Place the sliced peaches into the blender, ensuring they are evenly distributed for smooth blending.
Add the ice cubes to the blender, giving the mixture a frosty foundation.
Pour in the honey or simple syrup to add natural sweetness and enhance the peach flavor.
Secure the lid on the blender and blend on high speed until the mixture is smooth and icy, about 30 to 45 seconds. You should see a uniform, frosty texture.
Check the consistency and, if needed, add a bit more ice and blend briefly again to achieve a thicker, more slush-like texture.
Pour the frosty peach mixture into glasses, using a spoon to help fill any overflow for a clean presentation.
Garnish with a peach slice or a sprig of mint if desired for an appealing finish.
