Beat 1/2 cup butter and sugar until fluffy. Add egg and vanilla. Mix in flour, cocoa, 1 tsp baking soda, and salt, alternating with buttermilk.
Drop 2-tablespoon mounds onto parchment-lined baking sheets, spacing 2 inches apart.
Bake at 375°F for 10-12 minutes until the tops spring back when lightly touched. Cool completely.
Make filling: beat 1/2 cup softened butter with powdered sugar until fluffy, then fold in marshmallow fluff and 1 tsp vanilla.
Spread a generous spoonful of filling on the flat side of one cake, sandwich with another. Repeat with remaining cakes.
