A loaf of s'mores banana bread by Rachel Dunston

S’mores Chocolate Banana Bread

You’ve probably tried chocolate chip banana bread. It’s delicious, right? This incredible recipe from Rachel Dunston takes it to the next level by adding rich dark cocoa powder, marshmallows, chocolate chunks and graham cracker pieces to the batter. She says it gives it the banana bread “a yummy chocolate sandwich cookie vibe”.

Gimme s’more…Chocolate Banana Bread

What’s the final touch to that puts this decadent dark chocolate banana bread over the top? After baking the bread, Rachel adds more chocolate chunks, marshmallows and graham cracker pieces onto the top of her finished loaf. If you’ve got a kitchen torch, now’s your chance to fire it up and get the topping all gooey and golden. If you don’t have a kitchen torch, simply broil the loaf in the oven for a few minutes.

A healthy twist

Rachel is known for her decadent treats, but as a mother of two, she doesn’t miss an opportunity to add a little extra fiber and fruit into her craveworthy confections. One of Rachel’s favorite tricks is to use prune purée in place of vegetable oil or eggs. She particularly loves this healthy swap in rich, chocolate recipes.

P.S. -If you haven’t heard, prunes and chocolate are a match made in heaven. Not convinced? This Chocolate Fudge Cake should do the trick.
