These decadent, American-style dessert bars are the fairer cousin of the brownie, with the same dense and fudgy texture

  1. Grease a 21 x 21cm brownie tin with a little butter, then line the base and sides with baking parchment. Place the butter and 100g white chocolate in a bowl, suspended over a pan of gently simmering water. Stir every few mins, until the butter and chocolate have melted. Remove the bowl from the pan and leave to cool for 15 mins. Heat oven to 180C/160C fan/gas 4. Combine the flour and baking powder in a bowl, with 1/4 tsp salt.

  2. Place the sugar and eggs in a large bowl. Using an electric hand whisk, beat the mixture until it looks thick and foamy – this will take a few mins. The egg mixture is ready when it leaves a trail from the beaters, which sits on the surface for 2 secs.

  3. Add the vanilla to the melted chocolate and give it a good stir – don’t worry if it has separated. Pour into the whisked eggs and sugar. Use a spatula to gently fold everything together, until most of the buttery streaks have been folded in. Sieve the flour mixture into the bowl and fold together again, add the remaining chocolate chunks and stir until well combined.

  4. Pour the mixture into your tin, smoothing it into the corners. Bake for 30-35 mins, a skewer inserted to the centre should come out with sticky crumbs, but no raw cake mixture. Cool completely in the tin – the blondies will sink in the middle as they cool, just like brownies. Cut into 16 squares. The blondies will keep for 5 days in a sealed container.

Everyone saying that it’s still raw, I’m not sure why you didn’t just cover the top with baking parchment and continue cooking until fully cooked. Everyone’s ovens are different so cooking times a guideline with all recipes

Turned out nice for me. I can see how they might have ended up greasy though and they were slightly gooey (in a nice way, but I do always worry a little about giving them to people like that, probably wrongly, as that's how some cafés serve them). I went with 170-80ish rather than 160 degrees (fan oven).

Ps ithink the biggest problem with this recipe is beating the eggs and sugar, it is unnecessary and just leads to it being harder to blend the other ingredients into the mix. The brownies will rise, regardless of eggs being whipped and ultimately brownies should be dense not light.

I just can’t believe people throw away perfectly good food simply because it has not cooked fully. Use your brains, i too only read these comments after the cake was in the oven, and it too was raw, so what did i do? Took it out, greased and lined a larger tray and plonked the mixture in that and spread it out. Perfectly edible within another 15 minutes. SOmetimes i think what is the world coming to we can only follow instructions and not use a bit of common sense!

Awful recipe, one of the worst I’ve tried. Don’t bother

I gave them 50 minutes in the oven at the recommended temperature and they are raw in the middle. Very disappointing.

I agree with the other comments and wish I’d read them before trying it! Baked for 35 mins and left to cool. Centre was still raw. Waste of time

I wish I'd read the comments before making these, as fully agree they didn't fully cook and wouldn't have wasted my time. They were baked on top but then the mixture below had sunk to the bottom of the pan and was raw. underneath.

Some comments were saying the brownies were greasy. White choc has a lots of cocoa butter in it so I added about 50g less butter. I also put it in a 20cm by 30cm tin rater than 21. Then I added chopped up cruchie bars as they are my favourite chocolate bars. They turned out great. Maybe cook for about 3/4 less minutes as well as mine were a bit overcooked after 30

Absolutely dreadful, waste of time effort and money. Raw and won't fully cook, greasy, with burnt crispy edges. Avoid at all costs!
