Ingredients
- 1 cup unsalted butter, softened: This is the base for a rich flavor.
- 1 cup granulated sugar: Adds the perfect sweetness to balance the tanginess of the lemon.
- 2 large eggs: These provide structure and moisture.
- 1 teaspoon vanilla extract: A touch of warmth to round out the flavors.
- 2 cups all-purpose flour: The backbone of our cookie slice.
- 1 teaspoon baking powder: Helps our slice rise beautifully.
- 1/2 teaspoon salt: Enhances all the flavors.

How to Make Lemon Cookie Slice Recipe
- Preheat your oven to 350°F (175°C) and grease a 9×13 inch baking dish.
- In a large bowl, cream together the softened butter and granulated sugar until light and fluffy. This should take about 2-3 minutes.
- Beat in the eggs, one at a time, followed by the vanilla extract. Make sure everything is well combined!
- In a separate bowl, whisk together the flour, baking powder, and salt.
- Gradually add the dry ingredients to the wet mixture, mixing until just combined. Don’t overmix; we want a tender slice!
- Stir in the lemon zest and fresh lemon juice until evenly distributed throughout the batter.
- Pour the batter into the prepared baking dish and spread it out evenly.
- Bake for 25-30 minutes, or until the edges are lightly golden and a toothpick inserted into the center comes out clean.
- Allow to cool completely in the baking dish before dusting with powdered sugar and slicing into squares.
Substitutions & Additions
If you’re looking to switch things up a bit, here are some fun ideas:
- Swap out the lemon for lime for a zesty twist!
- Add some poppy seeds for a classic lemon-poppy seed flavor.
- Mix in some white chocolate chips for extra sweetness.
- Top with a simple lemon glaze instead of powdered sugar for a different finish.
Tips for Success
Here are a few common pitfalls and my personal tips for making these lemon cookie slices perfect:
- Make sure your butter is softened, but not melted. This ensures the right texture.
- Don’t skip sifting the flour; it helps keep your batter light and fluffy.
- If you want to prepare ahead, you can make the batter a day in advance and refrigerate it. Just bring it back to room temperature before baking.
How to Store Lemon Cookie Slice Recipe
To keep your lemon cookie slices fresh:
- Store them in an airtight container at room temperature for up to 3 days.
- If you want to keep them longer, you can freeze the slices. Just wrap them tightly in plastic wrap and place them in a freezer-safe bag. They’ll last for up to 2 months!
FAQs
Can I use salted butter instead of unsalted? Yes, just omit the added salt in the recipe.
Can I make these gluten-free? Absolutely! You can substitute the all-purpose flour with a gluten-free blend.
How do I know when they are done baking? When the edges are lightly golden and a toothpick inserted comes out clean, they are ready!
