Begin by gathering all your ingredients: rolled oats, milk, yogurt, and vanilla extract. In a medium bowl or jar, combine 1 cup of rolled oats, 1 cup of milk, ½ cup of yogurt, and 1 teaspoon of vanilla extract. Mix these together thoroughly for about 1 minute until well blended.

Next, stir in your sweetener and a pinch of salt. Blend well for another 30 seconds, ensuring everything is fully incorporated into the oat mixture.

Gently fold in ½ cup of crushed chocolate cookies into your mixture using a spatula to incorporate them without breaking too much.

Cover the jar or bowl with plastic wrap or a lid and refrigerate your concoction overnight, or for a minimum of 4 hours.

When ready to enjoy, stir the mixture well to combine and add any desired toppings before serving chilled.
