How to Make Lemon Crumb Bars

Ingredients

  • 1 ½ cups all-purpose flour
  • ⅔ cup granulated sugar
  • ¼ tsp salt
  • ¾ cup cold unsalted butter, cubed
  • 1 tsp vanilla extract
  • 2 large eggs
  • ¾ cup granulated sugar
  • 2 tbsp all-purpose flour
  • 2 tbsp lemon zest (about 2 lemons)
  • ⅓ cup fresh lemon juice
  • Pinch of salt

Step-by-Step Instructions

  1. Preheat your oven to 350°F (175°C) and line an 8×8-inch baking pan with parchment paper. Let the paper hang over the edges to make it easier to lift the bars out later.

  2. In a mixing bowl, whisk together the flour, sugar, and salt. Cut in the cold butter using a pastry cutter or your fingers until the mixture resembles coarse crumbs. Stir in the vanilla for great flavor.

  3. Press two-thirds of the mixture firmly into the bottom of the prepared pan to form the crust. Save the remaining third for the crumble topping.

  4. Bake the crust for 15 minutes or until it becomes lightly golden. Once done, remove from the oven and let it cool slightly.

  5. In a medium bowl, whisk together the eggs and sugar until smooth. Add in the flour, lemon zest, lemon juice, and a pinch of salt. Whisk until fully combined and the mixture is slightly thickened.

  6. Pour the lemon filling over the warm crust. Sprinkle the reserved crumble mixture evenly over the top.

  7. Bake for 20–23 minutes, or until the filling is set, and the topping is golden brown.

  8. Let the bars cool in the pan for about 30 minutes, then transfer to the fridge to chill for at least 1 hour before slicing.

  9. Once set, lift the bars out using the parchment overhang and cut into squares.

Pro Tips

  • Use Fresh Lemons: Fresh lemon juice and zest significantly enhance the flavor compared to bottled varieties. Fresh ingredients often lead to a more vibrant and aromatic end product.

  • Chill Before Cutting: For cleaner cuts, ensure the bars are fully chilled before slicing. This also helps the filling set properly, giving the perfect texture.

  • Experiment with Zest: Using a mix of lemon and lime zest can add a unique twist. Each citrus element enhances the overall flavor profile, giving it an extra layer of complexity.

  • Don’t Overbake: Keep an eye on the bars toward the end of baking. If overbaked, the lemon filling can become tough and lose that delightful melt-in-your-mouth texture.

  • Substitutions: If you’re out of eggs, unsweetened applesauce or silken tofu can be used as a substitute, though the texture might vary slightly.

  • Make Ahead: These bars can be made a day in advance! They actually taste even better after a night in the fridge as the flavors meld.

How to Serve Lemon Crumb Bars

Presentation is key! To serve your Lemon Crumb Bars, place them on a colorful platter and dust with powdered sugar for a touch of elegance. Pair them with fresh berries or a dollop of whipped cream to elevate the experience.

For drinks, consider pairing with iced tea or lemonade. A light white wine or sparkling water also complements the tartness of the bars well. If you’re serving them at a brunch, they pair beautifully with mimosas!

How to Store Lemon Crumb Bars

Lemon Crumb Bars store well in the fridge for up to a week. Make sure to place them in an airtight container to maintain their freshness. For longer storage, they can be frozen for up to 3 months. Just thaw them in the fridge overnight before serving.

Tips to Make Lemon Crumb Bars

  • Taste the Lemon: Always taste your lemon juice before using it. If it’s too tart, you might adjust the amount of sugar in your filling.

  • Creative Toppings: Consider adding coconut flakes on top of the crumble before baking for added texture and flavor.

  • Lemon Lovers: For an extra lemony kick, add a little extra zest or make a lemon glaze to drizzle on top after baking.

Variations

  • Vegan: Replace the eggs with flax eggs or applesauce and use vegan butter for a plant-based version.

  • Gluten-Free: Swap all-purpose flour for a gluten-free mix; ensure all other ingredients are gluten-free too.

  • Berry Lemon Crumb Bars: Add a layer of fresh berries underneath the lemon filling for a fruity twist.

Nutrition Information

(Serving Size: 1 bar | Calories: 180 | Protein: 2g | Carbs: 26g | Fat: 8g | Fiber: 1g | Sugar: 10g)
These bars are lower in protein and high in carbs and sugars due to the sweet ingredients, making them a treat best enjoyed in moderation alongside a balanced diet.

Storage and Reheating

To reheat leftovers, the microwave is the quickest option. Place a bar on a plate, cover with a damp paper towel, and heat for about 15-20 seconds. For a crispier texture, you can also warm them in the oven at a low temperature for about 5–10 minutes.

Customization Ideas

Adjusting flavors can be really fun! Think about adding poppy seeds for a nice crunch or using different citrus fruits like orange or grapefruit. You could also swap out the topping for a layer of crumbs mixed with nuts or oats for a different texture.

Common Mistakes to Avoid

  • Using Cold Ingredients: Make sure your butter is cold but not frozen, as this helps with the crumble texture.
  • Overmixing the Filling: Whisk just until combined to prevent the filling from becoming tough.
  • Not Letting Them Cool: Don’t rush to cut them before they’ve cooled completely; the texture will significantly improve.
  • Ignoring Nutrition Labels: Depending on dietary needs, always keep an eye on ingredient labels for allergens.
