Eggs These bind everything together while providing moisture; flaxseed meal can substitute for a vegan option.

How to Make Halloween Oreo Cookie Boo Brownies

1. Preheat your oven to 350 °F (175 °C) and line a 9×9-inch baking pan with parchment paper. This step ensures that your brownies come out easily and maintain their shape!
2. Melt the butter in a saucepan over low heat, then combine it with sugar in a bowl. Mix well until fully integrated, then add the eggs one at a time, stirring in the vanilla extract for a hint of warmth.
3. Incorporate the all-purpose flour gradually into the mixture. Mix until just combined, ensuring you don t overmix, which helps keep the brownies delightfully chewy.
4. Fold in the crushed Halloween Oreo cookies and chocolate chips until evenly dispersed throughout the batter. This step adds texture and ensures every bite is filled with cookie goodness.
5. Pour the brownie batter into the lined pan, smoothing the top with a spatula. Make sure it s level for even baking throughout.
6. Decorate by arranging whole Oreo cookies on top of the brownie batter, ensuring their designs are visible. This adds extra flair to your treats!
7. Bake for approximately 32 minutes. Check for doneness by inserting a toothpick; it should come out with a few moist crumbs for that perfect fudgy texture.
8. Cool the brownies in the pan for 10-15 minutes before lifting them out. This resting period helps them set, making it easier to cut into square bars.

Optional: Serve warm with a scoop of vanilla ice cream for an extra indulgent treat!
