Primordial black holes are produced in a minimal UV extension to the Higgs inflation with an included R² term. We show that for parameters consistent with Standard Model measurements and Planck observation results lead to M_PBH ∈ (10⁻¹⁶, 10⁻¹⁵) M_⊙ primordial black holes with significant abundance, which may consist the majority of dark matter.
