I made these for my friend's hen weekend a few days ago. The recipe originally came from this blog, which is a fantastic place that's responsible for my waist gradually getting wider.
I've British-ised the recipe for my own purposes. S'mores are an American campfire snack, traditionally made of Graham crackers with chocolate and marshmallows sandwiched in between them, toasted over a campfire. The closest British relative to Graham crackers is Digestives, so that's what I used.
S’more cookie bars
- 110g butter, room temperature
- 50g brown sugar
- 115g sugar
- 1 large egg
- 1 tsp vanilla extract
- 160g all purpose flour
- 6 digestives, crushed (stick them in a plastic bag, knot it, bash with rolling pin)
- 1 flat tsp baking powder
- 2 king-sized milk chocolate bars
- ½ jar marshmallow creme/fluff
Note: The recipe says do not use marshmallows, only marshmallow fluff. You can get this fluff in big supermarkets like Asda, in the world foods aisle. It’s basically marshmallow in a jar. It’s not especially cheap for what it is. This is what I used BUT I want to try these again with cut up marshmallows as I think it would still work. I’ve used marshmallows in recipes before and they do melt. Re: the quantity – use enough to cover your pan, basically.
1 – Preheat oven to 350°F. Grease an 8-inch square baking pan.
2 – In a large bowl, cream together butter and sugar until light. Beat in egg and vanilla. In a small bowl, whisk together flour, graham cracker crumbs, baking powder and salt. Add to butter mixture and mix at a low speed until combined.
3 – Divide dough in half and press half of dough into an even layer on the bottom of the prepared pan. Place chocolate bars over dough. 2 king-sized Hershey’s bars should fit perfectly side by side, but break the chocolate (if necessary) to get it to fit in a single layer. Spread chocolate with marshmallow creme or fluff. Place remaining dough in a single layer on top of the fluff (most easily achieved by flattening the dough into small shingles and laying them together).
4 – Bake for 30 to 35 minutes, until lightly browned. They probably won’t look cooked, but that’s a good thing. Cool completely before cutting into bars.
Makes 16 cookie bars.
(Note, if you don’t have time to cool completely, lift out and stick in muffin cases to avoid messiness. They won't entirely fall apart, but they won't be quite as neat as they should be, due to gooey marshmallow and melted chocolateness. Technically, these should be square and brownie-like, though.)
I had some leftover chocolate so I drizzled it over the top.
Sadly I didn't get a chance to take a picture after cutting them up.
Guys, these were GOOD. The cookie dough was just cooked enough so it was still soft and tasty, the marshmallow was gooey and... god, they were amazing. So popular, all the very British hens were intrigued by the concept of s'mores (I'm hardly an expert, but I read a lot of Babysitter Club books when I was a kid) and I will definitely be making them again.
