Peanut Butter Muffins

Soft, fluffy peanut butter muffins studded with chocolate chips that taste like your favorite candy bar in breakfast form. Ready in under 30 minutes!

There’s something magical about biting into a warm peanut butter muffin with melty chocolate chips that just makes everything better. I’ve been making these since my college days when I needed something quick, delicious, and way better than the vending machine—and honestly, they’re still my go-to whenever I need a little pick-me-up.

Why You’ll Love These Peanut Butter Muffins

These aren’t your average muffins, my friend. They’re tender, moist, and packed with that rich peanut butter flavor you crave. The chocolate chips? They’re basically mandatory. You get that perfect balance of sweet and salty, soft and melty, and they’re ridiculously easy to whip up. No fancy equipment needed—just two bowls and a whisk.

Ingredients You’ll Need

Ingredients for Peanut Butter Muffins

Here’s what you’re grabbing from the pantry. Nothing weird or hard to find, I promise.

Dry Ingredients Wet Ingredients Mix-Ins
1 3/4 cups all-purpose flour (219 grams) 1/2 cup vegetable oil (120 ml), or canola 1 cup chocolate chips (180 grams)
2 teaspoons baking powder 3/4 cup light brown sugar (158 grams)
1/4 teaspoon salt 3/4 cup peanut butter (do NOT use natural)
2 large eggs, room temperature
2 teaspoons vanilla extract
1 cup buttermilk (240 ml), room temperature

Quick note on the peanut butter—stick with the regular creamy stuff like Jif or Skippy. Natural peanut butter will make these too oily and dense. Trust me on this one.

How to Make Perfect Peanut Butter Muffins

Getting Started

First things first: preheat your oven to 375°F (190°C). Line a regular muffin pan with those cute paper liners. You’re going to end up with 12-14 gorgeous muffins depending on how generous you are with the batter.

Prep Your Dry Ingredients

Grab a large bowl and whisk together your flour, baking powder, and salt. Give it a good mix so everything’s evenly distributed. Set this aside—you’ll come back to it in a minute.

Mix the Wet Ingredients

Here’s a little trick I learned the hard way: warm up your peanut butter in the microwave for about 30 seconds on medium power. It makes everything SO much easier to mix. In another large bowl, whisk together the oil, brown sugar, and that slightly softened peanut butter until it’s smooth and dreamy.

Combine Everything

Now whisk in your eggs, vanilla, and buttermilk to that peanut butter mixture. Keep whisking until it’s completely smooth and well combined. The smell alone is going to make you want to skip straight to dessert.

Make a little well in the center of your dry ingredients—kind of like a volcano situation. Pour the wet ingredients right into that well. Here’s where patience pays off: gently fold everything together. Don’t overmix! A few small lumps are totally fine, but if you’ve got big clumps of flour hanging around, use a wire whisk to break them up gently.

Add the Chocolate

Fold in about 3/4 cup of those chocolate chips. Save the rest for topping because presentation matters, even on a Tuesday morning. The batter should be thick but pourable—kind of like a really luxurious cake batter.

Preparing Peanut Butter Muffins

Fill and Top

Spoon the batter into your prepared muffin cups, filling each about 3/4 full. Don’t be shy, but don’t overfill either or you’ll get those weird mushroom-top muffins. Sprinkle the remaining chocolate chips on top of each unbaked muffin. This is what makes them look bakery-worthy.

Bake to Perfection

Pop them in the middle rack of your preheated oven and bake for 16-18 minutes. You’ll know they’re done when a toothpick inserted in the center comes out clean—well, except for the melted chocolate chips, obviously. Your kitchen is going to smell absolutely incredible right about now.

Let the muffins cool in the pan for about 10 minutes. This is important because they’re super tender when hot. Then carefully transfer them to a wire rack to finish cooling. Or, you know, eat one immediately and burn your mouth like I always do.

Expert Tips for Bakery-Style Results

Room temperature ingredients matter. Cold eggs and buttermilk won’t incorporate as smoothly, and you might end up with dense muffins. Let them sit out for 30 minutes before you start, or put the eggs in warm water for 5 minutes.

Don’t skip the peanut butter warm-up. Seriously, those 30 seconds in the microwave save you so much arm strength. Cold peanut butter is a nightmare to whisk.

Use the toothpick test wisely. Since there are chocolate chips in these peanut butter cup muffins, your toothpick might have some melted chocolate on it. That’s fine! You’re looking for wet batter, not gooey chocolate.

Size matters. If you want jumbo muffins, use a jumbo pan and increase the baking time to 22-25 minutes. For mini muffins, reduce the time to 10-12 minutes. Adjust accordingly and watch them closely.

Amazing Variations to Try

Peanut Butter Oatmeal Chocolate Chip Muffins

Want to add some texture and make these feel a tiny bit healthier? Replace 1/2 cup of the flour with old-fashioned oats. You’ll get these lovely little pockets of chewiness throughout. It’s one of my favorite ways to jazz up this recipe.

Extra Nutty Version

Throw in 1/2 cup of chopped peanuts or pecans along with the chocolate chips. The crunch factor is unreal, and it makes them feel extra special.

Swirl It Up

Before baking, add a teaspoon of jam (strawberry or raspberry works great) or Nutella to the top of each muffin and swirl it with a toothpick. Game changer.

Make Them Gluten-Free

Use a 1:1 gluten-free flour blend instead of all-purpose flour. I’ve tested this with Bob’s Red Mill and King Arthur, and both work beautifully. These muffin recipes peanut butter adapt really well.

Troubleshooting Common Issues

Muffins came out dry? You probably overbaked them or overmixed the batter. Check them at 16 minutes, and remember to fold gently—you’re not making meringue here.

Tops didn’t brown? Your oven might run cool. Try increasing the temperature by 25°F next time, or bake them a couple minutes longer.

Muffins stuck to the pan? Always use muffin liners or grease your pan really well. Non-stick spray is your friend.

They taste too dense? Make sure your baking powder is fresh (check the expiration date) and that you’re not packing the flour when you measure. Spoon it into the measuring cup and level it off.

Storage and Reheating

Keep these muffins fresh and delicious with proper storage. Here’s your cheat sheet:

Storage Method Duration Best For
Room temperature (airtight container) 2-3 days Immediate enjoyment
Refrigerator (airtight container) Up to 1 week Meal prep
Freezer (freezer bag or container) Up to 3 months Long-term storage

Reheating tips: Pop a muffin in the microwave for 15-20 seconds to get that fresh-baked warmth. If you’re reheating from frozen, microwave for 30-45 seconds. You can also warm them in a 300°F oven for 5-7 minutes if you’re doing a bunch at once.

No-waste kitchen hack: Crumble up any muffins that went a bit stale and use them as a topping for yogurt or ice cream. Or make a quick trifle by layering muffin pieces with whipped cream and sliced bananas. Nothing goes to waste!

Peanut Butter Muffins FAQs

Can I use natural peanut butter instead of regular?

I really don’t recommend it. Natural peanut butter has way more oil and will throw off the texture completely. You’ll end up with greasy, dense muffins instead of fluffy ones. Stick with Jif, Skippy, or similar brands that have a thicker, more stable consistency.

What can I substitute for buttermilk?

No buttermilk? No problem. Mix 1 cup of regular milk with 1 tablespoon of lemon juice or white vinegar. Let it sit for 5 minutes until it gets slightly thick and tangy. Works like a charm every single time.

Can I make these egg-free?

You can try using flax eggs (2 tablespoons ground flaxseed mixed with 6 tablespoons water, let sit 5 minutes). I haven’t personally tested this variation, but readers have had success. The texture might be slightly different.

How do I know when they’re actually done?

Insert a toothpick into the center of a muffin. It should come out clean or with just a few dry crumbs—melted chocolate doesn’t count! If you see wet batter, give them another 2 minutes.

Time to Bake!

These peanut butter muffins are seriously one of the easiest, most crowd-pleasing recipes you’ll ever make. Whether you’re meal-prepping breakfast for the week or need something quick for brunch guests, they never disappoint. The combination of creamy peanut butter and chocolate chips is basically foolproof happiness.

So grab your ingredients, preheat that oven, and get baking! Your kitchen’s about to smell amazing, and you’re about to have the best muffins on the block.
