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.
Peanut Butter Muffins
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 be the perfect amount of moisture for her.
Since then, I’ve tweaked and tested the recipe for one that is as versatile as it is delish.
These muffins 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.
So many options so you can make them with your family in mind.

Ingredients You Need
Here’s a look at what you’ll need to make this muffin recipe 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 muffins so you know what to expect from the process. Scroll down to the end of the post for the full information and amounts.
- Stir the wet ingredients together in a medium bowl.vAdd the dry ingredients. Gently stir together.
- Stir in your desired add-in. (Or you can plan to add it on top of each if doing a mixed batch.) Divide the batter among a greased muffin pan.
- Press the add-ins into the batter if adding a mix to the batch.
- Bake 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.

How to Store
Once cooled, store 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).
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 muffin, or use 1 tablespoon of each to make a mixed batch.
- Gluten-free: Substitute cup-for-cup gluten-free flour in place of the wheat flour.
- Egg-free: Omit the egg. Add ½ cup milk. Proceed with the recipe.
- Dice up as needed for younger eaters.
- Top with butter, nut butter, or jam as desired.
- Sub almond butter or sunflower seed butter if desired.

These are amazing! I didn’t have applesauce so I used mashed banana (1/4 cup) and was short on chocolate chips, so I used a 1/2 cup of mini chips instead of 1 whole cup. There were perfect! We took them outside and shared with all the neighbors. I’m sad they are all gone, but glad we could share haha! Will make them again!
I love this recipe. It is like a peanut butter cookie in muffin form. So yummy and moist! They do not last long at my house.
So delish! My toddler also struggles with bready textures and she loves these. Your recipes are wonderful, I’m so thankful for you and the work you do!
I’m so glad to hear that and you’re so welcome!
Love your website! Could mashed banana be used instead of maple syrup or sugar and if so how much?
I haven’t tried that but I would use 1/4 cup and know it may take a minute or two longer than the time I say to bake through.
My 2.5 yo and I made these last night. It was perfect! Recipe is easy to follow (we made as is in the mini muffin pan) and plenty for the little guy to do. We had a great time making these together. He chose chocolate chips to mix-in and they were obviously delicious! We served a few with dinner and will use the rest for breakfast/lunches during the week.
I’m glad to hear that!
