Peanut Butter Apple Crumb Muffins


Happy National Apple Day!

I hope you all are going to celebrate by eating copious amounts of apples. Or maybe just watch football all day. Or do something productive, like fold hand towels. Whatever you decide to do, just make sure you’ve got apples on the mind. After all, it is a national holiday.

That’d be like not thinking about Christmas on Christmas. Blasphemy.

Anyway, after discovering this website (which gives you the lowdown on everything from National Lobster Bisque Day to National Indian Pudding Day [whatever that may be]), my family and I got a little bit excited discovering our birthday holidays.

My sister was quite disappointed to have been born on National Bittersweet Chocolate Day and was jealous I was born on National Peanut Butter Day. I shared a giggle that my grandma was born on National Hot Buttered Rum Day. Or that our dog, Oreo, was born on Wienerschnitzel Day (another reason to eat five pretzel dogs).

Anyway, when CrunckPak sent me a bunch of (awesome!!) apples, my first thoughts were “snacks!!” and practically had to fight off my family from stealing all my apples. But after day 2, I decided I wanted to bake something with all the gorgeous apples! Muffins came to mind, and when I saw Jocelyn’s recipe for Biscoff Apple Muffins, I knew I wanted to do a peanut butter version.

Like an homage to my birthday or something.

After all, it is a national holiday 🙂

Peanut Butter Apple Crumb Muffins *adapted from Jocelyn’s Biscoff Apple Muffins recipe 

For Muffins:

1/3 cup quick oats
1 & 2/3 cup flour
1 tsp baking powder
1/2 tsp baking soda
1 cup sugar
1 tsp cinnamon
1/4 tsp nutmeg
1/3 cup oil
2 eggs
1/4 cup buttermilk (I used low-fat)
1 tsp vanilla extract
1/4 cup smooth peanut butter
1 cup chopped and peeled apples (I used gala, but Granny Smith works too)

For Topping:

3/4 cup oats
1/2 cup flour
1/4 cup sugar
1/4 cup brown sugar
1 tsp cinnamon
1/3 cup cold butter

1. Preheat oven to 350 degrees F. Line a muffin tin with about 15-16 muffin cups. Set aside.
2. In a large bowl, combine all the dry ingredients. Add all the wet ingredients except for the apples, and beat to combine. Stir in the apples by hand.
3. Portion the muffin batter evenly among the muffin cups, about 2/3 full. Meanwhile, in a separate medium bowl, combine the topping ingredients and cut the butter into the topping using forks or a pastry blender until it forms coarse crumbs. Top the muffin batter with a generous heap of the crumb topping.
4. Bake for approx. 20-25 minutes, checking at the 20 minute mark, until golden and a toothpick inserted near the center comes out clean. Cool completely. Store airtight.

Apples and fall go hand in hand, and I loved these apple muffins. The peanut butter flavor isn’t too overwhelming but lends a nice nutty kick to these moist muffins. And anything topped with a brown sugary streusel topping is perfect in my book. Plus, using CrunchPak apples were so simple–they’re precut, so it made slicing off the peels and chopping them a breeze. Plus, the ones I didn’t bake with I snacked on–win-win, methinks.

Happy Apple Day!!

  1. Holy apple that looks AMAZEBALLS! I can never keep apples in this house for long…every day is apple day here.

  2. That holiday list has changed my life. I didn’t know I was born on National BBQed sparerib day!! I love the cinnamon crumbs on those muffins! Now THAT is a muffin top I LIKE! Happy Apple Day!

  3. National apple day? How could I miss such a thing! PB & apples are such a yummy combo. I smear PB on them every time I have one. SO good on honeycrisp apples! I was born on grape popsicle day. Random.

  4. Yumoriffic! Love apples. In fact, I can’t believe I haven’t done anything apple-y yet! I bet they taste amazing with the spice combos, PB and the apples. That crumbly topping looks amazing too.

    I had no idea it was national apple day, damn it. I need to know these holidays in advance, I need to create a baker’s calendar with all these events, etc. LOL.

  5. YUMMY! These look incredible! PB and apple sound lke a fantastic combination…can’t believe I missed national apple day : )

  6. Oh girl, these looks so so good! Love any excuse to eat my face off with apples.

  7. PB and Apple?! Yes, please! These look so good! Love the oat-y crumb topping too! 🙂

  8. Okay, these sound totally amazing. Do you know I do actually eat an apple They are my fave mid-morning snack, but I could easily see myself switching over to eat one (or more) of these muffins instead!

  9. Love love love! My birthday is International Banana Day and Pecan cookie day. Hmmmm….

  10. I love your pictures!!! So beautiful! I would also love to grab a muffin right out of my computer screen! They look so delish!

  11. Do you remember how many days these muffins will stay fresh?

    • Hi Elizabeth! These muffins should stay fresh when stored airtight, at room temperature, one to two days. I like them slightly nuked in the microwave–it softens them and they taste yummy warm.
