Birthday Cake Whoopie Pie

Here is a delicious birthday cake version whoopie pie you can make for anyone on your birthday list.
It starts with a delicious vanilla cake made with buttermilk that gives it such a rich and delicious mouth feel. Before baking, it’s sprinkled with the traditional multicolored birthday sprinkles to give it that traditional and festive birthday themed appeal.

After baking it is filled with a wonderful traditional buttercream that completes this delicious pie and taste just like a slice of birthday cake. Also, you could also put a scoop of ice cream in the middle instead for a real birthday cake and ice cream experience. Two for one!
I use a star tip to pipe the buttercream into each pie to give it a unique look.
Another great way to enjoy these soft and cake like cookies is simply just on their own without any icing!
