For the Crust and Topping
- 1 1/2 cups all-purpose flour
- 1/2 cup granulated sugar
- 1/2 teaspoon baking powder
- 1/2 cup unsalted butter, melted
- 1/4 teaspoon salt
For the Lemon Filling
- 2 large eggs
- 1 cup granulated sugar
- 1/4 cup all-purpose flour
- 1/3 cup fresh lemon juice
- 1 tablespoon lemon zest
How to Make Lemon Crumb Bars
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). In a large bowl, mix together the flour, sugar, baking powder, melted butter, and salt until you achieve a crumbly texture. Reserve 1/2 cup of this mixture for later use.
Step 2: Prepare the Crust
Press the remaining mixture into the bottom of an 8×8-inch baking pan lined with parchment paper. Bake this layer in the preheated oven for about 12-15 minutes or until it turns lightly golden.
Step 3: Make the Lemon Filling
In another bowl, whisk together the eggs, sugar, flour, lemon juice, and lemon zest until smooth.
Step 4: Assemble the Bars
Pour the lemon mixture evenly over your baked crust. Sprinkle the reserved crumb mixture on top of this layer.
Step 5: Bake Again
Return the pan to the oven and bake for an additional 20-25 minutes or until you see that the filling has set and the top is lightly golden.
Step 6: Cool and Serve
Allow your bars to cool completely at room temperature. Once cooled, chill them in the refrigerator for at least one hour. Slice into squares and dust with powdered sugar before serving. Enjoy your zesty Lemon Crumb Bars!

With Fresh Berries
- Serve the bars with a side of fresh strawberries, blueberries, or raspberries for a burst of flavor and color.
With Whipped Cream
- Top the lemon crumb bars with a dollop of whipped cream for added richness and creaminess that complements the tangy filling.

How to Perfect Lemon Crumb Bars
Perfecting your lemon crumb bars is all about attention to detail. Here are some tips to ensure they turn out delicious every time.
- Use Fresh Lemons: For the best flavor, always use fresh lemon juice and zest instead of bottled versions.
- Measure Accurately: Make sure to measure your ingredients precisely for consistent results in texture and taste.
- Chill Before Serving: Allowing the bars to chill in the refrigerator helps them set properly and enhances their flavor.
- Don’t Overbake: Keep an eye on the baking time; overbaking can lead to a dry filling. The edges should be lightly golden while the center is set but still slightly jiggly.
- Let Them Cool Completely: Letting the bars cool completely ensures they slice neatly without falling apart.
Best Side Dishes for Lemon Crumb Bars
When serving lemon crumb bars, pairing them with complementary dishes can elevate your dessert experience. Here are some great side dish ideas:
- Vanilla Ice Cream: A scoop of creamy vanilla ice cream brings a delightful contrast to the tangy lemon flavor.
- Fruit Salad: A refreshing fruit salad adds variety and balances out sweetness with natural flavors.
- Cheese Platter: A selection of mild cheeses pairs well, offering a savory counterpoint to the sweet dessert.
- Coconut Macaroons: These chewy treats add texture and a hint of tropical flavor that works wonderfully with lemon.
- Chocolate Dipped Strawberries: The rich chocolate enhances the citrus notes while adding visual appeal.
- Almond Biscotti: Crunchy almond biscotti makes for a perfect crunchy side, ideal for dipping into coffee or tea alongside your dessert.
Common Mistakes to Avoid
When making Lemon Crumb Bars, it’s easy to overlook some key details. Here are common mistakes to avoid for the best results.
- Bold crust preparation: Not pressing the crust firmly enough can lead to a crumbly base. Make sure to press it down evenly for better structure.
- Bold egg mixing: Failing to mix the eggs thoroughly can result in an uneven filling. Whisk until smooth for a creamy consistency.
- Bold baking time: Overbaking or underbaking can ruin your bars. Keep an eye on them and use a toothpick to check for doneness.
- Bold cooling period: Cutting into warm bars can make them fall apart. Allow them to cool completely, then chill before slicing.
- Bold lemon zest: Skipping lemon zest will reduce flavor depth. Always include it for that extra zing in your bars.
