In the bowl of a stand mixer fitted with the paddle attachment, or in a large bowl using a hand mixer, cream the vegan butter until no lumps remain, scraping down the sides of the bowl as needed.
8 tablespoon Vegan Butter
Add peanut butter to the mixer and combine well, again scraping down the sides of the bowl to ensure that everything is fully incorporated.
½ Cup Natural Peanut Butter
With the mixer on low, stream the maple syrup and salt into the peanut butter mixture. Scrape the bowl down and turn the mixer to medium speed to whip up for about 30 seconds.
¼ Cup Maple Syrup, ¼ teaspoon Salt
Now, add the powdered sugar and turn the mixer on low to incorporate. Scrape the bowl down again.
2 Cups Powdered Sugar, sifted
Add non-dairy milk and vanilla and stir on low to distribute. Then turn the mixer to medium and mix until light and fluffy.
1 teaspoon Vanilla Extract, 1 tablespoon Non-Dairy Milk
Use as desired.
