1 cup butter, softened
1/2 cup sugar
2 teaspoons vanilla extract
1/2 teaspoon salt
1/2 cup almond flour
OR 1/2 cup hazelnut flour

STIR espresso and water together in small bowl until espresso is dissolved. Beat butter, sugar, espresso mixture and vanilla on medium speed with electric mixer in large bowl until fluffy.
