Preheat the oven to 350 degrees. Line two baking sheets with parchment paper.
Combine the butter and sugar in a stand mixer and beat until light and fluffy, about 5 minutes. Stir in the vanilla and egg and scrape down the side of the bowl.
In a large bowl, combine the flour, salt, and baking soda. Mix with a low speed until combined well.
Add half a cup of the dry ingredients to the butter mixture at a time, alternately with the milk, beginning and ending with the flour.
Scoop batter onto baking sheets spaced 2 inches apart on all sides, using a 1/4 cup measuring cup. Makes 12 cakes in total.
Place the baking sheets in the oven and bake for 15-18 minutes at 350 degrees, switching them halfway through.
Remove the baking sheet from the oven and place on a cooling rack and allow to cool completely.
For the Filling
Mix together the powdered sugar and butter using a stand mixer on medium speed until light and fluffy.
Stir in salt and vanilla. Beat in marshmallow cream until fully combined. Add vanilla bean paste and stir to combine.
To Assemble
On the flat side of half the cakes, spread 1/3 cup of filling. Make sure that the filling stays on but is spreadable.
Place it in the refrigerator if it is sliding off or add a bit more powdered sugar if necessary. If it's too soft, add a few drops of milk.
To make a sandwich, put the rest of the cakes on top. Enjoy right away or store in the refrigerator.
