Never throw away your overripe bananas anymore! Here’s a delicious and nutritious way to use them – banana brownies with peanut butter swirl.

I always buy the most unripe bananas possible. I hate eating soft squishy fruit with dark spots. So when I buy a whole bunch of unripe bananas, I can enjoy them as they are or with my morning oatmeal for about 4-5 days. After that they fall straight into “for baking” category.

I like those moments, when you wake up in the morning, go to the kitchen with zero ideas for breakfast and see a bunch of unappealing dark ripe bananas in your fruit basket. And here it is, you don’t need to worry about breakfast anymore! Banana bread? Yes, please! Peanut butter banana smoothie? Why not! Chocolate chip banana pancakes? Absolutely! Banana brownies with peanut butter swirl? Oooh, yes!

This recipe is full of nutritious ingredients, and it’s vegan too!
