In a large mixing bowl, combine rolled oats, milk, maple syrup, chia seeds, instant coffee, vanilla extract, and a pinch of salt. Blend until well incorporated.

Cover the bowl tightly and refrigerate for at least 4 hours, preferably overnight, until thickened.

In another bowl, whisk together vanilla Greek yogurt, softened cream cheese, and optional maple syrup until smooth.

Retrieve the oats and divide evenly among four mason jars, layering with the yogurt topping.

Dust with cocoa powder for decoration, serve immediately or chill for a refreshing treat.
