Homemade Key Lime Cookies Recipe

Ingredients

188 g (1 ½ cups) all-purpose flour (plain flour)
½ teaspoon baking powder
¼ teaspoon baking soda
¼ teaspoon sea salt
3 tablespoons lime zest, freshly grated (approx 3 regular limes or 6 key limes)
250 g (1 ¼ cups) granulated sugar (use organic if in the US)
130 g (⅗ cups) vegan butter, room temperature
40 g (2 tbsp) Greek-style vegan yogurt, or regular unsweetened soy or coconut yogurt
4 teaspoons lime juice, freshly squeezed

Ingredient Substitutions

For those with dietary restrictions or just looking to experiment with different flavors, here are some handy substitutions for the key components of the Key Lime Cookies Recipe:

Flour: To make gluten-free Key Lime Cookies, substitute the all-purpose flour with your favorite gluten-free blend. Ensure it's a 1:1 baking blend for the best results. If the blend doesn’t contain xanthan gum, you might need to add it separately according to the blend’s recommendation.
Butter: For a dairy-free or vegan alternative, use the same amount of a plant-based margarine or coconut oil. Keep an eye on the texture, as coconut oil may make the dough slightly oilier.
Sugar: If you prefer a less refined sugar, coconut sugar is a great option. Just note that it can alter the color of the cookies to a darker shade.
Eggs: For those avoiding eggs, a flaxseed or chia seed egg works wonderfully. Mix 1 tablespoon of ground flaxseed or chia seeds with 3 tablespoons of water, let it sit for 15 minutes, and use it to replace one egg.
Key Lime Juice: If you can’t find key limes, regular lime juice works just as well. For a different citrus twist, try using lemon or orange zest and juice.

Instructions

Prepare: Preheat your oven to 175°C (350°F). Line 2 baking trays or cookie sheets with parchment paper.
Blend Dry Ingredients: In a mixing bowl, whisk together the flour, baking soda, baking powder, and salt.
Flavor the Sugar: In a separate large mixing bowl, add the sugar and lime zest. Rub the zest into the sugar with your fingertips. Save 50g (¼ cup) of this lime sugar mix in a small bowl for later.
Combine Wet Ingredients: Add the vegan butter to the large mixing bowl with the lime sugar (minus the 50g you set aside) and cream together using an electric mixer until light and airy, approximately 2-3 minutes. Then mix in the vegan yogurt and lime juice until combined.
Combine Dry and Wet Ingredients: Fold in the flour mixture with a spatula.
Chill the Dough: Cover and refrigerate for at least 15 minutes.
Shape the Cookies: Roll the dough into 12 balls, about 50g each. Roll each ball in the reserved lime sugar and place them on the prepared cookie sheets, spaced at least 2 inches apart.
Bake: Bake for 10 minutes. Then remove them and immediately use a large cookie cutter to round off the edges if you desire a perfectly round shape. This step ensures the cookies don't end up too flat.
Cool: Allow the cookies to cool on the baking tray for about 5 minutes.

Optional Variations

Key Lime Pie Cookies: Decorate cooled cookies with Swiss Meringue Buttercream, crushed graham crackers, and extra lime zest.
Coconut Lime Cookies: Add shredded coconut into the cookie dough for a tropical twist.
Ice Cream Sandwiches: Place a scoop of vegan vanilla, strawberry, passionfruit, or mango ice cream between two cooled cookies.

Serving Suggestions

Key Lime Cookies are versatile and can complement a wide range of occasions and pairings. Here are some serving suggestions to elevate your cookie experience:

With Tea or Coffee: These cookies are perfect with a cup of Earl Grey tea or a freshly brewed coffee. The citrus tang beautifully cuts through the bitterness of these beverages.
Dessert Platters: Arrange the cookies on a platter with a selection of fresh berries, whipped cream, and other citrus desserts for a refreshing end to any meal.
Ice Cream Sandwiches: For a summer treat, use these cookies to sandwich a scoop of vanilla or coconut ice cream. The combination of creamy and tangy is irresistible.

Storage

Store these cookies at room temperature for up to 5-6 days in a sealed airtight container.

Storage and Freezing Instructions

To ensure your Key Lime Cookies stay delicious, follow these storage and freezing tips:

Storing: Once completely cooled, store the cookies in an airtight container at room temperature. They will last for up to 1 week. To keep them fresher longer, you can place a piece of bread in the container; the cookies will absorb moisture from the bread, staying soft and chewy.
Freezing Raw Dough: Portion the dough and freeze it on a baking sheet before transferring to a ziplock bag. It can be stored for up to 3 months. Bake from frozen, adding a minute or two to the baking time.
Freezing Baked Cookies: Ensure the cookies are completely cooled before freezing. Place them in a single layer on a baking sheet to freeze, then stack them with parchment paper in between layers in an airtight container. They can be frozen for up to 3 months. Thaw at room temperature before serving.
