How can I design the Doomsday Device (tm) to destroy the world?

Destroy is such a variable word.

I think a complete resurfacing is probably possible with current
technology.

You'll need to set up a plant to make some nuclear warheads.
A million megaton yield ones should just about do.

Now, launch these towards Ceres, and detonate each one at the appropriate
point, one every 30 seconds for a year.

I suspect the cheapest way would be to do a couple of Jupiter flybys
to put it onto an earth impacting orbit.

Smacking Ceres into earth at some 15Km/s or so should liberate on the
order of 1000000000000000 megatons.

Actual "blow the earth into little bits" is going to be harder.
