Instructions

1. Prep the Key Lime Filling

1. In a medium mixing bowl, beat the 12 oz of softened cream cheese with a hand mixer on medium speed until completely smooth and free of lumps.

2. Add the 2 tbsp of sour cream, 1 cup of sweetened condensed milk, 2 tbsp of lime zest, and 1/2 cup of lime juice.

3. Beat on medium-low speed until the mixture is completely uniform, thick, and creamy.

4. Cover the bowl and place it in the refrigerator to chill and set for a minimum of 1 to 2 hours before assembling the cookies.

2. Mix the Dry Cookie Ingredients

1.Preheat oven to 350F and line baking sheets with parchment paper. 

2. In a large bowl, whisk together the all-purpose flour, graham cracker crumbs, cornstarch, baking powder, baking soda, and salt.

3. Cream the Wet Cookie Ingredients

1. Beat the softened butter and cream cheese together on medium-high speed until completely smooth and creamy (about 2 minutes).

2. Add the brown sugar and granulated white sugar. Beat on medium speed for another 2 to 3 minutes until light and fluffy.

3. Add the room-temperature eggs one at a time, followed by the vanilla extract. Beat until fully incorporated and smooth.

4. Combine and Shape the Dough

1. Gradually add the dry ingredient mixture to the wet ingredients. Mix on low speed just until a soft cookie dough forms (do not overmix!).

2. Scoop out 12 4oz portions of dough and roll into smooth balls. Place the dough balls on a parchment-lined baking sheet. Using the back of a small measuring cup or your thumb, gently press a deep well into the center of each cookie to create a cup shape.

5. Bake and Cool

1. Bake the chilled cookies for 12 to 14 minutes, or until the edges are a light golden brown but the centers still look slightly soft.
2. As soon as they come out of the oven, use the back of a spoon or measuring cup to gently redefine the center well while they are warm. Let cool completely on wire racks.

6. Make the Whipped Cream & Assemble

1. Make the Whipped Cream: In a chilled medium bowl, combine the cold heavy cream, powdered sugar, and vanilla extract. Use a hand mixer or whisk to beat on medium-high speed until stiff peaks form. Transfer to a piping bag fitted with your favorite star tip (or set aside in the fridge).

2. Once the cookies are completely cool, scoop or pipe a generous amount of the chilled key lime filling into the well of each cookie.

3. Pipe a dollop of the fresh whipped cream onto each cookie, dust with remaining graham cracker crumbs, and garnish with a fresh lime wedge before serving!

Tips for Cookie Success

 Let the Filling Chill: Don’t rush the chilling process for the filling! Giving it at least 1 to 2 hours in the fridge allows it to set up beautifully so it holds its shape inside the cookie cups.

 Cold Heavy Cream is Key: To get the best volume and stiffest peaks, make sure your heavy cream is ice cold before whipping. You can even chill your mixing bowl and beaters in the freezer for 5 to 10 minutes beforehand.

 Keep Ingredients at Room Temp: Your eggs, cream cheese, and butter for the cookie base must be room temperature to combine smoothly without leaving unappealing lumps in your batter.

Storage and Freshness

Because the filling and whipped cream are made with dairy, these cookies must be stored in the refrigerator.

Place them in a single layer inside an airtight container for up to 3 to 4 days. For the best texture, remove them from the fridge about 15-20 minutes before enjoying so the cookie base can soften slightly to its perfect chewiness!
