It’s no secret how much I love a tray bake. They’re some of the easiest recipes to make and everyone has a favourite. One of the most requested tray bakes we get though is Peppermint Slice.
This super simple tray bake is a big favourite with The Boys. Both have recently discovered mint-chocolate ice cream and will always choose a Mint Aero when allowed to pick a sweetie. Taking after their Granny in that department, who has always been a fan of mint Poppets and a box of Bendicks at Christmas.
As far as tray bakes go, this one takes a little bit of time investment, purely because you need to let the layers set in between. But that aside, it’s one that anyone can manage and with a bit of crushed Mint Aero on top, it’s sure to wow anyone who you share it with…that’s if there’s any left to share!
Peppermint Slice
Ingredients
For the Base
- 225 g Digestive Biscuits
- 1 tbsp Caster Sugar
- 115 g Butter
- 3 tbsp Cocoa Powder
- 50 g Dark Chocolate
For the Filling
- 340 g Icing Sugar
- 3-4 tsp Hot Water
- 2-3 tsp American Peppermint Extract
- Green Food Colouring (optional)
For the Topping
- 300 g Dark Chocolate
- Crushed Mint Aero (optional)
Instructions
- Generously grease a 28x18cm tray with butter and set aside. In a pan, melt the butter, sugar, cocoa and sugar.
- Meanwhile, crush the disgestive biscuits, either in a sandwich bag with a rolling pin, or blitz in a blender. Add to the melted mixture and stir until combined.
- Transfer the base mixture to your prepared tray and using a wooden spoon, press the mixture into the tray, ensuring you get right into the corners and have an even finish. Place the base into the fridge to chill for 1 hour.
- Once the base has cooled, prepare the filling but sifting the icing sugar into a large bowl. Add 1 tsp of hot water at a time until you have a spreadable consistency; 3-4 tsp of water should be enough but add more or less as required.
- Add the peppermint extract and green food colouring (optional) to the icing and mix until well combined. Spread the icing evenly over the biscuit base and return to the fridge for another 1 hour to set.
- Once the filling has set, remove from the fridge and set aside. Over a bain marie (or in short bursts in the microwave) melt the dark chocolate before pouring and evenly spreading on top of the filling. If desired, top with some crushed Mint Aero.
- Allow the peppermint slice to set in the fridge for at least 1 hour but ideally overnight. Once set, cut into your desired size.
Just made this ,can’t wait to try tomorrow. Love your recipes
Sorry but this didn’t end well, the chocolate set rock hard and pushed all the icing out when I tried to hacksaw it into squares! Too much faffing about for me, I’ll stick to your Tiffin recipe!
Oh my word!! Fantastic recipe. By far the most delicious mint slice I’ve ever tasted and I MADE IT MYSELF!!! I used half milk chocolate and half dark. I cut it after 2 hours in the fridge (as I couldn’t wait any longer to try it) and it cut well. If I’d have left it over night I think the same would have happened as did with Karen. Will be making this again and again!!
