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.

    I love this recipe, i just made it for the second time and they are as good as the fist. Definately satisfy your chocolate craving.

    1. Chelsea Lords says:

      I am so happy to hear this! Thank you so much! ๐Ÿ™‚

  3. Chloe says:

    I followed the directions exactly. It tasted too much like oats; the cocoa powder was so overpowering, and it was a bitter, oaty waste. NTM, the muffins stuck to the pan, and I put plenty of oil! Never making these again.

    1. Chelsea Lords says:

      Did you use dutch process or dark cocoa powder?

    These were very good! I doubled the batch and made 12 muffins. The oat flour is so EASY to make. I added and measured the flour then added 3T Chia Seeds and blended again. I omitted the brown sugar but made up for it with applesauce and Greek yogurt. I also reduced the honey by half.

    1. Chelsea Lords says:

      Glad you enjoyed these!

    I was skeptical because Iโ€™ve never used oat flour in a recipe nor did I think that it was enough.
    Even though I added just a little more oat flour and also a little more brown sugar to make up the difference (an extra tablespoon) I donโ€™t think it made to much of a real difference. they actually turned out perfect!! I also used chunky natural peanut butter instead of smooth peanut butter (because thatโ€™s all I had) and I think it was the right call anyways because it adds to the texture beautifully if you are the type to put nuts in your brownies like me. Thank you ๐Ÿ™‚ Iโ€™ll definitely make it again

    1. Chelsea Lords says:

      Glad you enjoyed these muffins!!

  6. Katie says:

    I was wondering if anyone tried a vegan version of this? My family has issues with yoghurt and egg too. I will give it a go with vegan yoghurt and egg replacer, I think
