Blueberry Blondies with White Chocolate Batter

Blueberry Blondie

My blueberry blondies with white chocolate batter recipe has been an absolute family favourite for at least 8 years. And that is exactly the amount of time I have known about blueberries blondies. Let me tell you how I came across them. They were just perfect for my Rainbow food – Blue series from 7 years ago.

Hey, I am a post that supports my blogging efforts, with Amazon affiliate links 😁

What are Blondies?

I first came across blondies at a nursery school function in London. Our cherubs put on a concert for us, and afterward, we were treated to tea, coffee, and cakes. My little darling, ItsNala, was only 4 years old and I was still learning on the job as a parent. Hey folks, when your kids go to school, so do you. I saw these weighty slabs of caramel coloured cake bars. As I took a bite, I closed my eyes, and thought “how on earth is this the first time I am tasting something like this and how do I experience this again?” A lovely lady, a home baker, who was setting up the morning tea explained what they were to me. They were butter-rich solid vanilla cake bars filled with white chocolate chunks!! In other words, white chocolate brownies, or simply, blondies.

How I Made My Recipe

Blondies! Wow. I wanted to make some of my own as soon as I could, forgetting that I didn’t have a baker’s bone in my body, or so I thought. Let me tell you something. I am a self-taught internet baker. Before then I wouldn’t bake to save my life. I took to the world wide web. I found a number of blondie suggestions including a whole article on the perfect blondie from none other than @felicitycloake. What I learned was you could get blondies that are fudgy, cakey, or deliciously buttery. I tried out a few recipes, I honestly can’t remember which now (I am sorry) but I eventually liked the idea of throwing in blueberries, and here is what I ended up with.

Things You Can Change With the Recipe

Over the years I have chopped and changed the recipe, sometimes dues to ease, other times due to what ingredient is available in the market. Ingredients can be exceptionally expensive, so I had to rethink using 2 whole white chocolate bars in the recipe. The blueberry blondies with white chocolate batter recipe still turns out an addictive blondie, the melted white chocolate is not necessary at all. Since moving to Nigeria I upgraded the recipe to include indigenous fruit. Agbalumo blondies were born in Lagos in 2017, thanks to… you guessed it. I decided it looked better a little browned with brown sugar but altogether it is the same blondie. The agbalumo blondie is absolutely stunning with the ruby red baked fruit contrasting brilliantly with the caramel brown. I think I should dedicate an entire post to that recipe.

Who Would Love Them The Most?

Honestly, everyone dies for these from my fussy eating kids to adults just about everywhere. I have often baked these for girls scouts bake sales only to find they are bought right off the table and kept out of sight by the teachers and parents. I have heard many a confession. Sorry kids. I have also taken these to beach get together and dinner parties. They have always been a hit no matter the event. My biggest customers are right at home. They could eat an entire brownie tin’s worth every single day if I let them. These blondies don’t last an hour in my house and I can’t blame it on my 4 kids because I and their dad have my fair share.

Future Modifications?

I love the papery thin glean that you get on chocolate brownies. My go-to recipe is the best brownie recipe by Orlando Murrin. Every now and again, I strive to get my blondie to get that film on top. Sometimes I am lucky, sometimes I am left dumbfounded as to why this achievement eludes me. It appears I am the only one who cares because no one notices. As for how quickly these disappear at school bake sales, my friend @adebworldwide can testify. She has enjoyed them time and time again.

What You Would Need to Get Now That You Might Not have!

I highly recommend this White Chocolate. It melts down well when beating it into the batter. It also holds well during baking, without turning into an oily mess all over the blondie.
I always had a rectangular biscuit tin, which I could adjust using a little trick you will see in the recipe steps. But if you need to get a Square Brownie Tin, this one has pretty standard dimensions of 8 or 9 inches.

Whisking the white chocolate with the eggs should turn out a thick and luscious custard-like mix.

I prefer white chocolate bars over chocolate chips any day, but you can use what you prefer.

If you are lucky enough to have fresh and affordable blueberries to hand, use them. I use frozen blueberries and it turns out just right too. You don’t need to thaw them out.

White blondies are great but I find a slightly tanned blondie is even better. Just substitute in a little brown sugar.

Our blueberry blondies with white chocolate batter recipe is the perfect go-to dessert for bring and share get-togethers. They always impress and I get compliments whether they are at a bake sale or in the home for tea.


  • 200g white chocolate (2 regular bars cooking chocolate, keep separate)
  • 100g butter
  • 3 large eggs
  • 3/4 cup castor sugar
  • 1 tablespoon vanilla paste
  • 125g plain flour
  • 1 pinch salt
  • 150g blueberries



1. Preheat the oven to 180 degrees celsius and prepare a 20 to 23 cm brownie tin. (I didn't have one so I would normally line my rectangular tin with greaseproof paper and use some lightly scrunched up foil to fill in the extra volume and cut it down to brownie size)


2. Cut up the butter into squares, place it into a microwaveable bowl, and microwave gently (This usually means turn on till you hear frying sounds, turn off and stir.. repeat the process).


3. Break up the first 100/125g bar of white chocolate into the melted butter, stir and place into the microwave for 20 seconds. Depending on your microwave power, 20 seconds may be too much or too little time, simply adjust to suit. Remove from oven, stir, then place back into the microwave and repeat the process till the chocolate has melted. This doesn't have to be perfectly smooth. Set aside.


4. Whisk the eggs, sugar, and vanilla until smooth and creamy. Add the warm melted buttery chocolate lava and continue to whisk till it looks like custard.


5. Cut and fold the flour and chopped white chocolate pieces into the batter. Pour the batter into the baking pan. Top with the blueberries. You may push a couple into it, but not too much.


6. Bake for 40 minutes till blonde 🙂 Allow to cool in the tin before removing and cutting into brownie sized rectangles.
