Ingredients
- 2 cups all-purpose flour
- 1 cup granulated sugar
- ¼ teaspoon salt
- ½ teaspoon baking powder
- 1 cup unsalted butter, cold and cubed
- 2 large eggs
- 1 teaspoon vanilla extract
- 1 can (14 ounces) sweetened condensed milk
- ½ cup fresh lemon juice (about 2-3 lemons)
- 1 tablespoon lemon zest
- Powdered sugar for dusting (optional)
Instructions
- Preheat your oven to 350°F (175°C). Line a 9x13-inch baking pan with parchment paper, leaving a slight overhang for easy removal.
- In a large bowl, whisk together the flour, granulated sugar, salt, and baking powder.
- Add the cold, cubed butter to the dry ingredients. Using a pastry blender or your fingers, cut the butter in until the mixture resembles coarse crumbs.
- Add the eggs and vanilla extract to the mixture. Stir just until combined-the dough should be crumbly.
- Set aside 1 ½ cups of the crumb mixture for the topping. Press the remaining crumb mixture evenly into the bottom of the prepared baking pan to form the crust.
- In a separate bowl, whisk together the sweetened condensed milk, lemon juice, and lemon zest until smooth and creamy.
- Pour the lemon filling over the crust in the pan, spreading it evenly with a spatula.
- Sprinkle the reserved crumb mixture evenly over the top of the lemon filling.
- Bake in the preheated oven for 25-30 minutes, or until the topping is golden and the filling is just set.
- Remove the pan from the oven and allow the bars to cool completely in the pan on a wire rack.
- Once cooled, lift the bars out using the parchment paper overhang. Cut into squares or rectangles.
- Dust with powdered sugar if desired, and serve.
Nutritional Information
Lemon Crumb Bars, while incredibly delicious, should be enjoyed as an occasional indulgence due to their sweet and buttery nature. Each bar, when cut into 24 pieces, yields approximately 180 to 220 calories, depending on the size and exact division.
The bars contain about 8-10 grams of fat, primarily from the butter and eggs, which gives them their rich, tender crumb. Sugars are present both from the granulated sugar and the sweetened condensed milk, totaling around 18-22 grams per serving.
While these bars are predominantly a treat, they do offer a bit of nutritional value thanks to the fresh lemon juice and zest, which provide vitamin C and some antioxidants.
The protein content per bar hovers around 2-3 grams, and they have a modest amount of dietary fiber from the all-purpose flour. Since they are relatively high in sugars and fats, portion control is key.
Those with dietary restrictions can consider making substitutions such as using light condensed milk or a whole grain flour to reduce the calorie density and increase nutrients.
Regardless, Lemon Crumb Bars can be part of a balanced overall diet when eaten in moderation, and they are best enjoyed as special-occasion bites that satisfy a citrusy sweet tooth.
Wine and Beverage Pairings
Lemon Crumb Bars pair beautifully with a variety of beverages. For a refreshing complement, serve them with a cold glass of iced tea or homemade lemonade to emphasize the citrus notes.
If you prefer a warm option, classic Earl Grey or chamomile tea enhances the lemon flavor and balances the sweetness.
For those seeking an alcoholic pairing, a lightly chilled glass of Moscato d'Asti or a vibrant Sauvignon Blanc works wonderfully, as their fruity and floral undertones match the bright citrus of the bars.
Coffee lovers can enjoy the bars with a medium-roast brew, which contrasts the tartness of the lemon with rich, mellow notes. No matter your choice, these drinks make enjoying Lemon Crumb Bars even more delightful.
Cooking Tips and Variations
To achieve the best Lemon Crumb Bars, it's essential to start with fresh, quality ingredients, especially the lemons. Always use freshly squeezed lemon juice and freshly grated zest for the most vibrant, natural flavor.
Cold butter ensures a tender, crumbly base and topping, so avoid letting it sit at room temperature before incorporating. If you lack a pastry blender, two forks or simply your hands will do the job for cutting the butter into the flour mixture.
For those craving extra tang, you can increase the amount of lemon zest slightly or add a teaspoon of lemon extract to the filling. Looking for a nutty crunch? Add ½ cup of finely chopped toasted almonds or pecans to the crumb topping for an added texture.
For a gluten-free version, substitute the all-purpose flour with a high-quality gluten-free blend. The sweetness level can also be adjusted: if you prefer bars that lean more tart than sweet, try reducing the sugar in the crust mixture by a quarter.
To store Lemon Crumb Bars, keep them in an airtight container at room temperature for up to three days or refrigerate for up to a week. For longer storage, freeze the bars (separated with parchment paper) for up to two months, thawing at room temperature before serving.
Serving Suggestions
Lemon Crumb Bars are as versatile in presentation as they are in flavor. They are best served at room temperature, which brings out the full depth of their buttery, tangy filling and crumbly texture.
Arrange the bars on a decorative platter or tiered cake stand at brunches, afternoon teas, or dessert tables for an inviting, elegant display. For family gatherings or informal events, stack the bars casually on a tray lined with parchment or lace paper for a cozy, homemade feel.
These bars also make wonderful gifts-place them in a decorative tin or box, separated with wax or parchment paper, for a thoughtful homemade present. Pairing Lemon Crumb Bars with fresh berries, such as raspberries or blueberries, on the side adds a burst of color and balances the sweetness.
For a special occasion, top each bar with a dollop of whipped cream and a sprinkle of extra lemon zest just before serving. Whether served as individual bites at a party or enjoyed with a warm beverage during a quiet afternoon, Lemon Crumb Bars delight guests and homebakers alike.
They are easy to portion, transport well, and retain their delicious flavor and texture for several days when stored properly. If you prefer a more chilled dessert, refrigerate the bars before serving for an extra refreshing treat, especially during the warmer months.
Health Benefits
While Lemon Crumb Bars are considered a decadent treat, they do offer some health benefits, particularly from the fresh lemons used in the recipe. Lemons are rich in vitamin C, one of the most important antioxidants for the body, helping to support immune function and promote healthy skin.
The zest also contains essential oils that can offer mild digestive benefits and add to the overall nutrient content. While this dessert is relatively high in energy (calories) due to the butter and sweetened condensed milk, modifications can be made for those looking to lighten up the recipe.
Opting for reduced-fat butter and condensed milk, or experimenting with whole-wheat flour, can increase the fiber and lower the saturated fat content. Overall, Lemon Crumb Bars are best enjoyed in moderation as part of a balanced diet.
Their joyful tang and cheery color can brighten spirits and encourage creative home baking, providing a psychological health boost through the enjoyment of making and sharing homemade treats.
As with any dessert, portion control is important-savoring a single Lemon Crumb Bar after a meal can satisfy a sweet craving while still incorporating wholesome ingredients.
