All Vanilla Whoopie Pies - butter

Method

• Preheat oven to 350F.
• Melt the butter in a saucepan until there's no more foam. Set aside to cool slightly.
• In a bowl, mix the eggs, brown sugar and vanilla extract until the mixture is pale.
• In a separate bowl, mix the flour and baking powder together.
• Pour the melted butter into the egg/sugar mixture and stir to combine.
• Slowly stir the flour into the mixture.
• Knead with your hands to form a big ball of dough.
• Shape the cookies with your hands.
• Arrange them on a silicon mat or parchment paper lined baking sheet.
• Bake for 15 minutes.
• Meanwhile make the frosting filling. In a bowl, with an electric mixer, beat the softened butter and confectioner's sugar until the mixture is pale and smooth.
• With a pairing knife, scrape the seeds out of the vanilla bean, and add them to the frosting.
• Add water and mix to get a smooth mixture.
• When the cookies are cooled, spread a layer of frosting onto half of the cookies.
• Sandwich together with the remaining cookies.
