This easy blueberry tart features sweet juicy blueberries baked over a layer of egg-free frangipane (almond cream) in a no-fuss, flakey puff pastry crust for an easy vegan dessert.
Combine all of the ingredients for the almond cream in a blender or food processor. Blend until a smooth mixture forms, scraping down the sides as needed. Set aside.
On a lightly floured surface, roll out the puff pastry to a rough rectangle about ¼” (½ cm) thick. Place the pastry on a parchment lined baking sheet.
Place the blueberries in a medium sized bowl. Add in the sugar, cornstarch, lemon juice and vanilla. Stir well to evenly coat the berries.
Spread the almond cream over the pastry with a spoon or offset spatula, leaving a 1-2" (2.5-5 cm) border of pastry uncovered.
Carefully spoon the blueberries over the almond cream. Fold edges of the pastry up and over the edge of the blueberry filling.
Lightly brush the milk onto the crust, and sprinkle with the sliced almonds and coarse sugar. (The milk helps the almonds stick, and the pastry to brown.)
Bake in the preheated oven for 40-45 minutes, or until the center is bubbling gently and the crust is golden brown. Let cool for about 10 minutes before slicing. The filling will set as it cools further, allowing for tidier slices.
Serve on its own, or with a dollop of whipped dairy-free cream or a scoop of ice cream.
Store in an airtight container (or wrap in cling wrap or foil) in the refrigerator for up to 5 days. The pastry will soften. To recrisp the pastry, preheat the oven to 350°F/177°C/gas mark 4. Heat the tart in the oven for about 15 minutes.
If you don't have ground almonds, you can grind up your own blanched sliced or slivered almonds. Run them in the food processor or blender for a minute or so, scraping down the sides as needed, until they are ground up.
Custard Powder
Bird's custard powder is an eggless custard power. It is mostly cornstarch with flavoring and a touch of pigment for a more typical light yellow custard color. It can be found in most large grocery stores and online. If you don't have any, you can use an equal amount of cornstarch.
Puff Pastry
If you don't have puff pastry, you can use regular pie pastry, either store-bought or homemade. Follow the pastry and assembly instructions for this galette.
