Ingredients You’ll Need

2 1/2 cups all-purpose flour (300 grams): The foundation for these bars. Be sure to spoon it into your measuring cup for accuracy.
1/2 teaspoon baking powder (2 grams): This will help with the rise, ensuring your bars are soft and chewy.
1/2 teaspoon table salt (9 grams): Enhances the sweetness and balances the flavors.
1 1/2 cups granulated sugar (297 grams): Sweetens the bars beautifully; you could use half brown sugar for a caramel note.
14 tablespoons unsalted butter (197.75 grams, room temperature): Gives the bars their rich, buttery taste. Make sure it’s softened for easy mixing.
2 large eggs: Provides moisture and structure to the bars.
2 teaspoons lemon extract (9.9 ml): Adds that lovely lemon flavor; feel free to use fresh lemon juice if you prefer.
1/2 cup unsalted butter (room temperature, 113 grams): This will be combined with powdered sugar to create the luscious frosting.
5 cups powdered sugar (567.5 grams): Creates a sweet and creamy frosting that pairs perfectly with the bars.
1/4 cup milk (59 ml or 56.75 grams): Adds smoothness to the frosting; any type of milk works, or use a dairy-free alternative.
2 teaspoons lemon extract: Another splash of lemon to brighten up the frosting!
1/8 teaspoon table salt: Just a pinch to balance the sweetness of the frosting.

Preheat Future Goodness: Preheat your oven to 350°F (175°C). Line a 9×13 inch baking pan with parchment paper, letting some hang over the sides — this will help with easy removal later.
Mix Dry Ingredients: In a bowl, whisk together 2 1/2 cups all-purpose flour, 1/2 teaspoon baking powder, and 1/2 teaspoon table salt. Set aside for later.
Cream Butter and Sugar: In a large mixing bowl, beat 14 tablespoons of softened unsalted butter with 1 1/2 cups granulated sugar until fluffy, about 2 minutes. The mixture should be pale and creamy – this step is essential for the right texture.
Add Eggs and Lemon: Incorporate 2 large eggs one at a time, mixing well after each addition. Then, add 2 teaspoons of lemon extract, blending until just combined.
Combine Mixtures: Gradually add the dry ingredients from the bowl to the wet ingredients, mixing until just incorporated. The dough will be soft but manageable, perfect for pressing into the pan.
Spread and Bake: Spread the mixture evenly into your prepared pan and smooth the top with a spatula. Bake in the preheated oven for about 10-12 minutes. The edges should just start to turn golden, while the center remains slightly soft.
Cool Completely: Allow the cookie bars to cool in the pan on a wire rack before frosting. It’s essential they’re cool to prevent the frosting from melting.
Prepare the Frosting: In a clean bowl, beat together 1/2 cup softened unsalted butter, 5 cups powdered sugar, 1/4 cup milk, 2 teaspoons lemon extract, and 1/8 teaspoon salt until creamy and smooth.
Frost and Slice: Once the bars are completely cool, spread the frosting on top generously. Use the parchment to lift the bars out of the pan, slice them into squares, and serve!

Storing & Reheating

Store your lemon sugar cookie bars at room temperature in an airtight container to keep them fresh for up to 3-5 days. If you want to keep them longer, feel free to refrigerate for up to a week. You can also freeze the bars for up to three months; simply wrap them tightly in plastic wrap and then place them in a freezer-safe bag. For best results, thaw them in the fridge overnight before enjoying again. If they lose a bit of their freshness, a few seconds in the microwave can help soften them back to their delightful texture!

Chef’s Helpful Tips

Always use room temperature ingredients for proper incorporation, especially the butter and eggs.
For a zestier flavor, incorporate some fresh lemon zest into the frosting.
If you find your bars are too soft, ensure you bake them just until the edges are golden – overbaking can lead to dry bars.
Make sure to sift the powdered sugar before making the frosting to avoid lumps and ensure a smooth result.
Consider adding a light dusting of additional lemon zest over the frosted top for added visual appeal and flavor.

Baking lemon sugar cookie bars is a joyful experience that results in a delicious, zesty treat perfect for any occasion. You’ll find that the combination of a soft cookie and bright lemon frosting brings a delightful balance that’s hard to resist. Don’t hesitate to experiment with variations; perhaps try adding some poppy seeds for a classic lemon-poppy combination or even some berries on top before frosting. The options are truly endless, and with each batch, you’re bound to find a new favorite twist. I invite you to dive into this adventure of flavors and enjoy!

Recipe FAQs

Can I use fresh lemons instead of lemon extract?

Absolutely! You can substitute lemon extract with fresh lemon juice, but note that it may affect the consistency of the frosting. Use about the same amount of juice, and consider using a bit more powdered sugar to achieve the desired thickness.

How do I know when the bars are done baking?

Keep an eye on the edges; they should turn a light golden brown, while the center should appear slightly soft and not jiggly. A toothpick inserted in the middle should come out clean or with a few moist crumbs attached for the perfect chewy texture.

Can I make these bars ahead of time?

Yes! Lemon sugar cookie bars can be baked a day or two ahead of your planned event. Just be sure to store them in an airtight container to maintain freshness. Frost them just before serving for the best taste and appearance.

What should I do if my frosting is too thin?

If your frosting is too thin, add more powdered sugar, a tablespoon at a time, until you reach your desired thickness. If it’s too thick, you can add a little more milk to loosen it up. Adjusting slowly will help you find the perfect consistency.
