Shell model Monte Carlo techniques are used to calculate two-neutrino double beta decay matrix elements. We test the approach against direct diagonalization for ⁴⁸Ca in the complete pf shell using the KB3 interaction. The method is then applied to the decay of ⁷⁶Ge in the (0f_5/2,1p,0g_9/2) model space using a newly calculated realistic interaction. Our result for the matrix element is 0.12±0.05MeV^-1, in reasonable agreement with the experimental value.
