Whole milk creates creamier powder, but low-fat or skim milk work too.
Gently heat milk in a saucepan, stirring often, until it just boils.
Patience is key! Simmer and stir for hours until significantly thickened.
Lay the thickened milk on a cheesecloth-lined tray for air drying.
Let it dry naturally (1+ day) or use a food dehydrator for speed.
Break the dried milk into pieces, then blend for a finer powder.
Keep your homemade magic in an airtight container, cool and dry, for long-lasting enjoyment.
