These delightful sandwich cookies are filled with a tangy and creamy key lime pie filling, perfect for a refreshing treat. They’re easy to make and sure to brighten up any dessert table with their zesty flavor.
Start by heating your oven to 375°F (190°C) and line two baking sheets with parchment paper. In a bowl, whisk together the flour, graham cracker crumbs, baking soda, baking powder, and cinnamon. In a separate bowl, cream the butter and half a cup of sugar using an electric mixer until it’s light and fluffy. Add the egg yolk and vanilla, mixing until everything comes together. Then, gradually add the dry ingredients and keep mixing until the dough forms and sticks together, which should take about a minute or two.

Next, roll the dough into 1-inch balls and coat each one in the remaining sugar. Place them on your prepared baking sheets, leaving a little space between each. Bake for 6 to 7 minutes, just until the bottoms start to turn golden. Let the cookies cool on the sheets for about 5 minutes before transferring them to a wire rack to cool completely.

While the cookies are cooling, zest all three limes and set that aside. Juice two of the limes and mix the juice with the lime zest into some softened cream cheese and confectioners’ sugar. Beat everything together until smooth and creamy.
