Ingredients

  • 2 1/2 cups flour, divided
  • 1/2 cup powdered sugar
  • 3/4 cup cold butter or margarine
  • 4 eggs
  • 2 cups sugar
  • 1/3 cup lime juice
  • 1/2 teaspoon lime peel
  • 1/2 teaspoon baking powder
  • additional powdered sugar

Instructions

  1. In a bowl, combine 2 cups of flour and powdered sugar.
  2. Cut in the cold butter until the mixture resembles coarse crumbs.
  3. Pat the mixture into a greased 9 x 13 inch pan.
  4. Bake at 350°F for 20 minutes or until lightly browned.
  5. In a separate bowl, beat the eggs.
  6. Add sugar, lime juice, lime peel, and baking powder to the eggs and mix well.

Tips & Substitutions

For a richer flavor, consider adding a tablespoon of lime zest along with the lime juice. If you're short on lime juice, lemon juice can be used as a substitute, although it will slightly alter the taste. Make sure to let the bars cool completely before cutting them to ensure clean edges. To make the crust extra flaky, try using cold coconut oil instead of butter.

Serving Suggestions

These Lime Cooler Bars are best served chilled and dusted with additional powdered sugar for a touch of sweetness. They pair wonderfully with a scoop of vanilla ice cream or a dollop of whipped cream. For a refreshing drink, serve alongside iced tea or lemonade to complement the citrus flavors. They also make a delightful addition to summer picnics or potlucks.

Store leftover Lime Cooler Bars in an airtight container in the refrigerator for up to a week. They can also be frozen; wrap them tightly in plastic wrap and place them in a freezer-safe container.

Frequently Asked Questions

Can I use fresh limes instead of bottled lime juice?

Absolutely! Fresh lime juice will enhance the flavor of your bars. Just be sure to strain it to remove any seeds or pulp. You can also use the zest from the limes to add more zing to the filling.

How do I know when the bars are done baking?

The bars are done when the edges are lightly golden and the center is set but still slightly jiggles when shaken. An inserted toothpick should come out clean or with just a few moist crumbs attached.

Can I make these bars gluten-free?

Yes, you can substitute the all-purpose flour with a gluten-free flour blend. Make sure it contains xanthan gum for the best texture. The baking time may vary slightly, so keep an eye on them while baking.
