakes into a pitcher or a bowl.
Add milk and brown sugar and stir well.
Refrigerate the pitcher for 30 minutes for the flavors to steep.
Bring the pitcher out of the refrigerator and stir once again to dissolve the sugar.
Place a fine-mesh sieve over a large bowl or a pitcher.
Pour the milk through to separate the cereal from the milk. Press down on the cereal to squeeze out as much milk as possible. Discard the leftover cereal.
Check for sugar and add more if needed.
Store in a clean pitcher or glass milk jug, refrigerated, for up to 1 week.

Notes
Scale the recipe if making it for a crowd.Many kinds of cereal are available under different brands; choose your favorite one. My other favorites are crunch berries, fruit loops, bran flakes, etc.You can also use almond milk, soy milk, or other plant-based milk as a dairy-free option.
