Place all ingredients in a blender cup and blend until smooth. Taste and adjust seasonings to taste. Store in the refrigerator. Enjoy!
Notes
Regular peanut butter has a stronger taste and smoother texture than natural peanut butter but both are good! You may need to adjust the amount of soy sauce and sugar slightly depending on what type you use.
This peanut sauce will thicken in the refrigerator so you may need to let it sit at room temperature or heat it in the microwave for a few seconds before serving.
