These easy tiramisu brownies combine a deep, fudgy 70% dark chocolate brownie base with coffee-soaked sponge fingers and a thick whipped mascarpone topping. Taking 45 minutes to prep and 25–30 minutes to bake, they set overnight in the fridge into 16 sliceable, decadent squares. Perfect for dinner parties, weekend treats, or coffee lovers looking for an elevated traybake.

Tiramisu Bakes

I have made it clear in the past how much I love anything tiramisu themed. Between tiramisu and sticky toffee pudding, I can never decide which I adore more. There is something about the cosy-ness of a sticky toffee, but the lightness and fresh flavours of a tiramisu is just glorious. 

My basic tiramisu recipe is in my third book Everyday, and I make it so regularly. On my blog, I’ve had fun with different tiramisu inspired bakes such as with my favourite ever cheesecake (my tiramisu cheesecake), and also my lemon tiramisu and my tiramisu tart recipes. The combination of flavours in every bake is just THE BEST. Brownies though? That’s a whole level up.

Brownie Batter

For this recipe, I wanted to not over-do it on the brownie base, so I went for a simple six ingredient base. The chocolate, butter, eggs, sugar, flour and cocoa make a thick and fudgy base that are perfect for these tiramisu brownies. I bake into a 9″ square tin so the depth of the brownies is perfect… any larger or smaller, this can cause a problem with the bake. 

  • Chocolate – I’ll always say this: dark chocolate is essential for truly great brownies. Aim for chocolate with at least 70% cocoa solids to achieve a deep, rich flavour.
  • Butter – Unsalted block butter works perfectly, but a good-quality baking spread is just as effective. Brownies in this sense are forgiving, so use whichever you have available.
  • Eggs – I usually bake with medium eggs, though large eggs work well too. For the ideal brownie texture, use either 4 medium eggs or 3 large ones.
  • Sugar – I alternate between light brown soft sugar and caster sugar depending on the flavour I want or what’s in the cupboard. For this recipe, I chose light brown soft sugar to bring a subtle caramel note.
  • Flour – Plain flour is all you need for brownies. There’s no need for any raising agents.
  • Cocoa Powder – I like to use a bold, high-quality cocoa powder to really intensify the chocolate flavour. The richer it is, the better the result.

Sponge fingers?!

I would say that sponge fingers (or ladyfingers) are an essential part of any tiramisu themed bake, and I will not take any other word about it. You can find sponge fingers in basically all supermarkets, and they’re relatively cheap. I used shop bought sponge fingers for ease, but if you want to make your own, go for it! 

Just like in a tiramisu bake, I wanted to soak the sponge fingers in a coffee mixture to partly have the texture element, but also more importantly, the flavour element. I used a mix of a STRONG coffee liquid, with some coffee liqueur mixed in for a bit of a kick. You can of course leave out the alcohol, and just use the strong coffee instead. I used espresso from my coffee machine, but you can use instant coffee and dissolve it as well. 

When the brownies are fresh out of the oven, I dunk my sponge fingers in the coffee liquid for a few seconds (it’s best if it’s cooled down so you don’t sizzle your fingers) and then lay on top of the brownie. I really sandwich them in on top so it fills a layer of the tin I have used and entirely covers the brownie

Tiramisu Topping

When I make an actual tiramisu, I don’t tend to use cream. I want to use the egg yolk/white method with mascarpone, because it makes a particularly delicious topping and is more authentic from what I have been told. It works ideally for the tiramisu dessert, but because this recipe is for brownies and needs to ideally be more stable and slightly denser on purpose, I switched it up. 

The topping, which goes on top of the soaked sponge fingers, is a mix of full-fat mascarpone, double cream, icing sugar and vanilla extract whipped together. I also used the addition of come coffee liqueur, but this is optional. When making this part of the recipe you need to use full-fat ingredients to make sure it sets. 

I whip all of the ingredients together to medium-stiff peaks, making sure to not over whisk it. It needs to be lovely and thick so it stays put once you portion the brownies, so it does need to whisk up as much as possible. Whisk little and often to check the texture, and make it lovely and thick 

I then set the tiramisu brownies over night, to allow the topping time to set, as well as the brownies to set into a really fudgy texture as well. Once out the fridge the next day, dust liberally with cocoa powder, slice and serve.

FAQs

Can I make these tiramisu brownies without alcohol?

Yes. Simply omit the coffee liqueur entirely. Replace the 50ml of liqueur in the sponge soaking liquid with an additional 50ml of strong black coffee, and leave it out of the mascarpone topping without needing any liquid replacement.

Why is my mascarpone topping runny instead of thick?

Runny topping is caused by using low-fat cream or mascarpone, or by under-whisking. If the mixture is under-whisked, continue beating gently until stiff peaks form. If it has split from over-whisking, gently fold in a tablespoon of cold unwhipped double cream to bring the emulsion back together.

Can I add chocolate chips to the brownie batter?

Absolutey. Folding 100g to 200g of dark or milk chocolate chips into the batter before baking adds extra pockets of chocolate throughout the fudgey base.

How do I know when the brownie base is done baking?

Check the bake at 25 minutes. The edges should be set and slightly pulled away from the parchment paper, while the centre should retain a slight wobble when the tin is gently shaken.

Topping

  • 250 g full-fat mascarpone
  • 250 ml double cream
  • 3 tbsp icing sugar
  • 1 tsp vanilla extract
  • 50 ml coffee liqueur

Instructions

Brownie

  • Preheat the oven to 180ºc/160ºc fan and line a 9×9" square tin with parchment paper and leave to the side for now.
  • Add the dark chocolate and butter to a bowl, and melt the two together until smooth. I do this in the microwave. Leave to cool for 5-10 minutes
  • In a new bowl, add the sugar and eggs and whisk together for a couple of minutes until doubled in volume, and mousse like
  • Fold through the cooled butter/chocolate mixture and then fold through the plain flour and cocoa powder
  • Pour the mixture into the lined tin and then bake in the oven for 25-30 minutes until there is a slight wobble in the middle. Remove from the oven.

Filling

  • Mix together the strong black coffee and coffee liqueur
  • Dunk each sponge finger into the coffee mixture for a few seconds and add on top of the brownie
  • Completely cover the top of the brownie in soaked sponge fingers

Topping

  • Add the mascarpone, cream, sugar, vanilla and coffee liqueur to a bowl
  • Whisk together to combine and then thicken the mixture. It needs to be thick and spreadable ideally, just make sure to not over whisk so check often.
  • Carefully spread evenly over the top of the sponge fingers.
  • Set the brownies in the fridge overnight.
  • Once set, dust the top with cocoa powder, and slice up and enjoy.

Notes

  • I use a 9″ square tin for this recipe
  • These last for 3-4+ days in the fridge
  • You can freeze these for 3+ months 
  • I’d recommend using dark chocolate of 70% cocoa content for the best bake 
  • Make sure to use full-fat ingredients in the topping especially to make sure it sets 
  • The alcohol is optional, you can leave it out of the topping mix, and increase the coffee mix for the sponge fingers
  • You can add chocolate chips to the brownie mixture if you want – 100-200g worth would be tasty

Storage and freezing

Because the topping contains fresh dairy and mascarpone, these tiramisu brownies must be stored in an airtight container in the fridge, where they will stay fresh and fudgey for 3 to 4 days. For long-term storage, the un-topped baked brownie base can be frozen for up to 3 months when wrapped tightly in clingfilm.

    Just wondering if it would be possible to add raspberries into the brownie mixture, if so what measurements would you recommend.❤️

    Would it be possible to add Baileys to the topping and if so, what measurement would you recommend? Can’t wait to give these a go.

    I made these with gluten-free flour and gluten-free sponge fingers. And added the coffee mix to the topping in intervals to get the perfect coffee taste for us.
    😋😋😋😋, they are lipsmackingly delish!!!

    Hi Jane
    do i cool the brownies before adding the topping?

    • Jane's Patisserie on January 23, 2026 at 2:36 pm

      I put the sponge finger layer on straight away, and then the mascarpone topping on that – by the time I’d finished the layers, the brownie was cool enough to put into the fridge x
