What are key limes?

Key limes are a small, round citrus fruit known for their thin skin, intense aroma, and tart, slightly floral flavor. They’re more acidic and fragrant than regular (Persian) limes, which is what gives classic key lime desserts like key lime cheesecake their signature bright taste. You’ll most often find fresh key limes in grocery stores during late fall through spring, especially in the produce section near other citrus fruits. Because they’re tiny and contain very little juice, many cooks opt for bottled key lime juice, which is widely available year-round and works beautifully in baking and desserts when fresh key limes aren’t in season. I use Nellie and Joe’s brand key lime juice, which you can find in your market’s juice aisle.

How to Make Key Lime Pie Cookies

Bake the Cookies

Preheat oven to 350°F. Line two baking sheets with parchment paper.
In a large bowl, use a hand mixer to combine the butter and sugars. Add the eggs and vanilla and mix until combined.
Add the flour, graham cracker crumbs, salt, baking soda, and baking powder. Mix until fully combined.
Use a large scoop to create 15 equally sized dough balls. Roll into smooth balls, then roll in the remaining graham cracker crumbs. Place 6 on each baking sheet and gently flatten into hockey puck shapes.
Bake 11 to 13 minutes. Remove from oven and use the bottom of a measuring cup to gently press an indent into the center of each cookie. Let cookies cool completely.

Make the Filling

In a large bowl, use a hand mixer to combine cream cheese, sweetened condensed milk, lime juice, lime zest, and powdered sugar until smooth.
Spread filling into the center of each cookie. Chill at least 30 minutes.
Top with whipped cream and a lime wedge before serving.

Recipe Tips

Use fresh lime zest for the brightest flavor.
Don’t overbake—the cookies should be pale and soft.
Store cookies in the refrigerator in a covered container for up to 4 days.
Chill before serving for best texture.
