Mix almond flour, protein powder, coconut flour, cinnamon, and sea salt. Add melted coconut oil, almond butter, maple syrup, and vanilla; stir into a soft dough.
Press dough into an 8x8-inch pan lined with parchment; freeze while preparing the date layer.
Blend dates, maple syrup, almond butter, vanilla, sea salt, and almond milk until smooth; spread over the base.
Melt chocolate and coconut oil; pour over the date layer and spread evenly. Freeze for 2-4 hours.
Sprinkle with flaky sea salt, then slice into bars. Store in fridge or freezer as desired.
Notes
Keep the bars refrigerated for a soft texture or frozen for a firmer bite.
