Tender, flavorful, and packed with protein, these fluffy Peanut Butter Muffins can have any add-in your family likes, and they store well for days (or longer in the freezer). They’re great to prep ahead and enjoy all week.
I started making muffins with a dose of peanut butter when my middle kiddo was a baby. She struggled with bread-y textures—they were just difficult for her to eat for months and months—and the muffins turned out to have the perfect amount of moisture for her.
Since then, I’ve tweaked and tested this recipe for Peanut Butter Muffins that is as versatile as it is delish.
These muffins for kids (or adults) are great on their own for breakfast or snack, or you can top them with butter and/or honey. You can choose one add-in for the whole batch or do a mixed batch to please everyone. And they work as full-size or mini muffins.
There are so many options so you can make them with your family in mind. They are a satisfying toddler breakfast, an easy Meal Prep Breakfast option, and an easy Summer Lunch for Kids to pack on the go.

Ingredients You Need
Here’s a look at what you’ll need to make these Peanut Butter Muffins so you know what to have on hand or pick up from the store.
- Whole wheat flour: I use a base of whole wheat flour, but there’s an option of using all-purpose. See the Notes at the end of the recipe for specifics.
- Baking powder and baking soda: These help the muffins rise nicely.
- Smooth peanut butter: I use natural-style creamy unsweetened peanut butter, usually a store brand or Smucker’s Natural.
- Milk: I typically cook and bake with whole milk, but any nondairy milk would work here, too.
- Applesauce: This adds flavor, some sweetness, and moisture. I use store bought unsweetened applesauce or homemade applesauce. If you are out of applesauce or don’t have access to it, you can use mashed banana or Banana Puree.
- Sugar: I add a little sugar, which when paired with the optional add-ins, provides nice flavor. (Or, as an alternative, you can use maple syrup.)
- Eggs: Large eggs help the batter to hold together nicely and bake up with a tender crumb.
- Vanilla extract: Vanilla enhances the flavor of the peanut butter, making the flavors even more delicious.
- Optional add-Ins (choose one or do a mixed batch): Chocolate chips, finely diced strawberries, finely diced apple, white chocolate chips, blueberries, or diced banana.
Step-by-Step Instructions
Here’s a look at how to make these Peanut Butter Muffins so you know what to expect from the process. Scroll down to the end of the post for the full information and amounts.
Step 1. Stir the wet ingredients together in a medium bowl. Add the dry ingredients. Gently stir together.
Step 2. Stir in your desired add-in. (Or you can plan to add it on top of each muffin if doing a mixed batch.) Divide the batter among a greased muffin pan.
Step 3. Press the add-ins into the batter if you didn’t stir your add-ins into the batter or you’re doing a mixed batch.
Step 4. Bake muffins until firm to the touch and lightly golden brown around the edges.
TIP: To make these as mini muffins, reduce the baking time by about 4 minutes.
Frequently Asked Questions
Gently stirring the batter, baking the recommended time until a toothpick or cake tester inserted into the center comes out cleanly, and transferring baked muffins to a wire rack to cool fully helps create moist muffins.
I prefer to use creamy unsweetened peanut butter in baking.
You can make this recipe as standard or mini muffins to make a lightly sweet, tender toddler muffin.

How to Store
Once cooled, store Peanut Butter Muffins in an airtight container for up to 3 days at room temperature. Store in the fridge in an airtight container for up to 5 days.
Warm slightly to serve from the fridge (they firm up a bit when they’re cold so warming slightly returns them to their softer texture) if you prefer.
You can also freeze the muffins in a freezer bag with as much air removed as possible for up to 3 months. Thaw at room temperature or in 15-second increments in the microwave.
Best Tips for Success
- Use one add-in per batch of Peanut Butter Muffins, or use 1 tablespoon of each to make a mixed batch.
- Gluten-free: Substitute cup-for-cup all purpose gluten-free flour in place of the wheat flour.
- Egg-free: Omit the egg. Add ½ cup milk. Proceed with the recipe.
- Dice up muffins as needed for younger eaters.
- Top with butter, nut butter, or jam as desired, or serve with diced fruit, a toddler smoothie, or another easy food.
- Sub almond butter or sunflower seed butter if desired to make peanut-free muffins.

Would these work with almond butter as well?
Yes, if it’s the same consistency as peanut butter and not super runny, it should work well.
Haven’t made yet however they look yummy! Any way to add some fiber to this recipe? Thank hoi
There is 3 grams of fiber per muffin already. You could use the berry option and stir them into the batter for more.
Can you use regular smooth (sweetened) peanut butter? Would I omit the extra sugar if so?
Sorry didn’t mean to give it a rating! I haven’t tried them yet lol.
Has anyone tried this with powdered PB? That’s all I have at the moment.
It usually has directions on the package to turn it back into regular peanut butter by mixing with water, so I would do that to make 1 cup of peanut butter and then use it in the recipe. (Or add the amounts of the powder and water to the batter.) My best guess is that it will work fine. It may be a little less moist since powdered peanut butter sometimes has some of the fat taken out. Let mek now if you try it!
What would you do if the muffins need to be GF, DF, and Egg free? Would you just sub 1/2 c more milk alternative?
I would use a cup for cup style of gluten free flour blend, use non dairy milk and yes, that egg replacer option listed in the Notes or your favorite store-bought egg replacer like the one from Bobs Red Mill.
These are so good! Both my kids love them. Make them today; you won’t be disappointed.
Can these be made with sun butter?
They can!
Will the recipe work if I use Sunflower butter??
It will!
Delicious! Followed the exact recipe – I used banana as an add-in and they are so good. Thanks Amy!!!
My daughter loved these muffins! I added dark chocolate chips as my add-in. Thanks for this recipe!
Can all-purpose flour be substituted for whole wheat flour if I don’t have it? Same measurement?
Yes, they just may need 2-4 minutes more of baking time
Hi! Milk is in the ingredient list but not the recipe steps? Could you please clarify?
Hi- You add it in Step 3: In another bowl, stir together the peanut butter, milk, applesauce, eggs, and vanilla. (I updated it last night and it’s showing on desktop but not mobile for everyone, so maybe try to clear your cache. Sorry about that!)
Thank you so much! That’s what I ended up doing and they were SO yummy! I thought I was going crazy because the directions weren’t there (when I commented), then they were, and then later they were gone again. 😅 Thank you for your response and for this great recipe!
I added some extra sugar and subbed banana for apple sauce, and it came out great!! Thanks for the new recipe- likely will be in our rotation 😀
So fluffy and good! I made them as minis with cranberries 🙂
Every thing I’ve tried has been amazing! So excited to try more!
