Ingredients
Instructions
- Preheat oven to 350°F (175°C).
- Combine butter or margarine, confectioners sugar, 2 cups of flour, and salt in a bowl.
- Mix with a pastry blender or two knives until well blended.
- Pat the mixture evenly into a 15 x 10 x 1-inch jelly roll pan.
- Bake for 20 minutes.
- Beat eggs lightly in a separate bowl.
- Stir in granulated sugar, 6 tablespoons of flour, lime juice, and lime or lemon rind.
- Spread the lime mixture over the baked crust.
- Bake for an additional 25 minutes.
- Remove from oven and sift confectioners sugar over the top.
- Let cool and cut into squares.
Tips & Substitutions
For a richer flavor, consider using unsalted butter instead of margarine. If you prefer a sweeter treat, increase the confectioners' sugar slightly. You can substitute key lime juice with regular lime juice if necessary, though the flavor will be less intense. Ensure the crust is evenly patted down to avoid uneven baking, similar to the technique used in Apple Butter Cookies.
Serving Suggestions
These Key Lime Squares are delightful on their own but pair beautifully with a dollop of whipped cream or a scoop of vanilla ice cream for added creaminess. For a refreshing contrast, serve alongside fresh berries or a light fruit salad. They make a fantastic dessert for summer gatherings or as a sweet treat after a meal.
Storage & Reheating
Store any leftover Key Lime Squares in an airtight container in the refrigerator for up to a week. To enjoy them chilled, simply cut them into squares and serve straight from the fridge. If you prefer them at room temperature, let them sit out for about 15 minutes before serving.

Frequently Asked Questions
Can I make this recipe ahead of time?
Absolutely! Key Lime Squares can be made a day or two in advance. Just be sure to store them in the refrigerator to maintain their freshness. Sifting confectioners' sugar on top just before serving will keep them looking their best.
What can I use instead of eggs?
If you're looking for an egg substitute, you can use flax eggs or applesauce. For each egg, mix 1 tablespoon of ground flaxseed with 2.5 tablespoons of water and let it sit until it thickens. Alternatively, 1/4 cup of applesauce can replace one egg, though it may slightly alter the texture.
Can I freeze Key Lime Squares?
Yes, you can freeze Key Lime Squares! Make sure to wrap them well in plastic wrap and then in aluminum foil to avoid freezer burn. They can be stored in the freezer for up to three months. Thaw them in the refrigerator overnight before serving.
