We show how $CP$ violating $B$ meson oscillations in conjunction with baryon number violating decays can generate the cosmological asymmetry between matter and antimatter, and explore the parameter space of a simple, self-contained model, which can be tested via exotic $B$ meson decays, and via the charge asymmetry in semileptonic decays of neutral $B$ mesons.
