Preheat your oven to 350°F

Sift the cake mix to ensure that no lumps of cake mix will be in your whoopie pies

Mix together the cake mix, eggs and oil until a smooth, thick batter appears

Scoop by the tablespoon onto a parchment lined cookie sheet just like you would cookies

Bake for 8-10 minutes and once done, let completely cool before icing

For the filling, start by creaming your cream cheese for 2-3 minutes, then add in your icing sugar cup by cup followed by your vanilla extract.

Using a butter knife, spread the filling on one side of a whoopie cookie and sandwich with another to create your perfect whoopie pie.
