Line an 8×8 or 9×9 baking dish with 2 strips of parchment paper, allowing paper to drape over edges. This will allow you to easily lift the bars out of the dish – without turning it into a hot mess.
In a large mixing bowl, add the first 7 ingredients, up to and including the Medjool Dates. Toss to incorporate. Set aside.
In a medium microwavable mixing bowl, add peanut butter, erythritol, maple syrup and vanilla extract. Microwave in 30-second increments, stirring each time – until the mixture is all incorporated and creamy.
Add peanut butter mixture to oat mixture, mixing until everything is incorporated. I used my hands – it’s easier.
Press mixture into the baking dish. Place in the fridge for about an hour.
Remove bars from dish, slice into bars or squares (your choice!). Store in airtight container in fridge.
