Creating custard oatmeal is a breeze if you follow these simple steps:

1. Prep the Oats: In a medium saucepan, combine the rolled oats, milk, and salt. Bring to a boil over medium heat.
2. Cook Oats: Reduce the heat and simmer, stirring occasionally, for about 5 minutes or until the oats reach your desired consistency.
3. Whisk Eggs: In a mixing bowl, whisk together the eggs, sugar, vanilla extract, and cinnamon (if using).
4. Combine Mixtures: Gradually stir the egg mixture into the cooked oats, ensuring to mix well to avoid cooking the eggs too quickly.
5. Cook Further: Continue cooking the mixture on low heat, stirring constantly for about 5-7 minutes, until it thickens into a custard-like consistency.
6. Adjust Sweetness: Taste the mixture and adjust the sweetness by adding more sugar if desired.
7. Serve Warm: Once done, remove from heat and portion into bowls.
