In a large mixing bowl or a mason jar, combine 1 cup of rolled oats, 2 tablespoons of chia seeds, and 2 tablespoons of light brown sugar. Pour in 1 cup of your choice of milk and 1 cup of plain Greek yogurt or any dairy-free alternative. Add a pinch of lemon zest if desired.

Using a spoon or a whisk, stir the mixture vigorously for about 30 seconds, ensuring the oats are fully submerged in the liquid.

Gently fold in 1 cup of fresh or frozen raspberries into the oat mixture.

Cover the bowl or jar tightly with a lid or plastic wrap and place it in the refrigerator. Allow it to chill for at least 3 hours, but ideally overnight.

When you're ready to indulge, remove the jar from the fridge and give it a gentle stir. Add a splash of milk if the mixture seems too thick.

Before enjoying, enhance your dish with extra toppings like fresh raspberries and a dollop of whipped cream or a sprinkle of nuts.
