Sure can! However, a food processor does a better job of chopping due to the relatively low spin rate, when compared to a blender, which will struggle due to the less liquid and hard to grind ingredients such as dates. When using a blender, make sure to add all ingredients including milk to help with the blending process. A high powered blender like vitamix will come handy. Also, another helpful tip is to warm the milk and let the dates soak in the warm milk for about 30 minutes to soften them. Add everything to the blender and blend away.
