Line a 9 x 13 inch (22cm x 33cm) rectangle baking tin with parchment paper, set aside.
Add peanut butter, maple syrup and coconut oil to a medium-sized pot.
Place it over a low heat on the stovetop and slowly heat mixture until ingredients are completely melted together, mixing occasionally with a wooden spoon to break up the peanut butter. TIP: The peanut butter will take the longest to melt. Keep mixing until it blends through the mixture.
Turn off heat and stir through desiccated coconut.
Add puffed rice cereal and mix until completely coated in the mixture.
Spoon mixture into lined tin. Using the back of a wooden spoon or a rubber spatula, firmly press it in, creating an even layer.
Place into the refrigerator for 15-20 minutes until it firms up.
While the base is setting, make chocolate topping.
Chocolate Topping
Prepare a double boiler by placing a small/medium heat-proof mixing bowl over a medium-sized pot of simmering water.
Into the bowl, add chocolate chips and coconut oil. Melt over low-medium heat, mixing occasionally with a rubber spatula.
Once completely melted and smooth, turn off heat and remove bowl from pot.
Remove base from fridge.
Pour melted chocolate over the base and using the spatula, gently and evenly spread it out. TIP: move the tin around using your hands in gentle motions so the chocolate spreads out itself.
Return to the refrigerator and chill for 1-2 hours or until chocolate topping as set and base has firmed up.
Remove from fridge and before cutting, remove the entire slice from the pan, still on the parchment paper, and allow it to sit at room temperature for 5-10 minutes so the chocolate topping softens slightly, making it easier to cut through.
Slice into long bars and enjoy!
Notes
The base mixture: Firmly press the base mixture into your lined tin. Don't leave any parts loose otherwise, the bars will crumble.
Refrigerate the base: Before adding the chocolate topping, chill the base for 15-20 until it firms up slightly. This makes it easier to spread over the chocolate.
Store in an airtight container refrigerated for 1 week - 10 days.
Freeze the bars in zip-lock baggies or wrapped in parchment paper or foil and place them into a freezer-friendly airtight container. Label with the date and recipe name. Freeze for 2-3 months.
Thaw the bars in the fridge overnight or at room temperature for 1 hour or until defrosted.
