As we head on into autumn and the days become cooler, it’s the perfect time to get baking. If you’re looking for an easy, comforting traybake to try this white chocolate blondies recipe is just what you need!

I’d never personally tried a blondie before developing this recipe, so I was intrigued and excited to taste them. I knew I wanted to get a similar texture to my Chewy Homemade Brownies recipe and I think I achieved it! But what exactly is the difference between a brownie and a blondie?

What’s the difference between a blondie and a brownie?

Blondies are essentially a vanilla flavoured brownie. Brownies are typically made using cocoa powder to give them their chocolate flavour, whereas blondies are flavoured with vanilla and light brown sugar. Because classic blondies don’t contain this chocolate flavouring, they have more of a sweet, buttery, vanilla flavour. Otherwise, blondies have the same texture in that they are dense and chewy like brownies!

However, I’ve taken these blondies next-level by adding white chocolate flavour too. Both melted white chocolate and white chocolate chunks are added to the blondie batter so if you have a sweet tooth you will love these blondies!

White Chocolate Blondies Ingredients

The full ingredients list can be found in the recipe card at the bottom of this blog post but in summary, to make these white chocolate chip blondies you’ll need:

Plain flour for the blondie’s main structure
Salt to balance the flavours
Eggs for structure and chewiness
Light brown sugar for sweetness and soft, chewy centres
Vanilla for that classic blondie flavour
Melted butter for flavour and soft blondie centres

White chocolate chips both melted white chocolate and chips help give these blondies that irresistible flavour combination!

Tips for making the best white chocolate blondies

Only mix the ingredients until they are just combined. You don’t need any electric mixers here, just mix by hand until the ingredients are incorporated
Try not to overbake these blondies or they will end up dry and cakey inside!

White Chocolate Blondies FAQs

How do I know when blondies are baked?

Your blondies are baked when a cake skewer or co*cktail stick inserted into the centre comes out clean with some moist crumbs. If it comes out with wet mixture, they’re not quite done so give them a few more minutes in the oven before testing again. If it comes out completely clean you may have overbaked them so be careful!

Do I need to wait for blondies to cool before slicing?

Yes! the hardest part of making these blondies is waiting for them to cool before enjoying them. They firm up as they cool which makes them much easier to slice!

Should I store blondies in the fridge?

No, I would recommend storing them at room temperature in an airtight container. Cake tends to dry out more quickly when kept in the fridge, so keep them at room temperature for the best moist, chewy blondies.

Blondies should keep well for up to one week when stored at room temperature, though they are best eaten within 3-4 days.

Can I freeze blondies?

Absolutely – just make sure they are stored securely in an airtight container. If stacking on top of one another, use a layer of baking or parchment paper in between to stop them sticking together.

To summarise, these white chocolate blondies are:

Very quick and simple to make in one large bowl with no electric mixer required
Sweet, chewy and soft with slightly crisp, shiny tops
Full of white chocolate flavour from both melted chocolate and chocolate chips
Moist and chewy for up to one week when stored at room temperature
Great for freezing!

Equipment

12" x 9" traybake tin
Large mixing bowl
Whisk
Spatula

Ingredients

180 g plain flour
1/2 tsp salt level
300 g light brown sugar
180 g unsalted butter
160 g white chocolate chopped/broken into pieces
1 tsp vanilla level
3 medium eggs room temperature
200 g white chocolate chips/chunks

Instructions

Prepare your 12" x 9" traybake tin by lining with baking/parchment paper, or foil. If using foil, spray it with non-stick spray after lining.
Add the light brown sugar to a large mixing bowl.
Cut the butter into cubes, and either chop the white chocolate or break into pieces. Melt the white chocolate and butter together in a microwavable bowl. Microwave for 20 seconds increments, stirring in between until completely melted and smooth.
Pour the white chocolate and butter mixture into the large bowl with the light brown sugar. Whisk until combined.
Add the vanilla and then the eggs, one at a time, whisking in between each addition of egg until combined.
Add the salt and half the flour and whisk or fold together with a spatula until just combined. Add the remaining flour and repeat until just combined.
Finally, add the white chocolate chips or chunks and fold together until just combined.
Pour the blondie mixture into your prepared traybake tin.
Bake for around 25 minutes until a cake skewer or co*cktail stick inserted into the centre comes out clean with some moist crumbs. If it comes out with wet mixture, place the tin back in the oven for a few more minutes before testing again.
Once baked, place the tin on a wire cooling rack. Leave to cool completely before slicing as the blondies need to firm up to cut cleanly.
Blondies will keep well for up to 1 week when stored at room temperature in an airtight container. Best eaten with 3-4 days.
