Preheat the oven to 325F and line an 8x8 inch pan with parchment paper. Mix the almond flour, softened butter, powdered erythritol, salt, and vanilla until a crumbly dough forms.Press firmly and evenly into the bottom of the pan. Bake for 14 to 16 minutes until golden around the edges. Let cool completely.
Make the caramel by melting the butter in a saucepan over medium heat. Add the brown erythritol and stir until dissolved, about 2 minutes. Pour in the heavy cream and cook, stirring constantly, for 4 to 5 minutes until the mixture thickens and darkens slightly.Remove from heat and stir in the almond butter, vanilla, and salt until smooth. Let cool for 5 minutes.
Pour the warm caramel over the cooled shortbread base and spread into an even layer. Refrigerate for at least 30 minutes until the caramel is firm.
Melt the dark chocolate and coconut oil together in a microwave-safe bowl in 30-second intervals, stirring between each, until smooth and glossy.
Pour the chocolate over the set caramel layer and tilt the pan to spread evenly. Sprinkle with flaky sea salt while the chocolate is still wet.
Refrigerate for at least 1 hour until the chocolate is completely set. Lift out using the parchment and slice into bars with a sharp edge. Let bars sit for 2 minutes at room temperature before serving for the best texture.
