    Keto Peanut Butter Fudge

    Calling all peanut butter lovers! If you have a sweet tooth for peanut butter then this 4 ingredient fudge is just the treat for you! Decadently rich in flavor without all the sugar!

    This keto peanut butter fudge is so rich that one small piece is all you need.  I love to have a piece after dinner just to satisfy that sweet craving.  Speaking of dinner, you should definitely checkout my recipes for Unstuffed Pepper Casserole, Italian Stuffed Sausage Bake, and Baked Feta Tomato Pasta!

    If you are a peanut butter lover like me, you will have this sweet treat in your freezer at all times.  This along with my keto chocolate fudge keeps all of my sweet cravings under control!

    Unsweetened peanut butter

    When you are looking for a peanut butter for this fudge recipe, make sure you find one with the only ingredient being peanuts and maybe salt.  So many store bought peanut butters are filled with sugar and added oil and that stuff is just not necessary!

    The process for making this fudge couldn't be any easier.  I use the microwave for simplicity!  I also love to use my microwave to make keto 90 second bread and keto mug cakes.

    Recipe tips and notes

    • Use peanut butter with the only ingredients being peanuts and maybe salt
    • If you do not like to use a microwave, you can place the mixing bowl over a saucepan of simmering water and stir until the peanut butter and butter are melted.
    • If you have a peanut aversion or allergy, you can also use almond butter

    Ingredients

    • 9 Ounces sugar free creamy peanut Butter
    • ⅔ Cup Powdered Sweetener (Click here to see my favorite on Amazon)
    • ½ Cup butter, softened
    • ¼ Cup heavy cream

    Instructions

    • Line the inside of a 8x4 loaf pan with parchment paper, leaving the edges long enough to pull fudge out once it's set. Spray with cooking spray and set aside.
    • Place peanut butter and butter inside a microwave safe bowl. Microwave for 1 minutes or until butter is melted and peanut butter is soft enough to mix.
    • To the peanut butter and butter, stir in the heavy heavy cream and sweetener. Stir until all ingredients are combined equally and there are no lumps.
    • Pour fudge mixture inside already prepared loaf pan. Chill in refrigerator until fudge is set. Should take about a hour. Slice into 14 equal portions and serve. Keep stored in the refrigerator or freezer.

      OMG, this is so tasty. Creamy, and just satisfying to your mood and taste buds. Jen just seems to knock it out of the park. This is a woman who preaches what SHE does. OMG. Love her.

      Most most peanut butter has natural sugar

      I grew up with my mom making peanut butter fudge on the stovetop, and I have missed it so much. This recipe is phenomenal: delicious! Even my husband says it tastes like my mom's fudge, and he's not even Keto! Thank you!

      Hey Jennifer:

      Have you made a fudge with chocolate yet? Or maybe chocolate and peanut butter?

      Thanks.

      SO good! I made this and noticed it matches the process for the chocolate fudge, to which I added natural peanut butter, btw, so I knew this was going to be awesome! Thank you!
