In a large mixing bowl, combine rolled oats, chia seeds, Greek yogurt, heavy cream, milk, honey, and vanilla extract. Whisk until smooth and well-blended, approximately 1-2 minutes.

Dice fresh strawberries and reserve a handful for topping. Fold the diced strawberries into the oat mixture.

Distribute the creamy oat mixture into two jars or containers. Layer additional diced strawberries on top.

Cover the jars and refrigerate for at least 4 hours, preferably overnight.

In the morning, stir the oats well, top with reserved strawberries, and drizzle with extra honey or cream if desired.
