Ingredients
For the Cookies















For the Custard Filling






Instructions
Step 1
In a mixing bowl, cream together the softened unsalted butter and granulated sugar until the mixture is fluffy and light in color. This will take about 3 to 4 minutes.
Add in the egg, lime zest, juice, and vanilla extract. Mix until well incorporated.
In another bowl, whisk together the all-purpose flour, baking powder, and salt. Gradually add this dry mixture to the wet ingredients, mixing until a dough forms. Wrap it in plastic wrap and refrigerate for at least 30 minutes.
Step 2
In a saucepan, whisk together the milk, egg yolks, granulated sugar, cornstarch, and lime zest. Place the saucepan over medium heat.
Continuously whisk the mixture until it begins to thicken and bubble. Once thickened, remove it from the heat and stir in the vanilla extract and butter for a smooth texture.
Transfer the custard to a bowl, cover with film to avoid a skin forming, and let it cool completely.
Step 3
Preheat your oven to 180 degrees Celsius (350 degrees Fahrenheit). Line a baking sheet with parchment paper.
Take the chilled dough and scoop out small portions, rolling them into balls. Place the balls on the prepared baking sheet, leaving enough space between them as they will spread while baking.
Using your thumb, make an indentation in the center of each dough ball. Spoon the cooled custard filling into the indents generously.
Step 4
Bake the cookies in the preheated oven for 12 to 15 minutes, or until the edges are lightly golden.
Remove the baking sheet from the oven and allow the cookies to cool on the sheet for a few minutes before transferring them to a wire rack to cool completely.
Enjoy these delightful cookies with a cup of coffee or tea, savoring the balanced flavors of lime and vanilla, perfect for any occasion!
Servings

Equipment
An essential tool for leveling up your baking. Ensure it’s lined with parchment paper to avoid sticking and get that perfect crunch!



Having various sizes makes it easier to mix ingredients without spilling. A glass bowl is great for checking consistency as it allows you to see the mixture clearly.
A sturdy whisk will help you achieve light, fluffy dough. Opt for a silicone spatula to fold and scrape down the sides for thorough mixing!
Precision is key! Use these for accurate ingredient measuring to achieve the perfect cookie texture!



Sometimes your oven can play tricks. Having a thermometer will ensure you are baking at the right temperature for those perfectly baked cookies!



Variations

Faq
- What if my cookies turn out flat?
Flat cookies might mean too much fat or not enough flour! Make sure to follow the measurements closely and use a proper measuring method.
- Can I skip the chilling time?
Chilling is essential to let the flavors meld and to achieve a better texture. If you skip this, your cookies might spread too much while baking.
- How can I make my cookies more chewy?
For chewier cookies, try adding an extra egg yolk or using more brown sugar instead of white sugar.
- What can I do if my dough is too sticky?
If the dough is sticky, adding a bit more flour gradually until the right consistency is reached can help. But be careful, not to add too much!
- Is it possible to freeze the cookies?
Absolutely! Bake the cookies and let them cool completely, then freeze them in an airtight container. They’ll be delicious even when thawed!
- How do I know when the cookies are done?
Watch for a slight golden edge; they will firm up as they cool. Remove them from the oven when they are still soft in the center for a perfect chewy texture!
