Toasted Marshmallow Chocolate Banana Oat Bars

Toasted Marshmallow Chocolate Banana Oat Bars – the perfect recipe for overripe bananas sitting in your fruit bowl and a treat that the whole family will love.

S’mores Oat Bars

Last night I was making a treat for the kids after dinner – A popular sweet treat this side of the Atlantic called S’mores which consists of toasted marshmallows sandwiched between two graham crackers with chocolate so that the chocolate goes all melty from the hot toasted marshmallows. It’s absolutely heavenly if a little sweet.

Fast forward to today and the two ripe bananas sitting in my fruit bowl where in desperate need of being used in a recipe. Normally it would be this yummy Banana and Chocolate Chip loaf, but I fancied a little something different, and that’s when last nights treat popped into my head.

Not yet using my healthy extra B choice, I had the genius idea to make some chocolate banana oat bars with yummy toasted marshmallows on top. AKA S’mores Oat Bars – yum!!!

Yummy Recipe for Overripe Bananas

I don’t know about you, but I always end up with overripe bananas, mainly because as a family we like to eat them when the skin is still a little green, so once they get past that, they are ignored in the fruit bowl and then we either freeze them for smoothies for the kids or turn it into a delicious baked good like these Toasted Marshmallow Chocolate Banana Oat Bars.

More Recipes for Overripe Bananas

Got more than a couple of overripe bananas in your fruit bowl, check out some of these other recipes:

  • Cookies and Cream Oat Bars
  • Mini Banana Raisin Loaf
  • Banana Chocolate Chip Muffins
  • Baked Banana Doughnuts
  • Healthy Banana Granola
  • Banana Baked Oats

How to make  Toasted Marshmallow Chocolate Banana Oat Bars

The first part to make is of course the base, which is like many of my baked oat recipes, using up those overripe bananas for sweetness and then adding a layer of chocolate chips in the middle.

I use a square brownie pan, mainly because you can then slice into perfect squares and enjoy 4 as a healthy extra B choice plus 5 syns. 

Parchment paper comes in handy as always for lining the tin, it will make the oat bars easier to remove and prevent any messy tin to clean up afterwards.

Once the baked oats part is cooked, the last and final part is that amazing topping of Toasted Marshmallows. 

I recommend letting the base cool slightly before adding the marshmallows, just to prevent them from melting before you get a chance to toast them.

Then it’s just a case of placing the oat base with marshmallow topping under the grill or broil and toasting for a few minutes.

NOTE: Don’t leave them unattended as they can burn really quickly, you want to make sure you watch them and take out once perfectly done.

A great snack for the kids (or neighbours)

Then let them cool again slightly before slicing – you can either slice into 4 big bars, or 16 mini bars. I like to do 16, as it means I can split them up and enjoy through out the day – if the kids (or neighbours )do not get to them first.

My neighbour popped over just as I was photographing these and waited to try one out, remarking that they were delicious and I must get the recipe up on Slimming Eats quickly so she can make some too. 

I stored these in a large lidded tub once cooled down, but if you have kids like me, then they won’t last long.

Can these be frozen?

Freezing I haven’t tested yet, I think if you want to freeze these then do so without the marshmallow topping and add a few marshmallow and broil/grill as you want them.

    Was thinking of doing this in muffin form instead of like a tray bake, would the cooking times be less for this?

    yes muffins should work, I would start checking from around the 20-25 minute mark.
