We report the detection of several molecular gas-phase and ice absorption features in three photometrically-selected young stellar object (YSOs) candidates in the central 280~pc of the Milky Way. Our spectra, obtained with the Infrared Spectrograph (IRS) onboard the {\it Spitzer Space Telescope}, reveal gas-phase absorption from CO$2$ (15.0 $\mu$m), C$2$H$2$ (13.7 $\mu$m) and HCN (14.0 $\mu$m). We attribute this absorption to warm, dense gas in the massive YSOs. We also detect strong and broad 15.2 $\mu$m CO$2$ ice absorption features, with an absorption profile indicating the presence of thermally processed CO$2$ ice. Our IRS observations demonstrate the youth of these objects, and provide the first spectroscopic identification of massive YSOs in the Galactic Center.
