Line a baking sheet with parchment paper and lay out 20 crackers salted side down.
To a large mixing bowl, add the peanut butter and powdered sugar. Mix together with a hand mixer on low-medium until smooth.
Use an offset spatula, or just a knife, to spread the peanut butter mixture evenly onto the 20 crackers and top with another cracker.
Add the chocolate chips and coconut oil to a microwave safe bowl and heat for 20 seconds, stir, repeating until melted and smooth. It should not take more than a minute.
Using a fork or a chocolate dipping tool, dip one cracker sandwich at a time into the melted chocolate, covering it completely, and letting any excess drip off. Return to the parchment paper and immediately top with sprinkles.
Repeat for the rest of the cookie sandwiches and then move the pan to the fridge to set.
