Soak 1 cup of raw cashews in water for at least 4 hours or overnight. If you're short on time, boil the cashews for 10-15 minutes. Drain and rinse before using.
Pit and chop 1/2 cup of dates. Medjool dates work best for their natural sweetness and soft texture.
Add the soaked cashews, dates, 1/2 cup water, vanilla extract (optional), maple syrup (optional), and salt in a high-speed blender.
Blend on high speed until the mixture is rich, creamy, and smooth.
If the glaze is too thick, add water one tablespoon at a time until you reach the desired consistency.
Taste the glaze and adjust sweetness or salt if needed. Add more dates or maple syrup for extra sweetness or a pinch of salt to balance the flavors.
Transfer the glaze to an airtight container and store it in the refrigerator. Use it as a drizzle, dipping sauce, or topping.
