Ingredients in Lemon Crumb Bars
Let’s talk about what goes into these beauties—just a few pantry staples, but they create something truly magical. Here’s what you’ll need:
Butter: The base for both the crumb and filling. It gives the bars that irresistible richness and melt-in-your-mouth texture.
Sugar: Adds sweetness to balance the tartness of the lemon and helps form that delightful crumb topping.
Flour: The backbone of the crumb and crust, creating a light and tender texture. It’s the perfect structure for the lemony filling.
Lemon Zest: This is where the magic happens—this bright, citrusy flavor shines through in every bite.
Lemon Juice: The tangy star of the show, giving these bars that fresh and zesty kick.
Eggs: They help bind the filling together, giving it a creamy and smooth consistency.
Baking Powder: A little leavening agent to make the filling just the right amount of fluffy.

Instructions
Let’s dive into the simple steps that will have these Lemon Crumb Bars in your oven in no time:
Preheat the Oven: Start by preheating your oven to 350°F. This ensures that everything bakes evenly, and your crust will have that perfect golden crunch.
Make the Crumb Mixture: In a large bowl, combine flour, sugar, and melted butter. Mix until you get a crumbly texture. This will form the base and crumb topping for your bars.
Press the Crust: Press a little more than half of the crumb mixture into the bottom of a greased baking pan. This forms your crust, and it should be compact but not overly pressed—just enough to hold together.
Prepare the Lemon Filling: In another bowl, whisk together eggs, sugar, lemon juice, lemon zest, flour, and baking powder until smooth and creamy. This is the luscious filling that will sit perfectly atop your crust.
Assemble the Bars: Pour the lemon filling over the crust in the pan. Then sprinkle the remaining crumb mixture over the top. This creates that perfect balance of buttery crumb topping and creamy lemon filling.
Bake to Perfection: Bake the bars for about 30 minutes or until they’re golden and set in the middle. You’ll know they’re done when the edges are lightly browned, and the top is firm.
Let Cool and Slice: Allow the bars to cool completely before cutting them into squares. This helps them set and makes them easier to slice without falling apart.
Serve and Enjoy: Once they’ve cooled and you’ve sliced them up, dig in and enjoy! These bars are perfect for any occasion and always disappear in a flash.
How to Serve Lemon Crumb Bars
These bars are fantastic on their own, but if you want to take them up a notch, here are a few serving suggestions:
Fresh Berries: A handful of fresh berries on the side adds a pop of color and a burst of freshness that complements the tart lemon.
Whipped Cream: A dollop of whipped cream or even a scoop of vanilla ice cream makes these bars extra indulgent.
Iced Tea: Serve these bars with a glass of chilled iced tea for the ultimate refreshment. Lemonade also pairs perfectly with the citrusy notes of the bars.
Additional Tips
Here are a few more tips to help you make the most of this recipe:
Prep Ahead: You can make the crumb mixture and even the lemon filling ahead of time. Just keep them in the fridge until you’re ready to assemble and bake.
Customize the Flavor: Add a pinch of ginger or cardamom for a warm, spiced kick that pairs wonderfully with the lemon.
Storage Tips: Store these bars in an airtight container at room temperature for up to 3 days, or refrigerate them for longer freshness.
