In a large bowl, whisk together almond milk, evaporated milk, protein powder, vanilla extract, honey, orange zest, and cinnamon until smooth.
Add the rolled oats and stir well. The mixture will look thin - it thickens significantly overnight.
Divide evenly between 4 jars or airtight containers.
Top each jar with ½ cup cubed papaya, a squeeze of fresh lime, and a small piece of lime peel.
Cover and refrigerate at least 6 hours or overnight.
In the morning, stir and add a splash of almond milk if too thick. Dust with extra cinnamon and serve cold.
