Preparation
Line an 8x8 inch (20x20 cm) pan with parchment paper, leaving an overhang on the sides to lift the bars out easily.
In a medium bowl, combine the 1 cup (240 ml) of almond butter, melted coconut oil, almond milk, and liquid Stevia.
Whisk until the mixture is completely smooth and well combined.
Pour the almond butter mixture into the prepared pan and spread it into an even layer.
Place the pan in the refrigerator to set for at least 3 hours, or until firm to the touch.
Once the base is firm, prepare the topping.
In a small bowl, whisk together the cocoa powder, 2 tablespoons (30 ml / 1 fl oz) of almond butter, and granulated Stevia until a smooth sauce forms. If it's too thick, add a teaspoon of almond milk to reach a pourable consistency.
Pour the chocolate topping over the chilled almond butter base and spread evenly. Return to the refrigerator for 15 minutes to set the topping.
Using the parchment paper handles, lift the block from the pan.
Cut into 12 squares and serve.
Taste the batter before chilling and adjust the sweetener to your preference, as sweetness levels vary between brands.
