Blend cookies in a food processor or blender until they resemble rough cornmeal. You can add the cream directly into the food processor or blender if you prefer, or move to a bowl and use a spatula or hand mixer to blend. Mix the 2 well.
Now, scoop your mixture onto a parchment-lined baking sheet. You don't have to use parchment, but it is so much easier to clean up after if you do. I used my small size OXO scoop with about 2 teaspoons. If you want your truffles a little bigger, you can go for 1 tablespoon.
Roll them in your hands until the balls are smooth.
Place in the fridge for about an hour until they are set.
Place your white chocolate chips in a microwave-safe bowl with the coconut oil. Keep in mind white chocolate can burn easily, so don't walk away during this step. I set it for 20-30 second intervals to melt. Mix between each one. Depending on how high your microwave is, this time is a variable. Also, note the chocolate does not need to be completely melted in the microwave. You will want it to be about 80% melted. Then remove from the microwave and mix until it is smooth.
Begin dipping the truffles one by one, coating them in melted chocolate. With a fork, lift the truffles out and tap to remove excess. Place back on the parchment-lined tray. Immediateley top with your sprinkles. The truffles are chilled, so the chocolate will harden pretty quickly. If it does set before you get the sprinkles on, simply dot a touch of chocolate to the top and add the sprinkles.
Once all the truffles are dipped, place them back in the fridge to set. With any excess chocolate you have, you can always mix in some nuts and dried fruit. Then drop by spoonfuls on a parchment sheet. Allow setting.
I found the truffles are best within 3- 5 days. Keep them stored in the fridge in an airtight container.
