Combine the base ingredients by mixing rolled oats, milk, yogurt, and chia seeds in a bowl. Whisk in honey, cardamom, cinnamon, turmeric, ginger, and a pinch of salt until creamy.

Refrigerate the mixture overnight or for at least 6 hours, covered tightly.

Before serving, stir the oats and add a splash of milk if too thick to reach desired consistency.

Scoop into bowls and top with chopped nuts and dried mango or raisins before enjoying.
