In a medium mixing bowl, combine almond flour, cashew butter, maple syrup, melted coconut oil, vanilla extract, and salt until a soft dough forms.
Fold in the chocolate chips until evenly distributed.
Line a cutting board or tray with parchment paper.
Transfer the dough onto the parchment and press firmly into an even rectangle about ½-inch thick.
In a microwave-safe bowl, combine the chocolate chips and coconut oil.
Microwave in 30-second intervals, stirring after each, until completely smooth.
Pour the melted chocolate over the cookie dough and spread evenly using a spatula.
Sprinkle with flaky sea salt if desired.
Freeze for about 10 minutes, or until the chocolate has hardened.
Break or slice the Healthy Cookie Dough Bark into large pieces and serve immediately or store for later.
