How to Make Lemon Crumb Bars
Step 1: Preheat Your Oven
Preheat your oven to 350°F (175°C). This step is crucial as it ensures your bars bake evenly. While it’s warming up, grab a large bowl to mix your crust ingredients!
Step 2: Prepare the Crust
In your bowl, combine flour, sugar, baking powder, melted butter, and salt until the mixture is crumbly. Remember to reserve 1/2 cup of this mixture for topping later! Press the rest firmly into the bottom of an 8×8-inch baking pan lined with parchment paper. Bake this delicious base for about 12-15 minutes until it turns lightly golden. This step creates a solid foundation for our creamy filling.
Step 3: Whisk Together the Filling
In another bowl, whisk together eggs, sugar, flour, lemon juice, and lemon zest until smooth. It’s important to mix well so that every bite has that lovely zesty flavor we’re after! Once combined, pour this bright mixture evenly over your baked crust.
Step 4: Add the Crumble Topping
Sprinkle your reserved crumb mixture on top of the lemon filling. This will give us that delightful texture we love in Lemon Crumb Bars! Now it’s time to bake again—pop it back into the oven for an additional 20-25 minutes or until you see the filling set and the top lightly golden.
Step 5: Cool and Serve
Once baked, let your bars cool completely at room temperature before chilling them in the refrigerator for at least one hour. This waiting period helps them firm up nicely! When you’re ready to serve, slice them into squares and dust with powdered sugar if desired. Enjoy every bite of these refreshing Lemon Crumb Bars!
Pro Tips for Making Lemon Crumb Bars
Making lemon crumb bars is a joyful experience, and with a few simple tips, you can ensure they turn out perfectly every time!
- Use fresh lemon juice: Freshly squeezed lemon juice will give your bars a vibrant, tangy flavor that bottled juice just can’t match.
- Let them cool completely: Allowing the bars to cool thoroughly before slicing helps the filling set properly, making for cleaner cuts and better presentation.
- Chill for extra firmness: Chilling the bars in the refrigerator for at least an hour after baking firms them up nicely, enhancing their texture.
- Dust with powdered sugar just before serving: Adding powdered sugar right before serving prevents it from soaking into the bars and keeps that lovely aesthetic intact.

Serving lemon crumb bars can be as delightful as making them! They’re perfect for gatherings, picnics, or just enjoying at home. Here are some fun ways to present this zesty treat.
