  We derive a covariant expression for the renormalized holographic
entanglement entropy for 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.
