Directions for: Mudslide Critter Bars


Sandwich Cookie Crust

Nonstick cooking spray

26 chocolate sandwich cookies, such as Oreos

4 Tbsp unsalted butter, melted

⅛ tsp kosher salt

Brownie Filling

8 oz bittersweet chocolate, chopped

1 stick unsalted butter, cut into 8 pieces

¾ cup all-purpose flour

¾ cup granulated sugar

¼ cup packed light brown sugar

3 Tbsp unsweetened cocoa powder

1 tsp salt

1 tsp vanilla extract

3 large eggs

½ cup white chocolate chips

1 cup gummy worms, for topping


Sandwich Cookie Crust

1. Place a rack in the center of the oven and preheat to 350ºF. Grease the bottom and sides of an 8-by-8-inch baking pan with the cooking spray.

2. Place the cookies in a food processor and grind into fine crumbs. Reserve 1/2 cup of the crumbs for a later use.

3. Place the remaining crumbs in a bowl and stir in the melted butter and salt. Press the mixture into the bottom of the prepared pan evenly and transfer to the refrigerator to chill while you prepare the brownies.

Brownie Filling

1. Place the chocolate and butter in a heatproof bowl set over a saucepan filled with 1 inch of water to make a double boiler. Set the double boiler over medium heat and stir to melt. Set aside to cool slightly.

2. In a medium bowl, mix together the melted chocolate mixture, the flour, granulated sugar, brown sugar, cocoa powder, salt, vanilla and eggs. Fold in the white chocolate chips, and then pour the batter into the chilled crust. Bake until set, 28 to 30 minutes.

3. Transfer to a wire rack to cool completely.

4. Sprinkle the reserved cookie crumbs over the finished brownie dish. Tuck the gummy worms on and into the cookie crumb "dirt." Cut the brownies into squares to serve.
