Abstract: In this Letter, we study the collinear limit of the Energy-Energy Correlator (EEC) in single-inclusive jet production in proton-proton ($pp$) and proton-nucleus ($pA$) collisions. We introduce a non-perturbative model that allows us to describe the EEC in the entire angular region of the current experiments. Our results for $pp$ collisions show excellent agreement with CMS and ALICE data over a wide range of jet transverse momenta. For $pA$ collisions, we include modifications from the nuclear medium, and our predictions align well with the trends observed in recent ALICE measurements.
