Ingredients you will need

** This post contains tips and instructions to achieve the best possible results. The photo above is a great guide for when you are in the supermarket, but for full ingredient quantities and methods, please scroll down to the detailed recipe card below!

• Oreos – crushed Oreos form the cookie/biscuit base of the tart. Don’t remove the Oreo filling, throw the entire biscuits into a food processor or crush them with a rolling pin. Oreos can be swapped for equal quantities of any other biscuit like Graham Crackers, Digestives, Chocolate Ripple, Granita or any type of plain, sweet biscuit. If using plain biscuits, leave the extra chocolate out of the base.
• Heavy cream – thickened cream or heavy whipping cream is used to make the ganache filling for the tart. Don’t use light/low-fat cream, milk or any other cream alternative, or the ganache won’t set properly and will be difficult to slice.
• Dark chocolate – when making homemade ganache, you need a 1:1 ratio of cream to chocolate. For the filling, I recommend using dark chocolate, semi-sweet or high-quality bittersweet (couverture) chocolate. Use a dark chocolate with 45%-70% cocoa and choose the best quality you can find, since it’s the key flavour in this dessert. Don’t use baking chocolate or chocolate chips, because they will not melt into the best ganache consistency.
• Butter – butter is used to both bind the biscuit base and to help set the ganache. And it also gives the ganache a beautiful glossy shine. Use unsalted butter, so that you can more easily control the salt content with salt flakes.
• Caster sugar – just 2 tablespoons, to add a little sweetness and balance the richness of the chocolate.
• Vanilla – vanilla extract or vanilla bean paste enhances the chocolate flavour.
• Salt flakes – sea salt flakes enhance the chocolate flavour and balances the bitter and sweet elements of the tart. Use salt flakes, rather than fine table salt.

Step by step instructions

Full recipe quantities and instructions can be found in the detailed recipe card below.

For the Oreo biscuit base;

1. Crush the biscuits – place the Oreos, chocolate and salt into a food processor and crush until the mixture is fine, like breadcrumbs.
2. Add the melted butter and mix. The mixture should have the consistency of wet sand.
3. Press the Oreo mixture into a 23 cm tart tin and refrigerate while you prepare the ganache filling.

For the chocolate ganache;

To make the chocolate ganache, we use a ratio of 1:1 cream to chocolate.

1. Finely chop the chocolate and place it into a heat-safe glass or metal bowl.
2. Heat the cream along with the sugar, vanilla and butter on the stovetop, until just simmering. Don’t boil! If the cream is too hot it can split or become grainy when added to the chocolate. Once it is just bubbling around the edges, remove the cream from the heat and pour over the chocolate.
3. Let the hot cream and chocolate sit for 2 minutes and then stir the mixture together until silky smooth. Allow to cool slightly.
4. Pour the ganache inside the biscuit base. Top with salt flakes, to taste.
5. Refrigerate until set (around 2 hours).

Expert tips

• Use a good quality chocolate that you love to eat. Chocolate is the key flavour and the quality of the chocolate will affect the flavour of the tart. Choose the best one you can find.
• Chop the chocolate as finely as possible for the ganache. The finer you chop the chocolate, the quicker it melts into the cream. Large chunks of chocolate won’t fully melt.
• Let the cream and chocolate mixture sit for a couple of minutes before stirring. During this time, the chocolate will melt and soften, requiring less stirring.
• Don’t overheat the cream. Heat the cream mixture until it is steaming hot and only just starting to lightly bubble at the sides. Don’t boil. Boiling the cream can make the chocolate filling split or become grainy.
• Slice the tart with a hot, clean knife for best results. Run the knife under a hot tap, dry, then cut. It also helps to let the slice sit at room temperature for 10 minutes before slicing, to soften slightly.
• If you notice any bubbles on the surface of the ganache, pop them with a toothpick before chilling.
• This tart is gorgeously rich! You only need a small slice. I recommend serving it with some double cream and fresh berries to cut though the richness. Or try any of the following; salt flakes, shaved chocolate, a dusting of cocoa, salted caramel sauce, roasted strawberries, praline, crushed peanut brittle, coulis or cream.
• Keep it chilled until ready to serve.
• This tart will keep in the fridge for 3-4 days, covered or in an airtight container.

• ▢ 370 grams Oreo cookies 39 cookies
• ▢ 60 grams dark chocolate finely chopped
• ▢ ¾ teaspoon salt flakes
• ▢ 115 grams butter melted

For the salted chocolate filling

• ▢ 400 grams dark chocolate very finely chopped. Choose a good quality one for best results
• ▢ 400 ml thickened cream heavy thickened or whipping cream

• ▢ 80 grams unsalted butter
• ▢ 1 teaspoon vanilla bean paste
• ▢ salt flakes

To serve

Instructions

For the biscuit base

• Set aside a 23 cm tart tin.
• Using a food processor, blend the Oreo cookies, dark chocolate and salt together until completely broken down and resembling breadcrumbs.
• Add the Oreo mixture to a bowl and add the melted butter. Stir to combine. The mixture should have the consistency of wet sand.
• Firmly press the Oreo mixture into the tart tin (base and sides) using a glass or metal spoon (or your fingers). Chill the base in the fridge or freezer for at least 10 minutes, while you prepare the chocolate ganache.

For the chocolate ganache filling

• Very finely chop the dark chocolate into very small pieces (large chunks won't melt into the mixture as easily). Place the chopped chocolate into a large, heat-safe bowl.
• In a saucepan, heat the cream, caster sugar, butter and vanilla over low heat, until steaming hot (but not boiling). Stir occasionally.
• Carefully pour the hot cream over the chocolate and allow to sit for 1-2 minutes without stirring.
• After 2 minutes, whisk or stir the mixture until the chocolate has melted and the mixture is smooth and glossy.
• Pour the chocolate filling into the biscuit base and sprinkle with some salt flakes, to taste. Chill in the refrigerator for around 2 hours, until set.
• Keep chilled until ready to serve. Slice and decorate with a dusting of cocoa powder (optional), fresh berries and double cream.
