No Bake Protein Fudge Bars (GF, DF, SF, Vegan)

I had the ingredients for several recipes, but wasn’t sure which one to start. They all sounded good to me! I decided to put it to a vote on Twitter, Facebook, and Instagram. One recipe got an overwhelming majority of the vote across all three platforms: protein fudge bars.

The inspiration for this recipe is from Arman at The Big Man’s World. You may remember him from another chocolate recipe I made around Easter. He has so many recipes that look wonderful, so I picked out a few for us to try.

His recipes are perfect for people like me: few ingredients and simple steps. This recipe calls for four ingredients and takes twelve minutes. See? Perfect.

2 c smooth peanut butter (can use sunflower, cashew, soy nut, or almond butter)

1/2 c maple syrup (can use agave or brown rice syrup)

1 1/2 c gluten free oat flour (can use ground oats)

1/2 c (2 scoops) vanilla protein powder

Optional: chocolate topping

*If using maple or agave syrup, add additional teaspoon


-Place oat flour and vanilla protein powder in mixing bowl

-In a microwave safe bowl or stovetop, combine peanut butter and maple syrup and melt together.
Whisk together until combined.

-Pour into dry mixture and mix together completely.

Pro tip #1: If the mixture is crumbly, add 1 tbsp of water or milk of choice until it’s a thick batter.

-Pour batter into lined 8×8 inch loaf pan or cake tin lined with parchment paper. Press firmly
into place.

-Refrigerate for 20+ minutes until firm. Once slightly firm, add chocolate topping (optional).
Refrigerate for an another 40 minutes.

-Remove and cut into bars.

Pro tip #2: To make this recipe sugar-free, use sugar-free syrup.

Melted Peanut Butter & Maple Syrup
Nikki wanted to just eat the peanut butter & maple syrup mix.

It’s not pretty, but it’s about to be delicious.


Pressed fudge bar mix

We used Smart Balance peanut butter, Bob’s Red Mill Vanilla Protein Powder, Bob’s Red Mill
Gluten-Free Oat Flour, and Miss Jones Organic Chocolate Frosting. As always, these products
are gluten-, soy-, and dairy-free. The frosting is Top 8 Allergen Free.

Note: The Vanilla Protein Powder has chicory root in it. This can cause issues for those on a
low FODMAP diet. We didn’t realize it was in this protein powder when we ordered it. Nikki
found out the hard way & wanted me to warn people following a low FODMAP diet.

For other healthy topping options, check out Arman’s recipe.

Pro tip #3: Don’t use whey protein because the bars won’t form.

Six fudge bars
Our batch made 8 bars, but two weren’t pretty (they were delicious).

So gooey.

Keep bars refrigerated. They can be frozen. If you’d like them extra fudgy, eat them at room

Verdict: these fudge bars are sinfully delicious.

  1. You had me at no bake Sam 😀 Oh my yummiliciousness, these protein fudge bars sound amazing and so easy to make too. I’ll have to try them. Me and baking are not the best of friends, but I think I can do this without messing up.

    • I’m all about no bake! I’m not good at baking either, so this recipe is perfect. It’s so easy and you don’t have to wait to long to eat them. lol Even if you mess up, they’ll still taste good. lol

  2. Oh this sounds great! I am always looking for ways to sneak in more protein so this one is right up my street! I would probably leave the chocolate topping if I was feeling particually well behaved!

  3. Oh wow this is such a great recipe, they look so delicious and I love that they are no bake too, I live for things that are easy to make so this is definitely one to try.
