Fluffy Apple Muffins are filled with apple chunks and tons of cinnamon flavor with brown sugar crumble topping. This is the perfect muffin recipe for fall!

I fell in love with this muffin recipe because of the crumb topping. If the crumb recipe isn’t the best part of any recipe, then I don’t know what is. I turned my favorite all-purpose muffin recipe into an apple muffin because we are apple lovers – especially in the fall.
My secret to moist muffins is using sour cream instead of milk – the acid and moisture in the sour cream keeps these muffins moist for days.

Apple Muffin Ingredients
- Apples: Peeled, cored, and diced very small. Use your favorite kind of apple!
- Butter: You’ll need melted butter for the crumble topping. I love using unsalted butter!
- Vegetable oil: I find oil best for making a tender muffin – plus it makes them easy to mix.
- White vinegar: Interacts with the baking soda and sour cream to help the muffins rise nice and fluffy with the perfect muffin tops.

Dorothy’s Testing Notes
- Fill muffin cups 2/3 full of batter (about 1/4 cup per muffin cups) for the best results. I love using a cookie scoop for this!
- If your batter is slightly lumpy after adding the sour cream that’s okay, just make sure it’s fully mixed.
- Store in an airtight container for up to 3 days or freeze for up to one month.

How to make Apple Muffins

1. We cook the apples in the microwave for a few minutes so they soften enough to add to the muffin batter. They should be soft and slightly opaque.

2. The crumble should be pea sized chunks.

3. Gently fold the apples into the thick muffin batter at the end.

4. Divide among 12 cupcake liners and top with crumble.
FAQs
Granny Smith and Gala are my favorites, but you can use whatever you would like!







These look so wonderful, but can I substitute unsweetened applesauce for the oil? Thanks for all your great recipes!
Yes you should be able too! I’ve done that in other recipes, but not this one.
Do you recommend any certain type of Apple? Do you peel them?
I used Gala but you should use your favorite apple. I did peel them, yes.
These look delicious- -!and I vote YES on wine with breakfast! ?
Yum, are these the ones that we tried? Very good and the crumble just takes them over the top!
Yep, but yours were berry. 🙂
I suck at muffins. It is the #1 fail I have. I always think…this will be the time I am going to perfect my base dough and have it for life. And then they either spread like crazy all over the muffin pan or sink like mad upon cooling. Major props to you for recreating the best muffins of your life! Oh and crumb topping…when I try, I swear half the time it compresses the muffin and it won’t rise. Muffins and me just don’t get along so I will try these, verbatim. Thank you for your hard work!
This base recipe is the best one I’ve found! That vinegar and baking soda combo is the best.
