Notes

Cool the Oat Cookie Base: This is a very important step in this recipe. You want to make sure that the oat cookie base is cooled completely before adding the remaining ingredients.
Make the Oat Cookie Crust Ahead of Time: If you want to save time, you can make the cookie base of these lemon blueberry bars ahead of time and store them in the refrigerator for up to 3 days. 
Whipping the Cream: It is important that you whip your whipping cream until you have formed some nice big and thick peaks. Once you have big and thick peaks, you have the perfect whipped cream topping.
