Instructions

Preheat the oven to 350F then line an 8x8 inch baking pan with parchment paper and set aside.
In a microwave-safe bowl melt the butter, oil, and both sugars, together in 30-second intervals mixing in between every time. Once fully melted microwave for another 1 minute and stir vigorously to allow the sugar to melt fully. Using a hand mixer or stand mixer here is best.
2/3 cup butter, 1/4 cup vegetable oil, 1 cup granulated sugar, 1/3 cup brown sugar
Whisk in the eggs one at a time then add in the vanilla. You want the batter to pull from the bowl a little bit.
2 eggs, 1 tsp vanilla extract
Add in the flour, cocoa powder, and salt and fold just until combined.
1/2 tsp salt, 1/2 cup all purpose flour, 2/3 cup cocoa powder
Pour half of the batter into the parchment paper-lined baking pan and spread evenly.
Place the Oreos in the center of the batter (see photo) then top with the rest of the brownie batter and spread to cover.
15 Oreos
Top with the 5 crushed Oreos and bake in the preheated oven for 30 minutes.
Allow the brownies to cool down fully on a wire rack before slicing into them for the perfect square crinkle top slice every time.

Notes

Let them cool completely before slicing: At least a few hours on a wire rack. I wait 8 hours for the cleanest squares. Cut them warm and the Oreo layer smears.

Melt the sugar fully: The extra minute in the microwave and a hard stir dissolve the sugar, which is what gives you that shiny crinkle top.

Use regular Halloween Oreos: The ones with orange filling, not Double Stuf. Whole and halved Oreos go in the middle, crushed ones on top.

For clean cuts: Dip a sharp knife in hot water and wipe it dry between slices.

Storage: Airtight at room temperature for up to 5 days, or wrap and freeze for up to 3 months.
