    Peanut butter starts with dry roasting peanuts, which concentrates and heightens their flavour…

  • 200g bar dark chocolate, broken into pieces

    Dark chocolate means the shiny, dark-reddish brown treat produced from the cacao bean, theobroma…

  • 280g soft light brown sugar
  • 3 medium eggs
  • 100g self-raising flour


  1. Set aside 50g each of the peanut butter and chocolate. Heat oven to 180C/160C fan/gas 4 and line a 20cm square baking tin with baking parchment. Gently melt remaining peanut butter, chocolate and all the sugar in a pan, stirring occasionally, until the sugar has just about melted. Turn off heat and use a wooden spoon to beat in the eggs one by one. Stir in the flour and scrape into the tin.

  2. Melt reserved peanut butter in the microwave on High for 45 secs, or in a pan, until runny, then drizzle over the brownie. Bake for 30-35 mins until it has a crust, but the middle still seems slightly uncooked.

  3. Melt reserved chocolate, drizzle over the brownie, then cool in the tin before cutting into squares.

Very easy to bake, I actually cut the sugar down and drizzle chocolate at the end by 20g. I didn't add the left over chocolate to the mix but next time I will. It makes the most chewable and moist brownies I've ever tasted. Next time I make then I'm going to drizzle a combination of white and dark chocolate to improve the finished pattern.

These were delicious and the peanut butter flavour was awesome. My only criticism was that I found the brownies a tad bit too sweet. Next time I prepare, I will reduce the sugar added (as suggested in the comments). I will also use a darker chocolate (perhaps 84% cocoa) to counteract the sweetness. I used crunchy peanut butter and the nuts added great texture. Definitely a ''chewy, fudgey brownie'' as opposed to a ''cake type brownie''. Baking time was 25 minutes.

I had the ingredients in the cupboard so thought I would give this a go as I love making brownies but hadn't tried it with peanut butter. I didn't have a 20cm tin only a 19 and a 21cm tin so I thought it best to use the 19cm. I baked the brownies for 32mins and they were perfect! Yum yum!

I saw these and craved them, so went out and bought all the stuff. Then realised I had forgotten the sugar so I just used demerera sugar instead. It didn't seem to melt in that well in the pan but when I baked it, it worked out just fine. I used a combination of dark and milk choc (as I am not a big fan of dark). They worked great, didn't last long, oops! Suggestion - I would use smooth PB rather than crunchy, personal taste?!?

I made this for my grandson for his first communion party. He loves chocolate brownies and loves peanut butter BUT the recipe did not work I bought the usual peanut butter, but it did NOT MELT! I was left with a very stiff mixture of sugar, peanut butter and chocolate. All the chocolate had melted, but the suger needed more fat to melt properly, which the peanut butter did not provide. I managed to beat in the eggs but was unable to melt the peanut butter to drizzle on top of the mixter, and resorted to putting half teaspoon blobs on the top, which didn't melt in the oven either. Unless you can suggest a make of peanut butter (other than Sunpat which I used), then this recipe is a disaster.

this is what happens if you use good quality PB. try the ones with added oils melts better in the microwave.

Not sure where you can shop as not sure where you live but I used Aldi specially selected have used both crunchy and smooth of this brand and worked well each time have made this recipe 3 times and has been perfect each time personally prefer it will smooth in the brownie mixture and crunchy melted on the top. I would imagine any supermarket own brand would work aswell. Hope this helps.

I used smooth peanut butter and 50 g less sugar and it came out great. Also did one with crunchy slightly different flavour but all got eaten. Very easy recipe.
