Ingredients

When I bake Lemon Crumb Bars, I gather simple ingredients that work in harmony. The bright lemon, rich butter, and crisp crust come together with minimal fuss.

• 1 cup unsalted butter, melted — adds moisture and flavor to crust and crumb.
• 2 cups all-purpose flour — gives structure and a tender crumb.
• 1 cup granulated sugar — sweetens the bars and helps crisp the topping.
• ½ tsp salt — balances the lemon brightness.
• 1½ tbsp lemon zest — the fragrant punch of citrus in every bite.
• 1 (14 oz) can sweetened condensed milk — makes the filling creamy and glossy.
• ½ cup fresh lemon juice — provides tang and acidity for balance.
• 2 egg yolks — enrich the filling and help it set nicely.
• Powdered sugar, for dusting (optional) — a delicate finish if you like.

Pantry-ready ingredients for Lemon Crumb Bars

Pantry-ready ingredients for Lemon Crumb Bars are simple. Gather butter, flour, sugar, salt, lemons, condensed milk, and eggs. Powdered sugar is optional for dusting. Fresh lemon zest wakes the bars.

Ingredient notes and substitutions for Lemon Crumb Bars

Fresh lemon zest is best for aroma and brightness, but bottled zest can work in a pinch. You can swap lime zest for a similar tang, or add 1/4 teaspoon vanilla to warm the lemon notes.

How to Make Lemon Crumb Bars

Step 1: Prep and crust formation

Preheat the oven to 350°F. Line an 8×8-inch pan with parchment, leaving overhang for easy lifting. In a large bowl, mix melted butter, flour, sugar, salt, and lemon zest until crumbly. Press two-thirds of this mixture into the pan to form the crust. Save the rest for the topping to keep this Lemon Crumb Bars lively.

Step 2: Make the lemon filling

Whisk together sweetened condensed milk, fresh lemon juice, and egg yolks until smooth and glossy. Stir in the zest if you love extra brightness. I like to mix by hand first, then finish with a whisk to avoid lumps. Pour this sunny filling over the crust, spreading evenly so every bite shines for Lemon Crumb Bars. Let it settle for a minute while you fold the topping.

Step 3: Layer filling and top with crumb

Sprinkle the remaining crumb over the lemon filling, then press lightly to form a cohesive top. The crumb should be a bit loose, not packed, so the bars stay crumbly. I tap the pan on the counter once to level the surface, then give the top a final crumble for texture. This contrast keeps every bite interesting.

Step 4: Bake until set and lightly golden

Bake for 25–30 minutes, or until the top is lightly golden and the center is just set. The filling should look glossy, not jiggly. If you see dark edges too fast, tent with foil for the last minutes. Let the bars cool on a rack; this helps them finish setting. If your oven runs hot, lower to 325°F and watch closely.

Step 5: Chill, slice, and dust

Chill the Lemon Crumb Bars in the pan for at least an hour. Use the parchment overhang to lift them out, then slice into neat squares. Dust with powdered sugar if desired. Serving cold makes the lemon flavor pop and the crumb stay crisp. For cleaner slices, wipe the knife between cuts.

Tips for Success

• Tip: measure accurately for a tender crust (Lemon Crumb Bars)

  Weigh flour if you can. Too much flour dries crust. Scoop, then level for tender bars. Always tare the scale.

• Tip: zest and juice for brightness (Lemon Crumb Bars)

  Use fresh lemons. Zest before juicing. Fresh zest brightens every bite. Rinse your lemons well. This adds a sunny brightness.

• Tip: don’t overmix the crumble topping (Lemon Crumb Bars)

  Mix until the crumb resembles wet sand. Don’t overwork it. A few coarse crumbs stay crisp. Chill the topping briefly if your kitchen is warm.
