How to make a white chocolate key lime tart

White Chocolate Key Lime Fruit Tart not only is pretty to look at it tastes amazing! Melted white chocolate is mixed with sour cream and cream cheese as a filling for this tart. However, key lime curd is spread over the buttery home made pie shell. It’s almost no bake except for baking the crust 15-20 minutes. Fresh strawberries, blueberries, raspberries and kiwi sliced and arranged on top of the tart is lovely.

Summer fruit tarts are typically easy to make. This recipe is one of those tarts. You can use refrigerated pie crust if you would like, but I enjoy making home made food processor butter pie crust. You will want to make this tart for your family and every time you have guests.

If you plan to use Microwave Key Lime Curd make this earlier in the day as it needs time to set up in the refrigerator. About 2-4 hours will be perfect.

Tart Shell Crust Begin making the tart crust. In a food processor fitted with steel blade add flour, sugar, salt and chilled cubed butter, pulse a few seconds to toss and cut up butter. Next, add 3 tablespoons of ICE COLD water. It has to be ice cold or you will have a sticky dough, which means you would add more flour and end up with a tough dough. Not a happy time.

Once you pulse all the ingredients for the crust, it will form a ball around the blade. This is the sign your dough is ready. Remove from food processor, flatten into a disc and cover with plastic wrap then to the refrigerator for a big chill, about 20 minutes.

Meanwhile, preheat oven to 375 degrees. Lightly spray with cooking spray a 9-inch springform tart pan. Next, cut a 9-inch parchment round and gather your pie weights. We are baking a single tart shell and not the filling.

Tip: Pie Weights can be dried beans, black eyed peas or rice. Placing the parchment paper in the tart pan with weights will assist the shell from rising during the bake. Parchment also helps keep the beans from imprinting your dough.

Roll out dough on floured surface with rolling pin into a 10-inch circle. Line 9″tart springform pan with dough, press up the sides and bottom of the pan. Line with parchment round and beans. Bake at 375 degrees for 15-20 minutes. Cool crust completely before filling.

Making the White Chocolate Key Lime Filling

If you haven’t made the Microwave Key Lime Curd yet, do it now. The curd needs at least 2 hours to firm up, chilling will help this process. Store curd in refrigerator up to 10 days. This curd will line the baked tart shell before adding the white chocolate filling.

This is a no bake filling and so delicious. Instead of using white chocolate instant pudding and pie mix you can make your own. I decided to melt Baker’s White Chocolate Baking bars in 1/4 cup heavy cream. In a microwave safe bowl, add finely chopped white chocolate and cream. Microwave for 1 minute, stir until melted. You can continue to microwave chocolate at 30 second intervals if it isn’t melting. Add 1/4 cup key lime curd to melted chocolate.

Melting white chocolate

Tip: White Chocolate is a touchy chocolate to melt. Some brands melt like a dream while others will not melt. Bakers white chocolate is made for baking and has cocoa butter. White chocolate chips for the most part except Ghirardelli will not melt for they are designed for chips as in cookies or bars. Just check your white chocolate and percentage of cocoa butter, the more you have the better it will melt.

In separate mixing bowl, whip softened cream cheese, confectioners sugar and sour cream until thick and creamy. Once it is smooth, add white chocolate mix to cream cheese. Beat on high speed to combine. Chill until ready to assemble tart. When ready to assemble, spread over the key lime curd in baked tart shell. Using an off set spatula will help with spreading.

  1. I love this tart! The shortbread crust is semi sweet, bakes like a dream and holds the filling beautifully. I used Bakers White Chocolate baking bar and the microwave lemon curd in the filling. So delicious with the fresh berries glazed in apricot jam.
