It’s a nostalgic taste of sunshine and Nana’s love.

Recipe Overview

Prep Time: 15 minutes
Cook Time: 18-20 minutes
Total Time: 33-35 minutes
Servings: 36
Dietary Type: Not specified (contains dairy and eggs)

Ingredients

18 ½ ounces lemon cake mix
4 eggs
3 ½ ounces instant lemon pudding
2 cups milk
3 ounces cream cheese (softened)
½ cup butter (softened) or ½ cup margarine (softened)
2 cups powdered sugar
1 ½ teaspoons vanilla extract

Equipment Needed

15x10x1-inch baking pan
Mixing bowls
Electric mixer
Rubber spatula
Toothpick

Instructions

Begin by preheating your oven to 350°F (175°C). Ensuring the oven is fully preheated will help the cake bake evenly.
Prepare your baking pan by spraying it generously with non-stick cooking spray. Make sure to get into all the corners and sides to prevent the cake from sticking. Set the prepared pan aside.
In a medium mixing bowl, combine the instant lemon pudding and 2 cups of milk. Whisk together until the pudding starts to set. This will take a few minutes. Set this mixture aside as it thickens; this pudding adds moisture and that signature lemon flavor to the cake.
In a large mixing bowl, combine the lemon cake mix and 4 eggs. Use an electric mixer to combine these ingredients. Mix until just combined; be careful not to overmix at this stage. Overmixing can lead to a tough cake.
Now, gently fold the lemon pudding mixture into the cake mix batter. Use a rubber spatula to fold it in until just combined. Be gentle to avoid deflating the batter. This step is key to ensuring a moist and tender cake.
Pour the batter into the prepared 15x10x1-inch baking pan and spread it evenly.
Bake in the preheated oven for 18-20 minutes, or until a toothpick inserted into the center comes out clean. The baking time can vary depending on your oven, so start checking for doneness around 18 minutes. If the top starts to brown too quickly, you can loosely tent it with foil.
While the cake is cooling in the pan, prepare the frosting. In a separate mixing bowl, combine the softened cream cheese and softened butter (or margarine). Beat with an electric mixer until smooth and creamy.
Gradually add the powdered sugar to the cream cheese and butter mixture, beating on low speed until incorporated. Then, add the vanilla extract and beat until smooth and fluffy. Adjust the amount of powdered sugar to reach your desired consistency, adding more for a thicker frosting.
Once the cake has cooled completely, frost it generously with the cream cheese frosting. Spread the frosting evenly over the top of the cake.
Cut into squares and serve!

Expert Tips & Tricks

Moist Cake Secret: For an extra moist cake, cover the pan with foil immediately after removing it from the oven. This traps the steam and keeps the cake incredibly tender. Let it cool completely under the foil.
Pan Prep for Potlucks: When bringing this cake to a potluck, line the pan with aluminum foil, leaving an overhang on the sides. Spray the foil with non-stick cooking spray. Once the cake is cooled and frosted, you can easily lift it out of the pan using the foil overhang. This makes it easy to slice and serve.
Perfect Softened Butter/Cream Cheese: Make sure the cream cheese and butter are truly softened for the frosting. Take them out of the fridge about an hour before you plan to bake. This will prevent lumps in your frosting.
Cake Mix Magic: Using a cake mix makes this recipe incredibly easy, but you can elevate the flavor by adding a teaspoon of lemon zest to the batter.

Serving & Storage Suggestions

This lemon sheet cake is delicious served chilled or at room temperature. Cut it into squares and serve as a dessert or snack. For a beautiful presentation, you can dust the top with a little extra powdered sugar or garnish with fresh berries.

Room Temperature: The frosted cake can be stored at room temperature for up to 2 days in an airtight container.
Refrigeration: For longer storage, keep the cake in the refrigerator in an airtight container for up to 5 days.
Freezing: You can also freeze the cake for up to 2 months. Wrap it tightly in plastic wrap and then in foil. Thaw overnight in the refrigerator before serving.
Freezing for Summer Treats: As mentioned, this cake freezes exceptionally well. Freezing individual squares is a great way to have a sweet treat on hand for race days or hot summer days. It thaws quickly and makes for a refreshing snack.

FAQs (Frequently Asked Questions)

Q: Can I use a different size pan?

A: While the recipe is designed for a 15x10x1-inch pan, you can use smaller pans. Be aware that the cake will be thicker and may require a longer baking time. Keep a close eye on it and test for doneness with a toothpick.

Q: What if I don’t have instant lemon pudding?

A: The instant lemon pudding adds moisture and flavor, but you can try substituting it with an equal amount of sour cream or plain yogurt. However, the texture and flavor will be slightly different.

Q: My frosting is too thin. What can I do?

A: If your frosting is too thin, gradually add more powdered sugar, one tablespoon at a time, until you reach your desired consistency.

Q: Can I add lemon zest to the cake batter?

A: Absolutely! Adding 1-2 teaspoons of lemon zest to the batter will enhance the lemon flavor and add a lovely aroma.

Q: How do I prevent the cake from sticking to the pan?
