In a medium mixing bowl or jar, add rolled oats, milk, yogurt, a pinch of salt, and vanilla extract. Stir vigorously for about 30 seconds until all ingredients are well blended.

Gently fold in the crushed chocolate cookies into your oat mixture, using a spatula for even distribution.

Cover your bowl or jar with a lid and place it in the refrigerator. Let the mixture chill for at least 4 hours or ideally overnight.

In the morning, remove from the fridge and give it a good stir. Check consistency; add a splash of milk if it's too thick.

Customize your breakfast with additional crushed cookies, a dollop of whipped cream, or fruits.

Transfer into serving bowls or jars. Enjoy this nutrient-packed breakfast!
