Thick and chocolatey pistachio brownies studded with white chocolate chips and chopped pistachios, swirled with a homemade pistachio spread
We all knew that a recipe for pistachio brownies was going to happen, because why would it not?! I posted my homemade pistachio spread recipe last week, and I baked these straight away using it – heaven in every bite.
Pistachio bakes
We have all been aware of the insane pistachio craze that has basically taken over recently, and I am sorry in advance if you don’t like pistachio. I have wanted to post more pistachio recipes for a while, so I am glad I am finally getting them out there now. Yes, I am truly and utterly happy to be involved in the pistachio craze as I do adore it myself.
When it has come to pistachio, I have posted a few recipes over the years, but definitely not enough. I adore baking the white chocolate pistachio cake for a celebration, and also the white chocolate pistachio cheesecake because it’s just luxurious and delicious.
The good thing, typically, about a pistachio recipe – if you don’t like pistachios, or you just prefer another nut, you can switch them out super easily. You can use hazelnuts, almonds, peanuts, pecans etc – in the same way. A recipe like these are always customisable and perfect for different flavour palettes.
Pistachio Spread
I posted my homemade pistachio spread last week, and you guys have loved it. It’s a simple recipe that really does level up your bake if you want to make it yourself. I use a mix of blanched pistachios, white chocolate and a little milk to create my spread – and then as soon as it’s made and ready to go, it can be used in this brownie recipe.
If you don’t want to make your own pistachio spread, that is totally and utterly fine. It’s easy to buy a pistachio spread online, or in some supermarkets at the minute. The stock varies from season and shop so it’s worth searching your local shops if you aren’t too sure or having a browse online. The popularity of pistachio bakes has luckily made pistachio spread far more widespread.
Brownie Bakes
When it comes to brownies, I have posted a fair few recipes now (is there such thing, as too many? I don’t think so) and I just love them. I think brownies are such an iconic bake across the world, it’s hard to get bored of them. It’s something that people classically love, and might do the typical “Oh yeah, go on then… I’ll have a piece” as that is certainly what I do.
My classic triple chocolate brownie recipe is just insanely popular – and often is the base to the rest of the brownie recipes I have published; including this one. A mix of 6 simple ingredients makes a thick, fudgy and glorious brownie that I will happily say is loved by thousands already. Dark chocolate, butter, eggs, sugar, flour and cocoa is the base of a brownie for me, no matter the flavourings that you add later on.
Brownie Batter
So, when it comes to this particular pistachio brownies recipe, it’s super easy. It’s a mix of the classic brownie base, white chocolate chips and chopped pistachios, and then a swirl of my homemade pistachio spread, of course.
- Chocolate – I will always say it, dark chocolate is important for the best bake. I use and recommend 70% cocoa content or higher
- Butter – you can use block unsalted butter, or a baking spread in brownies
- Eggs – I use medium eggs, but you can use large. 4 medium or 3 large works for brownies.
- Sugar – I like to use light brown soft sugar, or caster sugar, depending on flavour or even just what I have in the cupboard. On this occasion, I used light brown soft sugar
- Flour – plain flour as always, guys.
- Cocoa – I use a really strong cocoa powder because I love how chocolatey it is.
Making the brownies
The brownies themselves are quite easy to make. I start by melting the dark chocolate and butter together until smooth. You can do this in the microwave (as I do), or you can add the ingredients to a bowl, and place it above a pan of simmering water and melting. Leave this to cool for 10 minutes or so, so that the heat doesn’t melt the other ingredients or scramble the eggs.
Once the chocolate/butter mix has cooled, I add the eggs and sugar to a new bowl and whisk to a thick mousse like mixture – this often takes a few minutes whether by hand or electric mixer, but you want to create a large amount of air. The whisk typically leaves a trail in the mixture if you lift it out.
Fold the chocolate mixture into the egg mix, then fold in the flour and cocoa powder, carefully. Add in the chocolate chips and chopped pistachios, and fold again. Pour into a lined 9″ square tin and then dollop in the pistachio spread and swirl.
I bake in a preheated oven for 25 minutes, until there is a small wobble in the middle of the tin. I let the brownies cool, and then set the brownies in the fridge for a super fudgy and delicious texture of brownie.
How to make this recipe Free-From
Gluten free – Swap the flour to gluten free plain flour (make sure all other ingredients are gluten free). For texture, you can add 1/4tsp xanthan gum per 150g of flour if it doesn’t already contain it
Dairy free – Make sure the base chocolate is dairy free (lots of dark chocolate’s are) and swap the butter to a dairy free butter, and make sure the chocolate is dairy free. The pistachio spread I make isn’t dairy free, but you may be able to buy one or skip this bit
Vegan – use my vegan brownie recipe as a base, and add the pistachios to that
Tips & Tricks
It’s important to use the correct ingredients and size tin for a bake, especially brownies. Changing the tin size to a smaller tin will likely cause them to not bake properly for example, as volume differences can be more drastic than you may realise.
- These brownies will last to 5-7+ days at room temp, or in the fridge (I personally choose the fridge)
- These brownies will freeze for 3+ months
- You can use any flavour chocolate chip or chunk to add into the brownie, I just chose white chocolate
- The pistachios are optional, but delicious.

Just wondering, is the first paragraph of the blog supposed to say brownies instead of blondies? It left me puzzled for a bit: ” Thick and chocolatey pistachio blondies studded with white chocolate…..”
Regardless, these look amazing and can’t wait to give a try !
I made these with shop bought spread and was really disappointed when it didn’t stay green when baked!?
Will a homemade version stay green?
Mine was made with my homemade spread and it stayed green – the shop bought one may have additives that when heated, changed it? I’m unsure!
Are there any shop bought pistachio spreads you could recommend if I don’t make my own that would work well in this recipe? I have tried to incorporate shop bought spreads into baking before and they never seem to set.
