  Twisted van der Waals materials have risen as highly tunable platform for
realizing unconventional superconductivity. Here we demonstrate how a
topological superconducting state can be driven in a twisted graphene
multilayer at a twist angle of approximately 1.6 degrees proximitized to other
2D materials. We show that an encapsulated twisted bilayer subject to induced
Rashba spin-orbit coupling, s-wave superconductivity and exchange field
generates a topological superconducting state enabled by the moire pattern. We
demonstrate a variety of topological states with different Chern numbers highly
tunable through doping, strain and bias voltage. Our proposal does not depend
on a fine tuning of the twist angle, but solely on the emergence of moire
minibands and is applicable for twist angles between 1.3 and 3 degrees. Our
results establish the potential of twisted graphene bilayers to create
artificial topological superconductivity without requiring ultraflat
dispersions.
