Add the peanuts, plain flour, and milk to a blender and blend until smooth and creamy.
Add the cup of water to a pot, the salt and the cinnamon stick or leaf (if you are using ground cinnamon, add later), and bring to a boil on medium heat.
Pour in the blended peanut and stir (whisk) continuously until the porridge start thicken.
Let the porridge cook for 10 to 15 minutes then add the vanilla and nutmeg
Sweeten to taste with the sugar and condensed milk
Notes
The plain flour can be replaced with oatmeal.
Though I used both sugar and condensed milk you can use just the sugar or just the condensed milk if you rather.
The type of milk you use is simply up to you. I used oat milk.
