Is there a super close substitute for graham crackers?

First off, try digestive biscuits. They're really very similar cookies/crackers/biscuits, and it's a common enough substitution that it's even mentioned on Wikipedia. Cook's Thesaurus implies that they're called wheatmeal biscuits in Australia.

sourd'oh's suggestion of particularly crunchy gingersnaps might work too, but you'll also want to make sure they're not too spicy!

(Unfortunately, I don't know about specific varieties since I'm not Australian.)

I was in Australia last winter & discovered they don't sell any kind of graham wafer. I substituted the digestive cookies/biscuits and found they are not as sweet. Although the crust tasted good, the next time I made the 'graham wafer' crust, I added a teaspoon of sugar to the digestive biscuit crumbs ...now it tasted closer to the graham wafer crust I was used to.

I am an Aussie. We use Marie biscuits.

Depending on where you live, some grocer shops have an international food section. But for a crunchy sweet pie crust, I don't think you can go past a butternut snap biscuit, sold just about anywhere in Australia. I have also used Milk Arrowroot or Morning Coffee. I like these too, but they aren't as sweet.

Go to the Filipino groceries. They stock Graham biscuits. I've just bought some at Manila Mart in Ryde (Sydney) and have also seen them at Ashfield Mall in Sydney where the fruit and veg shop is run by Filipinos.

I use Grahams Crackers in my Key Lime pies. The Key Limes are specific to Florida and I bring it back with me as a juice concentrate from Publix Supermarket.

I also bring back Grahams Crackers. But when I run short there is ONLY ONE substitute in Australia. It's ARNOTT'S GRANITA. You can get it at any Australian supermarket.

Have done a blind taste test with my friends and family to see if they can taste the difference between Granita and Grahams. They can't. I give them three pieces of granita and two pieces of Graham selected randomly while they are blindfolded. NO ONE can pick the difference correctly.

I live in Australia and use Granita biscuits, mixed with 2 tablespoons of sugar, and 1/4 Cup of almond meal for my substitute to Graham crackers. All crushed together of course :)

I would assume that digesive or the suggested alternative Graham crackers would be the same as Arnott's wheatgerm biscuits or why not just use Arnott's morning coffee or milk arrowroot. I'm going to try the wheatgerm and see how that works. Most biscuit bases could use any of these three suggestions in my opinion.

I would suggest you to use Rich Tea biscuits if you find them. They are plain and they go perfect with any kind of cake

I use digestive biscuits and add cinnamon to get them closer to the taste of Graham Crackers.

I would look around the local grocer. There are many other graham products like Golden Grahams cereal, Teddy Graham snacks for kids and Annies Graham snacks, found in the organic section. Maybe you can find graham cracker crumbs in the baking section

Best substitute is digestive biscuits (sweeter and crunchier than wholemeal) look for Mcvities brand they are Scottish but available in Australia in Coles suoernarkets and other places. I use them all the time. They are great.

I think Arnotts Lattice biscuits might work well in this recipe. I will try it anyway
