Line a tray or large plate (that will fit in your freezer!) with baking paper
Mix together the nut butter, maple syrup, vanilla, melted coconut oil and pinch salt until smooth
If you haven't already, make the oat flour by adding rolled oats to a blender and pulsing/blending until a fine flour forms
Add the oat flour and cocoa powder to the wet mixture, mix until thoroughly combined and a thick texture forms
Place the mixture onto your lined tray and press down until flattened - around 3/4cm thick. Place into the freezer while you melt the chocolate
Melt the chocolate in a double boiler (Bain Marie) or in the microwave. Remove the slab from the freezer and pour over the melted chocolate and spread out. Sprinkle over a tiny bit of flaky salt and place back in the freezer for the chocolate to set (around 20-30 minutes)
Remove and slice into bars. You can store these in an airtight container either in the fridge or freezer, depending on the texture you prefer. I prefer to store in the freezer because I love the texture after they’ve thawed for a few minutes. Enjoy!
