1 stick (4 ounces) unsalted butter, at room temperature
2 cups sugar
1 cup plain whole-milk yogurt
3 large eggs, lightly beaten
1 tablespoon finely grated lemon zest
1 tablespoon fresh lemon juice
1/2 teaspoon pure vanilla extract Confectioners’ sugar, for dusting
Preheat the oven to 350°. Butter and flour a 9-inch-square cake pan. In a bowl, whisk the flour with the baking soda and salt. In a bowl, beat the butter with the sugar until smooth. Beat in the yogurt, followed by the eggs, lemon zest, lemon juice and vanilla. Gradually beat in the dry ingredients until blended.
Scrape the batter into the prepared pan and bake for about 45 minutes, or until golden brown and a cake tester inserted in the center of the cake comes out clean. Transfer the cake to a rack to cool for 10 minutes, then invert the cake onto the rack and let cool completely. Dust with confectioners’ sugar before serving.
1 Tbs. cornstarch dissolved in 2 Tbs. soy milk or rice milk.
Crust: Preheat oven to 350 degrees. In medium bowl, mix cracker crumbs, syrup and extract until crumbs are moistened. Pour into oiled 9-inch pie plate; press mixture firmly to form crust. Bake 5 minutes; let cool while preparing the filling.
In food processor or blender, combine remaining ingredients and process until smooth, about 30 seconds. Pour mixture into crust. Bake until top is slightly browned, about 30 minutes. Cool and refrigerate until thoroughly chilled and firm, about 2 hours.
