For the Lemon Cookie Bars:

• Sugar cookie mix: Use your favorite brand. It shouldn't have any add-ins.
• Unsalted butter: Feel free to use salted butter.
• Egg: Make sure it's at room temperature.
• Instant lemon pudding mix: The dry mix has a better, more concentrated flavor.
• Fresh lemon juice: Bottled juice isn't my favorite, but it works too.
• Lemon zest: Adds aroma.

For the Lemon Icing:

• Unsalted butter: Don't use salted butter for the icing if you used it for the cookie bar base.
• Powdered sugar: Granulated sugar doesn't work because it makes the icing grainy.
• Lemon juice and zest: Same as for the cookie bar base.

These tender lemon bar cookies with silky icing are a breeze to whip up! Mix, bake, and frost. That's it.

1. Step 1: In a medium bowl, beat the softened butter and egg together until smooth and creamy.

2. Step 2: Add the sugar cookie mix and stir until fully combined.

3. Step 3: Fold in the dry lemon pudding mix, lemon juice, and lemon zest until evenly incorporated.

4. Step 4: Press the dough evenly into the prepared pan, smoothing the top with a spatula or your fingers. Bake for 20–23 minutes, until the edges are lightly golden and the center is set but still soft. Check at 20 minutes to avoid overbaking. Let the bars cool completely in the pan before frosting.

5. Step 5: To make the buttercream, beat the softened butter until creamy. Gradually add the powdered sugar, then mix in the lemon juice and lemon zest until smooth and fluffy.

6. Step 6: Spread the buttercream evenly over the cooled bars and sprinkle with extra lemon zest. Let the frosting set for 10–15 minutes before slicing into squares.

These frosted lemon cookie bars stay moist and yummy! Here’s how to store them properly so they stay fresh:

Counter

In an airtight container at room temperature for 2–3 days.

Refrigerator

Up to 4 days. Bring to room temperature before serving.

Freezer

This works for the sugar cookie bars without icing. Transfer to a freezer-safe bag and store for up to 3 months. Thaw overnight in the fridge or on the counter for 15-20 minutes. Frost before serving.

These simple tricks and tricks will give you perfect lemon bars every time:

Room temperature ingredients: It makes mixing the dough much easier because everything integrates much more smoothly.

The right baking pan: This recipe is made with a 9×9-inch pan. Using a smaller pan (8×8) will make thicker bars, which may require an extra 1–2 minutes of baking.

Cool completely: If the bars are still even a tiny bit warm, the frosting will melt right off. Wait until they're fully cooled to prevent melting the icing.

Avoid over-baking: The center may look slightly soft when you remove the bars from the oven, but it will firm up as it cools. Avoid overbaking to keep the bars chewy.

Adjust icing consistency: If your buttercream feels too thick, add ½ teaspoon lemon juice or milk at a time to reach a spreadable consistency.
