Ingredients

• 1 1/4 cups all-purpose flour
• 1/4 cup unsweetened cocoa powder
• 1/2 cup cold unsalted butter
• 2 tbsp granulated sugar
• 2 tbsp lemon zest
• 2 large eggs
• 1/2 cup fresh lemon juice
• 1/2 cup granulated sugar
• 2 tbsp cornstarch
• 3 oz semisweet chocolate
• 1/4 cup powdered sugar

Instructions

1. Step 1: For crust: In a food processor, pulse 1 1/4 cups all-purpose flour, 1/4 cup unsweetened cocoa powder, 1/2 cup cold unsalted butter (cut into 1/2-inch cubes), 2 tbsp granulated sugar, and 2 tbsp lemon zest until the mixture resembles coarse sand. Press firmly into the bottom and up the sides of a 9-inch tart pan. Chill for 30 minutes.
2. Step 2: Preheat oven to 350°F (175°C). Bake the chilled crust for 15-18 minutes until golden around the edges. Let cool completely on a wire rack.
3. Step 3: For filling: Whisk 2 large eggs, 1/2 cup fresh lemon juice, 1/2 cup granulated sugar, and 2 tbsp cornstarch in a medium saucepan until smooth. Cook over medium heat, stirring constantly, until the mixture thickens and coats the back of a spoon (about 10 minutes). Remove from heat and stir in 2 tbsp lemon zest.
4. Step 4: Pour the warm filling into the cooled crust, spreading evenly. Bake at 350°F (175°C) for 15-18 minutes until the center is just set but still slightly jiggly. Cool completely at room temperature (at least 2 hours).
5. Step 5: Melt 3 oz semisweet chocolate in a double boiler or microwave, stirring every 20 seconds until smooth. Drizzle over the cooled tart in a zigzag pattern. Sprinkle with 1/4 cup powdered sugar and let set for 15 minutes before slicing.
