  We derive a covariant expression for the renormalized holographic
entanglement entropy for Conformal Field Theories (CFTs) dual to Quadratic
Curvature Gravity in arbitrary dimensions. This expression is written as the
sum of the bare entanglement entropy functional obtained using standard conical
defect techniques, and a counterterm defined at the boundary of the extremal
surface of the functional. The latter corresponds to the cod-2 self-replicating
part of the extrinsic counterterms when evaluated on the replica orbifold. This
renormalization method isolates the universal terms of the holographic
entanglement entropy functional. We use it to compute the standard C-function
candidate for CFTs of arbitrary dimension, and the type-B anomaly coefficient c
for 4-dimensional CFTs.
