Ingredients
– 2 ¼ cups (292g) all-purpose flour, spooned and leveled
– 1 tablespoon cornstarch (optional, for tenderness)
– 1 teaspoon baking powder (or ½ teaspoon baking soda as an alternative)
– ¼ to ½ teaspoon salt
– ¾ cup (180g) unsalted butter, melted and cooled or softened
– 1 to 1 ¼ cups (200-250g) granulated sugar
– 1 large egg, room temperature
– 1 teaspoon pure vanilla extract
– 2 tablespoons lemon zest (about 2 lemons)
– ¼ to 3 tablespoons fresh lemon juice (about 1 lemon)
– Optional: 3.4 ounces dry instant lemon pudding mix (for added softness and lemon flavor)
– Optional: ¾ cup white chocolate chips
– ¼ to ½ cup (60-115g) unsalted butter, softened
– 2 to 4 ounces (60-115g) full-fat cream cheese, softened
– 1 ½ to 2 cups (195-260g) powdered sugar
– ¼ to ½ teaspoon salt
– ½ to 1 teaspoon pure vanilla extract
– ¼ to ½ teaspoon lemon zest (optional)
– Optional: 1 tablespoon fresh lemon juice to brighten flavor

Instructions
1-Preheat your oven to 350°F (175°C). Lightly grease and line a 9-inch springform or round cake pan with parchment paper.
2-In a medium bowl, whisk together the flour, cornstarch (if using), baking powder or baking soda, and salt.
3-In a large mixing bowl, combine softened or melted butter, granulated sugar, and lemon zest. Beat until well mixed and slightly fluffy if using softened butter.
4-Add the egg and vanilla extract, then stir in lemon juice. Note that the dough may appear slightly curdled if pudding mix is added.
5-Gradually fold dry ingredients into the wet mixture until just incorporated; avoid over-mixing to prevent toughness.
6-Fold in white chocolate chips if using.
7-Spread or press the dough evenly into the prepared pan. If the dough is sticky, press a sheet of parchment lightly on top to smooth.
8-Bake for 19-35 minutes depending on pan size, until the edges are golden and the center is set but still slightly soft (longer time applies to thicker cakes).
9-Allow the cookie cake to cool completely in the pan before removing and frosting.
10-Optionally, dust with powdered sugar or top with a lemon glaze before serving.
