In a medium mixing bowl, beat together the Greek yogurt, cashew butter, almond flour, honey, vanilla extract, and flaky sea salt with a hand mixer until completely smooth and creamy.
Fold in the mini chocolate chips until evenly distributed throughout the mixture.
Refrigerate the mixture for 20–30 minutes to firm it up, making it easier to scoop.
Line a baking sheet or large plate with parchment paper.
Using a small cookie scoop (about 1 tablespoon), scoop the mixture into bite-sized portions and roll into balls if needed. Place each bite onto the prepared baking sheet.
Freeze the cookie dough bites for at least 1 hour, or until completely firm.
Add the dark chocolate and coconut oil to a microwave-safe bowl. Microwave in 30-second intervals, at 50% power, stirring between each, until smooth and fully melted.
Working with only a few frozen bites at a time, dip each one into the melted chocolate using two forks. Allow the excess chocolate to drip off before returning the bite to the parchment-lined baking sheet.
If desired, sprinkle with flaky sea salt before the chocolate sets.
Freeze for an additional 15–20 minutes, or until the chocolate shell is completely hardened.
Transfer to an airtight freezer-safe container and store in the freezer until ready to enjoy.
