White Chocolate & Pistachio

My favourite combination with pistachio has to be white chocolate, it’s simply perfect! These fudgy pistachio blondies are the ultimate blend of sweet, creamy white chocolate and the subtle nutty flavour of pistachios. You can easily switch things up by using milk chocolate or dark chocolate if you prefer a richer taste. That’s what I love most about blondies, they’re so easy to customise and always turn out delicious!

When I make blondies, I always melt white chocolate into the base. This is my secret to creating that signature fudgy, gooey blondie texture that everyone loves. You can make blondies without white chocolate, but trust me, it changes the texture completely. Melting the chocolate into the batter gives the perfect soft, rich, and chewy centre. I usually use the supermarket’s own brand white chocolate for the base, and if I’m adding chunks or drizzle on top, I’ll go for Milkybar or another creamy option. Just don’t use Milkybar for melting into the base, it’s better saved for add ins and decoration!

Ingredients

  • White chocolate– I use melted white chocolate in the base of this recipe. i just use a supermarket own chocolate, the cheapest i can find really!
  • Butter– I suggest using Unsalted Butter for blondies but you can use baking spread if you’d like.
  • Caster sugar– I use just caster sugar for my blondies For sweetness and added chewiness. You can use light brown sugar if you’d like to add some caramel flavours depending on what add ins you use!
  • Eggs– I use two eggs for structure and another egg yolk for richness. You can save the egg white for another bake!
  • Golden Syrup– I love adding golden syrup into my blondies, it adds sweetness and makes the texture even better trust me on this one!
  • Plain flour & Cornflour– I use plain flour and cornflour in this recipe. Cornflour helps achieve a fudgy, chewy texture. If you don’t have cornflour/cornstarch then you can just use plain flour! Don’t worry the blondies will still be amazing!
  • Pistachios– I used chopped pistachios in this recipe for that extra crunch! I also used carnations pistachio drizzle on top for more flavour and colour!
  • White Chocolate– I used white chocolate in this blondie as I love the white chocolate and pistachio combo but you could use milk or dark chocolate if you’d like!

Tips & Tricks

  • Store in an airtight container for up to 3 days or freeze for longer freshness.
  • Don’t overbake! Slightly underbaked blondies will set as they cool and stay fudgy.
  • I mix my blondies just until the ingredients are combined. Some recipes say to whip up your eggs or butter until light and fluffy but this isn’t Necessary for these blondies!
  • Let them cool fully before slicing for clean edges.
  • Make sure to use the right sized baking tin. I use a 9×9″ square tin for these blondies. This is the tin I use.

Frequently Asked Questions

Can I use regular chocolate instead of white?

Yes! Milk or dark chocolate chunks work great if you prefer a richer taste.

What if I can’t find Carnation Pistachio Drizzle?

In the UK, Carnations pistachio drizzle can be found in Home bargains and B&Ms. If you don’t have access to this, you can use any pistachio spread you like or even make your own!

Why are my blondies dry?

They’re likely overbaked, aim for slightly underdone in the centre; they’ll set as they cool. You will want a slight wobble in the middle when you take them out of the oven. Refrigerating them will help set them and create that dreamy fudgy blondie texture!

How Do I Know If My Blondies Are Baked?

This is one of the hardest things when it comes to baking blondies, knowing when to take them out at the right time. Using a skewer won’t help as blondies will still be gooey, similar to a brownie when they’re removed from the oven! They should have a slight wobble in the middle when you remove them from the oven, They will also set more as they cool down, wait until they are cool and put them in the fridge for 3-4 hours to ensure you get the BEST blondie texture. (Put it in the fridge still in the tin).

Storage And Freezing

These blondies last at room temp, or in the fridge for up to 3-4 days or you can freeze them for 2+ months. Wrap individual bars in baking paper and place in a ziplock freezer bag.
