Golden Oreo Blondies

I’ve just got back from a weekend away in West Wales. The occasion was our friend’s 30th birthday, and 14 of us rented out a large house in a little village called Aberdovey. It was such a beautiful place full of lambs frolicking in the fields, quaint houses painted in bright colours and gardens filled with wild flowers. I’m such a city girl and sometimes I find the countryside quite daunting as I don’t really understand it. I’m so used to convenience, modern technology and city life. But I really enjoyed myself and would definitely go back! I wanted to take along some treats for everyone and I found a blondie recipe in Olive Magazine, that used custard creams which I made a few weeks ago. This time I went for golden oreos and they didn’t stick around for long!

I started by melting 175g butter, 200g light brown sugar, 125g golden caster sugar and 4 tbsp custard powder on a low heat.

I let it cool for 5 minutes then whisked in 2 eggs and 2 tsp vanilla extract.

I broke up the golden oreos. I used 18 of them.

I added a pinch of salt, 250g self raising flour, 150g white chocolate broken into chunks and a third of the biscuits.

I poured the mixture into a lined baking pan and sprinkled the rest of the biscuits on top.

I baked the blondies on 180C/160C Fan/350F/Gas Mark 4 for 30 minutes. I left them to cool in the tin.

I removed them and sliced them up. They were so sweet and gooey, and every other bite you come across a chunk of white chocolate or a piece of golden oreo. They went down really well with everyone this weekend!

I am entering these into myself and Cakeyboi’s challenge Treat Petite, where the theme is favourite biscuits, sweets and chocolates.

    I've stayed near Aberdovey before. It certainly is beautiful round there and really close to one of my favourite places…. Borth! Sounds like a great weekend. x
