I’m obsessed with all things banana. So naturally, I’m a bit of a sucker when it comes to banana bread or muffins. These jumbo banana chocolate chip muffins are my latest and greatest creation.

They’re light, moist, and bursting with chocolate chunks and chips just like my Banana Oatmeal Chocolate Chip Muffins.

Why We Love This Recipe

  • They’re jumbo! No need to eat half a batch, one will do trick!
  • Bananas and chocolate chips are one of the best combinations in baking. The flavors mesh so well together like in my Banana Chocolate Chip Cookies.

Recipe Ingredients

Bananas – You want these to be very ripe! They’re softer in texture and sweeter in taste!

How to Make Jumbo Banana Chocolate Chip Muffins

Step 1: Preheat your oven to 425 degrees. Spray or line 1 jumbo muffin tin, set aside.

Step 2: In a large mixing bowl mix together the sugar, vegetable oil, melted butter, eggs and vanilla. Add the mashed banana and stir in just until combined.

Step 3: In a medium bowl whisk together the flours, baking powder and salt. Alternate adding the dry ingredients and the buttermilk to the wet ingredients. Fold in any chocolate chips or chunks. Do not overmix! The batter should look slightly lumpy- that’s what you want.

Step 4: Scoop or pour the batter into the prepared jumbo muffin pan. Fill each well 1/4″ from the top (they should be VERY full). Place in the oven and bake at 425 degrees for 5 minutes, then turn the heat down to 375 degrees and continue baking for an additional 25 minutes. The tops should be lightly golden brown in color.

Yes! To make regular sized muffins reduce the baking time to 18-22 min. Muffins are done when an inserted toothpick comes out clean.

I used semi-sweet chocolate chips and mine were actually mini chocolate chips as well. And the chunks were semi sweet as well. However if you prefer milk chocolate or dark chocolate you can use these instead!
