Biscotten torte, often known as rum torte cake, is a style of fridge cake. It is a delicious dessert that is prepared up to 24 hours in advance. This is an easy and delicious make-ahead dessert with layers of almond cream and rum.
This recipe is close to my heart and has been a staple for over 35 years. A dessert my mum made for as long as I can remember. It is the most requested cake I make for the family.
It was my mum's mid-week dinner party dessert. She served it to guests with a slice missing. Her reasoning to guests was that it looked better when you could see the layers.
In truth, it was to make sure that a slice was saved for me to eagerly devour the next day. Except for that saved slice the whole dessert would be polished off in its entirety.
It's fail-safe for easy entertaining and can be prepared up to 24 hours in advance (or 48 undecorated). Trust me, give this one a go!

Ingredients
A full printable recipe card can be found at the end of this post with recipe ingredient measurements and the method.
- Ground Almonds: Also known as almond meal. Buy it prepared, don't grind your own almonds.
- Biscuits: I use Arnott's Nice biscuits. Which is pronounced: "neece or nise". You could substitute these with a plain rectangular milk coffee biscuit.
- Caster Sugar: Also known as superfine sugar, a sugar that has finer granules than standard sugar. The finer sugar dissolves and melds with the other ingredients.
- Eggs: The eggs in this recipe aren't cooked. Be sure to use super fresh free-range eggs.
If you don't like using raw eggs in desserts you could try my easy eggless tiramisu recipe. - Rum: Use a good quality rum, one you would be happy drinking as it is one of the major flavours in this fridge cake. The biscuits are brushed with it. You could use a couple of drops of rum essence if you are avoiding alcohol.
- Milk: Full cream is preferred, but you can use the normal milk you have on hand.
- Butter: You cannot substitute margarine in this recipe, or any other fat, it needs to be butter for taste and the structural integrity of the dessert.
- Almond Essence: It enhances the almond flavour of the biscotten torte. If you don't want to buy a bottle just for this dessert, substitute with vanilla.
What to serve with biscotten torte?
The dessert is perfect as it is. How it is prepared is how we eat it. Simply decorated with shaved chocolate or chocolate flake. You could use chocolate sprinkles as well.
If you feel like taking it to the next level in presentation. Serve with a side of fresh strawberries, or other berries in season. You could also use strawberries along with the chocolate to decorate.
Recipe cost and time-saving ideas.
As far as cost is concerned this biscuit fridge cake is made with simple and basic ingredients. When you look at the list they are all basic pantry/fridge staples.
If you don't want to buy a bottle of almond essence, substitute it with vanilla. Though, the almond essence does add and enhance the flavour.
The undecorated torte can be made up to 48 hours before serving. This alone really saves you time. It can be decorated the night before, or the day of serving.

How long will this recipe take me to make?
This is pretty easy and quick to prepare. It will take approximately 20 minutes to prepare up to the "chilling in the fridge" stage.
Then you need to allow it to set for at least 8 hours. It is better at 24 hours, even more so at 48 hours.
Important step 1
- Cream butter and sugar until light and fluffy.
- Beat egg yolks into the creamed mixture.
- Add the ground almonds and almond essence. Then gradually beat in the milk.
- In a clean bowl beat egg whites until stiff peaks form.
- Fold half into the creamed mixture, then fold in the remaining egg whites.
- Arrange six biscuits lengthwise in two rows, beside each other, on aluminium foil. Brush the biscuits liberally with the rum/milk mixture.
- Spread the biscuits evenly with one-third of the filling. Top with another layer of biscuits and brush liberally with rum/milk mixture.
- Continue as before until all mixture is finished and you have ended with a layer of biscuits (again brush liberally with rum/milk).
- Wrap the torte well in two layers of foil.
- Place on a sturdy flat board or plate and place in the fridge to chill.
- When you are ready to decorate the torte remove the foil.
- Place the torte upside down on the serving platter, so that the flat side is on the top.
- Cover it completely with whipped cream and decorate with chocolate shavings.
Sara's Top Recipe Tips
Don't be put off by how much of an ugly duckling this cake looks before it is decorated. Because, let's be serious it is butt ugly.
The magic of this cake happens in the fridge. When left to chill the biscuits become softer and the flavours or meld. The longer you can leave it the better.
No, using butter is important in keeping the fridge cake together. Butter hardens in the fridge, whereas margarine is always soft. Using margarine won't hold the cake's shape.
I always use dark rum, not white rum. Dark rum has a deeper and rounder flavour than white.

Rosemary Korngold
My Dad who was Austrian and loved to cook used to make this for birthdays. However, he used sponge fingers soaked in the rum rather than biscuits and used to put weights on top overnight so that everything really soaked in. It was my very favourite dessert.
Sara McCleary
Hi Rosemary
I'm so glad you dropped by and left a comment. I love the idea of using sponge fingers and I am kicking myself that I hadn't thought of it. It is a really great idea, and I can see the appeal. I will be giving it a go.
It will make for a softer dessert, almost tiramisu style. Though the filling will have more structure when chilled due to the butter. Brilliant!!
Thank you for sharing.
Cheers, Sara

This is one of my favorite show off desserts. It looks great, it tastes sensational and it is better when made the day before. I make the dessert with Scotch finger biscuits....a shortbread biscuit. I have the recipe in one of the first recipe books I purchased when newly married 50 years ago and I guard it with great vehemence from my daughters who love the recipe and make it also.

Sara McCleary
It is a favourite of mine too. I make it for my husband for his birthday every year. I love how you use Scotch fingers, I am going to have to give that a try!
Andy
My mum made this year in year out after I pixked I t out of the Women's Weekly 'Cooking Class' cookbook for my 10th birthday (almost 30 years ago!!). Since she passed I have taken on the mantle! Just my favourite thing in the world to eat. I have just made it for Christmas and it is resting in the fridge right now. Can't wait to table it tomorrow and am going to take on the suggestion of the Flake!!! Thanks for posting the recipe and your story... feeling nostalgic on Christmas Eve. Merry Christmas!!! ๐
Sarah
Hi Sara,
I googled this dessert and was delighted to come across yours. My mum used to make this also and I plan to make it for a dinner party this weekend, but I'm still yet to claim her vintage Women's Weekly books with the recipe in it. So yours will do just perfectly I'm sure!
Lau@corridorkitchen
My mum used to make this for dinner parties too!
Sara
Hi Lucas, awe I am so so flattered ๐
Hi Rita, they are a fantastic style of dessert, and yes layers look impressive no matter how they have been made.
Rita (mademoiselle dรฉlicieuse)
I love desserts like this - they present well, can be made ahead AND are made with minimal stress-inducement! My tiramisu is much the same and, like this torte with its layers, always impresses guests with its stature despite it being a breeze to whip up.
Lucas @ CoverVersions.tv
I present a dramatic re-enactment of my seeing this post.
"Oh hey there's a bellyrumbles post in my RSS feed. Torte, huh? Well, I'm not really a cake-making person but I suppose I'll click andOH MY GOD I MUST MAKE THIS."
So suffice to say it made an impression. If it didn't take overnight, I'd be making this TONIGHT.
Katherine V
Looks great, I'm giving it a whirl tonight. Thanks ๐
Sara
Hi KatherineV, ooo good luck with it, hope it turns out, let me know how you go.
Hi Martyna, very decadent but you can't stop at one slice.
Martyna@WholesomeCook
YUM! Plain biscuits can make a fine dessert - this is decadent and I don't think I could stop at just one serving!
Sara
Hi Catty, thanks so much, is pretty easy to make, give it a go.
Hi TheFoodSage, glad you agree with the no tarting of the torte, there is something special about a recipe from your mum.
HI Sarah, yep sub the bics and it will work a treat.
Hi Lorraine, yes I have seen the choc ripple recipe around in a few places, I must give it a go, as it looks pretty in log form.
Hi Shez, that is so cool, I bet there are lots of similar recipes out there.
HI Chopinand, generally I am not a sweet girl, but this I can eat and eat.
HI Gaby, oh that is very cool.
Hi Apple, please let me know how you go if you do make it, would love to know.
Hi Anna, trust me the wait is worth every second.
Anna@ The Littlest Anchovy
This looks really simple to make and the combination of almonds, cream and rum would be amazing. I don't know how on earth anyone could wait for 18 hours before wanting to tear into ith though!
Apple
Oh it looks so wonderful! I love that you've included details on why not to use margarine. Like many people I'm sure I try to cut corners. I'm going to give this a go next time I'm entertaining for people. My mouth is watering looking at it!
Gaby
My aunties used to make a very similar biscuit cake when I was a kid, you just brought those happy memories back ๐
Chopinand @ ChopinandMysaucepan
Dear Sara,
I don't have a sweet tooth so I don't really have any fave desserts from childhood. I can handle savoury and not so sweet desserts though ๐
shez
Ohmygosh my mum has been making a really similar dessert since we were kids except we use cream cheese instead of butter. I even got her to make one for my birthday last year ๐ I love family recipes like this so much. They make the world a far better place.
Lorraine @ Not Quite Nigella
Ooh I've made the choc ripple version but this sounds even better! ๐
Sarah @ The Healthy Diva
This looks totally divine!!! I love easy yummy desserts. All i have to do is substitute for gluten free plain biscuits...awesome. Thanks sara ๐
The Food Sage
I'm so glad you didn't "tart up the torte"! It looks gorgeous just as is. I, too, have some foolproof dessert recipes handed down from my mam. I love the memories that come with them, and i'm so pleased you shared yours. Lovely to hear. Good on your mum for serving her gorgeous torte to dinner guests with a slice missing. What a lovely story. What a lovely mum!
catty
OH MY GOD. I can't take my eyes off that top photo!!!! It looks amazing, and doesn't sound tooooooooooooo hard, I may have to try this myself!
