How to store these Crumbl peanut butter bar cookies?
Since this is a cookie recipe that is served chilled, you can store them in an airtight container in the fridge for up to 5 days.

Yes 🙂 I would recommend flash-freezing these cookies on a flat baking sheet until fully solid. Transfer the cookies to an airtight container making sure to separate the cookies with wax or parchment paper and freeze for up to 2 months.
Do I have to make the chocolate frosting from scratch?
I highly recommend making the cream cheese chocolate fudge frosting from scratch because homemade is always best.
But if you would rather use store-bought, I love the Simple Mills frosting. It states the best out of all the store-bought ones I purchased.
