We theoretically investigate twisted structures where each layer is composedof a strongly correlated material. In particular, we study a twisted t-J modelof cuprate multilayers within the slave-boson mean field theory. This treatmentencompasses the Mott physics at small doping and self consistently generatesd-wave pairing. Furthermore, including the correct inter-layer tunneling formfactor consistent with the symmetry of the Cu $d_{x^2-y^2}$ orbital proves tobe crucial for the phase diagram. We find spontaneous time reversal (T)breaking around twist angle of $45^\circ$, although only in a narrow window oftwist angles. Moreover, the gap obtained is small and the Chern numbervanishes, implying a non-topological superconductor. At smaller twist angles,driving an interlayer current however can lead to a gapped topological phase.The energy-phase relation of the interlayer Josephson junction displays notabledouble-Cooper-pair tunneling which dominates around $45^o$. The twist angledependence of the Josephson critical current and the Shapiro steps areconsistent with recent experiments. Utilizing the moir\'e structure as a probeof correlation physics, in particular of the pair density wave state, isdiscussed.
