We adapted the Appleby-Battye-Starobinsky (ABS) model of $F(R)$-gravity towards describing
double cosmological inflation and formation of primordial black holes with masses up to $10^{19} g$ in the single-field model. Masses of primordial black holes in this model are beyond the Hawking limit $10^{15} g$, and this allows us to assert that primordial black holes can form a part of cold dark matter. Our results agree with the current measurements of cosmic microwave background radiation within $3\sigma$, but require fine-tuning of the parameters.
