Ingredients
Method
- Preheat oven to 350F (175C) and line a 13×9 metal pan with parchment paper or grease and flour the sides and bottom of the pan.
- Combine butter, peanut butter, and sugar in a large bowl and use an electric mixer to beat until light, creamy and well-combined.
- Add egg/egg yolk and vanilla extract, and stir well.
- In a separate bowl, whisk together flour, graham cracker crumbs, baking powder, cornstarch, and salt.
- Gradually, on low speed, add flour mixture to peanut butter mixture, pausing occasionally to scrape down sides of bowl.
- Add milk and stir until combined.
- Fold in chopped Hershey bars and mini marshmallows — the batter will be thick (I broke a spatula stirring it so proceed with caution!).
- Spread batter into prepared ban and bake on 350F (175C) for 25-28 minutes (toothpick inserted in center should come back mostly clean with only a few crumbs)
- Allow to cool completely before cutting and serving.
