Guys… I’ve found my new favorite snack. I’ve made them twice already in one week. The second time I made them I had just come in from shoveling our driveway. The snow was literally at my waist. The entrance to our driveway was basically up to my head (I’m only 5’3″, but still) because of the plow trucks coming through. SO MUCH SNOW. But that was definitely my workout for the day. Hence the need for more muffins.I love these muffins for several reasons. They’re quick, don’t require any “odd” ingredients (unless you think baking with protein powder is odd, eerrr), and super satisfying. My goal for these muffins was to keep them gluten-free for the celiac folk, so I busted out the trusty ingredient that is gluten-free oats. In case you didn’t already know, any time a recipe calls for oat flour, you can make your own by grinding down oats into powder. I like to blend a bunch at a time, then put the flour in a labeled container for later. EASY PEASY.

Then of course these muffins also have peanut butter, for the PB lovers. Which if you’re peanut-free, you could also use another natural nut butter, or even sunflower seed butter. The second time around I made these with my sunflower pumpkin seed butter, and added some cinnamon for funsies.

Ummmm guys… My husband literally just asked me if I pollinated our orange tree while he was gone… Um no, no I did not. Why would I think to do such a thing? Apparently we missed the window. I don’t have a green thumb. I’m horrible with plants. The first year we had a garden, I thought the pepper plants were like herbs, and that you should remove the little flower buds. So yeah, I removed the flowers from the pepper plant not actually knowing those would have eventually become peppers. OOPS.

ANYWAYS. Sorry for the derailment. So these Vegan Peanut Butter Protein Muffins then… they’re also sweetened with 1 small mashed banana, and just a 1/4 cup of pure maple syrup. The taste tester husband thought they weren’t quite sweet enough. But of course he has a major sweet tooth. If you think will you miss the extra hint of sweetness, bump up the maple syrup to 1/3 cup.  It shouldn’t really affect your ratios, as its only just about 1 tablespoon more. HOWEVER, if you’re using an unsweetened protein powder, I would recommend adding 1/4 cup of a dry sweetener. Adding more of a liquid sweetener will mess up the rest of the ratios.

One more thing about these muffins! I bake my muffins first at 425F for 5 minutes, then drop the oven temperature down to 375F for the rest of the baking time. This typically allows the muffins to rise higher versus baking them at a steady temperature the entire time. This is something I learned from Sally. These muffins are a bit on the smaller side, so they didn’t get as high as I expected. BUT by baking the muffins this way, they only took 12 minutes total! And they still come out nice and moist.

Servings 9

Ingredients

  • 1 TBS milled flax seed + 3 TBS water
  • 2/3 cup oats, quick or rolled, gluten-free if needed
  • 1 level scoop, about 1/3 cup vanilla (or chocolate) plant protein powder
  • 3/4 tsp baking powder
  • 1/2 tsp baking soda
  • 1/2 tsp salt
  • 1/2 cup natural peanut butter, no oil added preferred
  • 1/2 cup well mashed banana, 1 small-medium
  • 1/4 cup maple syrup, bump up to 1/3 cup if you want muffins a touch sweeter
  • 1/3 cup non-dairy milk, I used unsweetened

Instructions

  • Preheat oven to 425F and line muffin tin, set aside.
  • Start by combining 1 TBS milled flax seed with 3 TBS water, set aside for 5 minutes & allow gel to form.
  • In a small blender, grind up oats into flour. Transfer to small bowl and add protein powder, baking powder, baking soda, & salt. Combine and set aside.
  • In large bowl using paddle attachment of stand mixer, or electric hand mixer, combine peanut butter (make sure it is stirred very well, no oil present), mashed banana, maple syrup, and flax egg. Beat on medium speed until well combined.
  • Add dry ingredients to large bowl and beat on low until almost combined. Add in milk, then using large spatula gently mix together until everything is combined. Batter will be very thick.
  • Using large cookie scoop (makes it easier for dispensing batter) evenly disperse batter into lined muffin tin, about 3/4 full. You should yield 9 muffins.
  • Bake muffins for 5 minutes at 425F. While muffins still in the oven, reduce temperature to 375 and continue baking muffins for 7-8 more minutes*. Check muffins by inserting toothpick into center. Toothpick should come out with little to no crumbs. Allow muffins to cool in pan for 5 minutes before transferring to wire rack to cool completely.
  • Muffins will stay fresh 3-4 days in airtight container at room temperature, or keep in fridge up to one week.
★ Last step! If you make this, please leave a review letting us know how it was!

Recipe Notes:

*Any natural nut butter will work. I tested with sunflower seed butter as well.
*If you want to bake muffins at 375F the whole time, muffins should take approximately 12-15 minutes, but check at 12 with toothpick.
-I do not recommend using whey protein for I’m unsure of how the batter will turn out. If you try it, I’d love to hear how it worked.
-I used NOW Foods Plant Protein Complex.
-Here is a link for the silicone baking cups I used!

    This looks like what I’ve been searching for, everyone at my house loves peanut butter and I’m trying to find ways to get more protein intake for my toddler. Any tips on adapting the recipe to use the mini muffin pan? Little one won’t finish a whole standard size muffin in one sitting…

      Hi Anna, I would bake in mini muffin pan at 350ºF and watch baking time after 10 minutes.

      Hi Phyllis, Sorry to hear you couldn’t see the recipe. The ads should not be *covering* the recipe, but yes, they might be surrounding the recipe instructions. I run ads on my site, as it is one way that helps me provide readers like you with a free recipe (instead of subscription-based website). If you’d rather pay for a subscription service to view recipe, I am open to that feedback. Best, Ashley

      Hi Sue! Glad you like them 🙂 ADding in shredded coconut would be fine – I wouldn’t add more than 1/3 cup as I am not sure if adding any more will affect the batter and the way they bake.

    Cook time was way off for me. Muffins were total mush as instructions were written. Had to bump temp back up to 400° and add almost 10 more minutes

    My centres were mushy but I gave them a few more minutes and they were ok once cooled. I think I would reduce the temp to only 400 next time instead of 375. (finicky oven)

    Just made these!! So good. The recipe was pretty adaptable for me, as I made a bunch of substitutions to use what I had on hand. I used whole wheat flour instead of oat, powdered Pb instead of protein powder, added about a TBS of chia seeds and cacao powder, plus chocolate chips. I had to add some water @ the end to get the consistency right, but it made 12 muffins that rose nicely. Thanks for sharing this recipe!!

    These muffins are SO. GOOD. I’ve made them 4 or 5 times now and each time, they come out moist, delicious and absolutely mouth-watering. I sent a double batch with my husband when he went hunting and he said they stayed fresh for quite a while and gave him great energy. I also made them for my business’ potluck and they got raving reviews! I haven’t experimented with different flavors for funsies yet…but I plan to. Thank you for this great recipe!

    These are great! I used Aria brand protein powder, which seems to be a combination plant/whey powder. All I had to do was cook them a little longer. Will double the recipe next time!

    These muffins are AMAZING! I made them just this morning and they’re already almost gone…maybe I should freeze them next time, or make a double (triple) batch! 🙂 I actually found them a little too sweet–I might kick back the amount of maple syrup next time.

    All in all–delicious, easy to make, ingredients I had on hand. I wish my kitchen smelled like when I was baking these all the time!! These will be a staple in my house for sure!

    I love this recipe! Today is my second time making it! I used the recipe more of a guide more than anything instead of following it as directed as well as doubled it for 18 muffins, so I can freeze half of them for quick snacks. I used quick oats, natural peanut butter, regular eggs, chocolate vegan blend protein mix, almond milk, and added 1/4 cup of cooled, melted coconut oil because I didn’t want them to be dry. I also cooked them on 350°F for 20 minutes only because that is the temperature I use for my other muffin recipes, and lastly, I used my vitamix instead of a mixer.

      Hi Kelsey, Sorry the muffins didn’t quite turn out for you! Not knowing exactly what brand of ingredients you used, it is hard for me to say. It could possibly be the consistency of the peanut butter, or your protein powder. I used as plant protein blend. Did you try the high baking temp first and then dropping down to the 375 as described in the instructions?

      Hi Rosalie! So approximately the macornutrients (with ingredients and brands listed in recipe page) are : 1 muffin – Calories:170 Fat:9 Carbohydrates:16 Sugar:8 Fiber:2 Protein:7

    Peanut butter is my favorite nut butter. I gave it up for a bit because I thought it bothered my stomach but after a while away I can eat it just fine now. I need some of these muffins in my life.

      That would definitely be a bummer if you had to give it up forever! My favorite is cashew now (shocker) but peanut butter has nostalgic memories! Plus it is just a classic. You’d love these muffins 😀
      Thank you Pragati!
