It can’t always be cookies and buttercream, right? Maybe in a fairytale land far, far away where high cholesterol and weight gain don’t exist, but this isn’t a fairytale. Don’t get me wrong, I love me some cookies, but even I have limitations. Well, that is, my hips have limitations. If they’d let me, I’d probably snack on cookies all day; however, that’s not the case.

Sometimes I want to snack on something without feeling guilty about it later, so I’ve been experimenting with guilt-free quick breads in the kitchen lately. Breads full of whole grains, yogurt, fruit, and healthy proteins. Breads that will fill me up without leaving me full of eater’s remorse later. I love baking quick breads for the very fact that they involve little to no planning. They don’t require kneading, rising, or waiting, and can usually be whipped up in one bowl.

An challenged us to make a muffin using bananas this week, and I instantly knew that I wanted to make a muffin that combined chocolate, banana, and peanut butter. The epitome of all flavor combos. Last week I came across this recipe for Skinny Chocolate Peanut Butter Swirl Cupcakes by Sally’s Baking Addiction. I instantly fell in love with them and knew I had to make them for #MuffinMonday this week.

I made a few minor changes to make the recipe more muffin-like. I added some dark chocolate cocoa powder, white whole wheat flour, and brown sugar. They’re healthy and delicious all at the same time.
