This raspberry white chocolate tart is one of my favourite things to make. 

Dark and white chocolate combined with mascarpone cheese provide the perfect backdrop to gorgeous raspberries.

It’s quick and easy to make, too. No baking, just mixing and chilling. 

The hardest part? Waiting. Let’s get to it.

Why you’ll love making this white chocolate tart recipe

I make this tart most often when raspberries are in season and in great abundance but since they’re usually available year-round these days, this makes for an awesome dessert any time of the year.

And you’ll love making this recipe because:

  • It’s a no-bake tart. You don’t have to turn on your oven for this one. Simply combine your ingredients, allow the tart to set in the fridge, and serve.
  • You can customize easily. No raspberries? No problem. You can substitute with strawberries, blueberries and even sugared cranberries. Not in the mood for a white chocolate fruit tart? Make a dark chocolate ganache and top the tart with that. The possibilities are endless.
  • It looks stunning. Whatever topping you end up using, your tart will look very impressive. Nobody will ever suspect it took all of 2 seconds to prepare! Serve it to company, surprise loved ones on their birthday, add it to your baby shower or bridal shower menu.

How to make white chocolate raspberry tart

This tart is bursting with white chocolate flavour. But dark chocolate fans, don’t despair. The crust balances out the sweetness of the white chocolate. I love drizzling dark chocolate over the tart too. 

Ingredients

To make it, you’ll need:

  • Oreo cookie crumbs — I use pre-crushed crumbs but you can also buy the cookies and crush them yourself or pulse them in the food processor
  • Unsalted butter
  • Salt
  • Heavy cream — heavy cream has at least 36% milk fat content. In a pinch, you can use whipping cream with 30-35% milk fat content but know that your tart will not set as firmly
  • Mascarpone cheese — buy full fat mascarpone as much as possible
  • Granulated sugar
  • White chocolate — use baking white chocolate and not white chocolate chips

Tools

I use my stand mixer to make the filling but a handheld electric mixer would work well too. 

In addition, you’ll need a 9-inch tart pan with removable bottom. 

This tart will stick so a removable bottom is important. If you don’t have one, you can use a small pie dish and just make a white chocolate pie!

Tart recipe

First thing you’ll want to do is work on your crust.

Combine all ingredients until evenly moist. Transfer to your tart pan and press firmly onto the bottom and up the sides. Chill while you prepare your filling

Beat heavy cream, mascarpone cheese and sugar until you get medium-stiff peaks. Add melted white chocolate and fold.

Transfer the filling to your tart pan and spread evenly. Top with fresh raspberries and chill for at least 6 hours, preferably overnight. That’s it!

Expert tips

How to melt white chocolate

My favourite way to melt white chocolate is by microwave. 

  • Place chopped white chocolate (chopped roughly the same size) in a microwave-safe bowl
  • Microwave for 30 seconds
  • Stir
  • Repeat until the chocolate is completely melted, smooth and creamy

How to make mini tarts or tartlets

You can use this same recipe to make mini tarts or tartlets. You simply need to use mini tart pans, or you can set them up in cupcake liners in a cupcake pan.

It depends on how big (or small) you make them but the batter should be good enough for at least 12 tarts the size of regular-sized cupcakes. 

Best way to wash raspberries

I find fresh raspberries tricky to wash because they’re very delicate and fragile and when I place them under running water they tend to fall apart.

Instead, I mix 1 part white vinegar with 3 parts water in a bowl, place the raspberries there, and gently swirl them around for a couple of minutes.

Then I drain and repeat with just water.

I then lay them flat on a paper towel to dry. It’s important to use washed but dry raspberries in this recipe because soggy fruit will just make a mess of things!

Frequently asked questions

Can I use cream cheese instead of mascarpone cheese?


Compared to cream cheese, mascarpone tastes richer, is creamier and has a higher milk fat content. But if you have trouble finding mascarpone, cream cheese will work in a pinch. Just expect a slightly tangy taste that cream cheese is known for.

Can I use frozen raspberries?


I don’t recommend using frozen raspberries or other frozen fruit in this recipe because they will release too much liquid and become soggy as they thaw. What you can do is leave your white chocolate tart without toppings and serve frozen fruit on the side.

Can I use graham crackers for the crust?


You can use any kind of cookie crumbs you like! I do find that using dark chocolate for the crust complements the white chocolate mascarpone filling so well.

How long will white chocolate mascarpone tart last?


Kept in the fridge, this tart is best eaten the next day, and good up to 3 days. Remember, too, that your tart is only as good as long as your berries remain fresh.

Notes

  1. I use pre-crushed Oreo cookie crumbs but you can certainly buy the cookies and crush them yourself.
  2. Make sure your melted white chocolate has come down to room temperature before adding to your mascarpone mixture. If it’s too warm, the chocolate will seize.
  3. Also, make sure your raspberries have been washed and properly dried before placing on top of your tart.
  4. See post for more tips and FAQs.

Made this for Valentine and it was fabulous. We ate half at the get go! The filling didn't set as firmly as we'd hoped though. Any ideas?

Hi Ilona, glad you liked it! To make sure the filling sets properly, I make sure my cream mascarpone mixture is whipped stiff and I allow the tart enough time to chill.
