Ingredients

• 1 box (15.25 ounces) yellow cake mix
• 1 box (3.4 ounces) instant lemon pudding mix
• 1 cup cold whole milk
• 1/3 cup neutral oil (such as canola or vegetable oil)
• 3 large eggs
• 1/2 cup granulated sugar
• 1 teaspoon pure vanilla extract
• 1 tablespoon finely grated lemon zest (from about 1 lemon)
• Nonstick cooking spray or butter, for greasing the pan
• Optional: powdered sugar or lightly sweetened whipped cream for serving

Instructions

1. Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch metal baking pan with nonstick spray or butter, making sure to coat the corners well.
2. In a large mixing bowl, whisk together the yellow cake mix and instant lemon pudding mix until evenly combined.
3. In a separate medium bowl or large measuring cup, whisk together the cold milk, oil, eggs, granulated sugar, and vanilla extract until smooth and well blended.
4. Pour the wet ingredients into the dry ingredients. Add the lemon zest and mix using a hand mixer on medium speed or a sturdy whisk for about 2 minutes, until the batter becomes thick, smooth, and glossy.
5. Scrape down the sides and bottom of the bowl to ensure there are no dry pockets remaining.
6. Transfer the batter into the prepared baking pan and spread it evenly into the corners with a spatula. Lightly swirl the top for a rustic, homemade appearance.
7. Bake on the center rack for 28–34 minutes, or until the top is lightly golden and a toothpick inserted into the center comes out with a few moist crumbs but no wet batter.
8. Remove the cake from the oven and place the pan on a wire rack. Allow the cake to cool completely in the pan so the soft, pudding-like texture can fully set.
9. Once cooled, dust lightly with powdered sugar or top with whipped cream if desired. Slice into squares and serve directly from the pan.
10. Store leftovers covered in the refrigerator for up to 4 days.
