Ingredients
List of Ingredients
– 1 cup all-purpose flour
– 1/4 cup powdered sugar
– 1/2 cup unsalted butter, melted
– 1 cup granulated sugar
– 2 large eggs
– 1/3 cup freshly squeezed lemon juice (about 2-3 lemons)
– Zest of 1 lemon
– 1/2 teaspoon baking powder
– 1/4 teaspoon salt
– 1/2 cup fresh raspberries, crushed (plus extra for garnish)
– 1 tablespoon cornstarch
Ingredient Substitutions

– You can swap fresh raspberries for strawberries or blueberries if you prefer. These fruits also mix nicely with lemon.

Step-by-Step Instructions
Preparing the Crust
First, preheat your oven to 350°F (175°C). Next, grab an 8×8 inch baking dish and line it with parchment paper. Leave some paper hanging over the edges. This makes it easy to lift out the bars later. In a medium bowl, whisk together 1 cup of all-purpose flour and 1/4 cup of powdered sugar. Then, pour in 1/2 cup of melted unsalted butter. Mix until the texture looks like coarse crumbs. Press this mixture firmly into the bottom of the baking dish.
Making the Lemon Filling
In a large bowl, whisk together 1 cup of granulated sugar, 2 large eggs, 1/3 cup of freshly squeezed lemon juice, the zest of 1 lemon, 1/2 teaspoon of baking powder, and 1/4 teaspoon of salt. Whisk until the mixture is smooth. Pour this tangy lemon filling over the slightly cooled crust.
Adding the Raspberry Swirl
In a small bowl, mix 1/2 cup of crushed fresh raspberries with 1 tablespoon of cornstarch. Stir gently to coat the raspberries. Now, create a swirl effect by gently adding the raspberry mixture into the lemon filling. Use a gentle swirling motion. Be careful not to overmix.
Baking Process
Place the baking dish back into the oven. Bake for 20-25 minutes. The center should feel firm to the touch when done.
Cooling and Cutting
Once baked, take the dish out of the oven. Let the bars cool completely in the dish. Use the parchment paper to lift them out. Place them on a cutting board. Cut into 12 equal squares. For a lovely finish, dust the tops with extra powdered sugar before serving.
Tips & Tricks
Perfecting the Raspberry Swirl
To get that beautiful marbling effect, swirl the raspberry mixture gently into the lemon filling. Use a knife or a skewer to create patterns without mixing too much. This keeps the colors distinct and makes your bars pretty. Avoid overmixing. If you mix too much, the colors blend and lose their charm.
Storage Recommendations
Store leftover lemon bars in an airtight container. Keep them in the fridge for up to five days. If you want to freeze them, wrap each bar in plastic wrap, then place them in a freezer bag. They can last up to three months in the freezer. Just thaw them in the fridge before serving for the best taste.
Serving Suggestions
For a lovely presentation, dust the tops with powdered sugar right before serving. Arrange the bars on a nice platter and add fresh raspberries and mint leaves for color. Pair these bars with iced tea or lemonade for a refreshing treat. They make a great addition to any summer picnic or party!
Pro Tips
- Chill the Bars: For a firmer texture and easier cutting, refrigerate the lemon bars for at least 2 hours after they cool completely.
- Fresh Lemon Juice: Always use freshly squeezed lemon juice for the best flavor. Bottled lemon juice can be overly acidic and may alter the taste.
- Raspberry Swirl Technique: Gently swirl the raspberry mixture into the lemon filling for a beautiful marbled effect, but don’t overmix to keep the distinct layers.
- Serving Suggestions: Serve these lemon bars chilled with a dollop of whipped cream or a scoop of vanilla ice cream for an extra indulgent treat.
Variations
Flavored Lemon Bars
You can change the flavor of your lemon bars easily. Adding other fruit purees works well. Try mango, strawberry, or blueberry for a twist. Each fruit adds its own charm and taste. You can also infuse the lemon filling with herbs. Mint or basil can add a refreshing layer to the flavor. Just chop the herbs finely and mix them in.
Healthier Versions
Want a healthier treat? Use whole grain flour instead of all-purpose flour. This swap adds fiber and makes the bars more filling. You can also cut down on sugar. Try using honey or maple syrup instead. These sweeteners can make the bars taste great without the extra sugar.
Seasonal Variations
Seasonal berries can change the taste of your bars. In summer, use fresh blueberries or strawberries. In fall, add pumpkin puree for a spicy twist. You can also adapt flavors for holidays. For example, add a dash of cinnamon during the winter months for warmth. Each season offers new ways to enjoy these lemon bars.
