Delicious and easy Oat Slice, so lovely and versatile using pantry basics
Published May 11, 2021, Updated April 5, 2024
Variations of this recipe can be found everywhere, it is a classic slice that is just so easy to make! I like to think of it like a giant cookie. So flavoursome!
I have refined mine over the years to include some flavours the kids and I like. I add a little vanilla and golden syrup to mine because I find that just works so well with rolled oats which isn’t in the original recipe.
The method for this one is so easy, simply adding the dry and wet ingredients then baking. You can choose to have a thin slice or thick depending on the size of the baking tin you use.
I like mine to be thick, but if you were using these for lunch boxes you might like a thinner slice to create bars.
The original recipe I have for this uses sultanas, and they would be lovely. So would dried apricots or cranberries if you are so inclined! I just add extra chocolate drops and there are definitely no complaints!
The ingredients are pantry basics

I love using rolled oats or old fashioned oats in baking. I prefer to use rolled oats rather than quick cooking oats in for better results.
I have several rolled oat recipes so far on the blog, if you are inspired to try them check them out below by clicking the title link.
Rolled Oat Crunch Slice
Apple, Banana & Carrot Rolled Oat Muffins
Rolled Oats & Apple Breakfast Cups
Anzac Muffins with Caramel Filling
Anzac Slice
Anzac Biscuits
I am sure there are more but that is a small selection of some of my favourites. Having rolled oats as part of your pantry basics is a great idea as they help to bulk out your recipes and add a lovely subtle nutty flavour.
With this recipe you simply combine all of the dry ingredients then add the melted butter and other wet ingredients to this and press it into a lined tin.
You want to bake this until it is golden brown and it will smell delicious. It is quite like a large cookie once baked. Ideally you will want to allow it to completely cool in the tin before trying to slice it so that it holds together.
Stored in an airtight container this should last for at least 4 days.
I really look forward to hearing what you think of this one. I love sharing all of these simple recipes, I hope my blog is like a big cook book for you to come to when you have a pantry of ingredients and wonder what to bake today!
This is for when you have rolled oats and chocolate in the cupboard and feel like something tasty
Onto my recipe for Easy Oat Slice
Easy Oat Slice
Delicious Oat Slice, so easy to make with lots of chocolate drops
Ingredients
- 1 Cup Plain White Flour (150 grams)
- 1 Cup Rolled Oats (85 grams)
- 2/3 Cup Desiccated Coconut (55 grams)

- 1 teaspoon Baking Powder
- 1 Cup Chocolate Drops or Chips (180 grams)

- 1 Egg, Large
- 1 teaspoon Vanilla Essence
- 2 Tablespoons Golden Syrup
- OPTIONAL
- 1/2 Cup Sultanas or Dried Fruit
Instructions
- Preheat oven to 180C, Bake
- Line a 20 cm square tin* with baking paper. I like to lightly spray the tin with cooking oil before to help the paper stick
- In a medium bowl add the flour, rolled oats, coconut, brown sugar, baking powder and chocolate drops and stir to combine
- In a small bowl melt the butter in the microwave in short bursts, then add the egg, vanilla and golden syrup and whisk to combine
- Pour this into the dry ingredients and stir until fully combined
- Spoon into the prepared tin and press until evenly spread
- Bake for 25 minutes or until golden brown
- This slice will firm upon cooling so leave to cool completely in the tin
- Remove from the tin once cold and slice into squares
- Store in an airtight container
- Enjoy!
Notes
Tin Size
I have used a 20 cm square tin, if you prefer thinner bars use a 23-25cm tin and cook for less time.

Looks delicious and I’m keen to try it. The munchkins love the chocolate weetbix slice last week.
Sharon says
I made this today and swapped out the choc drops for half a block of whittakers milk choc chopped up and added chopped dried apricots, it is amazing!
Abby says
I’ve made this twice now and it’s such an amazing slice! Beautiful taste and texture. Thank you!
Anna From Just A Mum says
Thanks for the fantastic feedback! Anna
Ravine says
Hi,
Made this and whilst tasting lovely, it came out dry and brittle/crumbly. Where did I go wrong?
Thanks in advance.
Tracey says
So easy, quick and really tasty! Will definitely make it again and I love how it would easily work with all kinds of different dried fruits or choc bits. Thank you!
Anna From Just A Mum says
I’m so delighted that you enjoyed it! Anna
Jane says
Will omitting the coconut from the recipe affect it much or do I need to substitute something else? Thanks!
justamumnz says
It does affect the outcome as it can change the dry to wet ratio. The two possible substitutes are a little extra oats or crushed nuts.
Lucy says
Do you think LSA would work as crushed nuts? As coconut alternative?
justamumnz says
I’ve not tested it with LSA but ground almonds or ground oats can also work so LSA could definitely be worth a try ☺️
Sall says
Is it possible to not use the coconut and if so what {nut free} would you substitute it for?
Peter Anson says
I’ve made it several times. Very tasty. I prefer substituting chopped dates for the chocolate drops.
Joy Coyle says
Delicious! I added some chopped dried apricots. .
Beccy says
Absolutely love this recipe – best muesli slice recipe I’ve found yet! And it’s so easy to make! I make up batches of the dry ingredients in jars and store til needed. Could you substitute the butter for oil to make it cheaper & dairy free? If so how much should I use?
Julie Andrea says
If you want to reduce the sweetness, you could use semi-sweet chocolate chips and unsweetened coconut, also reduce the brown sugar just a touch and same with the golden syrup, reduce it a bit .. with all that, the sugar content would be lower. Raisins are also very sweet, you could sub a different dried fruit or finely chopped apples .. blueberries even!
Julie Andrea says
Oh these came out just perfect! I doubled the recipe and used a 9 x 13 metal pan, lined with parchment paper. The raisins and dried cranberries were simmered in orange juice to plump them up, I used 1 cup of white and 1 cup milk chocolate chips and an extra little egg that I wanted to use up (farm eggs, all different sizes) also .. Vanilla Paste instead of Vanilla extract and substituted Corn Syrup for Golden Syrup (I might try maple syrup next time) and .. 1 heaping teaspoon of cinnamon and freshly grated nutmeg. I topped the entire thing with 1/2 cup of hemp hearts, just sprinkled on top – adds protein and terrific flavour.
I will be making these again! They are perfect for my elderly mum to have for breakfast (instead of prepackaged cereal bars) or dessert with some whipping cream poured over or ice cream. Thank you.
April says
Reduced the sugar by adding dates, I pre soaked dried dates to soften, then added in, lovely.
Rachael says
Just put this in the oven, nice easy recipe but the batter was very sweet almost over bearing, hopefully its better when cooked?
Lesley Broughton says
Does it have to be plain flour and baking soda can I use self raising flour
justamumnz says
Yes you can replace with one cup of self raising flour, but there is no baking soda in this one.
Polly says
I made this slice today and it is absolutely beautiful. I added a packet of dried cranberries as well. Couldn’t resist having a piece just out of the oven.
Fiona says
This is my son’s absolute favourite slice and the only things that definitely disappears from his lunchbox. I must have baked it 30 times during lockdown. I have substituted gluten free flour for normal flour and it still works perfectly. Thank you for sharing the recipe with us.
Catherine says
I didn’t have any chocolate chips so I substituted dates and added some cinnamon and nutmeg – delicious! I’ll certainly be making this recipe again – thank you!
justamumnz says
Great! So glad you enjoyed it.
Elizabeth Hanna says
Purely delicious ?
Latesha says
Delicious!! Added white choc chips too (as didn’t have enough milk choc), chopped apricots, and a tsp of chia seeds (we’re a bit chia obsessed atm). Sooo yummy hard not to eat it all at once!
Bev Laffer says
Love your recipes Anna. The oat slice sounds great – just need to know if your oven temperatures are for fan forced ovens or conventional?
justamumnz says
Conventional Bake
