These 4-ingredient peanut butter fudge bars are gluten free and totally easy to make. They are a great little protein bar. In fact, each mini bitesize bar has over 8g of protein.
It’s not your traditional fudge, with tons of sugar. The texture is gooey and fudgy with a bit of a snickers taste.
I make it in a loaf tin. It’s then easy to cut into 15 small squares. Because they are quite indulgent, you really don’t need more than that. Obviously if you would prefer a larger portion, you can also cut these into larger bars.
It’s a great recipe to make ahead as they will last for at least a week in the fridge. They also freeze well for up to 3 months for easy snacks when you need them.
The four simple ingredients you need for this recipe are:
- Peanut butter (obviously!)
- Ground almonds
- Maple syrup
- Dark chocolate
It has a gooey base made from peanut butter, almonds and maple syrup. This has a few dark chocolate chips added to the mix. The topping is melted dark chocolate with a bit more peanut butter.
Adding peanut butter to the dark chocolate means you get a lovely, soft texture for the topping. You can use just dark chocolate but it will have a much harder finish.
I hope you try them and enjoy them as much as I do – let me know!

Recipe Tips
- I have used peanut butter but if you prefer another nut or seed butter, then please substitute with that. Just keep the quantities the same. I’ve tried them with almond butter, and they also taste amazing. Try and use quite a smooth and runny one, if you can, so your base is sticky. If it doesn’t seem very sticky as you mix with the other ingredients, then add a little more, so it comes together. It should be really soft and not crumbly.
- I have used dark chocolate chips in this recipe but any dark chocolate will do. Just try and make sure it is at least 70% cocoa solids and that way it’s more chocolatey and less sugary!
- If you want them slightly less sweet, reduce the maple syrup and add more nut butter. The maple not only adds a sweetness, but it adds to the flavour and texture of the fudge so try not to take it out completely.
