How to Make Lemon Crumb Bars

Step 1: Preheat the Oven

Set your oven to 350°F (175°C). Line a 9×9-inch baking pan with parchment paper for easy removal later.

Step 2: Make the Crust

In a large bowl:
1. Mix together the all-purpose flour, granulated sugar, brown sugar, salt, and baking powder.
2. Pour in the melted butter and stir until the mixture becomes crumbly.
3. Press about ⅔ of this mixture evenly into the prepared pan.
4. Bake for 15 minutes or until lightly golden.

Step 3: Prepare the Lemon Filling

In another large bowl:
1. Whisk together the sweetened condensed milk, egg yolks, heavy cream, and salt.
2. Gradually whisk in the fresh lemon juice, mixing until smooth.

Step 4: Assemble and Bake

1. Pour the lemon filling over the hot crust you’ve just baked.
2. Sprinkle the remaining crumb mixture evenly on top of the filling.
3. Bake for an additional 15-20 minutes until the top is golden brown and filling is set.

Step 5: Cool and Chill

Allow your bars to cool completely at room temperature before refrigerating them for at least 4 hours. This step is crucial for achieving clean slices!

How to Serve Lemon Crumb Bars

Lemon crumb bars are a delightful treat that can be served in various ways to enhance their tangy and sweet flavor. Whether you are hosting a gathering or enjoying them at home, these serving suggestions will elevate your dessert experience.

With Fresh Berries

• Raspberry or Blueberry Pairing: Serve alongside a handful of fresh raspberries or blueberries for a burst of color and freshness.
• Berry Compote: Drizzle with a homemade berry compote for added sweetness and tartness.

Topped with Cream

• Whipped Cream: A dollop of whipped cream on top adds a light and airy texture that complements the lemon filling.
• Mascarpone Cheese: Spread some mascarpone cheese over each bar for a rich and creamy contrast to the tanginess.

Garnished with Mint

• Fresh Mint Leaves: Adding mint leaves not only enhances presentation but also provides a refreshing flavor that balances the lemon.
• Mint Infused Sugar: Sprinkle some mint-infused sugar over the top for an aromatic twist.

How to Perfect Lemon Crumb Bars

To achieve the perfect lemon crumb bars, follow these helpful tips. They will guide you through each step for optimal results.

• Use Fresh Lemons: Fresh lemon juice gives a bright flavor compared to bottled juice. It makes all the difference in taste!
• Chill Before Cutting: Allow the bars to chill in the refrigerator for at least 4 hours. This helps them set properly, making slicing easier.
• Avoid Overmixing: When preparing the lemon filling, mix just until combined. Overmixing can lead to a less creamy texture.
• Preheat Your Oven Thoroughly: Ensure your oven is fully preheated before baking. This helps achieve an even bake and golden crust.
• Line Your Pan Well: Use parchment paper to line your baking pan. This makes removing the bars much easier without crumbling them.
• Dust with Powdered Sugar Right Before Serving: For an elegant touch, dust powdered sugar just before serving. It adds sweetness and enhances presentation.

Common Mistakes to Avoid

Avoiding common mistakes can make your Lemon Crumb Bars turn out perfectly every time. Here are some tips to ensure success.

• Skipping the Cooling Time: Allowing your bars to cool completely before slicing is crucial. If you cut them too soon, they may crumble and lose their shape.
• Not Measuring Ingredients Accurately: Baking is a science, so be precise with your measurements. Use a kitchen scale or measuring cups for accuracy to achieve the right texture and flavor.
• Overmixing the Filling: When combining the lemon filling ingredients, mix just until smooth. Overmixing can incorporate air, which may affect the texture of your bars.
• Using Bottled Lemon Juice: Fresh lemon juice makes a significant difference in flavor. Always opt for fresh lemons for that vibrant, tangy taste in your Lemon Crumb Bars.
• Neglecting to Preheat the Oven: Preheating ensures even cooking. Always set your oven to 350°F (175°C) before starting to bake for best results.

Refrigerator Storage

• Store leftover Lemon Crumb Bars in an airtight container.
• They will stay fresh for up to 5 days.
• Make sure they are completely cooled before sealing them in the container.

Freezing Lemon Crumb Bars

• For longer storage, freeze your bars in an airtight container.
• They can last up to 3 months in the freezer.
• Thaw them in the refrigerator before serving for optimal texture.

Reheating Lemon Crumb Bars

• Oven: Preheat your oven to 300°F (150°C) and warm the bars for about 10-15 minutes for a freshly baked taste.
• Microwave: Heat individual portions on medium power for about 20-30 seconds until warmed through.
