It will come as no surprise to find out that I’m partial to a chocolate brownie, and having tried a fair few, I can safely say this variety (which I threw together as an experiment and didn’t have particularly high expectations for) is now a firm favourite. With a blackberry and cherry compote core and hazelnut praline top, these moist and deeply chocolatey bars deliver the dense, moist texture you expect from a great brownie, but also carry a welcome tang and contrasting crunch which make them a little different and perfect for late summer.
For the hazelnut praline
- 150g blanched hazelnuts
- 150g caster sugar
- Generous pinch sea salt
For the black forest fruit filling
- 400g fresh or frozen black forest fruits (blackberries, cherries, blackcurrants- choose one or use a combination depending on your preference/availability)
- 2tbsp caster sugar
- Zest and juice 1 lemon
- 4tbsp kirsch (optional)
For the brownie batter
- 250g butter, cubed
- 250g dark chocolate
- 100g dark brown soft sugar
- 100g golden caster sugar
- 3 eggs, plus 1 egg yolk
- large pinch sea salt
- 100g plain flour
- 100g white chocolate, roughly chopped
- 100g dark chocolate, roughly chopped
- Before you make the brownie batter, prepare the fillings. Start with the hazelnut praline; to make this simply place the sugar in a heavy bottomed pan and heat gently until it forms a caramel (don’t stir, just swirl the pan to move the sugar around). Once the caramel has taken on a golden colour, add the hazelnuts and stir to coat. Scrape the contents of the pan onto a baking paper lined tray and spread out in an even layer. Leave to harden.
- To make the black forest filling, place 300g of the fruit in a saucepan along with the caster sugar, lemon zest, lemon juice and kirsch (if using). Heat gently until the berries release their juices, then increase the heat to medium and, stirring occasionally, reduce to a compote consistency. Set aside to cool.
- The caramel will now have hardened around the hazelnuts. Break it up into pieces and place in a food processor, then blitz until you’ve got a coarse crumble (don’t over blitz, you want a little texture to remain).
- Now it’s time to make the brownie batter. Preheat the oven to 170c and grease and line a 20x20cm brownie tin. Put the chocolate and butter in a heatproof bowl and melt together over a pan of simmering water. Set aside to cool a little.
- While the chocolate mixture cools, place the sugars, salt, eggs and egg yolk in a stand mixer (or in a large bowl) and beat until very light and voluminous (it will pretty much double in size).
- Once the egg mixture is ready, pour the chocolate mix down the side of the bowl and fold in using a large metal spoon, then add the flour and do the same until you have a smooth, lump free batter. Now add the chocolate chunks and stir through to evenly distribute.
- Tip half the mix into the brownie tin and level off. Scrape in the black forest filling and sprinkle over most of the hazelnut praline. Top with the rest of the brownie batter then, finally, scatter on the remaining fruits and praline.
- Bake for 25-30 minutes.
- When it’s ready, the brownie will have a crisp top but will wobble slightly when shaken and have a gooey texture inside. Set aside to cool (completely) in the tin then once it’s set up a little, remove, slice up and serve.
