Over medium heat, melt the cream cheese and butter together, add peanut butter and stir to mix together.
Remove from the burner and allow to cool to room temperature - mix once in a while. Then add the vanilla, Sukrin Melis, stevia drops, and whey protein.
Add the heavy whipping cream and blend with a hand mixer until creamy.
Pour into the greased pan and spread evenly. Chill entire pan in refrigerator until set - about 3 hours. Drizzle with chocolate sauce - refrigerate for another hour and then cut into 24 servings.
Hand mix all ingredients together until fairly smooth then pour or drizzle over the completely set fudge.
You can use your microwave to melt the butter and pour over softened cream cheese instead of using the burner heat, if you prefer. The fudge does need to be kept in the refrigerator. Adjust the sweetness with the amount of stevia drops you use.
