Peanut Butter Protein Loaf
This peanut butter protein loaf has over 16g of protein per slice! This was one of those happy accident recipes that I am so pleased I stumbled upon. You could slice it, toast it, and have it with jam, use it for a PB&J, or if you wanted to get wild, use it as a base for peanut butter French toast. I am telling you, make this one!

Peanut Butter Protein Loaf- Baking with Protein Powder.
If you’re like me, getting a few extra grams of protein is an important thing. I have a bit of a sweet tooth too, and this Peanut Butter Protein Loaf is perfect for both!
Protein powder is a great additive to any baking recipes, but in small quantities. You wouldn’t want to replace all of the flour with protein powder, as many recipes still depend on the natural gluten found in flour.
This loaf is that perfect balance of dense and rich, while still being light enough to enjoy regularly.

Peanut Butter Protein Loaf- Making it right.
This is a super easy recipe; all you need is two mixing bowls and a few ingredients. The key here is to properly mix your leavening agents (baking powder and baking soda) so that you get a proper rise on your loaf.
There are some pretty heavy ingredients in this recipe that, if not incorporated properly, will turn it from nice and light to heavy and not so nice!
When you mix your dry ingredients, take a few extra seconds and properly mix everything together. It may look like everything is mixed, but there could be pockets of baking soda or powder that won’t be distributed properly.

A little yogurt goes a long way.
Like we said above, there are a few heavy ingredients in this recipe: eggs, peanut butter, maple syrup, and yogurt. But can you guess which one actually brightens up the finished loaf?
If you guessed Greek yogurt, you’re right!
Greek yogurt has a ton of beautiful, natural sour acidity that, when added to a ton of baked goods, can brighten the whole thing up. Greek yogurt is also a fantastic source of protein as well!

OMG!! You never disappoint!!! I was a little skeptical about the PB powder, and PB. I thought it was going to taste like a peanut butter cake. Thankfully, it did not!! Just deliciously sweet. Love this!! Thank you!!
So glad you loved it, MJ! Happy to hear the peanut butter flavor hit just right without being overpowering. Thanks for giving it a try!
I just made this bread and it’s fantastic. I love the yogurt and protein powder to give that boost of protein in each slice.
Thanks so much for the recipe.
You’re so very welcome, Beth! Thanks for trying it and sharing your feedback!
I am unable to find peanut butter powder. Can peanut butter be a replacement? If so, how much would the 3/4 cup powder be replaced with? Thanks!
Hi Deb! You can swap in regular peanut butter—I’d use about 1 ½ cups in place of the ¾ cup peanut butter powder. Just note the texture will be a bit denser and more moist.
I’ve made this about 20 times. Super yummy!
It’s that good, I agree Jenn! Thanks for sharing!
Awesome! Easy delicious and high protein ta boot. Substituted almond flour and it’s fantastic. Curious to figure out nutritional details. Will be a staple
