Step 1

With the rack in the middle position, preheat the oven to 350°F (180°C). Butter and line a square 8-inch (20 cm) cake pan with parchment paper, letting it hang over two sides.

Step 2

In a bowl, combine all the ingredients until the dough has a grainy texture. Lightly press into the prepared pan. Bake for 15 minutes and let cool.

Step 3

Meanwhile, in another bowl, combine the sugar and cornstarch. Whisk in the eggs. Stir in the mango purée and lemon juice. Pour onto the crust.

Step 4

Bake for 20 minutes or until the filling is set. Let cool on a wire rack. Cover with plastic wrap directly on the surface of the filling and refrigerate for 2 hours. Unmould and cut into squares.
