Description

Celebrate Halloween with these spooky and delicious Halloween Oreo Cookie Boo Brownies. Featuring a fudgy brownie base topped with festive Halloween Oreos, these brownies are perfect for a seasonal treat that combines rich chocolatey goodness with fun, ghostly Oreo designs. Chilling the brownies enhances their chewy texture and highlights the Oreo and chocolate chip mix-ins, making them an irresistible dessert for any Halloween gathering.


Ingredients

Scale

Brownie Batter

  • 1 batch Oreo Brownies by Baker by Nature (includes standard brownie ingredients such as butter, sugar, eggs, flour, cocoa powder, chocolate chips, and crushed Oreos)

Topping

  • Halloween Boo Oreos, enough to place whole and in pieces on top of the batter before baking


Instructions

  1. Prepare the Pan: Line a 9×9 metal baking pan with parchment paper to ensure easy removal of the brownies after baking.
  2. Make the Brownie Batter: Follow the original Oreo Brownies recipe by Baker by Nature to prepare the batter thoroughly and evenly.
  3. Pour and Smooth Batter: Pour the prepared brownie batter into the lined pan and smooth out the top evenly using a spatula to create a flat surface.
  4. Add Halloween Oreos: Arrange Halloween Boo Oreos on top of the brownie batter with the spooky designs facing up. Place some whole Oreos and some larger Oreo pieces scattered to retain spooky patterns after baking.
  5. Bake the Brownies: Bake the brownies as directed in the Oreo Brownies recipe, typically around 30 minutes, until the top is shiny, slightly cracked, and edges are set without overbaking.
  6. Cool Completely: Allow the brownies to fully cool in the pan for about 2 hours to set the texture and prevent sticking during slicing.
  7. Slice Cleanly: Use a large chef’s knife to cut the brownies into bars. Press the knife down and lift up rather than dragging it to get clean lines. Wipe the knife between slices to avoid crumbs and sticking.
  8. Optional Serving Tip: Chill the brownies in the refrigerator to enjoy a chewier texture and intensified Oreo and chocolate chip flavors.

Notes

  • Do not overbake the brownies; watch for a shiny, slightly cracked top and firm edges as signs of doneness.
  • Place some larger Oreo pieces and some whole Oreos on top of the batter to preserve the spooky designs after baking.
  • Use a large chef’s knife to cut brownies cleanly by pressing down and lifting up rather than slicing and dragging; wipe the knife between cuts.
  • Let brownies cool completely before slicing to ensure they cut easily without sticking.
  • Chilling brownies enhances the chewy texture and makes the Oreo and chocolate chip flavors stand out more.
