Prepare the Crumb Mixture:

• In a large mixing bowl, add the cold butter and flour.
• Use your fingertips to gently rub the butter into the flour until the mixture resembles fine breadcrumbs.
• Lift your fingers above the bowl while rubbing to help aerate the mixture, ensuring a lighter texture.

Heat the Milk:

• Slowly bring the milk to a boil in a large saucepan over medium heat. Stir occasionally to prevent scorching.

Combine the Ingredients:

• Once the milk reaches a boil, gradually sprinkle in small handfuls of the flour mixture while whisking continuously.
• Keep whisking to prevent lumps from forming.

Simmer:

• Reduce the heat to low and let the mixture simmer for at least 5 minutes, stirring occasionally.
• The mixture will thicken into a smooth, porridge-like consistency.
  

Serve:

• Spoon into bowls and generously sprinkle with cinnamon and sugar.

Serve warm and enjoy!
