Key Ingredients for Lemon Crumb Bars
To make Lemon Crumb Bars, there are a few key ingredients that truly shine in this recipe. Understanding each one will help you appreciate the flavor and texture they bring to the table.
- Lemon: Fresh lemons are essential for this recipe. You’ll use both the zest and juice to give the Lemon Crumb Bars a bold, citrusy kick. The zest, in particular, adds an aromatic element that brightens the overall flavor.
- Sweetened Condensed Milk: This thick, sugary milk is the base for the creamy lemon filling in Lemon Crumb Bars. It’s sweet, rich, and gives the filling a velvety smooth texture.
- Oats: Rolled oats are key to creating the crumbly texture for both the crust and the topping in Lemon Crumb Bars. Old-fashioned oats are preferred for their thicker texture, but quick oats can also work in a pinch.
- Brown Sugar: Dark or light brown sugar can be used, but dark brown sugar has a richer, molasses-like flavor that adds depth to the crumble topping in Lemon Crumb Bars.
- Butter: Unsalted butter helps bind the crust and topping together. It’s essential for the signature richness that makes Lemon Crumb Bars irresistible.
- Baking Powder: A small amount of baking powder ensures that the crust and crumble topping remain light and not too dense.
What Makes This Lemon Crumb Bars Recipe Different?
When comparing various Lemon Crumb Bars recipes, a few things stand out about this one. Many recipes suggest using premade crusts or omit certain ingredients, but this version maximizes flavor and texture with homemade components.
Here are the key differences:
- Use of Fresh Lemons: Some recipes settle for bottled lemon juice, but fresh lemons make all the difference. The zest, in particular, gives the Lemon Crumb Bars an enhanced lemon flavor that you can’t replicate with processed juice.
- Double-Duty Crumble: The brown sugar-oat crumble serves as both the crust and the topping in Lemon Crumb Bars, simplifying the process while maintaining the perfect balance of texture.
- Simple Ingredients with Big Impact: No need for complicated or hard-to-find ingredients; everything you need for these Lemon Crumb Bars is probably already in your kitchen.
Nutritional Benefits of Lemon Crumb Bars
While Lemon Crumb Bars are certainly a treat, it’s also important to note the nutritional benefits they offer, especially when using whole ingredients like oats and fresh lemon juice.
- Lemon: Lemons are rich in Vitamin C, which supports the immune system and promotes healthy skin.
- Oats: Oats are high in fiber, which can help with digestion and provide a long-lasting energy boost.
- Butter: While it’s high in fat, unsalted butter provides necessary fats for a balanced diet when consumed in moderation.
These Lemon Crumb Bars, when eaten in moderation, can be a satisfying dessert that also provides a small dose of nutritional benefits.
The Perfect Lemon Crumb Bars Recipe
Now that you know what makes Lemon Crumb Bars so great, let’s dive into the recipe.
Ingredients:
- 8 tablespoons unsalted butter, cut into pieces
- 3/4 cup dark or light brown sugar (packed)
- 3/4 teaspoon baking powder
- 3/4 teaspoon kosher salt (divided)
- 1 1/4 cups old-fashioned rolled oats
- 1 cup all-purpose flour
- 2 large or 3 medium lemons (zested and juiced)
- 1 (14-ounce) can sweetened condensed milk
Instructions:
- Preheat the Oven: Arrange a rack in the middle of the oven and preheat it to 350°F (175°C). Line an 8×8-inch baking pan with parchment paper, leaving enough overhang on all sides to lift the bars out once they’re done.
- Melt the Butter: Place the butter in a microwave-safe bowl and melt it in the microwave for 40-60 seconds in 20-second bursts. Alternatively, you can melt the butter on the stovetop and then pour it into a large bowl.
- Prepare the Crumble Mixture: Add brown sugar, baking powder, and 1/2 teaspoon salt to the melted butter. Stir to combine. Then add oats and all-purpose flour and mix until there are no dry spots. Set aside 1 cup of this mixture for topping.
- Bake the Crust: Press the remaining crumble mixture into the prepared pan to form an even layer. Bake in the preheated oven for 12-14 minutes or until lightly golden and fragrant. Remove from the oven and allow it to cool slightly.
- Prepare the Lemon Filling: While the crust is baking, grate the zest of the lemons into a bowl. Then, juice the lemons until you have about 1/2 cup of lemon juice. Add the lemon zest, lemon juice, sweetened condensed milk, and the remaining 1/4 teaspoon of salt into the bowl. Whisk until smooth.
- Assemble and Bake: Pour the lemon filling over the slightly cooled crust. Evenly sprinkle the reserved crumble mixture on top. Return the pan to the oven and bake for 22-24 minutes, or until the edges are golden brown and the filling is set. Let the bars cool completely, then refrigerate for 30 minutes if you want the filling to firm up even more.
- Cut and Serve: Once completely cool, lift the bars from the pan using the parchment overhang and cut them into 12 even pieces.
Tips for Perfecting Your Lemon Crumb Bars
Making Lemon Crumb Bars is easy, but a few tips can ensure that they turn out perfectly every time. Let’s explore some common mistakes and how to avoid them, along with a few tricks that will elevate your bars to the next level.
1. Use Fresh Lemons, Not Bottled Juice
While it might be tempting to reach for bottled lemon juice for convenience, fresh lemons are a must for Lemon Crumb Bars. Fresh zest adds a fragrant, zesty note that bottled lemon juice can’t replicate. Additionally, using fresh lemon juice ensures that you’re getting the full citrusy punch that these bars are known for.
To zest a lemon, simply use a fine grater or zester. Make sure you don’t zest too deeply, as the white pith can impart bitterness to your Lemon Crumb Bars. Always zest before juicing, as it’s easier to zest a whole lemon.
2. Don’t Skip the Cooling Time
Allow your Lemon Crumb Bars to cool completely in the pan before slicing them. If you cut them too early, the filling might still be too soft and runny. If you prefer firmer bars, refrigerate them for 30 minutes after they’ve cooled to room temperature. This step will help set the filling and make slicing easier.
3. Use Parchment Paper for Easy Removal
One of the easiest ways to ensure your Lemon Crumb Bars come out of the pan without a fuss is by using parchment paper. Line your pan with parchment paper, allowing it to hang over the sides, creating a “sling” to lift the bars out once they’re done. This method makes cutting and serving so much easier and prevents your bars from sticking to the pan.
4. Adjust the Sweetness to Your Liking
The sweetness of Lemon Crumb Bars can vary based on the type of brown sugar and sweetened condensed milk you use. Dark brown sugar adds a deeper, richer flavor, while light brown sugar provides a more subtle sweetness. If you prefer a less sweet filling, consider using a little less sweetened condensed milk or adding a squeeze of fresh lemon juice for more tang.
5. Add a Touch of Vanilla or Almond Extract
For an added layer of flavor, try incorporating a small amount of vanilla extract or almond extract into the lemon filling. This subtle addition can enhance the depth of flavor in your Lemon Crumb Bars and bring out the richness of the brown sugar and oats.
Common Mistakes to Avoid in Making Lemon Crumb Bars
While making Lemon Crumb Bars is relatively simple, there are a few common mistakes that can affect the final outcome. Here are some to watch out for:
Mistake 1: Overmixing the Crumble Mixture
It can be tempting to mix the crumble ingredients vigorously, but overmixing can lead to a dense, tough crust and topping. Instead, mix just until the ingredients are combined, ensuring the crumble retains its light, airy texture.
Mistake 2: Underbaking or Overbaking the Crust
The crust of Lemon Crumb Bars should be lightly golden brown. If it’s underbaked, it might become soggy once the filling is added. Overbaking can lead to a dry crust that lacks the buttery softness we want. Keep an eye on the crust as it bakes and remove it from the oven as soon as it’s golden and fragrant.
Mistake 3: Not Using Enough Lemon Zest
The lemon zest is crucial in creating a bright, zesty flavor in Lemon Crumb Bars. Don’t skip this step! Use a fine grater or zester to get the most out of your lemons. A generous amount of zest will elevate the flavor and give your bars that signature citrus punch.
Mistake 4: Not Letting the Bars Cool Properly
Cooling your Lemon Crumb Bars is key to getting the right texture. If you cut into them too soon, the filling may spill out and make a mess. Allow the bars to cool to room temperature, and then chill them in the fridge for 30 minutes if you want firmer bars.
Variations and Customizations for Lemon Crumb Bars
One of the great things about Lemon Crumb Bars is how customizable they are. While the original recipe is perfect as-is, you can experiment with different flavors and textures. Here are a few ideas to take your Lemon Crumb Bars to the next level:
1. Berry Lemon Crumb Bars
Add some fresh or frozen berries to your Lemon Crumb Bars for a colorful and flavorful twist. Blueberries, raspberries, or strawberries would all pair wonderfully with the lemon filling. Simply fold in a handful of berries before baking, or sprinkle them on top before adding the crumble.
2. Coconut Lemon Crumb Bars
For a tropical twist, try adding shredded coconut to the crumble topping or the lemon filling. The coconut will add a chewy, sweet texture that complements the tangy lemon flavor.
3. Lemon Crumb Bars with a Shortbread Crust
If you prefer a more buttery and tender base, substitute the oat crust with a shortbread crust. You can make a simple shortbread by mixing butter, sugar, and flour, then pressing it into the pan before baking. This variation will give your Lemon Crumb Bars a melt-in-your-mouth texture.
4. Gluten-Free Lemon Crumb Bars
For a gluten-free version of Lemon Crumb Bars, simply substitute the all-purpose flour with a gluten-free flour blend. You can also replace the oats with gluten-free rolled oats to ensure that the bars are completely gluten-free.
Serving and Storing Lemon Crumb Bars
Lemon Crumb Bars can be stored at room temperature for up to 5 days. If you want to keep them fresh for a longer period, store them in an airtight container in the fridge. The flavors will only get better after a day or two, making them perfect for meal prepping or for bringing to a gathering.
To serve, simply cut the bars into squares and enjoy! They are great on their own or served with a scoop of vanilla ice cream or a dollop of whipped cream. Lemon Crumb Bars can also be dusted with powdered sugar for an added touch of sweetness and elegance.
