Equipment

8" square baking tray

Ingredients

10 tablespoon unsalted butter melted
1 cup light brown sugar firmly packed
⅓ cup granulated sugar or caster sugar
2 large eggs at room temperature
1 teaspoon vanilla extract
1 cup all purpose flour or plain flour
2 teaspoon cornstarch
¼ teaspoon baking powder
½ teaspoon salt
½ teaspoon ground cinnamon
¾ cup graham cracker crumbs
6 oz dark chocolate chips
5 oz mini marshmallows

Instructions

Begin by preheating your oven to 350℉ (175C/155C Fan) and lining an 8" square baking pan with parchment paper.
In a mixing bowl, whisk together melted butter and your sugars until well combined (about 2 minutes).
Add the eggs and vanilla extract and again whisk to combine.
Sift the flour, baking powder, cornstarch, salt and cinnamon into the mixing bowl. Then, add the graham cracker crumbs. Use a spatula to stir the batter together. It should be fairly thick and may have some small lumps due to the graham cracker crumbs. Avoid overmixing, but ensure there aren't any pocked of unmixed flour or dry ingredients.
Add the chocolate chips to the batter and stir through.
Pour the mixture into the prepared baking pan and spread in an even layer.
Bake in the centre of the preheated oven for about 40 minutes, until a toothpick inserted about 2" from the corner of the pan comes out mostly clean.
Remove from the oven and top with mini marshmallows.
Change your oven to a broiler setting and cook under the broiler watching carefully until your marshmallows expand and toast to your taste. (see note)
Allow your blondies to cool for about an hour to allow them to firm up enough for easy slicing. For best results, cut with an oiled knife. This will help limit the marshmallows sticking to the blade.

Notes

Note on Toasting Marshmallows

This can be achieved with the broiler (in the UK referred to as grill). Set this to a medium setting and place your pan underneath, keeping an eye on the marshmallows. These will begin to puff up and go golden. They will burn quickly if unwatched, so do stay with them while you're toasting.
As an alternative, you can use a kitchen blow torch to toast these marshmallows. Again this should be done carefully as marshmallows catch fast! Toast to your heart's content.
The benefit of a kitchen torch is a bit more control of the areas being toasted, but it does require an extra piece of equipment, which not everyone will have available.
