Burnt Butter Caramel Slice

by | Sep 15, 2011 | 37 comments

Whenever we have after-school playdates or end-of-the-year class and office Christmas parties and everyone has to bring a plate, my boys and Nick take a box of these decadent Burnt Butter Caramel Slice to the soiree! A twist on the classic Chocolate Caramel Slice, this delightful afternoon treat was created as a result of a kitchen mishap. It is so incredible, this Burnt Butter Caramel Slice must be baked!

A delicious twist on the classic Chocolate Caramel Slice

Burnt butter has always had a fancy-schmancy ring to it for me. I have never tasted anything burnt butter, at least not anything that was pre-meditated. And that is exactly what happened when I set out to make this slice earlier this week. My goal was to make a classic chocolate caramel slice. That was pre-meditated. What happened after that wasn’t.

A chocolate caramel slice is one of the simplest sweet treats you will ever make and it is addictive and thoroughly fantastic. It only has three steps and if you follow them, you are golden. A no-brainer really. The first is a cookie layer that is baked for a set amount of time, the second is a caramel layer that is baked for a set amount of time. The third is a chocolate layer that is just poured over and left to set. But when you botch up layer number two, as I did, then you get Burnt Butter Caramel Slice. And it is far more divine than any Chocolate Caramel Slice I have ever tasted! So hooray for happy accidents!

Please pay heed to the size of the slice container and the baking times. The size is important to get the right height for the slice and the timing is important so as to not burn the caramel. You just want to bake it long enough to get those dark burnt bubbles on top. The recipe can be easily doubled or tripled. I hope you make these and love them!

Prep Time: 15 minutes
Cook Time: 35 minutes
Servings: 15 pieces


for the cookie base

  • 1 cup plain flour
  • 1/2 cup desiccated coconut
  • 1/2 cup brown sugar
  • 125 g butter, melted

for the burnt butter caramel topping

  • 1/3 cup golden syrup
  • 125 g butter, melted
  • 1 X 400g can sweetened condensed milk


  • Preheat oven to 180°C (350°F) /160°C (320°F) fan-forced. Grease and line a 20 x 20cm (base measurement) square slice tin or a 27.3 x 17.5cm (base measurement) rectangle slice tin with baking paper hanging over the edges.
  • Place flour, sugar, butter and coconut in a bowl and mix well. Press the mixture thinly into the bottom of the prepared tin. Bake in the pre-heated oven for 15 minutes until golden. Remove from oven and cool for 15-20 minutes.
  • Place the condensed milk, butter and golden syrup in a saucepan over very low heat. Stir constantly to avoid sticking and cook for about 5-7 minutes until the caramel has thickened and is smooth. If you feel that the butter rises to the top, remove from heat and continue mixing until smooth and creamy.
  • Pour caramel mixture onto the baked cooled cookie layer. Bake in the oven for 18 to 25 minutes until the caramel is golden and starts browning in spots (burnt butter effect!). (I start watching the top from the 15-minute mark, if it is starting to brown very quickly, I take the slice out of the oven)
  • Remove from the oven when you see it starting to brown on top. Cool for a couple of hours until firm and then slice and serve. Alternatively, wait 15 minutes until cooled slightly before slicing.

    Hi, I live in Texas. I am not sure what golden syrup is. If it isn’t available in the states. ..could you suggest a subdtitute? These look delicious. Thanks

  24. Kay

    Just read the above comment & I too would love to know what golden syrup is???? Thanks so much & I look forward to hearing your reply!! Smiles, Kay

  25. Maggie

    Perhaps “golden syrup” is the same as corn syrup?

  26. Sneh

    Hi guys, perhaps this might help


    That link shares several recipes on how to make golden syrup at home. It is sticky and thick like treacle, the colour of maple syrup. It has a very caramel taste. Can be substituted with honey or maple syrup but the taste won’t be the same. Cheers!

    Holy shit. You’re probably sick to death of people telling you how friggin’ amazing this recipe it is but I don’t care, I’m telling you anyway! I made these last night , photographed and blogged about them this morning. My post is full of links pointing straight back to you! I am eternally grateful 🙂

  28. Nerida

    I made these for my Grandma’s 92nd birthday. They are amazing!! My cousins are the whole tray in 5 minutes.

  29. Sarah

    I just tried these after David Leibowitz linked to them on FB. I sprinkled a bit of salt on top before baking, and they are seriously amazing. I think my colleagues will be very appreciative tomorrow.

  30. Amber

    Such a tempting and beautiful recipe!

    Is it ok to skip the golden syrup? Can’t find it at where I am.

    • T

      Uhm, no. Of course you can’t skip it. If you’re in the U.S., just use corn syrup.
