In a small bowl, stir together the softened cream cheese and 1 1/2 tablespoons of strawberry jam until smooth and creamy. Divide the mixture between two cups, and spread into an even layer.: The bowl will smell faintly of sweet strawberry as the jam loosens the cream cheese . Use a small spatula to fold until the mixture is glossy and free of lumps, which should take about one to two minutes by hand. You want a spreadable texture, so if it feels too stiff, add a tiny pinch of milk and mix until silky. This step matters because a smooth cheesecake layer clings to the fruit and jars without breaking apart. A common mistake is mixing too briefly, leaving bits of cold cream cheese that create an uneven layer.
Divide the sliced strawberries on top of the cheesecake layer. Then, layer 2 tablespoons of Greek yogurt into each cup (so you use a total of 1/4 cup of yogurt).: As you spoon the cheesecake mixture into each cup, press it gently so it forms a thin, even sheet across the bottom. Visually, you want a uniform pale pink or off white base, depending on how much jam is incorporated. This even layer anchors the toppings and prevents the oat mixture from seeping through. If you skip smoothing, the cheesecake layer can clump and make the jar lopsided when you add other components.
In a medium bowl, stir together the remaining 1/4 cup of Greek yogurt, oats, and milk until creamy and well mixed. Divide between both cups, then seal with a lid and place into the refrigerator overnight.: Layer the sliced strawberries so they cover the cheesecake spread without overcrowding. You should see vibrant red circles pressed gently into the cream layer. The fruit adds a fresh, slightly acidic note and a juicy burst when you bite into it. Avoid piling too many strawberries, as overpacking can push the cheesecake layer out of place and create excess juice that softens the oats overnight.
In the morning, top each cup with 1/2 tablespoon of the remaining strawberry jam, mix together, and enjoy.: Dolloping the vanilla Greek yogurt over the berries cushions the fruit and introduces tang mid jar. The yogurt should look glossy and hold a soft peak when placed. This add helps bridge the cheesecake and oats layers so the flavors meld overnight. If the yogurt is watery, it may seep and blur the layers, so choose a thicker variety for best results.
In a medium bowl, stir together the remaining 1/4 cup of Greek yogurt oats and milk until creamy and well mixed: The combined mixture should appear smooth and slightly thickened as the oats hydrate. Stir thoroughly until there are no dry pockets of oats , and the color is even. The aroma will be mild dairy with a hint of grain from the oats. This blend is the heart of the jar because it softens to a spoonable consistency that binds the whole dessert like breakfast. A typical error is under mixing which leaves lumps of dry oats that will stay chalky in the morning.
Divide between both cups then seal with a lid and place into the refrigerator overnight: Pour the oat mixture gently so it settles on top of the yogurt and berries, creating a distinct third layer. As the jars chill, you will notice the oats expand and the texture become creamy to the touch. Refrigerating overnight allows flavors to marry and textures to relax into a cohesive bite. If you open the jars too early, the oats may still be a bit chewy; patience yields the best result.
In the morning top each cup with 1/2 tablespoon of the remaining strawberry jam mix together and enjoy: When you remove the jars, the top will glisten and the scent of strawberry will be prominent. Spoon the jam over the surface and stir if you like an even swirl, or leave it layered for a pretty finish. Take note of the texture, it should be creamy with soft fruit pockets and a slightly toothy oat body. A common pitfall is adding too much jam at the end which can make the jar overly sweet, so taste before adding more.
