Finely grate the carrot into a medium mixing bowl or jar, using the fine side of a box grater to create uniform 1/8-inch shreds—this size is important for even flavor distribution and smooth texture. Add the cinnamon, nutmeg, salt, and ground ginger directly to the grated carrot and whisk together to evenly distribute the spices throughout the mixture. This pre-mixing ensures the warming spices will be evenly incorporated into the ice cream without clumping.
Add the room-temperature cream cheese, condensed milk, sugar, and vanilla paste to the carrot-spice mixture from Step 1. Using an electric mixer or whisk, beat the ingredients together until completely smooth and well combined, about 2-3 minutes. I like using condensed milk because it adds richness and natural sweetness without needing extra eggs, and the cream cheese provides that signature carrot cake tang that makes this ice cream special.
Pour the chilled cream into a separate bowl and whip with an electric mixer until it reaches soft peaks—this should take 2-3 minutes depending on the mixer speed. Gently fold the whipped cream into the carrot-cream cheese mixture from Step 2 using a spatula, working in two additions to maintain the airiness of the whipped cream. The goal is a mousse-like consistency that will freeze into a creamy ice cream texture. I find that chilling the cream and mixing bowl beforehand makes a real difference in achieving that fluffy, stable texture.
Transfer the ice cream mixture to a freezer-safe container or jar and cover tightly. Freeze for at least 4 hours, or preferably overnight, until the mixture is fully set and scoopable. For best results, let the ice cream sit at room temperature for 5-10 minutes before scooping to make serving easier.
