Boil 2. 0 cups (16. 0 oz / 473 g) of salted water over medium heat, add the cauliflower, reduce heat, and simmer for 10 minutes before draining into a large bowl.
Warm 1. 0 cup (8. 0 oz / 227 g) almond milk, 0. 33 cup (2. 6 oz / 74 g) heavy cream, 4 garlic cloves, 0. 25 tsp. (0. 02 oz / 0. 5 g) nutmeg powder, and 0. 1 tsp. (0. 01 oz / 0. 3 g) salt and black pepper in a small pot over medium-low heat for 1 to 2 minutes while the cauliflower cooks.
Mash the drained cauliflower until perfectly smooth, then add 4. 0 tbsp. (2. 0 oz / 57 g) unsalted butter, 2. 0 tbsp. (1. 0 oz / 28 g) cream cheese, and pour in the warm almond milk mixture, stirring vigorously to combine all ingredients.
Garnish the finished dish with 1. 0 tbsp. (0. 1 oz / 3 g) of chopped fresh scallions and serve immediately.
Drain Thoroughly: Cauliflower holds a lot of water.
After boiling and draining, lightly press the florets with a clean kitchen towel to remove excess moisture and prevent a soggy mash.
Roast the Garlic: For a deeper, sweeter flavor profile, swap the raw garlic boiled in the cream mixture for a whole head of roasted garlic squeezed directly into the mash.
