Ingredients

1/2 cup coconut oil, melted, plus more for brushing 

1/4 cup cane sugar 

1 teaspoon pure vanilla extract 

1/4 teaspoon coarse salt 

1 1/2 cups whole-wheat pastry flour 

1/2 cup silken tofu 

3/4 cup cane sugar 

1 tablespoon grated lemon zest 

1/4 cup lemon juice 

1/4 teaspoon baking powder 

2 tablespoons whole-wheat pastry flour 

Confectioners' sugar, for dusting 

Preparation

Heat oven to 350 degrees. Brush an 8-inch-square baking dish with oil, then line with parchment, leaving an overhang, and brush parchment with oil. Set aside.

Make the crust: Stir together 1/2 cup oil, sugar, vanilla, and salt. Add flour and stir until just combined. Press dough into prepared dish and bake until pale golden-brown, about 20 minutes.

Meanwhile, make the filling: Process tofu, sugar, lemon zest and juice, baking powder, and flour in a food processor until smooth. Pour onto baked crust and bake until set, 25 to 30 minutes more. Let cool completely, then dust with confectioners’ sugar and cut into squares.
