RECIPE NOTES & TIPS

Peanut Butter - store-bought peanut butter works better in this recipe than homemade or natural peanut butter.
Melting - you can melt the ingredients in the microwave, on the stove-top or in a Thermomix.
Don't add the marshmallows to the hot chocolate butter mixture - otherwise they will melt and you'll end up with a sticky mess! Allow it to cool before adding mini marshmallows.
Setting time - leave in the fridge to set for a minimum of 1 hour.
Cutting the slice - remove from the fridge 30 minutes before you want to cut the slice. Use a sharp knife to cut the room temperature slice. See my post for more tips to cut perfect slices.
Storing - store in an airtight container in the fridge for up to 1 week.
Freeze - wrap well and freeze for up to 1 month. Defrost in the fridge overnight.
