Start with the base layer. In a food processor, mix the peanut butter, tahini, sweetener, coconut oil, sea salt and almond meal until well combined (If you have a Thermomix, mix 30 seconds, speed 4).
Press into a slice tin (mine is 20 x 30cm), lined with baking paper.
Place the almonds on top and press into the filling. Pop in the freezer until firm.
To make the chocolate, mix the melted coconut oil, rice malt and cacao in a small mixing bowl until combined (only takes a minute). If the ingredients are cold and not combining well you may need to warm slightly by sitting the bowl over a pot of steaming hot water.
For a snickers slice, pour over the base layer and return to the freezer immediately, for 20-30 minutes to set.
To make a bar, you will need to cut your filling once set into the size bar you want, then working quickly toss it in the raw chocolate to coat. Place the bars on a tray lined with baking paper and pop back in the freezer to set for a minute or so. Repeat until it coated to your liking. It will need at least two coats if using raw chocolate (and only one if using melted dark chocolate).
Once set cut and store in the fridge or freezer.
