Prepare the crust: Preheat your oven to 350°F (175°C).
Mix the almond flour, cocoa powder, and erythritol in a bowl.
Add melted coconut oil and stir until crumbly.
Press the mixture into a lined baking dish and bake for 10-12 minutes.
While the crust bakes, combine nut butter, coconut oil, and almond milk in a saucepan over medium heat.
Add erythritol and stir until smooth and melted.
Pour the caramel over the baked crust and refrigerate to set.
Melt the sugar-free chocolate in a microwave or double boiler.
Spread chocolate over the chilled caramel layer and return to refrigerator.
Once fully set, cut into bars and enjoy your Keto Twix Bars.
