Step-by-Step Instructions
Let’s get baking! Follow these simple steps to create your own Lemon Sour Cream Sheet Cake:
- Preheat and Prep: Preheat your oven to 350°F (175°C). Prepare a 13×9 inch baking pan with baking spray or shortening and flour for easy release. Be sure to coat the pan evenly to prevent sticking.
- Combine Sugars and Eggs: In the bowl of a mixer, combine granulated sugar and brown sugar with eggs. Mix until well combined. This step is crucial for creating a light and airy texture.
- Incorporate Dry and Wet Ingredients: Add in flour and baking powder. As you mix, slowly pour in the milk, lemon juice, melted butter, oil, sour cream, vanilla extract, and lemon extract. Mix on low at first, then increase to medium until the batter is thoroughly combined. Avoid overmixing to prevent a tough cake.
- Bake: Pour the cake batter into the prepared pan and bake for 40 minutes, or until a toothpick inserted into the center comes out clean. The cake should be golden brown and spring back slightly when touched.
- Cool: Allow the cake to cool for 15 minutes. You can either let it cool completely in the baking pan or turn it out onto a cooling rack if you won’t be frosting it in the pan.
Lemon Sour Cream Frosting Recipe
No Lemon Sour Cream Sheet Cake is complete without its signature frosting. Here’s how to make it:
- Cream the Butter: In a mixing bowl, cream the room temperature butter until smooth and fluffy.
- Add Powdered Sugar: Gradually add the powdered sugar, mixing on low speed until combined. Be sure to scrape down the sides of the bowl to ensure even mixing.
- Incorporate Lemon Juice and Extract: Add the lemon juice and lemon extract. Mix until smooth and creamy.
- Adjust Consistency: If the frosting is too thick, add heavy cream, one tablespoon at a time, until you reach your desired consistency. For a richer flavor, consider adding a touch of cream cheese.
- Add Color (Optional): If desired, add a drop or two of yellow food coloring to enhance the lemon appearance.
Pro Tips for the Perfect Lemon Sour Cream Cake
Want to take your cake to the next level? Here are some pro tips:
- Use Room Temperature Ingredients: Room temperature ingredients emulsify better, resulting in a smoother batter and a more even bake.
- Don’t Overmix: Overmixing can lead to a tough cake. Mix until just combined.
- Measure Accurately: Baking is a science. Use a kitchen scale for precise measurements, especially for flour.
- Use Fresh Lemon Juice: Fresh lemon juice provides a brighter, more vibrant flavor than bottled juice.
- Cool Completely Before Frosting: Frosting a warm cake can cause it to melt and slide off. Ensure the cake is completely cool before frosting.
- Lemon Extract is Key: Don’t skip the lemon extract! It intensifies the lemon flavor and adds a delightful aroma.
Common Mistakes to Avoid
Even the best bakers make mistakes. Here are some common pitfalls to avoid when making this lemon sour cream cake:
- Using Cold Ingredients: As mentioned, cold ingredients don’t emulsify well.
- Overbaking: Overbaking can result in a dry cake. Use a toothpick to check for doneness.
- Undermixing: Undermixing can result in a dense, uneven cake.
- Not Greasing the Pan Properly: This can cause the cake to stick to the pan. Be sure to grease and flour thoroughly.
- Adding too much lemon juice: Too much lemon juice can affect the structure of the cake and make it too tart.

- Lemon Poppy Seed: Add 2 tablespoons of poppy seeds to the batter for a subtle crunch and nutty flavor.
