Ingredients
Sugar Cookie Base:
- 2 cups all-purpose flour
- 1/2 cup granulated sugar
- 1/4 cup powdered sugar
- 1/2 teaspoon salt
- 1 cup cold unsalted butter, cubed
- 1 large egg yolk
- 1 teaspoon vanilla extract
Lemonade Layer:
- 4 large eggs
- 1 1/2 cups granulated sugar
- 1/4 cup all-purpose flour
- 1/2 cup fresh lemon juice
- 2 tablespoons lemon zest
- 1/4 teaspoon salt
- 3 tablespoons butter, melted
Crumble Topping:
- 1 cup all-purpose flour
- 1/2 cup brown sugar
- 1/4 cup granulated sugar
- 1/2 cup cold butter, cubed
- Pinch of salt
Step-by-Step Instructions
Prepare the Base:
- Preheat oven to 350°F and line a 9×13 inch pan with parchment paper.
- Combine flour, both sugars, and salt in a bowl. Cut in cold butter until mixture resembles coarse crumbs.
- Mix in egg yolk and vanilla until dough comes together.
- Press firmly into prepared pan and bake for 18-20 minutes until lightly golden.
Make the Lemonade Layer:
- Whisk eggs and sugar until smooth. Add flour, lemon juice, zest, and salt.
- Stir in melted butter until completely combined.
- Pour over warm cookie base.
Add the Crumble:
- Mix flour, both sugars, and salt. Cut in cold butter until crumbly.
- Sprinkle evenly over lemonade layer.
- Bake 25-30 minutes until crumble is golden and filling is set.
- Cool completely before cutting.
Things to Remember
Always use fresh lemon juice for the best flavor – bottled juice simply can’t compare. Make sure your cookie base is still warm when you add the lemonade layer, as this helps create better adhesion between layers. Don’t overbake the final product; the lemonade layer should be set but still slightly jiggly in the center when you remove it from the oven. It will continue cooking as it cools and firm up perfectly.
What to Serve With Them
These sugar cookie lemonade bars are delicious on their own, but they pair beautifully with vanilla bean ice cream or fresh whipped cream. For an elegant presentation, dust with powdered sugar just before serving. They’re perfect alongside iced tea, coffee, or sparkling water with mint. Consider serving them at summer barbecues, baby showers, or afternoon tea parties.
Mix It Up
Try lime juice and zest instead of lemon for a different citrus twist. Add fresh berries to the lemonade layer for extra flavor and color. For chocolate lovers, drizzle melted white chocolate over the cooled bars. You can also experiment with different extracts in the cookie base – almond extract pairs particularly well with lemon flavors.
Keeping Them Fresh
Store covered at room temperature for up to three days, or refrigerate for up to one week. These bars actually taste even better after a day, as the flavors have time to meld together. For longer storage, wrap individual bars in plastic wrap and freeze for up to three months. Thaw at room temperature before serving.
Kitchen Tips
Use a light-colored metal pan for even baking – dark pans can cause the bottom to overcook. Line your pan with parchment paper extending up the sides for easy removal. When cutting, use a sharp knife wiped clean between cuts for neat squares. If the crumble topping browns too quickly, tent with foil during the last few minutes of baking.
Frequently Asked Questions
Can I make these ahead of time? Absolutely! These sugar cookie lemonade bars are perfect make-ahead desserts and often taste better the next day.
What if I don’t have fresh lemons? While fresh is best, you can substitute with 1/2 cup bottled lemon juice, though the flavor won’t be quite as bright.
Can I double the recipe? Yes, but you’ll need to use two 9×13 pans or one large sheet pan and adjust baking time accordingly.
Why is my lemonade layer too tart? Taste your lemon juice before using – some lemons are more acidic than others. You can add an extra tablespoon of sugar if needed.
Can I use salted butter? Yes, just reduce the added salt in each component by half.
