Instructions
Preheat the oven to 350°F. Rub softened butter all around the inside of 3 8-inch cake pans. Line the bottoms of the pans with parchment paper and then dust them with flour. Set aside.
In a medium bowl, add the flour, baking powder, pudding mix, and salt. Whisk them together and set aside.
Add the butter and sugar to your mixing bowl and beat them together with an electric mixer until they are light and fluffy. Scrape the bowl.
Add one egg at a time and gently beat it with the mixer to incorporate before adding the next egg. Scrape the bowl and add the vanilla. Mix to combine.
Add half the flour mixture to the mixing bowl and stir to combine. Pour the cream soda in and stir to combine. Then add the remaining flour and stir to combine. Scrape the bowl and check for any dry pockets of flour.
Pour the cake batter evenly among the cake pans. Bake for 30 - 40 minutes or until a toothpick inserted in the center comes out clean. Allow the cakes to cool completely before frosting.
Assemble the frosting:
Add the butter to your mixing bowl. Beat it with an electric mixer until it is smooth and creamy. Scrape the bowl. Add the powdered sugar one cup at a time and beat it until completely combined before adding the next cup.
Beat the butter and sugar together for 3 minutes until light and fluffy. Add the marshmallow fluff and vanilla and continue to beat for an additional 2-3 minutes.
Assemble the cake:
Use the frosting to ice between the layers of the cake and all over the tops and sides of the finished cake. Chill until serving time.
Heat the butterscotch sauce in the microwave for 10 - 15 seconds or until it is loose and drizzly. Serve alongside the cake in a small cream pitcher for drizzling on top of each slice.
