Key Lime Pie Cookies
Key lime pie cookies is made with key lime cream cheese filling and graham cracker cookies. The dessert sandwiches are zesty and sweet!
I’ve been craving zesty desserts recently. Usually I opt for a lemony dessert (like my mom’s lemon bars), but instead I chose key lime for my star ingredients.
Key lime pie cookies are made with a zesty lime cream cheese frosting that is sandwiched between two graham cracker cookies. The two combined create an irresistible flavor combo!
Be sure to have your rolling pin and cookie cutters ready so you have the perfect sized circle cookies to sandwich the creamy key lime frosting in.
How to make key lime cream cheese frosting
These cookies were initially conceived from my idea to make key lime cream cheese frosting. I had key lime juice and key limes so they had to be used some how!
Key lime cream cheese frosting requires five ingredients—cream cheese, butter, powdered sugar, key lime juice and lime zest. Beat the cream cheese and butter together until well blended. Slowly add in the powdered sugar, then beat in the key lime juice and zest for flavor.
You can frost the cookies using a knife, however, I prefer using a piping bag. It make the process quicker and results in a clean, even frosting in every cookie sandwich.
How to bake graham cracker cookies
I tested a couple recipes to find the perfect graham cracker cookie recipe. This yields a thin, but sturdy cookie that is still full of flavor to complement the key lime frosting.
Graham cracker cookies use a combination of all purpose flour and “graham flour” (aka finely crushed graham crackers). The recipe also calls for the usual cookie suspects: eggs, vanilla, butter and brown sugar. Honey also makes an appearance to accent the graham cracker flavor.
After these ingredients are combined, form a disc with the dough and chill it. Then, roll the dough to 1/4-inch thick, cut and bake. I suggest using a 1 1/2-inch round cookie cutter for consistency.
Can you use regular limes instead of key limes?
Yes! However, you will sacrifice taste. If you’re in a jam, I suggest buying a bottle of key lime juice at the store (I found mine at Whole Foods) and using regular lime zest.
What is the difference between key limes and regular limes?
Key limes are smaller than regular limes. They are also smaller and are more yellow. Most importantly, key limes have a more aromatic flavor than regular limes. This produces a more distinct flavor in key lime pie and other key lime recipes.
