Mocha Slice


This is another one of my Grandma’s classic recipes. I made it on the weekend and took it to share with the family after we watched her house sell at auction.

It was a great auction and it will be hard to say goodbye to a house that is full of so many happy memories (not to mention her amazing new kitchen- you might have seen it in this post.)

As this is Dad’s favourite sweet recipe of his Mum’s, I thought it a good one to post following Mothers’ Day.

You’ll need

For the base:

  • 1 cup self raising flour, sifted
  • 1 cup rolled oats
  • 1 cup dessicated coconut
  • 1 cup firmly packed light brown sugar
  • 2 tbsp cocoa or cacao powder
  • 100g butter, melted
  • 1 egg
  • pinch of salt

For the icing: 

  • 1 heaped teaspoon of instant coffee dissolved in 60ml of boiling water
  • 15g butter, melted
  • 1 cup icing sugar, sifted
  • 2 tbsp cocoa or cacao powder, sifted


1. Preheat oven to 180°C and line a standard rectangular slice tin with baking paper.

2. Mix dry ingredients in a large bowl.


3. Add butter and egg and stir until completely combined. Press into the prepared tin and smooth with the back of a metal spoon.


4. Cook slice for 15-20 minutes, it will harden on cooling so keep an eye on it and test to check whether it is becoming hard after 10 minutes in the oven.

5. While the slice is cooking, make your icing by mixing all together all of the ingredients in a small bowl. It should be reasonably runny, with a similar consistency to melted chocolate.

Questionable photography skills that day.

6. Remove the slice from the oven and allow to cool slightly for five minutes. Pour the prepared icing over the still warm base and spread evenly. Cool in tin until the icing has set to a glossy finish and slice.

You can also sprinkle some extra cacao powder and roughly ground coffee beans on top to add a bit of extra oomph to the presentation if you so desire!

Let me know what you and your taste testers think of this one.

The below photo says it all for my place- I had set up my slice to take photos, went away for five minutes and came back to find my most attractive piece missing. Dad had unknowingly devoured it!
