1-First Step: Gather and Prep Ingredients: Set out a pint-sized mason jar. Soften cream cheese at room temperature for 10 minutes if needed. Rinse fresh blueberries or thaw frozen ones slightly. Crush the graham cracker sheet into fine crumbs using a zip bag and rolling pin. Melt butter in microwave for 10 seconds. This mise en place keeps things smooth.

2-Second Step: Mix the Cheesecake Base: Add ½ cup rolled oats, ½ cup milk, ¼ cup Greek yogurt, 2 tbsp softened cream cheese, 1 tbsp honey, and ½ tsp vanilla extract to the jar. Stir vigorously with a spoon for 30-45 seconds until creamy and no lumps remain. Taste and adjust honey if berries are tart. The mixture thickens as oats absorb liquid.

3-Third Step: Layer the Blueberries: Spoon ½ cup blueberries on top of the oat mixture. Gently press down without fully stirring for a pretty swirl effect in the morning. For a sauce layer, mash half the berries first and mix lightly into the base. Frozen berries release juices overnight, adding natural sweetness.

4-Fourth Step: Prepare and Add Crumble: Mix crushed graham cracker crumbs with 1 tsp melted butter in a small bowl until it clumps like wet sand. Sprinkle half the crumble over the blueberries. Save the rest in a tiny container or bag for morning freshness. This prevents sogginess.

5-Final Step: Chill, Serve, and Enjoy: Seal the jar tightly. Refrigerate for at least 4 hours, ideally overnight. In the morning, stir in remaining crumble. Eat cold straight from the jar or let sit 5 minutes to soften. Garnish with extra berries or lemon zest. Serves one; makes 1.5 cups total volume.
