After months of testing different ingredients and amounts, this keto maple walnut fudge recipe has become one of my most requested desserts, even from friends who don’t follow a keto diet.
The hardest part about following a keto diet is usually giving up sweet treats, especially during holidays or special occasions.
That’s exactly why I developed this recipe – to show that you can enjoy rich, creamy fudge while staying in ketosis. The texture is spot on, and the flavor is absolutely amazing.
One thing I really love about this recipe is how it uses simple ingredients that you can easily find or might already have in your keto pantry.
The combination of almond butter and white chocolate creates the perfect base, while the maple extract gives it that authentic maple flavor without adding any sugar.
The addition of collagen protein powder might surprise you, but it’s actually a clever way to make the fudge more nutritious while helping achieve that classic fudge texture.
Plus, the chopped walnuts add a delightful crunch that makes each bite more interesting. Let’s get started!

💡Tips
1. Watch The Heat
When melting the ingredients in the double boiler, keep the water at a very gentle simmer – you should barely see any bubbles.
If the water is boiling too vigorously, the chocolate can overheat and become grainy. Stir constantly while melting, and remove from heat as soon as everything is smooth.
If you see any steam hitting your chocolate mixture, turn down the heat – even a few drops of water can make the chocolate seize up.
2. Cooling The Fudge
The fudge needs time to set properly in the fridge. Don’t rush this step or try to speed it up in the freezer. The gradual cooling in the fridge (1-2 hours) helps develop the right texture.
If you use the freezer, the fudge can develop condensation when you take it out, making the surface wet and sticky. Also, make sure your fridge is at or below 40°F (4°C) for the best results.

FAQ
1. Can I use regular maple syrup instead of maple extract?
No, you shouldn’t use regular maple syrup in this recipe. Maple syrup contains a lot of sugar and carbs that would make this dessert not keto friendly anymore. Maple extract gives you the same delicious maple flavor without any carbs.
2. Can I skip the collagen powder?
The collagen powder plays an important role in this recipe – it helps create the right fudge texture and acts as a binder. Without it, your fudge might be too soft and won’t hold its shape properly.
If you absolutely can’t use collagen powder, you could try unflavored protein powder as a substitute, but the texture might be slightly different.
