That is the Earth.
Mars. Edit : As far as I know the ice caps contain water ice as well as frozen carbon dioxide.
The greatest volume of water on Earth is contained in the oceans, which hold about 97% of the planet's total water supply. The Pacific Ocean is the largest and contains more water than all the continents combined. Additionally, freshwater is primarily found in glaciers and ice caps, particularly in Antarctica and Greenland, but these represent a small fraction compared to the vast amounts in the oceans.
Earth has, and it's been suggested that Mars may have.
Roughly 97% of the world's water is liquid, mainly found in oceans, seas, lakes, and rivers. The remaining 3% is frozen in glaciers and ice caps.
Approximately 68.7% of the Earth's freshwater is locked in ice caps and glaciers. This includes the vast ice sheets of Antarctica and Greenland, which store the majority of this frozen water. In total, ice caps and glaciers represent a significant portion of the planet's freshwater resources.
Two planets have frozen ice caps: Earth and Mars. In November 2012 scientists found evidence of ice on the poles of Mercury. However, only the Earth has oceans.

Mars has frozen water at its south pole in the form of polar ice caps made up of water and carbon dioxide ice.
The oceans contain about 97% of the Earth's water. The remaining 3% is found in glaciers, ice caps, groundwater, lakes, rivers, and in the atmosphere.

Ice caps are areas of frozen water or gases that are created by the colder conditions near a planet's poles. In Earth's case, its tilt compared to its orbit gives us seasons, but the shallow angle of sunlight (plus the higher albedo or reflectivity of snow) means that there are large, permanently frozen ice caps in Greenland and in Antarctica.
Earth has, and it's been suggested that Mars may have.
The frozen ice caps on Mars are composed of a mixture of water and carbon dioxide ice. These ice caps play a vital role in the planet's water cycle and are crucial for understanding Mars' climate history. Water ice has been detected beneath the surface of the ice caps, providing insight into potential water resources on the planet.

It is very likely that Earth is the planet with the largest amount of frozen water.
