Start by laying your pastry puff out flat on a piece of parchment paper on top of a cookie sheet. Place your bowl in the center and cut around it with a knife.

Remove the excess dough. You can use a toothpick to trace out the shape of a tree in the center.

Spread out your Nutella in the center, in the shape of a tree, as shown.

Spoon some marshmallow fluff on top of your Nutella.

Start by cutting a triangle with a sharp knife out of the top of the pastry puff aligned with the top of your tree.

Next, cut diagonal lines from the top of your tree to the bottom corners on both sides. Make sure they are evenly spaced.

Cut two lines straight down at the base of your tree for the trunk.

Cut two additional triangles out at each corner of the bottom of the tree, as shown.

Begin folding on each side, crisscross, like a shoelace, starting at the top.

Before making your last two folds, fold in the bottom and your trunk piece.

Fold in the remaining two slices on each side.

Use the remaining dough to cut out a star and place it at the top.

Coat everything in melted butter using your basting brush.

Sprinkle with graham cracker crumbs.

Bake at 375 degrees for 10 to 15 minutes, until golden brown.

Add sprinkles or powdered sugar (optional).

Serve warm.
