How to Make Lemon Sugar Cookie Bars
- Preheat the Oven: Start by preheating your oven to 350°F (175°C). This step ensures even baking for your delicious bars.
- Prepare the Baking Dish: Grease a 9×13-inch baking dish or line it with parchment paper for easy removal.
- Mix the Dry Ingredients: In a bowl, whisk together 2 1/2 cups all-purpose flour, 1/2 teaspoon baking powder, and 1/2 teaspoon salt. Set this mixture aside.
- Cream the Sugar and Butter: In a large mixing bowl, beat 14 tablespoons of unsalted butter with 1 1/2 cups granulated sugar until light and fluffy, about 3-4 minutes.
- Add the Eggs and Extract: Beat in the 2 large eggs, one at a time, followed by 2 teaspoons of lemon extract. This will create a smooth, creamy batter.
- Combine Dry and Wet Ingredients: Slowly mix the dry ingredients into the wet mixture until just combined. Be careful not to over-mix.
- Spread the Batter: Pour the cookie batter into the prepared baking dish, spreading it evenly with a spatula.
- Bake: Bake in the preheated oven for about 10-12 minutes, or until the edges are lightly golden. A toothpick should come out clean from the center.
- Cool Down: Once baked, allow the cookie bars to cool in the pan for about 10 minutes, then transfer to a wire rack to cool completely.
- Prepare the Frosting: In a mixing bowl, beat 1/2 cup of unsalted butter until smooth. Gradually add in 5 cups of powdered sugar, 1/4 cup of milk, 2 teaspoons of lemon extract, and 1/8 teaspoon salt until smooth and creamy.
- Frost the Bars: Once the cookie bars are completely cooled, spread the lemon frosting evenly on top with a spatula.
- Slice and Serve: Cut into 24 squares and enjoy! They are perfect for entertaining or just treating yourself.
Storing & Reheating
To store your Lemon Sugar Cookie Bars, keep them in an airtight container at room temperature for up to 3 days. If you need longer storage, pop them in the refrigerator, where they can last up to a week. For longer preservation, freeze them, layered with parchment paper, in a freezer-safe container for up to 3 months. When you’re ready to enjoy, simply thaw at room temperature. If you want to revive the frosting’s texture after refrigeration, a quick 5-second zap in the microwave can freshen them up nicely!
Chef’s Helpful Tips
- Be sure your butter is at room temperature for the best creaming results. Cold butter can lead to dense bars.
- Avoid overbaking! Check the bars for doneness a minute or two before the timer goes off; they will firm as they cool.
- If you want an extra zing, add the zest of one lemon to the batter and frosting for an amplified lemon flavor.
- For a fun twist, consider sprinkling crushed lemon candies or lemon zest on top of the frosting before slicing.
- You can easily scale the recipe by doubling it for larger events or using smaller pans for thicker cookies.
Lemon Sugar Cookie Bars not only capture the essence of sweet and tart but also the warmth of home-baked goodness. This recipe yields soft, chewy bars that are sure to satisfy any craving. Plus, with the creamy frosting drizzled on top, they make for an eye-catching treat that dares to stand out on a dessert table.
Experiment with the recipe, perhaps add a little extra zest or even try a different frosting flavor—maybe a raspberry or vanilla would be delightful! Whatever you choose, I invite you to share these tasty bars with friends, family, and anyone you want to impress. Bake them with love, savor each bite, and enjoy every moment of joy they bring to your day!

Recipe FAQs

Absolutely! You can use the juice and zest of fresh lemons in place of lemon extract. For this recipe, about 1/4 cup of fresh lemon juice and zest from one lemon should work beautifully.
