%X We measure the branching fraction and <i>CP</i>-violating flavor-dependent rate asymmetry of B<sup>0</sup> → π<sup>0</sup> π<sup>0</sup> decays reconstructed using the Belle II detector in an electron-positron collision sample containing 387 ×10<sup>6</sup>B―B pairs. Using an optimized event selection, we find 126±20 signal decays in a fit to background-discriminating and flavor-sensitive distributions. The resulting branching fraction is (1.25 ±0.23)×10<sup>−6</sup> and the <i>CP</i>-violating asymmetry is 0.03 ±0.30.
