  • 1 box (18.25 oz.) lemon cake mix
  • 4 large eggs, divided
  • 3⁄4 cup melted butter, divided
  • 3⁄4 cup buttermilk
  • 1⁄3 cup lemon juice
  • 1⁄3 cup granulated sugar
  • 1 Tbsp. grated lemon zest
  • 1⁄2 cup confectioners’ sugar


  • Preheat oven to 350°F.
  • Line a 9-by-13-inch Pyrex pan with aluminum foil. Leave enough foil sticking up from the pan to allow you to use it to lift out the baked bars. Grease the foil.
  • Set aside 1 cup cake mix; reserve for later use.
  • In a large mixing bowl, beat the remaining cake mix, 1 egg, and 1⁄4 cup melted butter with an electric mixer on low speed to form a smooth batter.
  • Pat this mixture into the bottom of the pan.
  • In a separate bowl, mix remaining 3 eggs, remaining 1⁄2 cup melted butter, buttermilk, lemon juice, granulated sugar, and lemon zest. Beat for 2 minutes with an electric mixer on medium speed.
  • Add lemon mixture over batter layer in pan. Bake for 35 minutes or until set and golden.
  • Use oven mitts to lift cookies out of pan by the aluminum foil edges. Remove to wire rack to cool completely. Sprinkle with confectioners’ sugar.
