Destroy the remains of this universe

You take a look around this universe. Only galaxy-sized black holes and a few tiny, insignificant shards of matter and energy scattered here and there remain.

Sophie: "This is some boring universe. Begone!"

A jaunty little motion of your fingers is enough to vaporize every single black hole in the universe into subatomic particles in an instant. For some added 'oomph', you decide to slightly fumble your fingers to evenly distribute every remaining particle in existence for a total and absolute equilibrium.

Now onto the actual matter at hand. You rake your hand across this useless universe in a wide arch, tearing the space-time continuum into shreds. A spectacular show of flashing rainbow-colored light billows out of the tears.

This epileptic horrorshow offends you. You command it to be still, and it stops obediently, and loses its radiance. Now you feel comfortable walking through the shreds of your universe into the subdimensional space that surrounds all universes.

Here, you can sense the presence of countless other universes, most of them equally vast and empty as yours. You turn around to face the humiliated husk of your universe, and then turn the near-infinite canvas of space into a marble-sized trinket.

Sophie: "I could wear this on a necklace. If I had no style. What a self-respecting Goddess would I be if I wore a broken, empty universe on my person?"

You snap your fingers, erasing the universe from the entire multiverse.

Sophie: "Now to create a new, better universe all for myself!"

A clap of your hands causes the immediate creation of a new, empty universe to spawn around you. A new Big Bang. Here, you can fulfill any and all of your wildest fantasies.
