Let’s gather our ingredients to make these scrumptious lemon raspberry bars! You’ll want to have everything prepared and ready to go. Here’s what you need:

  • 2 cups raspberries (250 g), fresh or frozen, rinsed and drained
  • 2 1/4 cups all-purpose flour (281 g), sifted
  • 1/2 cup granulated sugar (100 g)
  • 1 tablespoon cornstarch
  • 1/4 teaspoon salt
  • 1 cup unsalted butter (226 g), melted and slightly cooled
  • 1 1/2 cups granulated sugar (300 g), for the filling
  • 1/3 cup cornstarch (40 g), for the filling

Make sure to measure everything accurately. Fresh ingredients make all the difference, especially that vibrant lemon juice and those juicy raspberries! You’ll see how they come together in this delightful recipe.

How to Prepare Lemon Raspberry Bars

Alright, let’s roll up our sleeves and get into the nitty-gritty of making these lemon raspberry bars! I promise you, the process is as delightful as the final product. Follow along, and you’ll have a batch of these beauties in no time!

Prepare the Raspberry Purée

First things first, we need that luscious raspberry purée! Start by blending your 2 cups of raspberries until they’re smooth. You can use a regular blender or an immersion blender—whatever you’ve got handy! Once blended, it’s time to strain the purée through a fine sieve to remove those pesky seeds. It’s optional, but trust me, you’ll want that smooth texture in your bars.

Next, transfer the strained purée to a small saucepan and simmer it over low-medium heat. You want to reduce it until it thickens up to about 1/4–1/3 cup, which should take around 15–20 minutes. Keep an eye on it and stir occasionally to prevent sticking. Once it’s thickened, remove it from heat and let it cool while you prep the rest!

Make the Shortbread Base

Now, let’s tackle that buttery shortbread base! In a mixing bowl, combine 2 1/4 cups of sifted all-purpose flour, 1/2 cup of granulated sugar, 1 tablespoon of cornstarch, and 1/4 teaspoon of salt. Give it a good whisk to combine everything. Then, stir in 1 cup of melted butter until a thick dough forms. This is the point where you can really feel that delicious buttery goodness coming together.

Press the dough evenly into the bottom of your lined 9×13 inch pan, making sure to create a slight edge around the sides. This will help contain that glorious filling! Pop it into the oven and bake for about 20–25 minutes, or until it’s lightly golden. Pro tip: keep an eye on it and use a toothpick to check for doneness—if it comes out clean, you’re good to go!

Prepare the Lemon Raspberry Filling

With the shortbread base baking away, let’s whip up that zesty lemon raspberry filling! In a large bowl, whisk together 1 1/2 cups of granulated sugar and 1/3 cup of cornstarch. Once combined, crack in 6 large eggs, whisking them in until everything is nicely blended. Now for the fun part—gradually whisk in your cooled raspberry purée and 3/4 cup of fresh lemon juice. This order is super important to avoid any lumps, so take your time and mix it well!

Bake the Bars

Pour that vibrant mixture over your warm shortbread base, smoothing it out gently. Then, it’s back to the oven for another 20–25 minutes. You want the filling to be set but still a little jiggly in the center—this means it’s perfectly creamy. To check for doneness, give the pan a gentle shake; if the center wobbles slightly but the edges look firm, you’re all set!

Cooling and Serving

Once baked, let the bars cool at room temperature for about an hour. Then, pop them in the fridge for at least 2 hours to really let those flavors deepen and set up nicely. When you’re ready to serve, lift them out of the pan using the parchment overhang. Slice them with a sharp knife for clean edges, and store any extras in an airtight container in the fridge. They’ll stay fresh for up to 5 days, but I doubt they’ll last that long! Enjoy every tangy, sweet bite!

Tips for Success

Now that you’re ready to dive into making these lemon raspberry bars, let me share some tried-and-true tips for ensuring they turn out absolutely perfect every time. These little nuggets of wisdom can make all the difference!

Use Fresh Ingredients

First off, always opt for fresh ingredients when possible. Fresh lemons and raspberries pack a flavor punch that really elevates these bars. If you can squeeze your own lemon juice, do it! Those store-bought bottles just don’t compare, and that vibrant zest will shine through in your final product.

Temperature Matters

Make sure your ingredients are at the right temperature! For the eggs, you want them at room temperature for easy mixing. Cold eggs can cause lumps in your filling, and we definitely don’t want that! Similarly, let your melted butter cool slightly before adding it to the dry ingredients to avoid cooking the eggs.

Keep an Eye on Baking Times

Every oven is a little different, so keep a close watch on your bars as they bake. Start checking for doneness a few minutes before the minimum baking time. Remember, the filling should be set but still have a little jiggle in the center. If you overbake them, they can become dry, and we’re aiming for that creamy, luscious texture!

Don’t Skip the Cooling Time

Letting the bars cool completely before slicing is crucial for the best texture. I know it’s tempting to dig in right away, but trust me—give them at least an hour at room temperature and then a couple of hours in the fridge. This helps the filling to firm up nicely, making it easier to slice and ensuring that each bite is just right!

Experiment with Presentation

Finally, don’t be afraid to get creative with how you serve these bars! A simple dusting of powdered sugar on top adds a lovely touch, or you could add some fresh raspberries and lemon slices for garnish. It’s all about making them as beautiful as they are delicious!

With these tips in your back pocket, you’ll be well on your way to creating lemon raspberry bars that not only taste amazing but look stunning too. Happy baking!

Storage & Reheating Instructions

So, you’ve whipped up a batch of these delightful lemon raspberry bars, and now you want to keep them fresh and tasty for later. No problem at all! Storing these bars correctly is key to preserving their flavor and texture.

Once your bars have cooled completely, lift them out of the pan using the parchment paper overhang. Slice them into squares or rectangles, whichever you prefer. To store them, place the bars in an airtight container lined with parchment paper, making sure to separate layers with additional parchment if needed. This helps prevent them from sticking together.

You can keep them in the refrigerator for up to 5 days. They actually taste even better after a day or two as the flavors meld together beautifully!

If you want to enjoy them warm, you can reheat individual bars in the microwave. Just pop one in for about 10-15 seconds—you want it warm but not hot. Be careful not to overdo it, or they may lose that lovely creamy texture we all adore. If you’re serving them for a gathering, you can also place them in a preheated oven at 350°F (175°C) for about 5-10 minutes to warm them up a bit.

And there you have it! With these simple storage and reheating tips, you can enjoy your lemon raspberry bars at their best, whether freshly made or as leftovers. Happy indulging!

FAQ Section

Ah, I love that you’re curious about these lemon raspberry bars! Let’s dive into some common questions that pop up, so you can feel confident making this delicious treat.

Can I substitute other fruits for the raspberries?

Absolutely! While raspberries are a star in this recipe, you can easily swap them out for blueberries, strawberries, or even blackberries. Just remember that the flavor profile will change a bit, but it’ll still be delicious! If you’re using a fruit that’s a bit sweeter, you might want to adjust the sugar in the filling slightly.

What can I use instead of cornstarch?

If you don’t have cornstarch on hand, you can use an equal amount of all-purpose flour as a thickener. It won’t provide quite the same texture, but it’ll still work in a pinch. Just keep in mind that the filling might be a tad less silky.

How long can I store these bars?

These lemon raspberry bars can be stored in the refrigerator for up to 5 days. They actually taste even better after a day or two as the flavors meld together! Just make sure to keep them in an airtight container to maintain their freshness.

Can I freeze lemon raspberry bars?

Yes, you can! Just make sure the bars are completely cooled and cut into squares before freezing. Place them in a single layer in a freezer-safe container, separating layers with parchment paper. They’ll keep well for up to 3 months. When you’re ready to enjoy them, simply thaw in the refrigerator overnight or let them sit at room temperature for a bit.

What if I want to make a larger batch?

No worries! You can easily double the recipe. Just make sure to use a larger baking dish, like a 12×17 inch pan, and keep an eye on the baking time as it may vary slightly. You want to ensure that the filling is set but still has that lovely jiggle in the middle.
