Besides being super moist, (by using banana and peanut butter) I’ve added in a secret ingredient to get some protein in, by adding in some Quaker Banana Nut Protein Oatmeal. So besides skinny, you get a little more protein, and heart-healthy along with extreme yumminess too! Yay!  

However, if you don’t have access to the Banana Nut Protein Oatmeal, you can easily replace with any healthy quick oats.

I love this Quaker Banana Nut Protein Oatmeal for breakfast, and now I have it in these muffins and these 3 Ingredient Peanut Butter Banana Nut Oatmeal {No Bake} Protein Squares as well. Think I should tell Quaker?  Maybe I will… 🙂  

Oatmeal IS one of my favorite things to eat for breakfast, and I’ve been known to eat it for a snack and dinner too.  I absolutely love baking with it.

Oatmeal is definitely a staple in our home.  Now mind you, if you don’t have the Quaker Protein Oatmeal, you can use any kind of oatmeal, you just need about a half cup.

If you like skinny & healthy mini muffins, you could also try my Skinny Peanut Butter Banana and Chocolate Muffins {GF} and my Healthy Mini Pumpkin Oat Chocolate Chip Muffins. So, don’t fret, and make these Skinny Apple Peanut Butter Mini Muffins ASAP!  No pun intended, but my muffin-top was very, very happy! 🙂

If you don't have oat flour, you can process your own oat flour, by taking oats and pulsing them in a blender/food processor until they are a flour like consistency. Be sure to measure the oat flour after pulsing or the amounts will be off.

  1. Hi Deb! You can reduce it to 1/4 cup or leave as is. It’s such a small amount. Normally Oat Flour equals 1 & 1/3 cups ratio to 1 cup of all purpose flour. Hope that helps! Happy Baking!

  2. These sound like just what I’ve been looking for, I have a whole bag of Granny Smith apples just waiting to be used, thanks!
