Step 1

Set the oven to 350F

Step 2

Lightly spray a 9x9 baking pan. Line with parchment paper if you want to lift your bars out for easy slicing.

Step 3

Grind the graham crackers in a food processor until finely ground. It helps to break them apart as you add them to the machine. Process until the mixture is very finely pulverized, with no lumps.

Step 4

Mix the cracker meal with the flour and salt and set aside.

Step 5

Cream the butter and sugar until light and fluffy. Add in the vanilla bean paste and blend well.

Step 6

Add in the flour/graham mixture and fold in until well combined.

Step 7

Press 2/3 of the dough into your baking pan. Using your fingers, spread the dough evenly across the pan so it covers the entire bottom.

Step 8

Spread the Nutella over the dough.

Step 9

Using a small spoon, dollop the marshmallow fluff evenly across the Nutella. You don't need to spread it out, but try to get small dollops evenly distributed across the entire surface.

Step 10

Crumble the remaining 1/3 of the dough over the top. Use your fingertips to break it apart into small pieces and scatter it evenly across the surface. Some of the marshmallow will peek through.

Step 11

Bake for about 35 minutes until lightly golden and puffed up a bit.

Step 12

Let cool before cutting if you want neat squares, but these are pretty amazing while they are still warm.
