Ingredients
Main Ingredients
- 1 cup unsalted butter, softened
- ½ cup powdered sugar
- 2 cups all-purpose flour
- ¼ teaspoon salt
For this recipe, you need a few key items. Start with unsalted butter. It gives the bars a rich taste. Use powdered sugar, which helps the shortbread stay soft. All-purpose flour is the base for the shortbread, and salt brings out the flavors.
Flavor Elements
- Zest of 1 lemon
- ½ cup granulated sugar
- Juice of 1 lemon
- 1 tablespoon cornstarch
- 1 teaspoon vanilla extract
Next, you will add flavor. Lemon zest adds a bright touch. Granulated sugar balances the tartness from the lemon juice. Cornstarch gives the filling a nice, smooth texture. Don’t forget the vanilla extract for warmth and depth.
Fresh Additions
- 1 cup fresh raspberries (or frozen, thawed)
The best part of these bars is the raspberries. Fresh ones add a juicy burst. They mix well with the lemon, making each bite a treat. If fresh raspberries are not available, use frozen ones. Just let them thaw and drain before adding.

Step-by-Step Instructions
Preparing the Shortbread Base
1. Preheat your oven to 350°F (175°C). Grease a 9x9 inch baking dish or line it with parchment paper. This makes it easy to lift out the bars later.
2. In a large bowl, cream 1 cup of softened unsalted butter with ½ cup of powdered sugar. Mix until it’s light and fluffy. This step adds air, making your shortbread soft.
3. Slowly add 2 cups of all-purpose flour and ¼ teaspoon of salt. Mix until a soft dough forms. Then, add the zest of 1 lemon. This gives your shortbread a bright flavor.
Baking the Shortbread
1. Press the shortbread mixture evenly into the bottom of your prepared dish. Make sure it’s a smooth layer.
2. Bake for 18-20 minutes. You want it to be lightly golden around the edges. Remove it from the oven and let it cool a bit. This creates a nice base for your filling.
Making the Raspberry Lemon Filling
1. In another bowl, whisk together ½ cup of granulated sugar, 2 large eggs, the juice of 1 lemon, 1 tablespoon of cornstarch, and 1 teaspoon of vanilla extract. Mix until it’s smooth and well combined.
2. Gently fold in 1 cup of fresh raspberries. Be careful not to crush them. You want to keep those lovely raspberry bits whole.
3. Pour the raspberry lemon filling over the baked shortbread. Spread it evenly across the top.
Now, you're ready to bake again!
Tips & Tricks
Shortbread Perfection
To make the best shortbread, baking time and temperature are key. Set your oven to 350°F (175°C) for even cooking. Bake the shortbread for 18-20 minutes. Look for a light golden color around the edges. This gives the bars a nice crunch.
For an even texture, press the shortbread mixture firmly into the dish. Make sure there are no air pockets. This helps create a smooth base. Once baked, allow it to cool slightly before adding the filling.
Raspberry Handling
When using fresh raspberries, pick those that are firm and bright. They will give the best flavor. If you use frozen raspberries, let them thaw first. Drain any extra liquid to avoid a soggy filling. Gently fold them into the mixture to keep them whole. This adds bursts of flavor to every bite.
Enhancing Presentation
To make your bars look extra special, dust them with powdered sugar before serving. This adds a sweet touch and makes them look fancy. For a pop of color, garnish with a few fresh raspberries on top. A sprinkle of lemon zest also adds a nice touch. These small details will make your dessert stand out.

Variations
Flavor Swaps
You can easily switch the raspberries for other berries. Blueberries or strawberries work great. Each berry adds its unique taste. Blueberries bring a sweet burst, while strawberries add a mild tang. Feel free to mix berries for a colorful twist. This change keeps the bars fresh and fun.
Dietary Adjustments
If you need a gluten-free option, use almond flour or a gluten-free blend. These alternatives work well in baking. For a vegan version, swap the butter for coconut oil. You can use flax eggs in place of regular eggs. Mix 1 tablespoon of ground flaxseed with 2.5 tablespoons of water. Let it sit until it thickens. These changes make the bars suitable for many diets.
Servings and Sizes
You can easily adjust the recipe for more or fewer bars. To make 24 bars, double the ingredients. Use a larger pan to bake them. For fewer bars, cut the recipe in half. A smaller pan will help with even baking. Adjust baking times as needed. Enjoy your delicious bars, no matter the size!
Storage Info
Proper Storage Techniques
To keep your Raspberry Lemon Shortbread Bars fresh, store them in the fridge. Place the bars in an airtight container. This helps keep moisture out and flavor in. Use parchment paper between layers to avoid sticking. To prevent sogginess, let the bars cool completely before covering them. If they are warm, condensation can form and make them mushy.
Freezing Instructions
Freezing these bars is easy. First, cut them into squares. Then, wrap each piece in plastic wrap. Place the wrapped bars in a freezer-safe bag or container. Make sure to label the container with the date. For the best taste and texture, thaw the bars in the fridge overnight. Avoid thawing them at room temperature to keep their shape and flavor. Enjoy your sweet and tangy treat any time!
