Easy and delicious white chocolate blondies that are fudgey, sweet and perfect! White chocolate batter and white chocolate chips… heaven! 

Blondies vs Brownies

I know I have posted many blondie and brownie recipes over time now, but I still get questions about what blondies are in comparison to brownies! 

For me, a blondie is a ‘white’ version of a brownie. This is however my first recipe to include melted white chocolate in the base because it took so long to perfect the recipe to make sure it wasn’t greasy or horrible. 

I always use dark chocolate for my brownies, so white chocolate or plain base makes it… blonde! Blondies are sweet, delicious, and incredibly moreish. 

White chocolate

So as the main base for these blondies is white chocolate, you need to use good white chocolate. I use this one in all of my baking as I find it’s best, it doesn’t create a greasy texture, and it works perfectly for melting down and as chocolate chips. 

You can use basically any white chocolate you like, but generally, because you end up having to use quite alot I would save any brands as the chocolate chip part, and melt down the cooking or supermarket own for the base chocolate. 

I used white chocolate as the drizzle as well just to get one extra element of the white chocolate in, but this is optional. 

Tin

I always tend to use the same tin when I bake a traybake such as a brownie, blondie or cookie bar, because I find it creates the perfect depth of bake, and it bakes perfectly every time. 

For this recipe I used a 9″ square tin (23cmx23cm), and lined it with parchment paper. You can easily use a ‘brownie’ tin that is 7×11″ as this will take the same time, and have the same results. 

If you wanted to decrease the recipe to make half, a 7″ square would be the equivalent – but changing tin sizes does change the bake time. I tend to find its best to stick to the recipe and tin size, but freeze the other half for later. 

Baking

I know one of the scariest things about baking some traybakes is that ‘they never bake right’… when it’s actually much easier than you think. There are a few tips that really save me every time! 

The best place you can start is to use an oven thermometer to make sure your oven is actually baking at the correct temp. Some bakes you can get away with it being out, but for the best traybakes you really need it to be bang on! 

I always bake my blondies for exactly 25 minutes, until there is an ever so slight wobble in the middle of the tin. There is no point in doing the skewer test, as you want them to be a little be gooey when they are still warm! 

Cool the blondies completely in their tin, and then put them in the fridge overnight. This is BY FAR the best way to get a fudgey blondie delicious texture of heaven. 

Tips and Tricks

For this recipe I use:

  • This white chocolate – its good quality, tastes delicious, and so much easier to buy in chip form! 
  • This baking tin – 9″ square is the best size, and this is the perfect depth. 
  • Oven thermometer – making sure you have the temp bang on will save your bacon. 

These blondies can be used as a base for other recipes on my blog, but I do still utterly adore my other blondie recipes. Neither is better than the other in my opinion! You can use these for example topped with my millionaires blondies ingredients, or even follow the idea of my biscoff blondies

These blondies last at room temp, or in the fridge – or you can freeze them for 3+ months. ENJOY!

    Hi Jane – is there a major impact swapping the flour for gluten free flour? Or will they still work out ok?

  2. Teigan on June 22, 2025 at 7:47 pm

    How many large eggs would it be instead of medium, I only ever have large eggs not medium

  3. Emily on April 28, 2025 at 8:53 pm

    Can I add caramel to these? and if so do I need to change the times for baking?

    This is my go-to blondie recipe! I love trying all your different flavours and putting my own twist on them, too! I was thinking of making a Lucky Charms blondie but am not 100% sure how to do this? I love the idea of the ‘cereal milk’ being used in the batter or as a frosting, and want to use both the cereal and the marshmallows but don’t want to make the blondies too dry? Any tips would be greatly appreciated! Thanks 😊

    Would they still bake OK if I were to leave the white choc chips out please? Thinking to then roll them in cinnamon sugar so like the white choc and cinnamon blondies from the tik tok bakeries!

    Hi when it says mix in the sugars and flour is it just with a spoon or as whisk ?

    • Uti on March 24, 2025 at 4:56 pm

      Hello

      I‘m not sure at what temperature to bake them?!



  7. Zoey on January 24, 2025 at 5:27 pm

    I was really excited to try this recipe, but something has gone horribly wrong! My nice, smooth blondie mix went into the oven and now has melted butter pouring out of it everywhere. I triple checked my quantities before mixing and I just can’t figure out what has gone wrong or how to save the batch. Please, please can someone help?

    • Jane's Patisserie on March 3, 2025 at 12:46 pm

      What butter did you use? Was it a baking spread?



    • Tegan on June 4, 2025 at 1:17 pm

      I know I’m late to reply but I found that when I melt the chocolate and butter together, after mixing the sugars in the butter/grease separates. I tip out 2/3s of the greasy butter and then continue the recipe as normal and this seems to work!

  10. Elsa on December 5, 2024 at 4:24 pm

    is it possible to use gluten free flour instead? to cater for an intolerance

    • Isobelle on February 16, 2025 at 2:49 pm

      I used gluten free flour and they turned out perfect:)



  11. Jennie Morton on November 9, 2024 at 2:08 pm

    Can any blondies and brownies be frozen please?

    This is a great recipe I have made it 3 times!
    Once I added crushed biscoff biscuits which was a great addition, and today I’ve replaced the white chocolate with dark chocolate to make brownies and they have turned out great too!

    These are absolutely delicious and a total doddle to make.

    They’ll become a regular in our household, thank you.
