    1. These cookies look gorgeous! My dad used to make peanut butter cookies when we were kids, but I’ve never had them with banana – that sounds incredible! I bet it helps to keep those cookies nice and moist too (sorry dad, you’re cookies, while delicious, were sometimes a little dry). The drizzle of chocolate on top is like the piece de resistance!

    2. I have a firm belief that peanut butter goes with just about everything! I’ve even tried it spread on a burger and loved it… These cookies sound like the perfect combination of flavors and I love how you used low-fat peanut butter and less sugar because of the sweetness of the bananas. Gorgeous pictures too, Mira!

    3. These cookies are adorable! Soft and chewy cookies are my favorite and I love the peanut butter, banana and chocolate combo! Sign me up for dozen – yum!

    4. I am so happy I cannot eat fruit or gluten or sugar or dairy because… If I could… I would gobble these up in NEGATIVE 5 seconds! NO JOKE!

    5. Hi5! I made peanut butter and banana chocolate cookies this week too! I am yet to post them though 😉 The only difference is that you have this talent of making everything look super gourmet and professional! Love x

    6. Love those cookies! I love banana bread and anything with peanut butter, but never thought to mix them together and bake some cookies! The recipe seems easy and perfect for a friend gathering. Saved!
