1 Box Duncan Hines Lemon Cake Mix- and included ingredients

1 Package Cream Cheese

1 stick butter, softened

4 package powdered sugar

1 tsp vanilla

2 tsp milk- or as needed

Prepare Filling by mixing all ingredients until well blended.   Add more or less powdered sugar to thicken the filling to a good consistency- creamy and smooth. Fill pastry bag with thick 'filling' tip- Or fill a ziplock bag and snip the corner. 

Mix cupcake batter and bake according to the box directions. 

Immediately after removing cupcakes from oven begin filling.

Insert tip of icing bag into the center of the cupcake.  Gently squeeze the filling into the cake.  When the cake starts to sort of "swell" remove the filling tip and make a little dollop on top of the cake.  Feel free to frost the cakes with the filling- or like we did here- add a raspberry on top!

These are crazy good.  Duncan Hines is truly the best cake mix- I swear by them, so substitute at your own risk!
