Ingredients

  • 170 gram Unsalted butter (6oz) just melted and cooled for 5 minutes
  • 180 gram Light brown sugar (6.3oz)
  • 120 gram White sugar (4.2oz)
  • 1 Egg room temperature
  • 1 Egg yolk room temperature
  • 1 tbsp Vanilla extract
  • 260 gram Plain flour (9oz)
  • 1 tsp Bi carb soda
  • ½ tsp Baking Powder
  • ¼ tsp Salt
  • 4 Honey Graham Crackers, roughly crushed approx 60g. SEE NOTES FOR SUBSTITUTION
  • 2 Honey Graham Crackers, roughly crushed approx 30g for rolling
  • 200 g Semi sweet chocolate chips (1 cup or 7oz)
  • 1 pkt marshmallow fluff or mini marshamallows I use approx 8 per cookie

Instructions

  • Heat oven to 180°C/350°F/160°FF
  • Heat butter in microwave until it's just melted. Set aside while you prep the other ingredients.
  • Line 3 baking trays with baking paper. See notes
  • Sift the flour, bi carb soda, baking powder and salt together. Set aside
  • In the bowl of a stand mixer, combine the cooled melted butter and sugars until well blended
  • Add the egg, egg yolk and vanilla and beat until light and creamy, then continue to beat on medium-high for another 5 minutes.
  • Stop the mixer, add the flour mixture and beat until almost combined
  • Remove bowl from stand, add the 4 crushed Graham crackers and choc chips then combine with a spatula. DO NOT OVERMIX
  • Using a large ice-cream scoop, scoop out balls of cookie dough
  • Make an indent in the top of each ball. Fill indent with 6-8 mini marshmallows, then roll back into a ball
  • Toss each cookie ball into the extra crushed crackers, then place onto prepared baking sheet, leaving plenty of space to spread. I put 6 on each large cookie tray
  • Bake cookies for 12 minutes, until lightly golden. Remove from oven and transfer the cookies (still on the baking paper) to a bench. After 5 minutes, transfer to a cake rack to cool.
  • Cookies will last well for a few days, in an airtight container

Notes

  • Graham Crackers can be a tough find in Australia, so substitute them with Digestive biscuits if needed.
  • I like to place 6 cookie dough balls on each large baking tray, giving them plenty of space to spread.
  • I bake one tray at a time in a conventional oven (not fan-forced)
  • Cookie dough balls can be frozen -simply place a tray of dough balls into the freezer for 10 minutes, then pop them into snap lock bags -make sure you label them with cooking instructions!
