Recipe Ingredients

1 cup unsalted butter (melted)
1 cup white sugar
1 cup firmly packed light brown sugar
2 large eggs (well beaten)
2 cups self-rising flour
2 teaspoons vanilla extract
1 (15.35-ounce) package Halloween Oreos, coarsely chopped or broken into pieces
Halloween sprinkles (optional)

Instructions

Preheat and Prepare Pan: Preheat your oven to 300°F (150°C). Lightly spray a 13×9-inch light-colored metal baking pan with nonstick cooking spray to prevent sticking and ensure easy removal of the bars.
Combine Butter and Sugars: In a large mixing bowl, stir together the melted unsalted butter, white sugar, and firmly packed light brown sugar until well combined, creating a smooth and rich base for the batter.
Add Eggs and Flour: Beat the eggs in a separate bowl and add them to the sugar mixture, stirring well. Then gradually add the self-rising flour, stirring continuously until the batter is smooth and free of lumps. Stir in the vanilla extract for added flavor.
Fold in Oreos: Gently fold about two-thirds of the coarsely chopped Halloween Oreos into the batter to distribute the cookie pieces evenly throughout the mixture.
Assemble and Add Toppings: Spread the batter evenly into the prepared baking dish. Sprinkle the remaining Oreo pieces on top, and optionally add Halloween sprinkles to give your bars a festive, colorful finish.
Bake: Place the pan in the preheated oven and bake for approximately 40 to 50 minutes. To avoid overbaking, check the edges for firmness while ensuring the center remains chewy. The bars should be set but still soft.
Cool and Slice: Remove from oven and allow the Oreo Chewies to cool completely in the pan. Once cooled, slice into squares. Store the bars in an airtight container to maintain freshness.

Notes

The lower baking temperature of 300°F helps achieve a fudgy, chewy texture rather than a crispy cookie.
Using a light-colored metal baking pan prevents overbrowning on the edges during the longer baking time.
Self-rising flour already contains leavening agents, so no baking powder or baking soda is necessary.
Be cautious not to overbake; the bars are best when just set and still moist inside.
Add Halloween sprinkles for a fun decorative touch, or substitute with any sprinkles you prefer.
Store the baked bars at room temperature in an airtight container for up to 5 days or freeze for longer storage.
