No Bake Oat Fudge Bars (Vegan Protein Bar)

Evann Ryan

These one bowl, easy, no bake oat fudge bars are loaded with peanut butter flavour and 18g of protein PER square! I wrestled with what to call them as the macros suggest protein bar all the way, but the creative thinking came from making a copycat Starbucks Oat Fudge Bar. However to offer a few options, one being more like a Starbucks dupe with less protein and more healthy fats, and a second option that's absolutely loaded with protein. Both options will be listed, with their macros, for you below.

Now, if you're looking for some healthier, homemade protein bars, then the protein version of these made with peanut butter powder instead of full fat peanut butter is going to be for you. In fact they're still packing some good fats from the soy milk (or your preferred nut milk) and the high quality chocolate, while also being your macro bestie.

What You'll Need To Make These Oat Fudge Bars

Peanut butter powder or full fat peanut butter. While the protein bar version uses peanut butter powder, the sweet treat version uses full fat peanut butter.

Sprouted oats or regular oats, blended into a flour. You can also just use oat flour. 

Vanilla protein powder. I like Vedge Nutrition best. Their protein powder is gluten free, non-GMO, third party tested, and its a really fine powder that seamlessly blends into everything! You can shop their protein (and vegan supps!) using my discount code: EVANNRYAN.

Maple syrup, or your preferred liquid sweetener. This adds a little sweetness, but it also makes the batter sticky enough to hold together.

Soy milk, or your preferred dairy free milk. 

Sea salt. Because all sweet treats needs a touch of salt to pick them up!

Chocolate. My personal preference is using Zazubean or Enjoy Life for vegan chocolate options. Zazubean offers sugar free, low sugar options. Enjoy Life is a simple vegan chocolate chip with minimal ingredients.

 

Step one: add the peanut butter (made from pb fit or regular) to the bowl.

Step Two: Add the dry ingredients.

Step Three: Add the wet ingredients.

Substitutions

You can skip the protein powder and use more oat flour. Just add in small amounts of extra oat flour at a time until you reach a dough like consistency.

If you're going to the full fat peanut butter route, you can substitute any nut or seed butter. 

 

Step Four: Press the dough into the pan, and cover in melted chocolate ganache.

Step Five: Spread the chocolate ganache evenly from edge to edge.
