Preheat the oven to 350°F (175°C). Grease a 9x13-inch baking pan, making sure to coat the corners well.

In a large bowl, beat the eggs. Add the cake mix, lemon pudding mix, oil, water, and lemon zest. Mix until smooth and evenly combined, scraping the bottom of the bowl once.

Pour the batter into the prepared pan and spread it level. Bake for 30-35 minutes, until the top springs back and a toothpick inserted in the center comes out with moist crumbs.

While the cake bakes, whisk powdered sugar, lemon juice, melted butter, and water until smooth and pourable. Add a little more water only if the glaze is too thick to pour.
05 -
Let the cake cool for 10 minutes. Use a skewer or the handle of a wooden spoon to poke holes evenly over the surface.

Pour the glaze slowly over the warm cake, guiding it toward the edges. Let the cake cool completely so the glaze can set before slicing into 12 squares.
