Chocolate Protein Fudge

August 17, 2026 Total time: 2 hrs 10 min Makes: 6 servings (2 squares each)

This is fudge in the truest sense, dense, rich, and a little decadent, except it's built on nut butter and protein powder instead of a pound of butter and sugar. No candy thermometer, no stove, just stir and let the fridge do the rest.

It satisfies a chocolate craving hard, and because it's this dense, a couple of small squares actually does the job. I keep a pan of this in the freezer more often than I'd like to admit.

Tips & swaps

  • Natural nut butter (just nuts and salt) gives the smoothest texture, no-stir varieties can make this too stiff.
  • This softens quickly at room temperature since it's built on coconut oil, keep it in the fridge or freezer.
  • Two squares is the intended serving here, they're rich and dense.
