Easy Chocolate Slice

A super easy chocolate slice with chocolate icing and sprinkles... a good old fashioned favourite with the kids (and adults too!).

This easy chocolate slice would have to be one of the all-time favourite recipes in our house! I used to make it with my Mum when I was little... and I now I make it with my own son. It's just one of those classic slices that you can make a million times over - and it's still just as good!

A melt, mix and bake slice...

You know how much I love a simple recipe, right? Well this is exactly that!!!! In just a few simple steps (and with a few basic ingredients), you'll have a delicious chocolate slice with icing!

1. Melt the butter
2. Add the wet ingredients and mix
3. Add the dry ingredients and mix
4. Bake in the oven

Seeeee... so, so easy!

How To Make Chocolate Icing

This classic chocolate icing recipe is so simple. It's made from:

• icing sugar
• butter
• cocoa
• boiling water 

... and takes just a few seconds to whip up. (It's the same icing that we use on our most popular chocolate coconut slice recipe too!)

Thick Chocolate Icing

If you like your icing to be thick, simply add a little more icing sugar and a little less water. Use pure icing sugar for a chocolate icing that sets firm. 

Soft Chocolate Icing

If you prefer a runnier style of icing, add a tiny bit more water (but not too much!). Use icing mixture for a soft icing that doesn't set firm. 

Chocolate Slice Conventional Method Vs Thermomix Method

It's no secret how much I love my Thermomix and I've made this slice in there wayyyy too many times to count. But it's honestly just as easy to make the conventional way

Both ways use:

• 1 bowl

And require:

• no-fuss

Winner, winner! I've included the recipe cards for both Thermomix and conventional methods below so you can use whichever one you like!

Storing Chocolate Slice

This slice can be stored in the fridge or in a cool place at room temperature for up to 5 days.

Alternatively, it can be frozen for up to 3 months.

Notes

RECIPE NOTES & TIPS

Equipment - this is a super easy one bowl recipe. All you need is a bowl, a spoon, a baking tray and an oven. You can also prepare the base and icing in a Thermomix. Both methods are included above. 

Icing sugar - for thick and firm icing, use pure icing sugar. For a soft icing, use icing mixture. If you're planning to use the slice in lunch boxes, I recommend using pure icing sugar.

Runny vs. thick icing - if you like your icing to be thick, simply add a little more icing sugar and a little less water. If you prefer a runnier style of icing, add a tiny bit more water (but not too much!).

Storage - This slice can be stored in the fridge or in a cool place at room temperature for up to 5 days. Alternatively, it can be frozen for up to 3 months.
