Get ready to fall in love with your new favorite summer dessert! This show-stopping Blueberry Custard Tart is the perfect centerpiece for picnics, brunches, or any sunny-day celebration. We’re starting with an ingenious, buttery mozzarella pastry that bakes up crisp and golden, providing the perfect vessel for what’s inside. The filling is a dream—a velvety, rich egg custard so smooth and creamy it rivals the texture of a classic crème brûlée. Studded with juicy blueberries and crowned with a cloud of whipped cream, every bite is a perfect balance of sweet, tart, and decadent.
Ingredients
• For the Crust
• 1 recipe Mozzarella Pastry Dough (see recipe here)
• For the Blueberry Custard Filling
• 5 large egg yolks
• 2 large eggs
• 1 ½ cups / 360 ml heavy cream
• 1 cup / 150 g fresh blueberries
• ½ cup / 120 ml whole milk
• ½ cup / 95 g granulated low-carb sweetener of your choice
• For the Topping
• 1 cup / 240 ml heavy cream
• 1 cup / 150 g fresh blueberries
Instructions
1. Preheat your oven to 300°F / 150°C.
2. Prepare the Mozzarella Pastry Dough according to the recipe . Gently press the dough into a 9-inch / 23-cm round pie dish, line it with parchment paper, and par-bake for 15 minutes to create a crisp base.
3. While the crust bakes, create the luscious filling. Place the egg yolks, whole eggs, heavy cream, milk, blueberries, and sweetener into a blender. Blend on high for 2 to 3 minutes until the mixture is completely smooth and airy.
4. Carefully pour the blended custard into the warm, par-baked crust. Return the tart to the oven and bake for 30 to 40 minutes. The custard is ready when the edges are set, but the center still has a gentle wobble.
5. Patience is key! Allow the tart to cool completely, then chill in the refrigerator for at least 3 hours, or preferably overnight, to allow the custard to fully set.
6. Just before serving, whip the cream for the topping until stiff peaks form. Spread it lovingly over the chilled tart and finish with a generous scattering of fresh blueberries. Serve cold and store any leftovers in the refrigerator for up to 3 days.

Pro Tips
• For the smoothest custard, ensure your eggs, cream, and milk are at room temperature before blending. This helps them emulsify beautifully.
• The ‘wobble’ is your best friend! Overbaking will lead to a rubbery, cracked custard. Pull the tart from the oven when the center jiggles like set Jell-O.
• Chilling isn’t optional—it’s essential for the custard to set properly. An overnight chill yields the best texture and makes for cleaner slices.
• For a picture-perfect slice, dip a sharp knife in hot water and wipe it clean between each cut.
