1. Preheat the oven to 170C/gas 3. Butter the sides of a 20 x 20cm square cake tin and line the base with greaseproof paper.

2. Sift the flour and baking powder into a small bowl and set aside.

3. In a large bowl, cream the butter and peanut butter together until very soft. Add the sugar, egg and vanilla extract and beat until well combined. Add the flour, baking powder and the chopped chocolate and mix to form a dough.

4. Place the dough into the prepared tin and bake in the oven for 25–30 minutes, or until golden brown and almost firm in the centre.

5. Remove from the oven and allow to cool in the tin, before removing and cutting into squares.

Very quick, easy recipe! Threw this together this morning before I was due to go out and meet family.

Used traybake (long) tin, instead of cake tin, cooked for 30 mins and it turned out fabulously. I substituted a new Caramel Peanut spread I discovered in supermarket and also just threw in white choc bits. Plus added a wee bit of Rice Flour as mixture appeared a too gluggy. Slice was extremely well received. Will try next time using Caramel Choc Bits.

I've made these blondes at least 5 times now as my son adores them, but they ALWAYS sink in the middle as they're cooling :-( I've tried increasing the cooking time to 40 mins but the same thing happened. It's so disappointing as they look fab when they first come out of the oven. Does this happen to anyone else?

Totally delish...when I make a batch it doesn't last long....yum yum

These are so nice! 30 minutes is long enough. They firm up nicely as they cool down. The first time I baked them for slightly longer and they came out quite dry. When I did them for 30 mins they were yummy! I also add some nutmeg as this gives them a nice flavour.

These are gorgeous and a lovely change from chocolate brownies. I read the previous comments about timings but i found 30 minutes to be just right, although there was a bit less went into the oven cos i couldn't stop eating the dough!

I prefer these with a bit extra peanut butter, and I swap out some of the light brown for dark brown sugar to make them a bit gooier. I add a bit more vanilla and a quarter tsp cinnamon too, but that's just down to taste. A strong recipe Smile (I cook mine in a glass 8x8 pyrex and the timing is usually fine!)

VERY popular: made these for the first time on Sunday. It's now Tuesday and the first batch have gone, and the second is under siege. With our sons 'flown the nest' there are only the two of us, and my wife seems to have found a stream of friends....
Need quite a strong arm for the mixing!

Absolutely lovely. I used light brown muscovado sugar as that was what I had in the cupboard. Just had one warm with a cup of coffee - absolutely gorgeous. I halved the recipe and due to not having a small square tin, cooked in a victoria sandwich tin and then cut into wedges.

Greetings from the other side of the "pond" (California). What is it about the British cooking chefs/teachers? I want to be best friends with every one! Anyway, this Rachel Allen recipe was delicious. The texture was so moist, it reminded me of eating a peanut butter "truffle". Next time, just for fun, I will substitute milk chocolate for the white...I'm guessing it will be akin to the American candy that I've grown up with...Reeses peanut butter cups. I've been weighing ingredients as opposed to measuring for years, and finding this website....well, wow, do I feel like I'm home!

these are lovely very easy to make

Kerry-Cashman Kerry-Cashman Posted 14 Oct 2010 1:39 PM

Just waiting for these to come out of the oven... smell Lush.
But they have been cooking for longer than recommeded.
Maybe these need to be cooked on gas mark 4 for 30 mins?

RosalindT7204 RosalindT7204 Posted 06 May 2010 12:42 PM

hey i tried makin it.. hope it turns out to b gud Smile

shwetaD46896 shwetaD46896 Posted 23 Apr 2010 4:34 PM

HI these are really delicious they don't stay in the cupboard very long. they are a regular item in this house I've also made them like biscuits on flat tray. they are definitely better with crunchy peanut butter

paulineS94661 paulineS94661 Posted 17 Apr 2010 9:14 AM

just made these as a tea time treat,dead easy and very very tasty....had to cook longer and on a slightly lower heat to ensure they were cooked, but the taste was amazing !!!!

Hi Viv, you could use granulated or caster sugar as a replacement. The light brown sugar adds a richer flavour though.

Nora R Nora R Posted 15 Mar 2010 10:53 AM

is there any substitute for light golden sugar?

vivV6278 vivV6278 Posted 15 Mar 2010 7:49 AM

I just reviewed these blondies on my blog. I am in Canada and her book says to bake these at 325F and I am pretty sure that must not be hot enough because if anything, mine were under-baked! I kept them in for at least 30 minutes and then took them out and they were so moist they were falling apart but wow, were they ever delicious! I made then in honour of National Peanut Butter Lovers Day yesterday and am so glad I did. Now I am a peanut butter lover, thanks to Rachel's recipe.

I agree with the longer cooking times, also try them with macadamia nuts as well as the white chocolate they are even more delicious!!

asile asile Posted 28 Feb 2010 7:46 PM

Ive tried these scrummy blondies 3 times now, first time I read the reviews and baked them for 40 mins, that was way too long, they were dry, still tasty, but dry. The second time I baked them, again, I thought they were not ready at the time stated in the recipe, so baked them for 35min, these were much nicer, fudgy in the middle and not so dry around the edges. The 3rd time I baked them I thought blow it! and baked them for 30mins. The blondies do set and are moist, fudgy and delicious!! They do say third time lucky!!

They also needed to cook longer for me but they were very good once finished.

Weekend Carnivore Weekend Carnivore Posted 15 Dec 2009 10:53 AM

I too would say they need longer to cook - a good 40 minutes.

I used to make peanut butter cookies for my children when they were younger, I made these for my grandchildren and my daughter tried one and said how it took her back to when she was younger and how yummy they were

Beantown Babe Beantown Babe Posted 31 Jan 2009 12:27 AM

I have made these and they are great, but my boys don't like peanut butter any ideas on a substitute so there is still the chewyness?

AngelaR86772 AngelaR86772 Posted 17 Oct 2008 4:26 PM

I've baked this recipe twice now, 2 days on the trot and there is NEVER any left the whole family loves them, they are sooo moreish !!!!

NicolaH93732 NicolaH93732 Posted 13 Oct 2008 3:36 PM

i've just baked these and they are lovely very moist and doughy, but i think they are supposed to be . . .don't think they will last long when the kids come home from school!!

j49 j49 Posted 13 Oct 2008 1:51 PM

despite following recipe to the letter, my blondies took a good 45 mins, even then the middle was doughy. I checked oven temp with thermometre and 20cm tin used. Helppppp!!!!!!

annetteC29283 annetteC29283 Posted 11 Oct 2008 5:14 PM

Mmmmmmmmmmmmmmmmm, delicious. Watched the show last night and just had to make them today. Don't think they are going to last very long though - very moreish!!
