Chocolate Peanut Butter Muffins

These muffins are amazing! They call for healthier ingredients and require very little sugar, compared with most muffins (like these Chocolate Muffins!). Plus, there is no wheat flour used. If you’re gluten intolerant, you’ll appreciate the absence of wheat flour!

One of my favorite things about these muffins is that there are no strange ingredients that you probably wouldn’t have on hand or know exactly where they are in your grocery store. Often, healthy muffin recipes call for specialty flours, oil, or sweeteners, and my goal is to use easily accessible mainstream ingredients. And — of course — at no sacrifice to flavor!

Making oat flour by placing oats in the blender and processing them until they are pulverized into flour.

I mentioned that Chocolate Peanut Butter Muffins are flourless; instead of using white flour, or even whole wheat flour, we use oats. The oats are blended into a powdery oat flour. No need to buy this from the store, since it literally takes seconds to make at home.

How to make oat “flour”

  1. Place old-fashioned or quick oats in a food processor or small blender jar.
  2. Pulse the oats until they are ground into a powder-like consistency that resembles flour (see photo above on the right).
  3. Stir the oats around to be sure that all the oats have been finely ground.
  4. Measure the oat flour for these muffins after it’s been turned to flour and not in the original whole oat form. Two tablespoons isn’t a lot, but contributes to the overall stability and flavor of these muffins.

Combining the dry ingredients with the wet ingredients, then pouring the batter into prepared muffin tins, baking, and preparing to enjoy.

Chocolate Peanut Butter Muffin ingredients

  • Cocoa powder: Use natural cocoa powder, not a Dutch-process cocoa powder. I’ve tested these muffins with Dutch-process cocoa powder, and it does not work in these muffins!
  • Oat flour. More on this in the section above.
  • Baking soda, baking powder, salt. These baking agents help ensure a nice crumb and rise. Here’s how to make sure your baking soda and powder are fresh.
  • Creamy peanut butter. Make sure to use creamy, not chunky, peanut butter in these muffins. If using natural peanut butter, be sure it is well mixed and incorporated (not separated or overly oily) before adding.
  • Unsweetened applesauce. If using sweetened applesauce, you’ll want to reduce the amount of brown sugar.
  • Vanilla Greek yogurt. Our favorite yogurt to use in these muffins is Honey Vanilla Greek yogurt (made by Greek Gods® — not sponsored). Whatever yogurt you choose to use, make sure you like it plain or you likely won’t love it in these muffins.
  • Vanilla extract. Vanilla adds a nice flavor to the muffins. It’s not entirely necessary, so don’t worry if you don’t have any to add.
  • Brown sugar. This recipe only uses 2 tablespoons, but if you aren’t used to healthier baked goods, you may want to increase the brown sugar to 4 tablespoons.
  • Honey. This natural sweetener adds additional sweetness. The reason we use part honey and part brown sugar is because too much honey makes these muffins too moist.
  • Egg. These muffins need one large egg; I have not personally tested using egg alternatives.
  • Dark chocolate chips: To keep these Chocolate Peanut Butter Muffins more on the nutritious side, we’re using dark chocolate. Dark chocolate has essential fats your body needs and is a powerful source of antioxidants. (Source.)

Quick Tip

If you are eating a gluten-free diet, these muffins are a great addition! While no gluten is added to this recipe, be careful to read the labels on the baking products you buy. Some contain gluten where you wouldn’t expect it, and others are made in a facility with gluten and may be exposed to cross-contamination with gluten products.

Tips

  • Generously grease the muffin tin. I don’t recommend muffin liners in this recipe; the batter sticks to the liners. Make sure to really grease the cavities well. Of course, a good muffin tin also makes a world of difference. These tins are my absolute favorite, and I’ve never had a problem with these muffins not releasing nicely.
  • Add a few dark chocolate chips on top. I like to add three or four extra chocolate chips on top of each muffin before putting them into the oven. Not only does this make the tops look nicer, it also ensures there is a chocolate chip in every bite!

Recipe Notes

Note 1: To make your own oat flour, place old-fashioned or quick oats in a food processor or small blender jar. Pulse the oats until they are ground into a powder-like consistency that resembles flour.
Note 2: If desired, you can use just applesauce or just Greek yogurt instead of a combination of both, but make sure to still use 1/2 cup measurement of whichever you choose to use.
Storage: Store peanut butter muffins in an airtight container at room temperature for 3 days or refrigerate for up to a week.
For longer storage, wrap and freeze for up to 3 months. Thaw at room temp or microwave briefly to warm.

    These are absolutely delicious Chelsea. I knew by looking at the ingredients that this would be a keeper. The 1st time I made a double batch and they were gone in 24 hours. A few days later, I made a triple batch, gone in 36 hours. My adult sons gobble them up for breakfast and mid morning snack at work. My one son, who unfortunately does not eat very healthy, actually asked me to make them again just 2 days later! Thank you!

    Hey Chelsea,
    I made your healthy choc chip cookies and can i just say they were beyond amazing. Everyone in my house, even the junk food lovers were pleased. THANK YOU! I will make the brownies tonight. Super excited

    I have to admit I had very little hope that these would actually be good. But they are FANTASTIC. My picky kids LOVE these. I have no guilt about them eating these muffins! Thanks for this recipe. We will use it again and again.

    1. chelseamessyapron says:

      YAY!! I’m so happy that you and your kids loved these muffins ๐Ÿ™‚ I’m thrilled it was a hit! Thanks Josie!

    These are AMAZING!!! I have made them several times now and they are now a staple in our house! Not only do we love them, but I like to take them as dessert when we go places and people rave about them! I use coconut sugar instead of brown, but other than that I follow the recipe exactly ๐Ÿ™‚ thank you for this fabulous recipe!

    1. chelseamessyapron says:

      Hi MacKenzie, thank you so much for the comment! ๐Ÿ™‚ I am so thrilled this recipe has been so well enjoyed! ๐Ÿ™‚

    I followed exactly, and doubled the recipe… but mine burnt long before the time ๐Ÿ™ I have a true convection oven, but did not put it on convection bake… Otherwise nice and fluffly but burnt before 10 minutes on the reduced heat… Will have to adjust the next time!

    1. chelseamessyapron says:

      Oh bummer!! I hope you get a chance to enjoy these next time with an adjusted time! ๐Ÿ™‚

    Hi Chelsea, I did everything correctly as in the recipe and my muffins did not rise, also can I just ask
    is 2 tablespoons of blended oats the correct measure? as it does not seem alot to me (was it a misprint)
    or just my bad baking lol!!!, anyway they taste okay will probably have them with custard.

    1. chelseamessyapron says:

      Hey Lesley, I’m sorry to hear that! I haven’t ever heard that and gotten lots of reviews for this recipe. The 2 tbsp.s is correct ๐Ÿ™‚ Are your baking agents fresh? Was the oven fully preheated before putting the muffins in? Did you overbeat the mixture? These muffins don’t rise a ton like a typical bakery style muffin, but they shouldn’t be flat at all ๐Ÿ™‚

      1. Cindy says:

        Mine didn’t rise either. I just opened a new baking powder. I tested my baking soda with vinegar and it’s still good. My oven was preheated, and I don’t think I overmixed it.

        1. chelseamessyapron says:

          They don’t rise a whole ton as you can see from the pictures and video…did they look different from pictures/video?

  7. Lisa says:

    Are these mini muffins?

    1. chelseamessyapron says:

      Nope ๐Ÿ™‚ Regular sized!

    Did you really mean 2TBS of oat flour and that’s all? I’m making them tonight, but would love to know if I read it right. I love your pumpkin/oatmeal/chocolate chip muffins. I’ve quadrupled the recipe and keep them in the freezer.
    No canned pumpkin puree this time of year, so I’ll try something else. Thanks

  9. Derrick says:

    Any idea how his would turn out if you doubled the recipe and baked in a loaf pan, say at 350F for an hour?

    1. chelseamessyapron says:

      I don’t believe it would turn out in a loaf pan. I haven’t had much success with “flourless”recipes in a loaf pan, they typically burn around the edges and are gooey in the middle.

  10. Natalie says:

    These muffins are Amaaaaazing! We can’t seem to keep these for longer than a day. They just vanish! They are so delicious and decadent thank you:)
