In a mason jar or an airtight container, combine the oats, protein powder, chia seeds, cinnamon, and a pinch of salt.
Add the almond milk, cashew butter, maple syrup, and vanilla extract to the dry mix.
Stir well to ensure all the ingredients are thoroughly combined.
Fold in the mini chocolate chips for that irresistible cookie dough appeal.
Seal the container and refrigerate overnight, or for at least 4 hours, to allow the oats to absorb the liquid and soften.
In the morning, stir the oats to combine. Add an extra splash of milk if needed for the desired consistency.
Top with additional chocolate chips or a drizzle of nut butter before serving, if desired.
