Preheat oven to 350°.Cream together the butter, granulated sugar and brown sugar.
Add the egg and vanilla. Mix until light in color and creamy.
Add in the dry ingredients (flour, crushed graham crackers, baking soda, baking powder and salt), mix into the dough. Mix until completely combined.
Portion out the dough into 1/2 cup portions. Roll into a ball and arrange 6 onto each cookie sheet. Press down slightly on the cookie dough, flattening it a bit.
Bake for 12-15 minutes, until the cookies are turning golden brown.
After you pull the cookies out of the oven, use the bottom of a measuring cup or drinking glass and gently press the center of the cookie down, making a an indent for the pie filling to go.
Allow the cookies to cool completely.
Once the cookies have cooled completely, make the filling by creaming the cream cheese until smooth.
Add in the can of sweetened condensed milk, mix until thoroughly combined.
Next, add in the powdered sugar and lime juice. Remember, you can always add in more lime juice, you can't take some out. So start small and add more to your preference.
Once your pie filling is finished, scoop and spread it into the center of each of your cookies.
Place in the fridge until ready to serve.
Right before serving, top with a dollop of whipped cream and a fresh lime slice.
