In a large bowl, combine 1 cup of rolled oats, 1 cup of Greek yogurt, 1 cup of milk, and 2 tablespoons of chia seeds. Add 3 tablespoons of peanut butter, 2 tablespoons of maple syrup, 1 teaspoon of vanilla extract, and a pinch of salt. Stir vigorously until all ingredients are well blended.

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

Once the oats have thickened, prepare jars or containers for serving. Spoon about one-third of the oat mixture into each jar, then add 2 tablespoons of jam on top.

Top the jars with more oat mixture until nearly full, adding another dollop of jam and optional toppings like berries or chopped peanuts.
