Easy to Make - Whoopie Pies

First off, congratulations to lucky link up #7, who was picked by Random.org to win my vintage peanut butter parfait dishes giveaway.  These will go to DogsMom.   She is always looking out for thrifty finds, so I think they'll go to a good home!

I've never made whoopie pies before, partly because they remind me of the Moon Pie Incident of 1982, and partly because they seem complicated.  But Family Circle magazine had a recipe in their April issue that is so easy - and they turned out delicious!

Cake:
1 box devil's food cake mix
3 large eggs
1/2 cup vegetable oil
1/2 tsp baking powder
3 tbsp water

Filling:
1 stick butter, softened
2 cups confectioners' sugar
1 1/2 tbsp. water
1/2 tsp. vanilla extract

Heat oven to 350*.  Coat 3 large cookie sheets w/ nonstick cooking spray.
In large bowl combine cake ingredients.  Beat on low 30 seconds, then on medium for 2 minutes.  Drop by heaping tablespoonfuls onto cookie sheets, spacing 2 inches apart.  Bake at 350* for 12 minutes.  Let cookies stand on sheets for 2 minutes, then transfer to wire rack to cool.

While cakes are cooling, beat butter until smooth.  Add sugar, vanilla, and water.  Beat on low speed until blended, then medium-high until smooth.  Spread a heaping tablespoon of filling onto cake.  Sandwich with second cake.
