01 - In a medium bowl, combine rolled oats, almond milk, Greek yogurt, protein powder, cocoa powder, hazelnut butter, maple syrup, vanilla extract, and salt. Mix thoroughly until well combined.
02 - Divide the mixture evenly between two jars or containers, ensuring each portion has the same amount of oats and liquid.
03 - Cover and refrigerate overnight or for at least 4 hours to allow oats to soften and flavors to meld together.
04 - Before serving, stir the oats. Top each portion with chopped hazelnuts, dark chocolate, and a drizzle of hazelnut butter. Garnish with half a Ferrero Rocher chocolate if desired.
05 - Enjoy chilled for a quick, indulgent breakfast.
