Combine milk, PB Fit, protein powder, and salt in a Beast Blender and pulse for 5 seconds until perfectly smooth.

Place the oats in a mason jar or airtight container and pour the peanut butter milk over them.

Stir well with a silicone spatula to ensure every oat grain is hydrated.

Seal the container and refrigerate for at least 4 hours, though overnight is preferred for texture.

Before serving, top with the crushed Nutter Butter cookie and an optional peanut butter drizzle.
