Cream Cheese Filling
Mix the cream cheese, powdered sugar, vanilla extract, and half-squeezed lemon in a small bowl. Using a teaspoon, scoop 10 portions of the cream cheese mixture onto a parchment paper-lined plate. Freeze the cream cheese filling for at least one hour or until frozen solid.
Cookies
Add the lemon cake box mix, vegetable oil, eggs, vanilla extract, and lemon zest to a bowl, and whisk together. Follow the instructions on the box for the cake mix. Place the cookie dough mixture in the refrigerator for at least one hour.
Assembly
Preheat the oven to 350℉. Using an ice cream scoop, scoop out the cookie dough, flatten it in your palms, and add one of the frozen cream cheese portions. Roll up the cookie dough into a ball and place it onto a cookie sheet lined with parchment paper. Slightly flatten the cookie dough ball. Bake the cookies for 10 to 12 minutes.
Cream Cheese Frosting
Mix the softened cream cheese and store-bought frosting until fluffy. After the cookies have cooled down, top the cookies with the frosting and sprinkle some crushed graham crackers to decorate and enjoy!
