These vegan, gluten-free chunky monkey muffins are made in one bowl! Made with oat flour, peanut butter, bananas, chocolate chips, and nuts, these one-bowl, oil-free muffins are a healthy snack option.
The combination of ingredients that comprises the beloved Ben and Jerry’s “Chunky Monkey” flavour–chocolate, bananas, and nuts–has got to be one of man’s better inventions. And if you’re anything like me, you probably spend your days conjuring up ways to eat more chocolate, bananas, and nuts, independent of ice cream! It was during one such daydream that I came up with the inspiration to make chunky monkey muffins! It wasn’t all that difficult, since I was able to use my One Bowl Vegan Banana Peanut Butter Blueberry Muffins as a blueprint. I just made a few swaps and the result was these vegan and gluten-free chunky monkey muffins! You need these in your life: They make the most incredible afternoon snack or healthy dessert. I’ve even been known to enjoy them for breakfast!
Chunky Monkey Muffin Ingredients
- Ground flax, overripe bananas, coconut sugar, peanut butter, almond milk, vanilla extract, baking soda, baking powder, sea salt, oat flour, chocolate chips, chopped walnuts or pecans, and rolled oats.
Step By Step Instructions
- Mix up a flax egg in a large bowl. Once thickened, add mashed bananas, coconut sugar, peanut butter, almond milk, and vanilla. Whisk to combine. Next, add the baking soda, baking powder, and salt, whisking after each ingredient addition. Finally, stir in the oat flour, then fold in the chocolate chips, chopped nuts, and rolled oats!
- Transfer into lightly greased muffin tins and bake at 350 degrees F for 18-22 minutes, or until a tester inserted into the middle comes out clean.
- Let the muffins cool for 15 minutes in the pan before transferring to a wire rack to cool completely.
- Store the muffins in an airtight container at room temperature for a few days or in the refrigerator for a week or more. You can also freeze them for several weeks.
Ingredient Substitutions
- If you have nut allergies, substitute an equivalent amount of tahini for the peanut butter (just make sure that the tahini is nice and runny). Omit the nuts or replace them with sunflower seeds. If you have a peanut allergy but you can eat other nuts, use almond butter or cashew butter instead of peanut butter.
- If you don’t have any oat flour, either make some in your food processor or use spelt or whole wheat flour. You may need to add a bit more liquid if you use wheat flour.

I bake a match of healthy muffins as a quick grab-and-go snack nearly every week, so I’m always on the lookout for new ideas. I’ll have to try these muffins soon!
Allison says
I love doing that, too! 🙂 Hope you enjoy them, Nicole!
Julie says
These are so good! Can’t believe how moist they came out without any added oil. And love the peanut butter flavour. My kids and I gobbled up the whole batch in less than two days- oops! Guess we’ll have to make more when we have ripe bananas again.
Allison says
Aw, thank you, Julie! So glad you and your kids enjoyed. 🙂
Daria says
If I was able to give this recipe more than 5 stars I would!! One of my families favourite muffin recipes, I make them weekly.
I make them as mini muffins for my grandkids and I’ve made them with dates in place of sugar for my hubby who doesn’t eat sugar. Every time they turn out awesome, so moist and full of flavour ? I tend to fill my muffin tin high so I usually only get 9 muffins but I get 24 minis.
Looking forward to try more recipes from Allison.
Allison says
Thank you so much for leaving such a nice comment, Daria! I’m so, so happy that you and your family love these muffins. 🙂
Homeschool Mom says
These are delicious! I’ve made a couple of your recipes now. I’ll admit that after I let the flax egg gel, I dump in all the rest of the ingredients through the flour, and then stir by hand. I fold in the mix-ins like chocolate and nuts afterword. They’ve come out great and had excellent texture. I’m looking forward to trying more of your recipes!
Allison says
Thank you, that’s so great to hear! I’m glad that you enjoyed these muffins!
