Prepare the Peanuts: Soak the peanuts in water overnight. Drain and rinse them thoroughly before use.
Blend the Peanuts: In a blender, combine the soaked peanuts with 2 cups of fresh water. Blend until smooth.
Strain the Mixture: Use a nut milk bag or a fine mesh strainer to strain the peanut milk into a bowl, discarding the solids.
Sweeten and Flavor: Mix in the honey or maple syrup, vanilla extract, and a pinch of salt. Blend again to combine thoroughly.
Chill and Whip: Refrigerate the peanut milk for at least an hour before using. Once chilled, whip it with a mixer until light and fluffy. Check out the right Peanut Milk Frosting, cake tools, and ingredients that you need here.
