The addition of nuts elevates this humble ingredient into something truly special.

The buttery shortbread base provides a comforting foundation, while the gooey treacle filling offers a burst of rich, caramel-like sweetness.

this Recipe

Ingredients:

• For the Base:
• 250g plain flour, plus extra for dusting
• 125g cold unsalted butter, cubed
• 50g caster sugar
• 1 large egg yolk
• 2-3 tbsp cold water
• For the Nutty Treacle Filling:
• 150g unsalted butter
• 150g golden syrup
• 100g black treacle
• 100g light brown soft sugar
• 2 large eggs, lightly beaten
• 200g mixed nuts (walnuts, pecans, almonds, hazelnuts), roughly chopped
• 1 tsp vanilla extract
• Pinch of salt

Preparing the Pastry Base:

1. First, let’s tackle the pastry. In a large bowl, combine the flour and cubed cold butter. The key here is to keep the butter cold, so work quickly! You can also use a food processor for this step if you prefer.
2. Using your fingertips (or the food processor), rub the butter into the flour until the mixture resembles breadcrumbs. You’re looking for a fine, sandy texture with no large lumps of butter remaining. This is crucial for a tender, flaky crust.
3. Stir in the caster sugar. Make sure it’s evenly distributed throughout the flour and butter mixture.
4. Add the egg yolk and 2 tablespoons of cold water. Mix gently with a knife or spatula until the dough starts to come together. If it seems too dry, add the remaining tablespoon of water, a little at a time, until it forms a cohesive ball. Be careful not to overwork the dough, as this will develop the gluten and make the pastry tough.
5. Turn the dough out onto a lightly floured surface and gently knead it into a smooth disc. Wrap the disc tightly in cling film and chill in the refrigerator for at least 30 minutes. This resting period allows the gluten to relax, resulting in a more tender pastry. You can even chill it for longer, up to a couple of hours, if you need to prepare it in advance.
6. While the pastry is chilling, you can prepare the nutty treacle filling. This will save you time later.

Making the Nutty Treacle Filling:

1. Now for the delicious filling! In a large, heavy-bottomed saucepan, combine the butter, golden syrup, black treacle, and light brown soft sugar. The heavy-bottomed pan is important to prevent the mixture from scorching.
2. Place the saucepan over a low heat and stir constantly until the butter is melted and the sugar has dissolved. Be patient and don’t rush this step. You want a smooth, glossy mixture.
3. Remove the saucepan from the heat and allow the mixture to cool slightly for about 5-10 minutes. This is important because you don’t want to cook the eggs when you add them.
4. Gradually whisk in the lightly beaten eggs, a little at a time, ensuring that they are fully incorporated into the mixture. Whisk constantly to prevent the eggs from scrambling.
5. Stir in the chopped mixed nuts, vanilla extract, and a pinch of salt. Make sure the nuts are evenly distributed throughout the filling. The salt helps to balance the sweetness of the treacle.
6. Set the filling aside while you prepare the pastry case.

Assembling and Baking the Nutty Treacle Slice:

1. Preheat your oven to 180°C (160°C fan/Gas Mark 4). Make sure your oven is properly preheated for even baking.
2. Remove the chilled pastry from the refrigerator and unwrap it. Place it on a lightly floured surface and roll it out to a thickness of about 3-4mm. You want it to be large enough to line a 20cm (8 inch) square baking tin.
3. Carefully lift the pastry and line the baking tin, pressing it gently into the corners and up the sides. Make sure there are no air pockets between the pastry and the tin.
4. Trim off any excess pastry from the edges of the tin. You can use a sharp knife or a rolling pin to do this. Then, prick the base of the pastry case all over with a fork. This will prevent it from puffing up during baking.
5. Line the pastry case with baking parchment and fill it with baking beans or rice. This is called blind baking and it helps to prevent the pastry from shrinking and becoming soggy.
6. Bake the pastry case in the preheated oven for 15 minutes. Then, remove the baking beans and parchment and bake for a further 5-10 minutes, or until the pastry is lightly golden brown. Keep a close eye on it to prevent it from burning.
7. Remove the pastry case from the oven and allow it to cool slightly.
8. Pour the nutty treacle filling into the pre-baked pastry case, spreading it evenly.
9. Return the slice to the oven and bake for 25-30 minutes, or until the filling is set and golden brown. The filling should be slightly wobbly in the center, but it will firm up as it cools.
10. Remove the nutty treacle slice from the oven and allow it to cool completely in the tin before cutting it into squares. This is important because the filling will be very soft when it’s hot.
11. Once the slice is completely cool, cut it into squares and serve. It’s delicious served warm or cold, and it’s perfect with a scoop of vanilla ice cream or a dollop of clotted cream.

Tips for Success:

• Cold Butter is Key: Always use cold butter when making pastry. This helps to create a flaky crust.
• Don’t Overwork the Dough: Overworking the dough will develop the gluten and make the pastry tough.
• Blind Baking is Essential: Blind baking the pastry case prevents it from shrinking and becoming soggy.
• Cool Completely: Allow the slice to cool completely before cutting it into squares. This will prevent the filling from running.
• Nut Variations: Feel free to experiment with different types of nuts in the filling. Walnuts, pecans, almonds, and hazelnuts all work well. You can also add dried fruit, such as raisins or cranberries.
• Storage: Store the nutty treacle slice in an airtight container at room temperature for up to 3 days.

Troubleshooting:

• Pastry is Tough: This is usually caused by overworking the dough. Be careful not to over-knead it.
• Pastry Shrinks: This can be caused by not chilling the dough for long enough or by stretching the pastry too much when lining the tin.
• Filling is Runny: This can be caused by not baking the slice for long enough or by not allowing it to cool completely before cutting it.
• Filling is Too Hard: This can be caused by overbaking the slice. Keep a close eye on it and remove it from the oven when the filling is set but still slightly wobbly in the center.

Variations:

• Chocolate Nutty Treacle Slice: Add 2 tablespoons of cocoa powder to the flour when making the pastry. You can also add chocolate chips to the filling.
• Ginger Nutty Treacle Slice: Add 1 teaspoon of ground ginger to the flour when making the pastry. You can also add chopped crystallized ginger to the filling.
• Salted Caramel Nutty Treacle Slice: Add a pinch of sea salt to the filling and drizzle with salted caramel sauce before serving.

For a richer experience, try drizzling a little melted dark chocolate over the top.
