Popcorn Layer Ingredients

How to Make Chocolate Popcorn Bars
Start by lining an 8 x 8-inch (20 x 20cm) square tin with parchment paper and setting it aside. Ensure you leave enough overhang to make it easier to remove the bars from the tin.
Melt the chocolate and butter
Add the chocolate and butter to a medium sized heat proof bowl and melt them in the microwave at 20 second increments. Be careful not to overheat the chocolate. Once melted, set the bowl aside to cool.
Add the popcorn and marshmallows
Fold the popcorn into the cooled chocolate and butter while using your spatula to slightly break up the popcorn as you fold. Add in the mini marshmallows and coat them well with the chocolate.
Add the chocolate popcorn to a tin
Transfer the mixture to the baking tin and use a palette knife or the back of a spoon to spread and press the mixture tightly into the pan. Set the tin aside.
Melt the chocolate for the top layer
To a microwaveable bowl, add the chocolate and melt at 20 second increments. Once the chocolate cools, spread a thin layer on top of the chocolate popcorn. Refrigerate to allow the bar to set. Once set, cut into 16 squares and enjoy.
Recipe Tips
- I tend to use two different types of chocolate for the main mixture and top layer of chocolate. If I use milk chocolate for the main mixture then I use dark chocolate for the top layer and vice versa.
Storage
Store these popcorn bars in the fridge for up to 5 days. You can also freeze them for up to a month.
