If you love a good homemade gift, my Cookies in a Jar is just as easy and gorgeous, and this Chocolate Rocky Road is another classic that always goes down a treat.

I make them year-round - for teacher gifts, end of year presents, birthdays, or just a "thinking of you" surprise. Building a homemade hamper? They pair beautifully with my easy Caramel Fudge, a batch of 3 Ingredient Shortbread or some Bounty Balls.

Brownies In A Jar Ingredients
Just a handful of pantry staples - here are the key things to know:
Note: Scroll to the recipe card at the bottom for the ingredients quantities and full detailed method.
- Cocoa powder - use a good-quality cocoa for the richest chocolate flavour. Dutch-process or regular both work.
- Brown sugar - this is the secret to fudgy brownies. It adds moisture and that classic chewy texture, so don't swap it out for more caster sugar.
- Chocolate chips - I love using a mix of milk and white for contrast, but use whatever you prefer. Dark chocolate chips give a richer, less sweet result.
- Walnuts - totally optional but they add a lovely crunch. Leave them out if you're gifting to someone nut-free.
Variations
- Nut-free - simply leave out the walnuts or replace with extra chocolate chips.
- Gluten-free - swap the plain flour for a good quality gluten-free plain flour blend.
- Triple chocolate - add dark chocolate chips or chunks alongside the milk and white for extra richness.
- Festive twist - swap the walnuts for M&Ms or roughly chopped candy canes for a Christmas version.
How To Make Brownies In A Jar
It is SO easy. Grab a clean jar, layer in the dry ingredients, print the tag - and that's literally it!
Note: Scroll to the recipe card at the bottom for the ingredients quantities and full detailed method.
- Prepare the jar and dry base: Use a clean 1-litre glass jar. Combine flour, salt and baking powder in a bowl and mix well.
- Start layering: Add half the flour mixture to the jar and level it out. Spoon the cocoa powder evenly over the top.
- Add the remaining flour: Gently spoon the rest of the flour mixture over the cocoa and smooth it out.
- Continue layering: Add the brown sugar, then caster sugar, then chocolate chips, then walnuts on top.
- Seal and decorate: Close the lid tightly and attach your printable gift tag with a ribbon. Done!
- Baking instructions for the tag: Empty jar contents into a bowl, add 150g melted butter and 3 eggs, mix well, then bake in a lined slice tin at 170°C for 25-30 minutes.
Recipe Tips
- Use a wide-mouth jar - so much easier to layer neatly, and they look better too.
- Making multiple jars? Scale up your dry ingredients and line the jars up in a row. Add one layer to all the jars at a time - a little production-line-style. So satisfying.
- Gently tap the jar on the bench between each layer to keep everything level and defined.
- Wipe the inside of the jar between layers with a dry paper towel to keep the layers crisp and clean.
- Don't skip the brown sugar - it's the key to fudgy (not cakey) brownies.
- Got extra room at the top? Just add more walnuts or a few extra chocolate chips to fill it out.
- Pairing ideas: Bundle the jar in a hamper with my Caramel Fudge or 3 Ingredient Shortbread for an impressive gift basket.
- Store the sealed jar in a cool, dry place for up to 3 months.
- Once baked, brownies keep in an airtight container for 3-4 days.
- Freeze baked brownies for up to 3 months - slice them first for easy grab-and-go portions.

Brownies In A Jar FAQs
The dry mix will keep for up to 3 months stored in a cool, dry place with the lid tightly sealed. Just make sure there's no moisture getting in and it'll be good to go whenever the recipient is ready to bake.
A 1-litre clear glass jar is perfect - it fits all the layers neatly and shows them off beautifully. Wide-mouth jars are the easiest to fill. You'll find them at Kmart, Big W or most discount stores for just a few dollars.
Absolutely! Just leave the walnuts out entirely or replace them with extra chocolate chips. Great option if you're gifting to a nut-free household or a school.
So many options! My Caramel Fudge and 3 Ingredient Shortbread are both easy to make and look gorgeous alongside the jar. Add some nice tea, a wooden spoon, a tea towel and you've got yourself a beautiful homemade hamper.

Do you have the conversion for the butter when making? 150 g melted appears to be 10 tablespoons on conversion charts but want to make sure I am writing directions clearly.
Lucy says
Yes you are correct 🙂

Lucy says
