  • Airtight storage container

    • You can use any type of milk for this syrup. You can always use nonfat milk, soy, or even coconut milk and the only difference will be slight changes in the creaminess of the mixture. If using strongly flavored milk like coconut or almond milk for example you will get hints of coconut and almond in the mixture but both flavors naturally pair really well with peanut butter.
  • Water
    • Adding water to the mixture can help you thin out or dilute the mixture if it becomes too thick or sweet.
  • Sugar
    • Any sweetener can be used such as white sugar, brown sugar, agave, honey, stevia, etc. Slight changes will occur in the consistency of the syrup but these changes are very subtle.
  • Peanut butter
    • Any peanut butter can be used from smooth and creamy to crunchy peanut butter. The only difference will be a smooth syrup to a chunky crunchy syrup.
  • Vanilla extract
    • This flavoring is totally optional to the recipe but really adds to the flavor.
