In a mason jar or medium bowl, whisk together the Greek yogurt, softened cream cheese, milk, maple syrup or honey, and vanilla extract until smooth.
Stir in the rolled oats and half of the diced strawberries until everything is evenly combined.
Cover and refrigerate for at least 4 hours, or overnight, until the oats are soft and creamy.
Stir the oats before serving and add a splash of milk if you prefer a thinner consistency.
Top with the remaining strawberries, crushed graham crackers, and any additional toppings of your choice. Serve chilled and enjoy!
