Make the Cake Batter
Preheat the oven to 350°F (175°C) and grease your cake pans.
In a bowl, whisk together the flour, baking soda, salt, cinnamon, and nutmeg.
In a separate bowl, beat the butter, brown sugar, and granulated sugar until light and fluffy. Add the eggs, molasses, and vanilla extract, mixing well. Stir in the softened oats, then gradually mix in the dry ingredients until just combined.
Bake the Cake
Divide the batter evenly between the pans and bake for 25–30 minutes, or until a toothpick inserted into the center comes out clean. Let the cakes cool completely.
Prepare the Cream Filling
Beat the butter until smooth. Add the powdered sugar, marshmallow cream, and vanilla, mixing until light and fluffy.
Assemble the Cake
Place one cake layer on a serving plate. Spread the cream filling evenly over the top, then place the second layer on top. Press gently to secure.
