Homemade Vanilla Extract:    • Vanilla Extract is Super Simple to Ma...   Ingredients 1 cup (227 g) unsalted butter softened 1 cup (235 g) creamy peanut butter I don't recommend using natural peanut butter 1 cup (200 g) light or dark brown sugar tightly packed 1 cup (200 g) granulated sugar 1 large egg + 1 large egg yolk 1 ½ teaspoons vanilla extract 2¾ cups (345 g) all-purpose flour ½ cup (65 g) graham cracker crumbs 1 teaspoon baking powder 1 teaspoon cornstarch ½ teaspoon salt 2 Tablespoons milk 7 1.55 oz milk chocolate Hershey bars chopped into pieces* or 2 cups milk chocolate chips (340g) 1 ½ cups (72 g) mini marshmallows Disclaimer: As an Amazon Associate I earn from qualifying purchases from the links below. 1 13×9 baking pan (Affiliate Link): https://amzn.to/2Sq9AOv Mixing bowls (Affiliate Link): https://amzn.to/2C47vQx Instructions 00:00 Introduction 00:18 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. 00:35 Combine butter, peanut butter, and sugar in a large bowl and use an electric mixer to beat until light, creamy and well-combined. 02:15 Add egg/egg yolk and vanilla extract, and stir well. 03:47 In a separate bowl, whisk together flour, graham cracker crumbs, baking powder, cornstarch, and salt. 04:30 Gradually, on low speed, add flour mixture to peanut butter mixture, pausing occasionally to scrape down sides of bowl. 05:20 Add milk and stir until combined. 06:03 Fold in chopped Hershey bars and mini marshmallows — the batter will be thick (I broke a spatula stirring it so proceed with caution!). 07:33 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). 09:33 Allow to cool completely before cutting and serving. Notes *I usually stir all but one of the Hershey bars into the batter and reserve one to press on top of the cookie dough once I’ve spread it into the pan — I think it makes the bars look prettier but you can just throw them in the batter if you prefer!
