Add the pitted cherries, mint leaves, honey, lemon juice, and ice cubes into the blender.
Blend on high speed until the mixture is smooth, vibrant in color, and has a slightly granular, icy texture.
Stop the blender and check the consistency—add a splash more lemon juice or honey if you want it more tart or sweeter, then briefly blend again.
Pour the slushie into glasses, ensuring each is filled with the chilled, frosty mixture.
Garnish with a sprig of mint or a few whole cherries for a colorful presentation.
Enjoy immediately with a straw or a spoon to savor the refreshing, icy sweetness.
