Treat Yourself – Fluffernutter Bars

Chocolate, check! Peanut butter, check! Marshmallow fluff, check! This is such an easy recipe but I could eat these bars all day!


Fluffernutters are an American thing, but I see absolutely no reason why the UK can’t enjoy peanut butter and marshmallow together and its my dream combination of sweet food!

You’ll need: 250g biscuits – I used chocolate chip cookies, 1/3 cup butter, 1 1/2 cups peanut butter, 2 tbsp icing sugar, 2 tsp vanilla extract, 1 jar Marshmallow Fluff and 200g milk or dark chocolate. You’ll also need an 8 inch square tin.


1. Start by lining your tin carefully with greaseproof paper. Crush up your biscuit of choice into fine crumbs, then melt the butter and combine with the crumbs, then press into the base of the tin. Pop this in the fridge to harden while you work on the peanut butter.


2. Don’t worry about using a fresh bowl here, any remaining biscuit crumbs won’t hurt! Scoop out your peanut butter; I used smooth but you could absolutely use crunchy if you fancied it. Add the icing sugar and beat together. If your PB mix is really thick here, add the vanilla to make it more pliable. Scoop this nutty paste onto the biscuit base and spread evenly.


3. I apologise for this next step; working with Marshmallow Fluff is like working with tar, good luck. Empty the contents of your jar onto the peanut butter layer and spread it out as best you can. I recommend scattering blobs of the stuff all over the place, then letting it settle in its own time – you’ll find the whole thing a lot less stressful than fighting it with a spatula.


4. Once your fluff has settled and you’re happy with the coverage, melt your chocolate, and pour evenly over the marshmallow. I say pour evenly because if you dump it all in the middle, the gooey fluff is gonna melt away underneath, so work quickly to pour it out and spread it to cover the whole of the tray.

5. An hour or so in the fridge, and these babies are ready for chopping up. You may find the chocolate shatters as you slice, but who needs uniform edges on their bars, right? Store your bars in the fridge, otherwise your marshmallow is going to try and escape.
