Halloween Dessert Tips

  • Make sure you use a food processor to blitz the Oreos. Usually I say a bag and a rolling pin is fine but with the addition of the cream fillings – it just won’t work in this case.
  • Make sure you chop the chocolate as finely as possible to ensure even/fast melting once the hot cream is poured on top.
  • Work with haste when creating the spider web pattern on the top. Ganache starts to set quite quickly.
  • Has the chocolate not fully melted after the 5 mins is up? Don’t worry! Give it a stir then heat in the microwave in 10 second intervals (stirring well each time) until completely melted.
  • Read the recipe through before beginning! Simple but important.
  • Don’t boil the cream. Only heat until it just starts to bubble.

Halloween Dessert | Bloody Spider Web Chocolate Tart Recipe

Here is what you will need to serve 8 – 10.

The Base

  • 245g (8.5 oz) Oreos
  • 80g (1/3 cup) Unsalted Butter


The Filling

  • 200g (7 oz) of Caramel *
  • Red Food Colouring Gel
  • 175g (6 oz) Dark Chocolate, Finely Chopped
  • 50g (1/4 cup) Unsalted Butter, Room Temp
  • 165ml (2/3 cup) Double Cream


To Decorate

  • 50g (1.75 oz) White Chocolate
  • Plastic Spiders, Optional


Essential Equipment

  • 20cm (8″) Loose Bottomed Tart Tin
  • Food Processor
  • 1 x Disposable Piping bag


*I used Carnation caramel

To make the base, tip the Oreos into the food processor (including the cream filling) and pulse until fine crumbs are formed.

Then gently melt the butter in a small saucepan or in the microwave and pour into the processor with the Oreo crumbs. Pulse a few times until it starts to clump together.

Tip the mixture into the tin and press firmly into the base & sides with a metal spoon. Pop into the freezer to firm up whilst we crack on with the filling.

Pour the caramel into a bowl & add a generous amount of red food colouring gel using a cocktail stick. Mix really well. You can keep adding more colour until you reach your desired shade but make sure to do it a little at a time as you can always add more but you can’t take it out!

Pour the ‘blood caramel’ over the chilled Oreo base & spread out evenly. Pop back into the freezer whilst we make the chocolate tart filling.

If you haven’t already, finely chop the dark chocolate & cut the butter into small pieces. Place it all into a large glass bowl and set to one side.

Then pour the double cream into a small saucepan and gently bring to the boil. (Don’t continue to let it boil – turn the heat off as soon as it starts to boil.)

Pour over the chocolate and leave to stand for 5 minutes.

When the 5 minutes are up, give it a really good stir with a spatula. It should turn into a beautifully smooth & silky bowl of chocolate ganache heaven.

Working quickly, (as the ganache will start to set pretty fast) break the white chocolate into a bowl and microwave in 10 second intervals. Stir well between each time and keep heating until it’s melted and smooth.

Pour the melted chocolate into the disposable piping bag and snip a small bit off the end. Starting from the middle of the tart working outwards, pipe a spiral of white chocolate.

Then using a skewer or knife, gently pull lines from the middle to the edge going all the way round the tart. It should end up looking like a spider’s web.

And that’s it! Pop it into the fridge to set for at least an hour before serving. Consume within 3-4 days.

  1. Michelle s says:

    Im in the US trying to make this recipe. I am unable to find double cream and the liquid caramel. any suggestions?? I havent made it yet.

    1. Miss KitchenMason says:

      Hi Michelle. I believe the closest substitute you have in the US for double cream is whipping cream. As for the caramel, you could try making your own maybe? There’s a good recipe here: Just skip adding the salt, unless you’d like to add it in of course! Emma x

  2. Rita says:

    Could you please convert this to cups and ounces.

    1. Miss KitchenMason says:

      Hi Rita. I don’t personally use cups or ounces as I find metric to be much more accurate. As a result, I don’t understand how to properly convert from grams to cups etc. There are lots of great conversion websites out there that might be able to help though?

  3. Thank you for your recipe. I adopted it on my blog, I have linked it on my blog. It is super delicious!

    1. Miss KitchenMason says:

      Glad you like my recipe and thank you for the share 🙂

  4. Megan Rauch says:

    I shopped at Trader Joe’s so I used their sea salt caramels

    1. Aaah right. I’m in the uk and we don’t have that shop but is it safe to assume you used hard candy caramels as opposed to a can of caramel?

      1. Megan Rauch says:

        They were soft caramels. I’ll try hard candies next time. Thank you for your replies!

        1. Miss KitchenMason says:

          Don’t use caramels at all, just use a can of caramel. The liquid stuff. I used this Carnation Caramel And you’re welcome! Anything I can do to help 🙂

  5. Megan Rauch says:

    Does the caramel melt right away just by leaving it out on the counter? My caramel seemed to harden quickly at room temp as I was spreading it on the crust. Thanks!

    1. Miss KitchenMason says:

      It depends on what caramel you used and how long you left it in the freezer for I guess. It shouldn’t matter too much anyway as it’s trapped in by the biscuit base & chocolate ganache so it’s not going anywhere 🙂

    2. Sorry, I’ve just re-read this. It shouldn’t be hard at all, especially at room temperature. What caramel did you use? I used Carnation caramel.
