No bake desserts. They’re up there with some of my favorite things to make.

There’s very little mess left over, they usually require minimal ingredients and there’s less chance of things going wrong!

Baking can sometimes be a tricky thing to master but with no-bake desserts, you just chuck everything in a bowl, whack it in the fridge for a few hours and you’re done. Perfection.

This Oreo tiffin recipe is no different! It contains just 6-7 ingredients and aside from chilling time, it takes around 20 minutes, tops, to make!

The ingredients you’ll need for this recipe are:

  • Oreos (of course)
  • Digestive biscuits (or if you can’t find those where you live, you can use any other plain type of biscuit/cookie such as shortbread or Graham crackers)
  • Unsweetened cocoa powder
  • Agave nectar (this can be subbed for maple syrup or any other liquid sweetener that you like)
  • Vegan chocolate (I used a mix of white and dark chocolate because I liked the way it looks, but you can stick to just one type if you’d prefer!)

What is Oreo Tiffin?

Tiffin is a dessert that originated in Scotland, my home country! It’s also known as fridge cake because you don’t need an oven to make it- just a fridge!

Tiffin typically consists of crushed biscuits, chocolate, and some sort of fruit like raisins and/or cherries.

Basically, it’s a bit like rocky road but without the marshmallows. I have a traditional Scottish tiffin recipe on the blog too!

Personally, I am not the biggest fan of fruit and chocolate together so I didn’t include raisins or cherries. If you like them, of course, you can totally add them!

Technically, I should have named this recipe Oreo fridge cake because I didn’t make it the traditional way with fruit. But to me, tiffin is tiffin so that’s what I’m going with!

If you like, you could add some chunks of vegan white chocolate instead. It would give an extra bit of sweetness and texture without taking away from the chocolatey flavor!

Even without any chocolate chunks or fruit, this Oreo tiffin will still be amazing! As long as you’ve got the rest of the ingredients, it will taste delicious.

How to make Vegan Oreo Tiffin

Step 1:

The first step to making this tiffin is to line an 8×10-inch rectangular pan with baking paper.

You can use any square or rectangular pan you have handy but bear in mind this will change how thick/thin the tiffin is.

Step 2:

Two of the main ingredients in this recipe are crushed Oreos and crushed Digestives, so now is the best time to do this.

Place 2 packs (28 Oreos) into a large bowl along with 4 Digestive biscuits. I like to keep 2-3 Oreos aside for crushing on top but this is optional.

Use the end of a large rolling pin to crush the cookies into large chunks. You don’t want them to be super fine.

Having a few crumbs and a few larger chunks will work best. See the image below for reference if you’re not sure.

Crushed Cookies In A Bowl

Note that if you don’t have Digestive biscuits where you live, you can substitute them for any other plain biscuits or cookies such as shortbread, Graham crackers* or even just some more Oreos!

*Make sure the Graham crackers you use are vegan-friendly, such as the Nabisco brand.

Step 3:

Place 120g (1/2 cup) of vegan butter into a pot along with 2 tablespoons of unsweetened cocoa powder and 3 tablespoons of agave nectar or maple syrup.

Place the pot over medium-low heat and stir gently until the mixture is smooth.

Chocolate Mix In A Pot

Step 4:

Now add 100g (3.5oz) of vegan chocolate to the pot and keep stirring gently until there are no lumps of chocolate left.

Remove the pot from the heat.

Step 5:

Pour the melted chocolate mixture into the bowl with the Oreo and Digestive chunks and give everything a good mix until everything is well coated.

Step 6:

Spoon the mixture into your lined tin and use the back of a spoon to press it in firmly.

Biscuit Base Pressed Into Tin

Place it in the fridge while you prepare the topping.

Step 7:

Melt 100g (7oz) of vegan dark or milk chocolate in a small pot over a low heat, and 100g (7oz) of vegan white chocolate in a separate pot. Stir gently until there are no lumps left.

Remove the biscuit base from the fridge and pour the milk/dark chocolate over it. Spread it out to the edges using the back of a spoon.

Now pour the white chocolate over in a drizzling motion, and tip the tin to allow it to spread out a little. Then use a fork or a toothpick to create a marbled effect.

Step 8:

Crush the few remaining Oreos on top of the melted chocolate if you wish and place the tiffin into the fridge for 3 hours before cutting into squares!

How many people does this recipe serve?

This recipe is very rich so a little bit will go a long way! If you want large, chunky slices it will serve 12-16 people.

Personally, I think a 24-serving-sized piece is a perfect balance. It’s not too sickly but not too little either.

If you prefer bite-sized chunks it can serve up to 48 people. It all just depends on your preference and how much of a sweet tooth you have.

How to cut tiffin

On my first attempt at making this recipe, I made a complete mess when trying to cut it into squares. The chocolate cracked and moved around and I ended up having to slide it back into place.

It wasn’t pretty.

The next time I made it, I warmed my knife up to help melt the chocolate ever-so-slightly before cutting into it.

To do this, you just need dip a sharp knife into hot (boiling) water, very quickly dry it off with a towel then cut your squares.

Cutting the Oreo tiffin into squares

Make sure to wipe off any excess chocolate from the knife in between each slice.

You can pre-score lines into the tiffin beforehand to make it easier too.

How long will this Oreo fridge cake last?

The great thing about chocolate tiffin is that it lasts for ages! Kept in an airtight container in the fridge, this will stay delicious for at least a week, but probably longer!

It also freezes beautifully too so you can make it ahead of time if you’d like. If you want to freeze it, allow it to set then remove it from the tin. Wrap it up tightly in plastic wrap, place in an airtight container and freeze for up to 2 months.

You can freeze the whole thing or individual slices.
