Primordial black holes are produced in a minimal UV extension to the Higgs inflation with an included $R^2$ term. We show that for parameters consistent with Standard Model measurements and Planck observation results lead to $M_{\rm PBH} \in (10^{-17}, 10^{-15}) M_\odot$ primordial black holes with significant abundance, which may consist the majority of dark matter.
