Why you should make this Halloween Spider Web Chocolate Tart
Chocolate is the theme here but let’s dive into the different elements that make up this festive tart!
- Chocolate spiders – made of simple melted chocolate and chocolate candy. You could even use these for cupcakes or cakes!
- Oreo crust – made out of crushed Oreos. Nice crispy, buttery contrast to the ganache
- Chocolate ganache – the ganache is made of milk and dark chocolate and is silky smooth because of the butter used in it.
- Spiderweb decoration – an easy to make pattern using chocolate ganache and a piping bag or squeeze bottle.

Tip – Press the crust as firmly into the tart tin as you can for an even tart shell.

Instructions
Chocolate Spiders
- Pipe little blobs of melted chocolate on a baking tray lined with baking paper. Stick the candy on top. Pipe a little chocolate blob above the candy, then spiders’ legs coming out on the sides. Allow to chill in the fridge completely before using.
Oreo Crust
- Prepare crust mixture – Add the Oreos to the bowl of a food processor and pulse until you reach fine crumbs. Alternatively, you can add the cookies to a large zip lock bag and crush using a rolling pin. Pour the butter into the crumbs and pulse or mix until the crumbs are coated and resemble wet soil. When squeezed together in your hand it should come together, kind of like a cookie.
- Form and chill – Pour the mixture into an 8-inch wide (1-inch high) tart tin and use the back of a spoon to firmly press into the sides and bottom. Chill in the fridge for 10 minutes.
Ganache Filling
- Melt ingredients – Add all of the ingredients into a heatproof bowl and melt in the microwave for 30 seconds bursts, stirring each time until melted and smooth. Pour most of it into the tart. Set about 1/4 cup aside for web details. Allow filled tart to set completely for 1 hour.
White Ganache
- Melt ingredients – Repeat the same process as the ganache filling, allow to cool slightly before pouring on top of the chilled tart. Use a spoon to spread around evenly.
To decorate
- Fill a squeeze bottle or piping bag with remaining ganache filling and pipe lines across the white ganache. Then, starting from the center, fill in with a swirl of spider web pattern. Place the spiders on top and allow to set in the fridge for an hour.

Do you blend the oreos with the cream centers or do you remove the cream?
Such a great question. With the cream! N x
Great fun! Can you also provide the recipe for the piping you use to make the sprider legs? thank you.
Hi Ava! Thanks! I just melted 10g of dark chocolate and added it to a piping bag to pipe out the legs 🙂 N x
