Add the mango chunks, ice cubes, honey, and lemon juice into the blender.
Blend on high speed until the mixture is smooth and icy, about 30-45 seconds, making sure to break down all the mango pieces.
Stop the blender and check the consistency—if it’s too thick, add a splash of water or juice and blend again until it reaches your desired texture.
Pour the slushie into glasses, revealing its vibrant orange color and icy texture.
If desired, garnish with a small slice of mango or a sprig of mint for a pop of color.
Serve immediately with a straw, enjoying the refreshing, icy burst of tropical flavor.
