I don’t know about you, but when we have a brownie, we want the brownie to be fudgy, moist, and still warm when we eat it. These flourless peanut butter protein brownies use cocoa powder and protein powder in place of flour and have pockets of fudgy melted chocolate in every bite.

What is in protein brownies?

Make sure to scroll all the way down to the recipe card to get the full ingredient list and written recipe.

These flourless peanut butter protein brownies get their added protein from protein powder and peanut butter. Each brownie has 12g of added protein per brownie.

The high protein ingredients are accompanied by classic brownie ingredients like brown sugar, eggs, chocolate chips, and baking powder.

Substitues & Variations

  • The bake time may vary depending on the oven, what pan is used, and whether or not you are baking at altitude.
  • If you know one side of your oven bakes hotter than the other, turn the baking pan in the oven halfway through the baking time.
  • Feel free to add other delicious brownie mix-ins.
  • We highly recommend serving these brownies warm with a scoop of ice cream or protein ice cream.

Storage

Let these brownies cool completely before slicing them into squares and storing them in an air-tight container for 3-5 days. If you don’t let the brownies cool before storing them, they will become moist.

Freezer Directions

Let the brownies cool and then store them in a freezer-safe container. Freeze them for up to 3 months.

Ingredients 

Dry

Wet

  • 1 cup unsalted all-natural peanut butter, drippy
  • ½ cup maple syrup
  • 3 tablespoons packed brown sugar
  • 1 teaspoon vanilla extract
  • 2 large eggs
  • ½ cup plain, unsweetened almond milk*
  • ½ cup chocolate chips, melted
  • 3 tablespoons melted coconut oil

Instructions 

  • Preheat the oven to 350ºF and line a light-colored 8×8-inch pan with parchment paper.
  • Add all of the dry ingredients into a mixing bowl and mix to combine. Set aside.
    A bowl with cocoa powder and a whisk.
  • Next, cream the peanut butter, maple syrup, brown sugar, and vanilla together and mix until combined and smooth.

  • Add the eggs and almond milk and stir to combine.
  • Add the dry ingredients to the wet and mix until well combined. Add the coconut oil and stir again.
  • Fold the melted chocolate into the batter. Do not over-mix the melted chocolate in so it is combined with the batter, fold it in so there are fudgy pockets throughout the batter.
  • Transfer the batter into the line-caked pan. Option to top the batter with more chocolate chips.

  • Bake the brownies for 35-40 minutes or until the center of the brownies is almost baked. You want there to be a little bit on the toothpick when you check the middle of the brownie as the brownie will continue to cook when it is removed from the oven.
  • Allow the brownies to cool for 3-5 minutes before gently loosening the sides of the brownie with a knife and then lifting the parchment paper. Transfer the brownies to a cooling rack.

Unbelievably good! I can’t believe they do not have any flour in them. As others have said, they are more cakes than gooey but if you eat them straight out of the oven they are fabulous. We almost ate the entire pan in one sitting.

These turned out super tasty! Dense, moist & cakey! I agree with previous comments that ice cream would pair really well with these.

I ended up using vanilla whey protein powder and adding an extra tbsp of cocoa powder, and subbed light olive oil for coconut oil. I baked them for 30 mins in hopes they’d be fudge-y but they were still cake-y and rose quite a bit. I think that just may be what it is with this type of recipe? I’m guessing they’ll be slightly fudgier tomorrow after they cool and collapse a bit. Tasty recipe tho!

I have celiac so these were a great high protein and gluten free treat- I swapped out the coconut oil for applesauce- still perfectly moist and the right amount of gooey!

I really liked these brownies. They were thick, moist and chocolatey. They taste great with a little ice cream and no guilt.

So fudgy and delishhhh! I like the gooey type brownies so this did the trick for me. Flavor depended on the cocoa powder, so I would splurge for the good stuff if you can find it!
