  Van der Waals materials like NbSe$_2$ or TaS$_2$ have demonstrated Ising
superconductivity down to atomically thin layers. Due to the spin-orbit
coupling, these superconductors have the in-plane upper critical magnetic field
far beyond the Pauli limit. We theoretically demonstrate that, twisted bilayer
Ising superconductors separated by a ferromagnetic buffer layer can naturally
host chiral topological superconductivity with Chern numbers, which can be
realized in heterostructures like $\mathrm{NbSe_2/CrCl_3/NbSe_2}$. Under
appropriate experimental conditions the topological superconducting gap can
reach $>0.1$ meV, leading to readily observable signatures such as the
quantized thermal Hall transport at low temperatures.
