Preheat oven to 350°F (180°C). Spread hazelnuts on a baking sheet and roast for 10 minutes.
Add hazelnuts to a food processor and blend for 5–7 minutes until smooth and buttery, scraping down the sides as needed.
Add melted chocolate, vanilla extract, and salt. Blend until fully combined. Add almond milk 1 tablespoon at a time until the spread reaches your desired consistency.
Transfer to a jar and store in the refrigerator for up to 2 weeks. Let sit at room temperature for easier spreading.
