# How-To Steps:
01 - Preheat the oven to 350°F. Line two baking sheets with parchment paper.
02 - In a medium bowl, whisk together the flour, cocoa powder, baking soda, baking powder, and salt.
03 - Using an electric mixer, beat the sugar, butter, and oil in a large bowl until light and fluffy.
04 - Add eggs one at a time, beating well after each addition, then mix in the vanilla extract.
05 - Alternately add the flour mixture and buttermilk to the wet ingredients, beginning and ending with the flour mixture. Mix just until combined.
06 - Drop 2-tablespoon-sized mounds of batter on the prepared baking sheets, spacing them about 2 inches apart.
07 - Bake for 10 to 12 minutes until cakes spring back when lightly touched. Let cool on sheets for 5 minutes, then transfer to a wire rack to cool completely.
08 - Beat the butter until smooth. Gradually add powdered sugar, then blend in marshmallow creme, vanilla extract, and salt. Beat until fluffy.
09 - Spread or pipe the filling onto the flat side of half the cakes, then top with the remaining cakes to form sandwiches.
10 - Refrigerate the assembled sandwiches for 30 minutes to achieve the best texture before serving.
