Soften dates (optional): You want your medjool dates to be soft for easy blending. If your dates are hard, soak them in hot water for 10 minutes first, then drain and gently pat them dry.
Drain tofu: Drain excess liquid from the silken tofu and firm tofu.
Blend: Add medjool dates, silken tofu, firm tofu, peanut butter, and vanilla extract to a blender and blend until smooth.
Serve immediately or chill in the fridge for a thicker consistency.
