Ingredients:
- 1 cup (227g) unsalted butter, melted
- 1 cup (200g) granulated sugar
- ½ cup (100g) packed light brown sugar
- 2 large eggs
- 1 teaspoon vanilla extract
- ¾ cup (90g) all-purpose flour, spooned and leveled
- ½ cup (45g) unsweetened cocoa powder
- ½ teaspoon baking powder
- ¼ teaspoon salt
- 1 ½ cups (180g) all-purpose flour
- ½ cup (115g) unsalted butter, softened
- ½ cup (100g) granulated sugar
- ¼ cup (50g) packed light brown sugar
- 2 tablespoons milk
- 1 teaspoon vanilla extract
- Pinch of salt
- 18 Oreo cookies, crushed
Instructions:
- Preheat oven to 350°F (175°C). Grease and line a 9x13 inch pan with parchment paper, leaving an overhang.
- In a large bowl, whisk together melted butter, granulated sugar, and brown sugar until well combined. Beat in eggs one at a time, then stir in vanilla extract.
- In a separate bowl, whisk together flour, cocoa powder, baking powder, and salt.
- Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Do not overmix.
- Pour batter into the prepared pan and spread evenly. Bake for 25-30 minutes, or until a toothpick inserted near the center comes out with fudgy crumbs attached. Let cool completely in the pan.
- Place the flour for the edible cookie dough in a microwave-safe bowl. Microwave on high in 30-second intervals, stirring between each interval, until the internal temperature reaches 165°F (74°C). Let cool completely.
- In a large bowl, cream together the softened butter, granulated sugar, and brown sugar until light and fluffy.
- Beat in milk and vanilla extract. Gradually add the heat-treated flour and salt, mixing until just combined.
- Gently fold in the crushed Oreo cookies.
- Spread the Oreo cookie dough evenly over the cooled fudgy base.
- Refrigerate for at least 15 minutes to allow the cookie dough to set slightly. Cut into bars and serve.
