If you love quick sheet cake recipes, this Easy Lemon Sheet Cake is one to save. Made with a boxed cake mix and canned lemon pie filling, it requires minimal prep while still tasting homemade. It is a reliable make-ahead dessert that stores well in the refrigerator and serves a crowd with ease.
Sometimes you just need an easy recipe: the kind that comes together without much thought, uses simple ingredients, and still feels like something special when you set it on the table. That is exactly what you get with this Easy Lemon Sheet Cake. It is bright, moist, and full of fresh lemon flavor, with very little hands-on time.
I have always loved a good sheet cake. They bake quickly, slice easily, and are perfect for serving a crowd without any fuss. We have made a few here on Inspired by Charm over the years, and I have been wanting to add a lemon version to the collection. With spring right around the corner, it felt like the perfect time.
What I love most about this cake is the balance. The lemon keeps it light and bright, while the cream cheese frosting gives it just enough richness to feel like a treat. You could call it semi-homemade since it starts with a box mix and canned pie filling, but do not let that fool you; the end result tastes completely homemade, and no one will ever guess how simple it was to make. Let’s put it together.
Oh, and I have a post dedicated to all of my best lemon recipes if you’re interested in more.

Ingredients
Before we begin, let’s review the list of ingredients you’ll need for this easy sheet cake. I’ll walk you through what I used below.
- Lemon Cake Mix – This is the base of the cake, keeping the recipe simple while still delivering a soft texture and bright lemon flavor.
- Eggs – Eggs help bind everything together and give the cake structure and richness.
- Lemon Pie Filling – This adds extra moisture and a bold, sweet-tart lemon flavor, making the cake taste anything but basic.
- Cream Cheese – Softened cream cheese creates a smooth, tangy frosting that balances the sweetness of the cake beautifully.
- Butter – Butter adds richness and helps create a creamy, spreadable frosting with great flavor.
- Confectioners’ Sugar – This sweetens the frosting and gives it that classic smooth texture.
- Vanilla Extract – Just a touch rounds out the frosting and enhances the overall flavor.
- Milk – Added a little at a time, milk helps loosen the frosting to the perfect spreadable consistency.
- Salt – A small pinch sharpens the flavors and keeps the frosting from tasting overly sweet.
- Fresh Lemon Slices – Optional for garnish, these add a fresh pop of color and make the cake feel even more special when serving.

- Preheat your oven to 350 degrees F. Lightly grease a 13 x 18 x 1-inch baking pan. Set aside.
- In a large mixing bowl, combine the cake mix and eggs. Beat with an electric mixer until smooth and fully blended. Add the lemon pie filling and gently mix just until incorporated.
- Spread the batter evenly into the prepared pan, smoothing the top with a spatula. Bake for about 15 to 18 minutes, or until the center springs back lightly when touched and a toothpick inserted in the middle comes out clean. Let the cake cool completely in the pan on a wire rack.
- For the frosting, place the softened cream cheese and butter in a bowl and beat until creamy and smooth. Gradually add the confectioners’ sugar, mixing until fully combined. Stir in the vanilla extract and a pinch of salt. Add milk one tablespoon at a time until the frosting reaches a smooth, spreadable consistency.
- Once the cake has cooled, spread the frosting evenly over the top. If you like, garnish with quartered lemon slices. Store the cake covered in the refrigerator until ready to serve.
Frequently Asked Questions
Do I need to use a 13 x 18 sheet pan, or will a different pan work?
A 13 x 18 pan gives you the classic sheet cake thickness and the quickest bake time. If you use a 9 x 13 pan, the batter will be thicker, so it will need a longer bake, and the cake will come out taller. Keep an eye on it and rely on a toothpick test rather than the clock.
What are a few easy ways to change it up without complicating the recipe?
You can add a little lemon zest to the batter for more fresh lemon flavor, or stir in a small handful of poppy seeds for a classic lemon-poppy twist. For the topping, try a shake of colorful sprinkles or a light dusting of confectioners’ sugar right before serving. These little touches add personality without changing the ease of the recipe.

Am I supposed to make the cake per the box instructions then add the lemon pie filling? I just made the cake adding ONLY the 4 eggs per the instructions, but the cake doesn’t look right at all. Please clarify. I really want to like this easy recipe.
Yes, it’s just the four eggs and the can of lemon pie filling.
