A classic old fashioned coconut slice recipe. The buttery pastry base is filled with luscious jam and topped with a delicious layer of toasty coconut macaroon. An iconic slice found all over Australia and New Zealand.
While in Australia we call this a coconut jam slice, in New Zealand it's called a Louise cake slice. No matter the name this is a relatively quick and simple slice to make.
It has a delicious shortbread style biscuit base using self raising flour. This gives the base a lighter texture than traditional shortbread, almost cake like.
The base is slathered in jam, raspberry, or strawberry jam as I have. It is then topped off with a gooey coconut mixture that when baked tastes like coconut macaroon.
Easy baking at its best. A recipe made from pantry staples and will fill your house with heartwarming smells. As far as slices go, this is one of the best recipes for coconut jam slice you will come across.
Pantry Staple Ingredients
A full printable recipe card can be found at the end of this post with recipe ingredient measurements and method.
The beauty of this coconut slice recipe is it uses ingredients generally found in your kitchen pantry.
- Butter: I use salted butter, but you can also used unsalted butter. Simply add a pinch of salt to the biscuit base ingredients. You can also use margarine in this recipe.
- Sugar: Caster (superfine) sugar as the smaller sugar granuals dissolve more easily when creaming the butter.
- Eggs: Bring your eggs to room temperature before use.
- Flour: Self raising flour is used in this recipe, or subsitute with plain flour with 2 teaspoons of baking powder.
- Vanilla: My preference is vanilla bean paste, but you can also use vanilla extract, or vanilla essence if preferred.
- Jam: A berry jam such as raspberry or strawberry is standard, giving a contrasting layer in the slice. You can use your favourite jam in this recipe, or try summery bourbon peach jam, or pineapple jam.
- Coconut: Traditionally made with desiccated coconut, you can also use a mix of deiccated and shredded for a more textural topping.
How to make Coconut Slice

- Make coconut macaroon topping: In a clean bowl add eggs, sugar and coconut and mix well. Spread coconut mixture over the top of the slice.
- Bake: 35 minutes or until golden brown.
- Cool: In the slice tin.
- Cut: Remove from tin and cut the coconut slice into bars or squares.
Sara's Top Recipe Tips
Cool Completely in the Tin: You may be tempted to remove the coconut slice from the tin before cooling, but it will crumble and break apart. Cool completely before removing from the tin and slicing into portions.
Warm the Jam Before Spreading: You don't have to do this step, but if you warm the jam in the microwave it will be easier to spread over the uncooked biscuit base.
Line the Tin: Even if you have a nonstick slice tin, make sure to line the tin with baking paper/parchment paper. Leave enough overhang to easily lift the slice from the tin once cooled.
Substitute the Jam: Besides the alternative jam recommendations I gave above, you can replace the jam altogether. How about a caramel coconut slice using dulce de leche? You could also try tangy passionfruit curd, or go ultimately Aussie with Tim Tam spread.
Make sure you store the slice cut into bars or squares in an airtight container.
If stored at room temperature it is best eaten within 2-3 days, if kept in the fridge within 5 days.
In summer I store it in the fridge as the heat can make it a little more moist than desired.
It does freeze, but I recommend eating it fresh within 2 days.
To freeze, wrap each bar or square individually in plastic wrap and freeze. Defrost at room temperature. Defrosted slice bars/squares can be "refreshed" in a warm oven for 5-10 minutes.
- 110 grams (4oz/½ cup) butter
- 110 grams (½ cup) caster sugar | superfine sugar
- 1 egg
- 150 grams (1 cup) plain flour

- Using either your stand mixer or hand electric beaters, beat butter and sugar until creamy and pale in colour. Add egg and vanilla and continue to beat until combined.
- Add sifted flour, baking powder and stir until completely incorporated.
- Spread mixture into slice tin evenly with a smooth surface. The back of a metal spoon works best for this. Once smooth spread jam over evenly.

Good old jam slice - so versatile. Takes me back!
That looks beautiful! I love toasted coconut and can imagine how fragrant that would be! Yummmm!
Thanks Sarah, it smelt divine 🙂
Yum! Great way to use up leftover jam when you're eager to start a new jar! Mine would be apricot!
Apricot would be pretty delicious.
Yum! This looks so delicious, like something my Gran would make! I reckon raspberry jam would be beautiful, that bit of tartness with the sweet coconut topping!
The original is made with raspberry jam and is really really good.

I love that visual of your pooches supervising your baking and subsequent photography. I have a similar problem with one of my fur-kids. One of the best places for natural light in our house is the floor in the sun room, which is very easy access for him. It is a job on its own trying to take good photos without a tail or whisker sneaking in!
Sally is really really good when I am doing floor shots, she looks on but knows not to touch the food. She really is quite amazing.

LOL! I love Sally! I wish I had your problem! Anyway, I love the slice...very "old school" and very delicious!
Was very old school and very delicious. Love having Sally under my feet, she is definitely my biggest food fan.
