Ingredients

Here's what you'll need to make this no-bake mint Aero traybake.

Milk chocolate: Milk chocolate forms the base of this traybake. You can also use semi-sweet chocolate if you prefer, but I would advise against using high-cocoa dark chocolate or white chocolate as the mixture may split.
Cocoa powder: Unsweetened cocoa powder will help add more chocolate flavour.
Golden syrup: Golden syrup helps to improve the traybake texture, making it easier to cut through when chilled. It also adds an extra touch of sweetness.
Butter: Much like the golden syrup, butter gives this traybake a slightly softer texture, making it easier to cut into. It also adds a rich flavour.
Digestive biscuits: Adding Digestive biscuits makes this traybake quite similar to a tiffin. You can use another type of biscuit such as Rich Teas or shortbread.
Mint Aero chocolate bar: I chopped up a few bars of mint Aero chocolate to mix into the traybake. It adds a nice pop of green colour!
White chocolate: I topped my Aero traybake with white chocolate rather than the usual milk but you can use whichever you prefer.
Mint Aero Bubbles: Lastly, you'll need some Mint Aero Bubbles for the traybake topping. They add so much glam and they taste incredible. Feel free to use chopped Aero bars instead.

Equipment

Mixing bowl and wooden spoon: To mix all of the Mint Aero tiffin base ingredients together. A rubber spatula will also work fine if you don't have a wooden spoon.
Rolling pin: To bash the Digestive biscuits into rough pieces. You could also break them up with your hands if you prefer.
Saucepan: You'll need this to melt the ingredients for the base together. You can also use a double boiler if you want to ensure the mixture doesn't burn or seize.
Heatproof bowl: This will make melting the white chocolate topping quicker because you can use the microwave, but you can melt it over the stove if you prefer.
Baking tin and baking paper: The ideal size for this Aero Bubble traybake is 8x8 inches. You can use a different size if you absolutely have to, but the slices may end up very thin. The baking paper will help to prevent it from sticking to the tin once set- you simply lift it right out!

How to make mint Aero traybake

Step 1: Line an 8x8-inch tin with baking paper. Set it aside for now.

Step 2: Place 200g of Digestive biscuits into a large bowl and break them up into medium-sized pieces. There should be any super large chunks but they shouldn't be completely crushed into crumbs either. Stir in 150g of chopped Mint Aero bar pieces.

Step 3: Break 150g of milk chocolate into pieces and add it to a saucepan along with 100g of butter, 3 tablespoons of golden syrup and 2 tablespoons of cocoa powder. Turn the heat to low and stir gently until the chocolate and butter have melted fully.

Step 4: Add the melted chocolate mixture to the bowl with the crushed Digestive biscuits and chopped Aero. Mix well until the biscuits are all covered in chocolate then press it into your lined tin.

Step 5: Now it's time for the topping! Melt 200g of white chocolate in the microwave, mixing it with ½ teaspoon of peppermint extract if you want a stronger mint flavour. Spread it evenly on top of the biscuit base.

Step 6: Top with 180g Mint Aero Bubbles or more Aero bar pieces. Refrigerate for 2 hours until firm.

Top tips

Add ½ teaspoon of peppermint extract to the white chocolate topping if you want a stronger mint flavour.
Make sure to let the traybake set for the full amount of time before cutting into it, otherwise it may melt or crack.
If using a larger tin than 8x8, I recommend increasing the ingredient quantities by 1.5.
For a crack-free slice, warm your knife by dipping it into boiling water and drying thoroughly before cutting.

It sure can! Simply pop the Aero Bubble traybake slices into an airtight container, dividing them with squares of baking paper to prevent them from sticking together. Freeze for up to 2 months.
