Equipment

  • 1 Medium mixing bowl used for combining graham cracker crumbs, sugar, and butter
  • 1 Large heatproof bowl or small saucepan for melting the butter used in the brownie batter
  • 1 Whisk helps blend the batter until smooth and glossy
  • 1 Silicone spatula ideal for folding in chocolate chips and spreading thick batter
  • 1 9-inch pie dish standard depth and left ungreased for easy crust release
  • 1 Wire cooling rack allows airflow underneath the pie for even cooling
  • 1 Microwave or stovetop either method works for melting butter safely
  • 1 Oven with broiler option used to bake the pie and toast marshmallows if deeper color is desired

Ingredients

  • 225 g graham cracker crumbs finely crushed for even packing
  • 63 g granulated sugar used to lightly sweeten the crust
  • 106 g unsalted butter melted slightly cooled after melting
  • 141 g unsalted butter cut into pieces for easy melting
  • 38 ml vegetable oil or melted coconut oil adds moisture to the brownie
  • 250 g granulated sugar fully dissolved for a smooth batter
  • 3 large eggs brought to room temperature
  • 1 large egg yolk adds richness and chew
  • 2 ½ teaspoons vanilla extract pure extract preferred
  • 78 g unsweetened cocoa powder natural or Dutch-process both work
  • 78 g all-purpose flour spooned and leveled for accuracy
  • teaspoon salt balances sweetness
  • 225 g semi-sweet chocolate chips evenly distributed throughout batter
  • 30 large marshmallows pressed gently so they adhere

Instructions

  • Set the oven to 350°F (177°C) so it is fully heated before baking.
  • Combine the graham cracker crumbs and sugar in a bowl, then stir in the melted butter until the mixture looks sandy and cohesive.
  • Transfer the crumb mixture to an ungreased 9-inch pie dish and gently press it across the bottom and up the sides using light pressure until compact but not hard.
  • Melt the butter in a heatproof bowl until just liquefied, then whisk in the oil and sugar and let the mixture cool briefly for a few minutes.
  • Whisk in the eggs, egg yolk, and vanilla until smooth and fully blended.
  • Add the cocoa powder, flour, and salt, whisking until a thick batter forms with no dry pockets remaining.
  • Fold in the chocolate chips, then immediately spread the batter evenly into the prepared crust.
  • Bake the pie for 33 minutes until the edges are set but the center remains slightly soft.
  • Carefully remove the pie and arrange the marshmallows over the surface, pressing them lightly into the batter so they stay in place.
  • Return the pie to the oven and bake for an additional 3 minutes, or briefly broil until the marshmallows are toasted to your liking.
  • Remove from the oven and allow the pie to cool on a rack for at least 45 minutes, preferably longer for neat slices.

Notes

This pie captures everything cozy about classic s’mores with a bakery-style finish. Letting it cool fully rewards you with clean slices and deep chocolate flavor. Perfect for gatherings when you want comfort and nostalgia in every bite.
