Abstract	We construct a two-dimensional action that is an extension of spherically symmetric Lovelock gravity. In spite that the action contains arbitrary functions of the areal radius and the norm squared of its gradient, the field equations are second order and obey the Birkhoff's theorem. Similar to the spherically symmetric Lovelock gravity, the field equations admit the generalized Misner-Sharp mass that determines the form of the vacuum solution. The arbitrary functions in the action allow for vacuum solutions that describe a larger class of nonsingular black-hole spacetimes than previously available.
