White chocolate & pistachio traybake

They’re part cake, part blondie — and 100% delicious.

These white chocolate and pistachio tray bake squares are packed with chunky pieces of white chocolate and crunchy pistachios. The edges bake up beautifully chewy, while the centre stays soft and buttery. Go big or go home, right?

You may have noticed I’m a little obsessed with tray bakes at the moment. They’re easy, versatile, and pretty much foolproof. One pan, minimal washing up, and perfect for even the tiniest kitchens — which is ideal for me right now!

We’re currently living in a rental property while we renovate our new home, so baking space is very limited. Most of my days are spent covered in brick dust rather than icing sugar! I promise more bakes are coming when the kitchen is finally finished.

This white chocolate and pistachio tray bake has the best of both worlds — an ultra-soft centre, a chewy edge, and a slightly dense, buttery texture thanks to all that glorious butter and eggs. Honestly, butter is just magic.

To finish, I drizzle extra white chocolate over the top and sprinkle on some crushed pistachios for a pop of colour and a little extra crunch. It’s simple but makes such a difference — plus, it’s just so pretty!

Tips & Tricks:

• Use good quality white chocolate: It melts better and gives a richer flavour throughout the tray bake.

• Don’t overmix the batter: Gently folding everything together keeps the texture soft and chewy, rather than tough.

• Chop the pistachios roughly: This gives you little bursts of flavour and a nice bit of crunch in every bite.

• Watch your baking time: Blondie-style tray bakes should be just set in the middle. If the edges are golden but the centre still looks slightly soft, that’s perfect – they’ll firm up as they cool.

• Decorate while warm: Drizzling the white chocolate when the tray bake is still a little warm helps it set with a glossy finish.
