Melt the butter, combine with cashew butter until creamy. Add cocoa powder, powdered sugar, vanilla extract and sea salt and mix until creamy. If the mixture is difficult to stir together, heat it in the microwave for 15 second increments until it is easier to combine.
Transfer the mixture to a parchment-lined 8” x 8” cake pan, or a 9” x 5” loaf pan for thicker fudge.
Refrigerate fudge for at least 2 hours, or until it has set up completely.
Slice and serve!

Notes
*You can use peanut butter if you love the flavor! Almond butter works too but it will be slightly grainy and will not be quite as creamy/fudgy.
