Chocolate slice is an easy to make Australian treat, perfect to scale up for a crowd or keep it small for a few treats. It’s kind of like a cookie bar, topped with a chocolate glaze, and is sure to please.

Cafe culture in Australia 

Many cities in Australia have a big cafe culture and virtually every town has a neighborhood bakery. Both are a great place to try some tasty sweet and savory treats.

Some serve more traditional treats, while others are more creative in what they offer.

While coffee is certainly very popular in cafes, tea is also a very popular drink, as is the concept of teatime, no doubt a carry-over from the British colonial period in Australia’s history.

In fact in Australian schools, they will often talk about “morning tea” meaning morning snack.

The classic bakery items have a strong British influence as well. You’ll find almost any bakery has sausage rolls and savory meat pies, both with British origins, on the menu.

When it comes to sweet goods, while some items may have British influence, you’ll find many more uniquely Australian items, as well as influences from around the world like brownies and croissants.

The Australian slice

Many cafes and bakeries in Australia serve one or more “slices” which are a bit like cookie bars or sheet cakes. 

Some slices certainly seem to have British origins, and some like the chocolate caramel slice is essentially the same as millionaire’s shortbread, popular in Scotland (where it likely originates).

Another classic, vanilla slice, is similar to what would be known as a napoleon in the US and comes from the French mille-feuille.

The idea of a “slice”, though, is certainly very much part of Australian culture.

These days you’ll find a huge range of slices both to buy and made at home. Some are more simple and traditional, like lemon slice, but you’ll also find people getting creative with flavors and fillings.

Some believe the popularity of slices is that they are easier than making a cake but seem like you have to put in more effort than simply making some cookies. They are also perfect to make in larger quantities for things like fetes and bake sales, where they grew in popularity in the past.

This chocolate slice is one of the more traditional slices that makes a great snack for parties, or an after school treat.

Making chocolate slice

You’ll find a few different variations on chocolate slice, some of which are no bake and others baked, as this one is.

Some have a softer, fudgier base, while others are more firm. Pretty much all have a chocolate frosting/glaze on top.

This slice is easy to make as all you do is mix the dry ingredients, then separately mix the melted butter and egg then combine them.

Flatten this into the bottom of a lined dish then bake to firm it up.

Australian chocolate slice base baked

Prepare the frosting shortly before the base finishes baking and put it on while the base is still warm as it will spread more easily with the warmth.

Try not to work it too much as it will become more uneven.

You can easily scale up or down the recipe depending on how much you want. You can also cut the pieces smaller or larger to suit.

How to store chocolate slice

Any extra slice can be stored in an airtight container at room temperature for a couple days.

You can also freeze it, separating slices with parchment paper.

Prep Time 10 minutes
Cook Time 20 minutes
Total Time 30 minutes

Ingredients

For The Base

  • 1 cup all purpose flour (240g)
  • 2/3 cup desiccated coconut (44g)
  • 1/2 cup brown sugar (80g) - can also use regular sugar
  • 2 Tbsp cocoa powder
  • 1 egg
  • 10 Tbsp unsalted butter, melted (140g, 1 stick plus 2 tbsp)
  • 1 tsp vanilla extract

For The Frosting

  • 1 cup confectioner's sugar
  • 2 Tbsp cocoa powder
  • 1 Tbsp butter, softened
  • 1 Tbsp boiling hot water

Instructions

  1. Preheat oven to 320F/160C.
  2. Butter a dish or deep baking sheet/tin that's approx 11 or 12 in by 7 or 8 in and at least 1 in deep. Line it with parchment paper on the bottom and two longer sides, overhanging the sides, pressing gently into the butter to help it stick.
  3. Mix together the flour, coconut, sugar and cocoa powder in a bowl.
  4. Lightly beat the egg and melt the butter. Add these both and the vanilla to the dry ingredients and mix until well combined.
  5. Put the mixture into the prepared dish and press it down evenly, flattening the top so it's smooth.
  6. Bake for approx 20-25 minutes until the firm and the top looks dry. 
  7. Towards the end of the baking time, prepare the frosting/icing. Sift the confectioner's sugar and cocoa powder together in a bowl. Add the melted butter and hot water and mix until well combined. Add a little extra sugar/water if needed to make a semi-thick but workable mixture.
  8. Once the base is ready, top with the frosting while it is still hot. Try to spread evenly, right to the corners, but be aware if you try to work it too much the top will become less even. Once done, sprinkle with a little coconut while the frosting is still wet. Leave to cool/firm up before cutting into pieces.
  9. To cut into pieces: it's easier to loosen the short edges of the slice and lift it out of the dish in one piece. Then, cut into whatever size pieces suits (for this size, I suggest 16 pieces).

Thanks for sharing Michelle. Would you agree that while the traditional version uses this locally available ingredient, there are many different versions without it that are enjoyed in Australia currently?

I haven't made Chocolate Slice for many years, but it was one of the first recipes I learnt to make as a child. So easy and delicious!
