Method
COOKIES
- Beat butter in a large bowl using a handheld mixer or stand mixer until creamy. Scrape down the sides and bottom with a spatula. Add sugar and beat on medium speed for about 1 minute. Add egg yolks and vanilla. Mix until combined and scrape down sides again.
- In a separate bowl, combine salt, flour, and graham cracker crumbs. Add to butter mixture. Beat on low speed until just combined and dough is formed. (Dough will be a bit crumbly but will come together.)
- Using a cookie scoop or your hands, shape 1 Tbsp size scoops into balls and roll in granulated sugar. Place on a plate lined with waxed paper. Using your thumb or the back of a measuring spoon, gently press an indent into the cookies. If they begin to crack, just pinch back together.
- Chill in the freezer for 20-30 minutes.
- Preheat oven to 350 degrees F. Line cookie sheets with parchment paper.
FILLING
- Using a handheld or stand mixer, beat cream cheese and sugar until smooth.
- Add key lime juice and lime zest. Mix well. Add sour cream and beat until combined. Filling will be on the thinner side.
ASSEMBLY
- Remove cookies from freezer. Spoon filling into each cookie until it is almost overflowing.
- BAKE: Bake for 12-13 minutes or just until the edges are beginning to turn light golden brown. Do not overbake. (The filling will deflate a little as it cools.)
- Sprinkle just a few flakes of lime zest on the cookies after coming out of the oven. Transfer to a wire rack to cool completely.
STORAGE
- Store in an airtight container in the refrigerator for up to a week or in the freezer for up to 3 months. When ready to use, thaw overnight in the refrigerator. Unbaked cookie dough may be frozen for up to 2 months.
Notes
AMOUNT: This is a large-batch recipe, perfect for parties, bake sales, or freezing for later because they are always a crowd-pleaser! For a smaller batch, all ingredients can easily be halved.
