Step-by-Step Instructions for Making Lemon Crunch Bars

Step 1: Preheat and Prepare Pan

Preheat your oven to 350°F (175°C). Line an 8×8-inch baking dish with parchment paper, allowing some overhang for easy removal.

Step 2: Make the Crumb Mixture

In a medium bowl, stir together the melted butter, sugar, flour, salt, and pecans (if using). Mix until the mixture resembles coarse crumbs.

Step 3: Press the Crust

Press two-thirds of the crumb mixture firmly into the bottom of the prepared pan to form the crust. Bake for 10–12 minutes or until lightly golden.

Step 4: Prepare the Lemon Filling

In a separate bowl, whisk together sweetened condensed milk, lemon juice, zest, egg yolks, and vanilla until smooth and creamy.

Step 5: Assemble the Layers

Pour the lemon mixture over the pre-baked crust and spread evenly. Crumble the remaining crust mixture evenly over the top.

Step 6: Bake Again

Return to the oven and bake for another 20–22 minutes, or until the top is lightly golden and the center is just set.

Step 7: Cool and Chill

Let the bars cool completely at room temperature, then chill in the refrigerator for at least 2 hours before cutting.

Step 8: Slice and Serve

Once chilled, lift bars out using the parchment and cut into squares. Dust with powdered sugar if desired.

Pair these with a refreshing drink like Strawberry Cream Soda for a delightful afternoon treat.

Tips for the Best Lemon Crumb Bars Every Time

  • Use fresh lemon juice for the best flavor—bottled lemon juice just isn’t the same.
  • Don’t skip chilling before slicing, or the filling may ooze.
  • Press crust firmly to avoid crumbling when cutting.
  • Double the recipe for larger crowds using a 9×13-inch pan.

Lemon Bars with Pecan Crust FAQs

Can I make these without pecans?
Absolutely! Simply omit them, or substitute with walnuts or almonds if preferred.

Can I use graham cracker crumbs as the crust?
You can, but you’ll lose the buttery crumble texture that makes these unique.

Do they need to be refrigerated?
Yes. Because of the dairy in the filling, they should be stored chilled.

Can I make them gluten-free?
Yes—use a 1-to-1 gluten-free flour blend and ensure your oats or add-ins are certified gluten-free.

Can I freeze lemon bars?
Definitely. They freeze beautifully and taste just as fresh when thawed.
