  In this manuscript we establish local H\"older regularity estimates for
bounded solutions of a certain class of doubly degenerate evolution PDEs. By
making use of intrinsic scaling techniques and geometric tangential methods, we
derive sharp regularity estimates for such models, which depend only on
universal and compatibility parameters of the problem. In such a scenario, our
results are natural improvements for former ones in the context of nonlinear
evolution PDEs with degenerate structure via a unified approach. As a
consequence for our findings and approach, we address a Liouville type result
for entire solutions of a related homogeneous problem with frozen coefficients
and asymptotic estimates under a certain approximating regime, which may have
their own mathematical interest. We also deliver explicit examples of
degenerate PDEs where our results take place.
