Ingredients

Here are all of the ingredients you'll need for this recipe:

Golden syrup: Golden syrup helps to improve the traybake texture and helps the other ingredients mix together properly. If you simply melted chocolate and butter together it would be very likely to split.
Cocoa powder: This is simply to give a stronger chocolate flavour. Always use unsweetened cocoa powder when baking unless the recipe states otherwise.
Butter: Much like the golden syrup, butter is in this recipe for the texture. It adds a rich flavour and makes the traybake easier to cut into once it’s cooled.
Milk chocolate: I used milk chocolate in the base and for the topping of my Twix tray bake. You can use any type of chocolate for the topping but for the base, stick to milk or semi-sweet chocolate to avoid splitting or seizing.
Digestive biscuits: Coupled with the Twix, Digestive biscuits add some nice crunchy texture in there. You can also use Rich Tea biscuits or any other biscuits you like.
Twix bars: The star of the show! You’ll need 200g of Twix bars for this tray bake plus more for topping. In total, I used 6 full-sized Twix bars (6 packs of two sticks).

Equipment

You'll need a few tools to make this recipe:

8x8-inch tin: This is the perfect size for Twix traybake. I don't recommend using a larger tin unless you also multiply the ingredients.
Baking paper: To stop the tray bake from sticking to the tin. You can leave a little extra hanging over the edges so you can simply lift it out after the traybake is set.
Mixing bowl: You'll need quite a large one, to give you enough room to properly coat the biscuits in chocolate.
Wooden spoon: Or a rubber spatula, to mix all of the ingredients together.
Rolling pin: You can use a rolling pin to help you crush the Digestive biscuits into chunks for the tray bake base.
Saucepan or heatproof bowl: You'll need a saucepan or heatproof bowl to melt the base and topping ingredients.
Sharp knife: To cut the tiffin into slices and also to chop the Twix bars.

How to make Twix tray bake

Step 1: Line an 8x8-inch tin with baking paper, leaving a little hanging over the edges for easy removal later on. Set aside for now.

Step 2: Place 150g of Digestive biscuits into a bowl and use a rolling pin to break them up into medium-sized pieces.

Step 3: Chop 200g of Twix bars into chunks and place them into a large bowl with the Digestive biscuits. 200g of Twix equals around 5 full-sized Twix bars (or 10 sticks of Twix in total).

Step 4: Break up 150g of milk chocolate and put it into a saucepan along with 100g of butter, 3 tablespoons of golden syrup and 2 tablespoons of cocoa powder. Place the saucepan over low heat on the stove and stir occasionally until melted.

Step 5: Pour the melted chocolate mixture into the bowl with the Digestive biscuits and Twix pieces. Mix well until evenly coated then press the mixture into your lined tin.

Step 6: Melt 200g of milk chocolate and spread it evenly over the biscuit base in the tin.

Step 7: Chop 40g more Twix bars into small chunks and stick them on top of the melted chocolate topping.

Step 8: Place your Twix traybake into the fridge for 2 hours until the topping is firm to the touch.

Step 9: Remove it from the tin, cut it into squares and enjoy!

Top tips

For a crack-free slice, you can warm up your knife by dipping it into boiling water and drying it thoroughly immediately before using.
The milk chocolate topping can be swapped for any other chocolate. However, for the base, it's best to use either milk chocolate or semi-sweet chocolate to prevent splitting or seizing.
Try using white chocolate Twix bars for an extra fancy traybake!

FAQ

How long does Twix tray bake last?

If you store it correctly, it'll last for up to two weeks. Store the slices in an airtight container in the fridge or in a cool, dark place such as a kitchen cupboard.

Can I freeze it?

Yes, this dessert is great for freezing! You can wrap slices of it in tinfoil or clingfilm, or pop them into an airtight container or ziplock bag. Use squares of baking paper in between to stop the pieces from sticking together.

When you're ready to eat it, let it thaw in the fridge overnight or let it sit out at room temperature for an hour or two. Once defrosted, do not refreeze.

Can I use different biscuits?

Yes, you certainly can! If you don't want to use Digestives, feel free to use another type of biscuit. Shortbread would go really well with the Twix bars but other options include Rich Tea biscuits, shortcake biscuits and gingernuts.
