Amazingly Tasty S’mores Bars

1 stick (1/2 cup) unsalted butter, softened, plus more for greasing

1/3 cup brown sugar

1/3 cup granulated sugar

1 teaspoon vanilla

2 large eggs

1.5 cups all-purpose flour

1 cup graham cracker crumbs

1 teaspoon baking powder

1/2 teaspoon salt

1.5 cups semisweet chocolate morsels

One 200g. container marshmallow creme

Preheat the oven to 180ºC . Grease an 20 by 20 cm. baking pan and line with aluminum foil.

Stir together the butter and sugars in a large mixing bowl until light and fluffy. Mix in the vanilla and eggs until fully merged.

Mix together the flour, graham cracker crumbs, baking powder and salt in a separate mixing bowl. Slowly add the dry ingredients to the wet ingredients until combined. Divide the dough in half.

Press half of the dough into the bottom of the prepared pan. Sprinkle the chocolate evenly over the dough. Top the chocolate with the marshmallow creme.

Spread the marshmallow creme in an even layer, using a rubber spatula that has been sprayed with nonstick spray.

Roll out the remaining dough to an 20 by 20 cm. square on wax or parchment paper, using a rolling pin. Working carefully, place the dough on top of the marshmallow layer

Bake until the crust is golden brown, 30 minutes. Completely cool before cutting into bars.
