Preheat the oven to 350°F. Lightly spray a 9-inch pie dish with non-stick baker's spray and set aside.
02 -
In a large mixing bowl, add the unsalted butter and granulated sugar. Beat for 1-2 minutes or until light and fluffy using a hand mixer on medium-high speed.
03 -
Add the egg and vanilla extract to the butter mixture and beat again until well combined and smooth.
04 -
To the bowl of wet ingredients, add the all-purpose flour, finely ground graham cracker crumbs, baking powder, and salt. Mix just until combined and the crust mixture forms a ball. Divide the dough in half.
05 -
Press half the graham cracker dough into the bottom and up the sides of the prepared pie dish, being sure to press the dough out evenly in the dish.
06 -
Spread the marshmallow creme into a single layer in the bottom of the crust.
07 -
Set aside ⅓ cup of the roughly chopped Hershey's milk chocolate candy bars. Use the remaining chopped chocolate bars to evenly spread over the marshmallow creme in the pie dish.
08 -
Sprinkle ⅔ cup of the mini marshmallows over the chopped chocolate bars.
09 -
Place the other half of the graham cracker crust dough onto a large piece of parchment paper on the counter, and press into a 9-inch round disc.
10 -
Place the disc of dough onto the top of the s'mores pie. Using your fingertips, gently press and seal the edges together.
11 -
Bake in the preheated oven for 10 minutes, then remove from the oven.
12 -
Top the warm crust with the remaining ⅓ cup mini marshmallows and ⅓ cup chopped Hershey's milk chocolate candy bar.
13 -
Return the s'mores pie to the oven and continue to bake for another 8-10 minutes or until the crust is lightly golden around the edges, the marshmallows have lightly browned, and chocolate is melty.
14 -
Remove the s'mores pie from the oven and allow it to cool at room temperature for 45 minutes to 1 hour or until cool enough to slice and serve. If too warm, it might still be quite gooey and not hold its shape as well when sliced and served.
