I was on the hunt for something green to make in honour of St Patrick’s day tomorrow. I love mint things but have never attempted a peppermint slice before and thought now was as good a time as ever to give it a go. Peppermint slice filling can be made with kremelta (vegetable shortening – what most bought slices tend to be made with), butter or melted butter. Not having any kremelta I adapted a couple of recipes and came up with the following recipe:
150g butter, softened
½ cup sugar
1½ cups flour
¼ cup cocoa
½ teaspoon baking powder
2-4 tablespoons of milk depending on how dry your mix is
200g butter, softened
2½ cups icing sugar, sifted
3 tablespoons cream
2 teaspoons peppermint essence
½-1 teaspoon green food colouring (depending on your desired colour)
200g dark chocolate
4 tablespoons cream
Preheat the oven to 180°C. Line an 18cm x 28 cm pan with baking paper.
Cream the butter and sugar with an electric beater until the mixture is light and fluffy. Sift in the flour, cocoa and baking powder. Mix together until combined. Adding milk as needed.
Press the mixture into the base of the prepared pan. Bake for 20-25 minutes until firm. Set aside to cool.
To make the filling, cream the butter and icing sugar until light and fluffy. Mix in the cream, peppermint essence and food colouring. Spread the mixture evenly over the cooled base.
Refrigerate for at least 30 minutes before topping.
To make the chocolate topping place the chocolate and cream in a heatproof bowl over a pot of simmering water and mix until smooth and combined. Allow the chocolate mix to cool for 10-15 minutes before pouring it over the peppermint layer and return to the fridge.
Wait for the chocolate to set before cutting the slice into small pieces (for a perfect finish, use the tip of a sharp knife to mark cutting lines in the chocolate topping just before it sets).
I hope you enjoy the slice as much as I am right now, if peppermint isn’t your thing but you’d like to bake something for your St Paddy’s day celebration you could try making this beer cake using Guinness or maybe some Bailey’s/Irish Cream cupcakes – I think that might be me next year!
