Keto Peanut Butter Fudge | Kevin Wagonfoot

Look, I’m not gonna pretend I invented this recipe or anything—I just know what it’s like to be on keto and desperately miss actual candy. This peanut butter fudge from the 5-Ingredient Keto Cookbook changed my game because it tastes indulgent without any of the guilt or the blood sugar rollercoaster.

The best part? I can make a whole batch with five ingredients I actually have on hand. No weird specialty stuff, no complicated steps. Just real food that happens to fit my keto life.

Why This Works for Keto

This fudge works beautifully for keto because it’s built on peanut butter and fat—the exact macro combo that keeps you satisfied and in ketosis. There’s no hidden sugar doing sneaky things to your carb count, just straightforward ingredients that align with how you’re eating. It’s the kind of treat that doesn’t leave me wondering an hour later why I’m starving again.

Keto Peanut Butter Fudge

Keto Peanut Butter Fudge

Indulge in this rich and creamy keto peanut butter fudge that’s quick to prepare and deliciously satisfying. Perfect for satisfying sweet cravings while keeping your carb count low.

Prep: 10 min Total: 10 min Serves: 2

Ingredients

  • 1/2 cup peanut butter
  • 1/4 cup coconut oil
  • 1/4 cup powdered erythritol
  • 1/2 teaspoon vanilla extract
  • a pinch of salt

Instructions

  1. In a mixing bowl, combine the peanut butter and melted coconut oil. Stir until smooth; this creates a creamy base for your fudge. Ensure there are no lumps for the best texture.
  2. Add the powdered erythritol, vanilla extract, and a pinch of salt to the mixture. Stir thoroughly, as this will sweeten and flavor the fudge. Taste for sweetness and adjust if necessary.
  3. Line a small dish with parchment paper for easy removal. Pour the fudge mixture into the dish and spread evenly. This helps the fudge set properly without sticking to the dish.
  4. Place the dish in the fridge for about 30 minutes, or until the fudge is firm. This chilling time allows it to set nicely for easy slicing and a great texture.
  5. Once set, remove the fudge from the dish using the parchment paper. Cut it into squares for serving. Enjoy your delicious, homemade keto treat!

Tips & Variations

  • Press the mixture into a parchment-lined pan and chill it fully before cutting. Trust me, premature cutting is a recipe for crumbles and frustration.
  • If your peanut butter is the natural kind, make sure it's well-mixed before you start so the oil doesn't throw off your ratios.
  • Store these in the fridge or freezer. They'll stay firm and ready to grab when a sweet craving hits.
