What Ingredients You Will Need

This recipe uses simple, wholesome ingredients to deliver bold flavor and satisfying texture without the fuss. Here’s what you’ll need:

For the crust and crumble:

• 1 ½ cups (190g) all-purpose flour
• ½ cup (100g) granulated sugar
• ½ teaspoon baking powder
• ½ teaspoon salt
• ½ cup (115g) unsalted butter, cold and cubed
• 1 large egg yolk

For the lemon filling:

• 1 can (14 oz/396g) sweetened condensed milk
• ½ cup (120ml) freshly squeezed lemon juice (about 2 large lemons)
• 2 teaspoons lemon zest (optional but recommended for added flavor)
• 2 large egg yolks
• ½ teaspoon vanilla extract

If you want to make these bars gluten-free, swap the all-purpose flour for almond flour. You can also use dairy-free condensed milk for a vegan version. These ingredients are super adaptable, so don’t be afraid to experiment!

Equipment Needed

• Mixing bowls: One large and one medium.
• Whisk: For blending the lemon filling.
• Pastry cutter or fork: To cut the butter into the dry ingredients for the crust.
• 9×9-inch baking dish: A square pan works best for even layers.
• Parchment paper: Makes removing the bars from the pan a breeze.
• Microplane or zester: For grating fresh lemon zest.

If you don’t have a pastry cutter, a fork works just fine to break up the butter into the flour mixture. And if you don’t have a microplane for zesting lemons, a box grater with fine holes will do the trick!

Preparation Method

1. Preheat your oven to 350°F (175°C). Line a 9×9-inch baking dish with parchment paper, leaving some overhang for easy removal later.
2. In a large mixing bowl, combine the flour, sugar, baking powder, and salt. Whisk to incorporate.
3. Add the cold, cubed butter to the dry ingredients. Using a pastry cutter or fork, cut the butter into the mixture until it resembles coarse crumbs.
4. Mix in the egg yolk. The mixture will still be crumbly but should clump together when pressed.
5. Press half of the crumb mixture into the bottom of the prepared baking dish to form the crust. Use your hands or the back of a spoon to press it down firmly and evenly.
6. Bake the crust for 10 minutes, or until it starts to set and looks slightly golden. Remove from the oven and set aside to cool slightly.
7. While the crust is baking, prepare the lemon filling. In a medium mixing bowl, whisk together the sweetened condensed milk, lemon juice, lemon zest, egg yolks, and vanilla extract until smooth.
8. Pour the lemon filling over the partially baked crust, spreading it out evenly with a spatula.
9. Sprinkle the remaining crumb mixture evenly over the top of the lemon filling to create the crumble layer.
10. Return the pan to the oven and bake for an additional 25–30 minutes, or until the crumble is golden brown and the filling is set.
11. Allow the bars to cool completely in the pan before lifting them out using the parchment paper overhang. Slice into squares or rectangles and serve!

Cooking Tips & Techniques

Here are some handy tips to make sure your lemon crumb bars turn out perfectly:

• Keep the butter cold: Cold butter is key for achieving a crumbly texture. If the butter starts to soften, pop it in the fridge for a few minutes before continuing.
• Don’t skip the parchment paper: This step makes removing the bars so much easier and prevents them from sticking to the pan.
• Use fresh lemons: Freshly squeezed lemon juice and zest provide a vibrant flavor that you just can’t replicate with bottled juice.
• Don’t overbake: Keep an eye on the bars during the second bake. The filling should be set but still slightly jiggly when you remove it from the oven.
• Cut cleanly: Use a sharp knife to slice the bars, cleaning it between cuts for neat edges.

Variations & Adaptations

Want to mix things up? Here are some fun ideas for variations:

• Swap the citrus: Replace lemon juice and zest with lime or orange for a different flavor profile.
• Make it gluten-free: Use almond flour instead of all-purpose flour for a gluten-free option. The texture will be slightly different but still delicious.
• Berry swirl: Add a swirl of raspberry or blueberry jam to the lemon filling before topping with crumble for a fruity twist.
• Make it vegan: Substitute dairy-free condensed milk and use a flaxseed egg in place of the egg yolk.
• Add a nutty crunch: Mix chopped walnuts or pecans into the crumble topping for added texture.

Serving & Storage Suggestions

These lemon crumb bars are best served slightly chilled or at room temperature. Pair them with a cup of tea or coffee for the ultimate treat. If you’re hosting, arrange them on a pretty serving platter for a touch of elegance.

To store, place the bars in an airtight container and refrigerate for up to 5 days. They also freeze beautifully—just wrap each bar individually and store them in a freezer-safe bag or container for up to 3 months. To thaw, simply leave them in the fridge overnight or at room temperature for a couple of hours. If you prefer them warm, pop them in a preheated oven at 300°F (150°C) for a few minutes.

Nutritional Information & Benefits

These lemon crumb bars are a delightful balance of indulgence and lightness. Each serving is approximately 200 calories, with a nice mix of carbohydrates, healthy fats, and a touch of protein from the egg yolks. Lemon is rich in vitamin C, which supports your immune system and adds a burst of fresh flavor.

If you’re looking for a lower-calorie option, you can use a sugar substitute or reduced-fat sweetened condensed milk. Note that this recipe contains dairy and gluten, so it’s not suitable for those with allergies unless substitutions are made.

FAQs

Can I use store-bought lemon juice instead of fresh?

Fresh lemon juice is highly recommended for the best flavor. Bottled lemon juice may taste less vibrant and slightly artificial.

Can I double the recipe for a larger batch?

Absolutely! Simply use a larger baking pan and double the ingredients. Adjust the baking time as needed, adding a few extra minutes if required.

What’s the best way to zest a lemon?

Use a microplane or fine grater to scrape the outer yellow layer of the lemon. Avoid the white pith underneath, as it can be bitter.

Can I make these bars ahead of time?

Definitely! These bars store well in the fridge for several days, making them perfect for preparing a day or two in advance.

How can I make these less sweet?

You can reduce the sugar in the crust slightly or add an extra tablespoon of lemon juice to the filling for more tartness.
